This thread will be about video encoding, with the end product being the Raphael. My current Device, Radio and ROM are in my sig and updated for reference.
The premise of this guide: Using freely available (NON-WAREZ) CODEC and software, the user will be able to create video with audio playable on a HTC Touch Pro. The video will be of a watchable quality and small in file size.
Some of you may be familiar with my work on SEGA Dreamcast with GypPlay, DC-Divx, DC-VCD standard, and XDP (X-Rips, Inc. Dreampassport, English translation of DP 2 and above)

----- START OF THEOREY -----
If you're like me, the first thing you asked yourself after buying your Fuse was "HOLY ****! I can run 4x the storage on this thing that my old Wizard could!" Yes, 16 GB of Micro-SD goodness is freakin' sweet. But how to use it? You can only listen to so much music per week, even with Napster To Go. You can only play so many games. (I'm further reduced due to lack of a usable joy pad for Pocket Nester.) Why not throw some movies on this joker?
----- VIDEO FORMAT -----
The first thing most people want to know is "What resolution and format should I use?" I am a longtime fan of Divx. I have used it to successfully create video content for low end devices, specifically the SEGA Dreamcast. Creating or downsampling content for a mobile phone gives us a considerable edge over bigger-screen counterparts. Before we jump into the configuration of settings and knob-dicking with software, let's figure out just what kind of video we want to produce.
FRAME RATE
Most content you find will come in one of 3 frame rates:
30 FPS (VHS / NTSC Broadcast / DVD / Blu-Ray(?) )
25 FPS (PAL)
23.976 FPS (Actual frame rate used to record cinema and produce much media)
The first thing you need to realize is that many things initially encoded in 30 FPS can be converted back to 23.976 FPS with no loss of fluidity or data. If your source is a webcam, skip the scaling to 23.976 and drop down to frame decimation. If your source is film, you're in luck. The other frames are just dummy frames that waste a little data. Deleting those frames frees up more video data to better express the picture information in the other 23.976 frames. This trick allows you to:
A. Use a lower bitrate (and hence smaller file) for the same picture OR
B. Get a better picture at the current bitrate
To figure out the frame rate, load up your file in V-Dub and go to File - File Information. The Data Rate box in the Video Stream area will tell you current bit rate, while frame size will give you resolution and frame rate. If you have a 23.976 FPS source, continue. If you have a 30 FPS source that you think should be 23.976 FPS (Film, etc) :
1. Load up the file in V-Dub.
2. Go to the Video drop down menu. Select Frame Rate (CTL+R is shortcut)
3. Change the Frame Rate on the source to 23.976 FPS.
If you continue to have audio sync issues with this method, leave the file at 30 FPS and continue.
Now we are going to look at frame decimation. Frame decimation drops every X frame while keeping the audio sync'd. The end result is a file X the frame rate of the source. While this is noticeable on large screens, on the Touch Pro / Diamond Screens (and probably even the HD), it shouldn't be an issue at all. You can play with this option. It is more noticeable on film, but I cannot see a difference at all on animated sources.
I use the decimate by 2 option in VDub. Video -> Frame Rate (CTL+R shortcut) and select Decimate video frame rate by 2. Our output video is now half the frame rate of our source. The end result is we can:
A. Get a better picture with the current video bit rate OR
B. Lower the video bit rate to get the same picture in a smaller size.
I use option B. Another big advantage here is that the device is trying to decode half the frames. A general rule about audio and video playback: The lower the bit rate you ask the device to handle, the less work it has to do to decode and display the video, and less battery power will be used.
RESOLUTION
Most content you will find is around 640 x 480. DVD sources usually come around 720x480. Blu-Ray would be above that, but possibly scaled down. We are going to watch this movie on a 3 inch screen. Guess what that means? If we never found a video about 320x240, or comparable widescreen resolution, It wouldn't matter. At all. Stepping up to 640x480 is just going to quadruple the amount of pixels we are trying to express on a limited budget.
A handy tool I use in V-Dub is the 2:1 reduction filter (high quality). To kick kit on, go to Video -> Filters (CTL+F). Click add, and it should be the first filter you can choose. This cuts your resolution by half. As a rule of thumb, If I've got a source that's around 640x480 (or 16:9 equiv) or higher, I hit it with the 2:1. You'll find oddball sources like 480 x 360, you can give it a shot, but it might not be worth it. Again, lower resolution means less pixels to express both in bit rate and in reproduction (playback).
Pausing here again, tired as hell.

Okay, replies and requests, go!

Am I correct in thinking that videos should be encoded in 640 x 480 ?

Smaller would be sweeter.

Taking a break for a bit, added some new material. Internets in the hotel are barely functional.
I'll be focusing on getting files down to smaller levels. The theorey should give you enough information to start dramatically cutting your file sizes. I've been moving my Boondocks DVD over to Divx 6.8 movies. Averaging 40 megs per episode.

I have been using spb mobile dvd for a few years now. It is very easy to use can convert straight from a dvd or a video file and supports vga res.

Will have to check that one out, have been thinking about backing up my DVD's to mobile, will be traveling about 26 - 30 weeks out of the year and need some boredom killers.
Gonna score some sleep and SEGA time, later all.

Added some new info, taking a pre breakfast nap.

i use slysoft clonedvdmobile. output at vga res and filesize around 700mb seems to run fine for me...although its not free, its well worth the money

This is a great bit of software. It also utilises all 4 cores on my Q6600. Another fantastic program is DvDFab which can transcode DVD to Divx/Xvid/MP4 etc on the fly, or dump the Video TS to your HD.

Going to have to check all this out. Have many a DVD that needs ripped. Wonder if any of those have a frame decimation feature. I like my 30 - 40 meg per episode cartoons.

Based on some comments in other threads, I've tried a couple of freeware programs to try to encode in the format that works so well with WMP (MP4, H.264, 640x368, 1000 Kbps, AAC @ 96Kbps): DVD Decrypter + SUPER for one and AutoMKV for the other. However, I haven't been fully successful with either, so I'm hoping that someone who uses these tools can clue me in on the appropriate settings and procedures for encoding.
The combination of DVD Decrypter and SUPER creates very nice movies for playback on the Fuze. Unfortunately, DVD Decrypter keeps the VOB structure from the DVD and SUPER follows suit, which means that a movie will be broken into several pieces at arbitrary points: unsatisfactory, to say the least. The SUPER support forum mentions a way to join inputs into a single output, but following what I understood those instructions to say did not, in fact, result in a combined file.
AutoMKV is very convenient, as it is a single program (or at least UI) to both rip and encode. Unfortunately, I haven't found the settings that generate output that is comparable to the SUPER output -- WMP won't play any of the files I've managed to create so far.
Anybody use these successfully and can share how they do it? TIA.

amerisoft, works very well for me so far, except an occasional blank screen

Just wanted to add...
I don't bother encoding video anymore. Sure, a full-blown 50 minute xvid show might be 400meg. However, the touch pro does not have any issue playing such files back.
Makes life much easier!

I'd agree. I've loaded up a couple of 700MB XVIDs and had no problem playing them.

For some reason, my Sprint Touch Pro has issues playing back even reasonable quality video. For instance, 640x480 video at 1200k (MP4) is a little choppy in WMP, and almost -everything- is extremely choppy in TCPMP, no matter how it's encoded, including 350MB 45-minute XVid TV shows.

As I understand it, it's a driver issue. (This is what I've gathered across numerous postings here; someone please correct me if I've gotten something wrong.) The Qualcomm chipset in the TP/Fuze has an efficient driver called Qtv, but Qualcomm charges for a license. WMP appears to incorporate the driver, so it's able to handle moderately challenging videos. 1200 Kbps might be a little more than it's capable of displaying smoothly, but people have reported that 1000 Kbps plays well. On my one trial with DVD Decrypter + SUPER, that was the case for me, too -- full resolution and smooth motion for a video ripped from a DVD with the specs I reported in my earlier message in this thread.
TCPMP, on the other hand, does not include the Qtv driver, so in order to get smooth playback you have to reduce the size, resolution, or frame rate.
Coreplayer has a reverse-engineered partial driver for Qtv. As a result, it falls between TCPMP and WP in capabilities. It is claimed that version 3.0 of Coreplayer will have full Qtv support.

[Q] Best handbrake settings for Honeycomb 3.1?

I have a Handbrake profile saved from back in March. I found it from a YouTube video links section, where the author of the "how-to" video about re-encoding video for the best playback on the Xoom posted a link to a pretty good Handbrake preset for the Xoom.
I am just wondering... if video playback is now better in Honeycomb 3.1, if there would be a better setting (for better quality video) out there? Does anyone have a Handbrake preset that looks really good on the Xoom that is new for the 3.1 update?
The preset I have from March works well, and videos encoded using the preset play without stutter - but the quality is a bit blurry at times... which leads me to wonder if the Xoom couldn't handle higher quality video now.

I had lots of trouble finding the right combo with Handbrake. Videos would play fine but weren't very crisp.
Switched over to the latest version of an old app - DVD Fab. Works extremely well, videos are sharp and play buttery smooth.

JFMFT,
What setting are you currently using? I'm at work so cant check mine right now. I know whatever settings I was using seemed to work pretty well-will get back to you with specifics.

If you have a solid preset to tweak, then try using the "Constant Quality" setting under the "Video" tab:
Constant Quality - Handbrake
CRF Guide - Handbrake
Read the above links; they have great info. If you don't, then at least note that higher RF means lower quality (higher compression).
For me, a single Handbrake preset doesn't produce the results I want -- good quality balanced with decent file sizes -- across different kinds of video. Animation differs greatly from fast-paced action (frames, distinct lines/edges, blur, etc.), for example.
In Handbrake, I started with H264 baseline profile settings, then settled on some tweaks in the "Advanced" tab after some reading and experimentation:
Motorola Support FAQ: Motorola XOOM - Optimal video settings
HandBrake Docs (links to option descriptions): x264 Options - Handbrake
Now, I vary only the "Constant Quality" parameter between RF 19 and 25, depending on the type and quality of the source. It takes some trial and error, but I think it's a worthwhile effort. Working first with short samples (5-10 min) from the video source will help things move quicker, too.

Get RockPlayer, it literally plays everything.

Forget Handbrake / DVD Fab. Free vs Cost issue aside, DVD Catalyst 4 FTW!

Away from home currently, but I will check into my settings & report back soon.

try this one?

Here are my Handbrake settings for my Xoom.
I'm getting pretty good results in term of quality/size.
For the Picture settings, I'm changing the Anamorphic to None and setting the Width to 1280 (be sure to check the Keep Aspect ratio).
Maybe the Anamorphic could be changed to other, I didn't test to see the difference.
You can try setting Constant Quality or increase the Bitrate value (I'm using 1500 which seems to be enough)
Encoding is quite fast (depending of the PC of course)
Enjoy playing them with the default HC video player

"video playback is now better in Honeycomb 3.1" i agree. Honeycomb 3.1 improve the hardware capabilities, so video will play more smoothly. but for video conversion, you need to increase the bit rate. this is my own experience.

Rogers Infuse records video at 15 fps!

Hey guys i'm posting this thread to reply to a thread in the dev's section.
Since i'm a new member with under 10 posts i cannot reply to the thread in that section. Here's the thread url:

Misterjunky wanted to know if the Rogers i997 phones with Gingerbread 2.3.3 were having the same low fps recording issues as others that have complained about it.
I am here to confirm that yes, i bought the phone last week and it does in fact record video only at 15 fps, even at 1080p.
This is very frustrating!

Thank you for letting us know!
I hope we can get ot fixed

Yep, I notice the same problem. After i rooted my phone and install infused 2.1.0 and did a highest resolution recording today, notice that it is it has latency slow fps. Absolutely horrible.

Hi all,
Another Rogers User here with the same low fps issue when recording movies. I also am replying here since I can't post in the developer forum.
Had the infuse for about a month, but just recorded my first video on it yesterday and noticed the clearly low fps.
Stock infuse, no roms.

Good to know that it isn't a regression we introduced.
The media capabilities of the Rogers firmware are clearly crippled - no MHL, low FPS for video.

Same here, Rogers stock 2.3.3 ... getting half frames

I couldn't get the method to work, whenever I try to copy the 4 files into that directory (via Root Explorer) I get a error window saying it cant be done because that directory is system read only. Any thoughts?
My Infuse is from Rogers, and yes I have root from this method: http://forum.xda-developers.com/showthread.php?t=1197248
Edit: OK the problem is fixed. While in the folder with the original files I pressed the "mount R/W" button at the top of Root Explorer and tried to paste the four modded files but got that "read only" error. For some reason doing it to the system folder first, then going to the lib folder and doing it there made it work. The video recording is simply epic!

Help with recording constant frame rate video on the HTC Desire S

I have been trying to get the most out of the camera of my HTC Desire S in terms of video quality, and now I am able to record 720p [email protected] Mbps. The vanilla camera app(rooted stock 2.3.5 ROM) records [email protected], so it is nice improvement.
I am using an app called IgCamera, it has lots of options for customization(bitrate, frame rate, codec, etc.), and I have modified the /system/etc/media_profiles.xml to increase the H264 encoder bitrate cap. It was set to 8Mbps in vanilla, I bumped it up to 24Mbps, but I have found out, that the maximum bitrate the phone can handle is 12 Mbps, any higher and the camera app freezes, and the camera cannot be used until reboot.
Now, I am looking for a way to force a constant 30 FPS. Currently, the videos are recorded with variable frame rate, and VFR is nasty for any kind of video editing. I have tried setting both the minimum and maximum frame rates in media_profiles.xml, in the encoder caps section(it seems to be the only one that affects IgCamera in any manner), but I am still getting a variable frame rate video.
Has anyone done something similar? I would appreciate any information on making a phone record CFR.

🎥 A better Slow Motion Recording Experience►

Hello, everyone‼:laugh:
Thank you for reading this.
Almost any phone of today has a Slow-Motion / High-Framerate feature.
Well, i've got nothing agianst it but there's something about it that truly sucks.
Here's my old thread about this.
The Bad method:
You Record: 00H:00M:10s@240fps (Resolution doesn't matter)
You get a Video with 80 Seconds @ 30fps
...and Muted Audio ♫♪
So that ►x1.0 isn't realtime!
Well, the iPhones record in realtime, but they can only record for 20 Seconds (real time equilevant)
kryz70fr said:
With the iPhone 5S camera software, you can edit your video to active slowmotion or not on the timeline ... how to do this with the Note 3?
Click to expand...
Click to collapse
Yes, you're right!
...but the Smartphones which use the sucking method of taking Slow-Motion Videos encode the output file being Slown Down.
The one and only advantage of this method, is for Media-Players which haven't got a Fast/Slow motion playback mode so that ►x1.0 makes the Slow Motion Effect Visible.
But i'd like to have ►x1.0 is Realtime-Equivalent!
So the Correct way in my opinion [IMO] is this:
If you Record 00:00:[email protected]
The Output File must be also 00:00:10 encoded at 204FPS and with ♪♫ Audio from ALL Microphones of the Phone!
Also some other Devices use the WRONG Method:
Lumix FƵ1000 - Great Camera but Slow Motion Feature uses WRONG WAY.
Canon IXUS 255 HS
But those Devices use a Good Method!
Sony RX100/3
Canon Powershot 510HS and 50HS
Sony FDR-AX100
Samsung NX1 (i think)
Example Videos ? :
Good
Only 720p BUT
XAVCS
And Audio
And Realtime
BAD
1080p but...
No XAVCS
Not Realtime
Muted Audio
Sucks
All Example Videos are taken by DKamera.dé!
Feel free posting your opinion! :laugh:
All the best Have a good and nice day ...

High Framerate Recording
Has anybody an Opinion about this?
There are many users who want Audio on Slow-Motion.
That, what i described there ↑↑↑, also covers this.
I'd be thankful for some feedback on my suggestion.
It's also nice, if every media player in the world has following features:
Speed Up / Slow Down
If adjust speed, enable/disable adjusting Sound Pitch
...so that 120FPS with output file encoded to 30FPS and muted sound is not there anymore
With ►x1.0 i mean Original Playback Speed of the Output File.
I'd always like to have 1.0x Playback Speed being Realtime-equivalent and Sound from every microphone that the device has (not just 2), independent from the Video's Framarate . (And no time limit until the Deices Battery/Storage runs out)
Example: Samsung's Galaxy Note 3 and Note 4 have 3 Microphones. But they do only use them all for the Sound-Memo and only 2 for video recording. They also record Slow-Motion the wrong way
Feel free giving your Feedback

Slow Motion - Redefined :·) (•:
I'd always like the Output file being always RealTime ►x1.0
That means, that i'd always like to get an Output File to be Real-Time-equivalent at x1.0 Playback Speed.
►1.0 to be Real Time Speed
And surely Audio from all Microphones of the device
(In FLAC Format, 1.6 Mbit/S )
(See Video04.Mp4✔)

Just like [email protected]
If i record 00:00:[email protected] then i'd also like to have an output file with 0:00:[email protected]FPS with sound.
...and not 00:00:[email protected]FPS without sound.
It feels like Recording REAL [email protected]FPS, i don't know how to explain.
Just like normal Video Recording but with a Higher Framerate - not additionally encoded to be slown down so that Original ►x1.0 Playback Speed is 0.25x Real Time Speed or 0.125x.

The slow motion clips might look cool on your iPhone, but they look quite disappointing on a TV or a monitor. Which reminds us of our other disappointment about the feature – when we tried to play those iPhone 5s slo-mo videos on a PC we found that unlike all previous slow motion-capable smartphones, the iPhone 5s actually encodes the video at 120 fps and your computer will play it on 120fps unless you explicitly force it to slow the video four times in order to achieve the desired slow-motion effect. It would have been way more natural the iPhone 5s to process the frames and output a standard 30fps video as most of the phones do, which doesn’t require special players and tools to play properly.

They've got another Opinion. But their described opinion is caused by the only advantage of the sucking way to take Slow-Motion Videos.
Here’s hoping Apple fixes this promptly with an update – it certainly can’t be that hard.

I hope not so lol

Sensor output / Output File
The Output File should have the same framerate, as the Sensor is Capturing.
(Exceptionally HDR-Video. HDR Video needs a Higher Framerate/Sensor Speed but the Outputfile is still Realtime at ►x1.0 )

Wow, really? Not mentioned befre?
But yes, it will be very useful :laugh:
Many Smartphone Manufacturers write in their User Manuals, that Slow Motion Recording with Audio {Sound} Recording is not possible.
So why don't manufacturers simply use the method for Slow Motion Videos that i Described?
Maybe it's just because of the „One and Only advantge of the Sucking way to take Slow Motion Videos:“
Not every player has an Adjustable Playback Speed--.....
The Galaxy K Ƶooom has also a Menu Option for PlayBack Speed for the Ouptut File.
But you only can use the 120FPS-Mode @ ¼ or ⅛ Speed for Output File, but i'd prefer it always to be x1.
I'd like 1x Playback Speed to be Real-Time Equilevant.
Accordingly, Every Player should have a Manually Settable Playback Speed, Sound Pinch, Reverse and Recording Feature.
VLC Media Player has ¾ it all - exceptionally the Reverse◄ Playback Feature.
If manufacturers fix this slow motion problem, have fun

Optical Flow / If you really want... / Video Converting,, Video Converters, Applicato

This iOS-App uses Optical Flow.
I hope this app also uses ?▶► Real Slow Motion...
If you REALLY want the Output file to be not ►1.o Realtime, then you can convert it after recording it into a second file.
There are Programs to do that.

The NX1 also uses the Wrong way.

There's a very high Request on Slow Motion-Audio and being able to adjust the Playback Speed in the Media Player.
http://forums.androidcentral.com/samsung-galaxy-note-4/464112-slow-motion-video-sound.html
I also don't understand, why manufacturers use the Way for taking Slow Motion Videos that i mentioned, because the other frequent way sucks.
Isn't there an app, which can record slow-motion videos the way i mentioned?
However, the iPhones only use Mono-Audio for any kind of Video-Recording. Horrible.
Sony:
Their Cameras (RX100 and FDR-AX100E etc.) record slow Motion the Proper Way. Congratiulations!
But their Smartphones only allow editing before saving - once saved, you can't adjust any speeds anymore.
Canon:
Newer models like SX50 HS and 510 HS use the right way - even for 240 fps - no specific time limit!. Respect!
But the beautiful SX255 HS also sucks recording them - 120 and 240 fps. And there's a limit of 20 Seconds (in Real-Time.)
Conclusion:
There are many - also free Video-Editing Programs for adjust the speed and Sound-Pitch (Pitchbend) of vidéos - so there's (almost) no reason for the (i call it the sucking way) of recording slow motion videos. (Only reason is the missing Playback Speed Pitch in many Media Players. S5+ aka S5 LTE A had it - from x0.5 up to x1.5 Playback Speed - even for 4k-Videos up to 61.2 mBit/s Bitrate!)
And also - setting playback is a small additional step before enjoying the Motion but if this step is too much, you're lazy.

Galaxy S6
Finally Samsung did it:
I'm rather disappointed from the S6 (http://forum.xda-developers.com/showthread.php?t=3044369 )
but finally, the Galaxy S6 does the RIGHT WAY of Slow Motion Recording.
Thanks god!!!!!!

Finally, in Slow motion mode the camera goes back up to 48Mbps but is now shooting 720p @ 120fps. Videos are actually recorded at 120fps, but you can edit them on the phone - trim beginning and end and choose between half, quarter and eighth playback speed. Here's how it looks when we drop to 30fps (playing at a quarter of real time speed).

I hope the Slow Motion also includes Audio.

Confirmed:
The S6 records Slow Motion WITH Audio and Realtime - like iPhone and SX50 and 510 HS and also RX100m3 (aka RX100 III)

I was reading a Review on GSMArena.
Then i saw this:
A note about formats - the iPhone records and saves 720p videos with 240fps framerate so you'll need to either edit them on the phone to create the slowdown effect or use a video editor on your computer, just copying them would only get you an extra smooth normal speed video. The Galaxy Alpha videos are slowed down to 30fps so the slow motion is easy to share. There's an option to slow the videos down to 15fps, which matches the iPhones 8x slowdown but the result isn't as smooth

With the Galaxy S6, Samsung finally goes the Right way, because you can Export a Version of your Video, that is actually Edited and Costumized yourself, to share or so...
It's always recomennded to keep the Original Slow Motion Video File with the Audio and the Real-Time.
The Galaxy S6 has no MicroSD-Card, no Changable battery, etc........
But in Slow Motion, the Galaxy S6 is finally the right thing.
I mentioned the Galaxy S6-Disadvantages right here.
The FDR-AX100E also uses the right way.

The Exporting Feature in the Video editor isn't even at the iPhones.
I wish, Samsung already did this with a good phone like the Note 3 or so...

Asks me for Desired Playback Speed? Lol....
Hannah said:
"Playback-Framerate" should be like "Shooting Frame Rate"
and "Time shot in Seconds" should be exactly identical as "Clip Playback Time"
And also, all Microphones should be used, to record the video.
Understand, what i mean?

For Galaxy S6 users (very rare):
Too bad, that so many older phones cam't set the playback speed in the mediaplayer, so if there's trouble, sharing your high-framerate-videos, you can edit the parts with the lower playback speed and export the shareable video, and keep the original real-time HFR Clip.
That's exactly, what i wish, every manufactueres do.
Simply make a Video Editor and Set Playback Speed, instead of recording the HFR Video the wrong "sucking" way.....

Well, the iPhones record in realtime, but they can only record for 20 Seconds (real time equilevant)

LG G3, G4 and Oppo Find 7 also apply with my standards.

Doesn't the VLC beta have the slow down / speed up controls

Maybe it's just because of the New Design. In the Extras (or Tools) you can costumize the VLC-Design/User Interface or go to the Playback-Menu.
Try with this file:

This Video File does comply with the Standards.

Treat like normal
I just like this type of recording the videos at a high framerate, because it treats Video Recording with a high fromerate as normal video recording. Just with a higher framerate.
Many devices have the ability to treat 1080p with 60 fps as normal video recording.

I was wondering if there's a posibility to record in slow-mo with my K900...
