How to reduce size for mp4 format videos taken by O3D? - LG Optimus 3D

...so yesterday I filmed fireworks underneath London Eye, since it lasts for 13min in size it's 1.4GB, I wanted to reduce it's size to smaller to put it on youtube, otherwise I'm at the moment with broadband and they are really unstable regarding connect. I tried vegas 7.0, but for some reason it doesn't recognize .mp4 file and sometimes it does recognize but makes this 13min video into 108h video and then it just freezes (app).
any ideas?
Happy New Year to everyone by the way!

You can use virtualdubmod on a windows pc. Load the video into it and save the video as an avi with xvid compression. Virtualdubmod and the xvid codec are both freeware and googling them will find the download links for you.
Also if you want to edit the video virtualdubmod can do that easily.

You can use this free windows program http://sourceforge.net/projects/mp4cam2avi/ to patch video header and make it a standard mp4 that any software can open

tried this app, but it doesn't shrink size, just convert into AVI, that's all. Thanks anyway.

for some reason it can't recognize .mp4 video what I filmed with O3D and tried the other recommended app which turns .mp4 into .avi's and it still shows some error about:
Couldn't find decompressor for format 'H264' (unknown)

The mpeg4avi program only fixes the video header so any software will read it as a h264 mpeg four video file.
After patching it you can use the new version, it defaults to calling it videout.avi, in any progran to edit it.
If your choice of program can't read it you just need to install a h264 codec like this one at http://sourceforge.net/projects/x264vfw/ as that lets virtualdub see the video.
Basically you need a h264 codec, an xvid codec, virtualdubmod and all you do then is....
1. In virtualdubmod choose open file option and load your video
2. For compression choose xvid and set it how you want or leave it at its default setting
3. Choose to save avi. It will reduce size based on your settings for compression.

tnx, it cut size in bout half, but still 700mb for 11min, tried to edit it in Vegas 7.0, but it just recognize only sound, not picture.

Vegas nay need a direct show h264 filter like the free ffmpeg one as opposed to the vfw one I linked to.
You can get hd video down to about four hundred megabytes by trying different settings such as lower bitrate in xvid or setting it to have a quantiser of more than 1. The easiest way is encode a short thirty second clip in virtualdub to test different settings. On youtube some similar length hd videos are as small as 250 mb but it depends on your compression settings mainly.

You have to have full processing on. It can only be off for things like converting framerate that do not require changes to the actual video itself. But you should be able to get good results with bitrates as low as 1500 k its just a case of finding compression settings you prefer.

With Rockplayer from the Android Market you woun't ever have to convert a video again. It plays all formats including mkv out of the box!
Sent from my X10i using Tapatalk
I use SUPER ©
Yes use Rockplayer
After second "Rockplayer" - it really does away with having to spend hours converting "most" movies
somebody really still converting?
Yes, I still do it, because movies take less space on my SD card once they are in MP4 (with the right format) instead of original format.
I cannot change movies every nigth, I have to store 6 or 7 for the week... (and music, and pictures, and...)
thank you
thank you guys
i will try it all..
and yaa instead of direct copy i prefer to convert it becoz it take less memory on my SD card thats why
but you can save much time with bigger sd-card an the rockplayer...

So which media player is good to play HD video in MP4 format? Rockplayer or Super?
Guys,
I have tried handbrake to encode and Rockplayer, realplayer beta to playback the below video clip :

With no success and the video become stuck when it reached : 2:44
Let me know if anyone can overcome this problem, thanks.

SUPER is NOT a media player, its a video converter to use in your PC.
on my X10i (unbranded) the SE Mediascape video player plays better than Rock player, the sound is in sync more than Rock player for example.
I have also used "IM TOO" but found it very slow. (1.5 hours to encode a 30 minute episode of Alan Partridge.
I now use WinX DVD Ripper winxdvd d0t c0m (no I dont work for them).
If this is spyware or whatever please let me know, but in encodes a DVD film in 45 mins (even a Disney one with all that special encoding)
My question is....
"what is the ultimate setting for encoding a DVD to MP4 for the X10i?
Please do not reply if you are just guessing, the X10i does not like frame rate 30 for example..
thanks
x2 on using Super as the video convertor. It's free and it offers more features than most other video convertors.
but with RockPlayer (and yxplayer for some files) I no longer need to convert. my 16gb only stores documents, some pictures, and videos but no mp3 since i'd rather listen to streaming internet radio than download mp3s.
the "best" video setting will depend on how you rate video quality. imo, for smoothness and when you are watching movies, i'd go with 23 fps or less, and have high bitrate but reduced resolution (above half the resolution of the lcd display).
video conversion speeds depends mainly on your video converting settings (format, bitrate, resolution, etc.) and your CPU power, not the software.. just fyi.
I am currently using xmedia recode.
I use the settings for the Motorola Milestone when converting, as for some reason the X10 settings mess the audio up.
Pretty quick, and audio/visual sync is spot on
It doesn't matter what to use.
for example, I convert films from my 720p/1080p hd collection, using parameters, such as 854x480 resolution, 160 kbit audio bitrate and 1000-1200 kbit video bitrate.
And it looks like I watch a real hd video! The picture is perfect! Enjoy
Oh, and I noticed, that it's better to use h264 codecs with *.mkv container than mpeg4 with .mp4 and .avi
RockPlayer is the best for my monster-like videos Avatar with 1200 video bitrate and near 2gb file size works without any lags. This is the power of nice program code (thx for RockPlayer devs) with the connection of Snapdragon processor

Question: Movies on cappy?

i got some 700mb avi movies and dropped it on my phone. it said it could not play. do i need to resize it or is it an encoder issue? maybe the file size is too big? idk!
thanks
What player are you trying to use?
use rockplayer or vplayer, I had played 2.7gb mkv 720p movie with no issue.

Try the program "handbrake" with high profile settings
Are you using a custom rom? Because I have been watching 700 mb .avi and great big hd .mkv with no problem, on both stock and newest cognition. Only format I HAVE had a problem with is m2ts.
I use PavTube Ultimate Blu-Ray Converter to make Xvid MP4 files out of my discs. They work great on the Captivate. I played around with different settings and there really isn't much visual difference between using the native 800x480 resolution compared to HD rez, but the difference in file size is significant.
I get the same issues with some AVI's in both Rockplayer and the stock player on the stock rom. Haven't tried movies since flashing to Cognition 2.3b7. MKV's don't typically play in rockplayer, the few that have skipped a ton, or they would play with no audio. Not sure what you guys are doing to your movies to make them play. All of my videos are encoded properly, and play on my WD TV Live just fine. The WD is a good test of media quality for rips.
The WD TV Live also can play pretty much any audio and video codec you throw at it.

There have been mkv's that have not played correctly on it, so if it's not encoded properly, the WD is a good test, from my experience.
I have some 700mb xvid movies on my phone and they play fine on stock rom w/stock player. But I highly recommend vplayer for video and rtsp watching.
Yep. Gave Handbrake a shot. Works like a charm. Will download vplayer and check it out
thanks fellas
What kind of settings are you guys using for your conversions?
Sent from my SAMSUNG-SGH-I897 using XDA App
followed the settings outlined on this webpage:
http://www.knowyourcell.com/samsung/samsung-captivate/captivate-guides/513592/how_to_convert_videos_and_transfer_them_to_the_samsung_captivate.html
Requirements:
Installed copy of Handbrake software
Video files and or DVD of your choice
Samsung Captivate with microUSB cable
Step I: Launch the Handbrake application on your computer and select the video source
In the menu on the right-hand side, select the iPod Legacy preset (figure 1)
Select your video source by clicking on the Source dropdown menu (we used a DVD for our testing purposes)
Select the destination and name for the file once it has been converted (both the .mp4 and .m4v extension work for the Captivate)
Confirm that the container is set to MP4 File and that Large file size, Web optimized, and iPod 5G support are unchecked
Step II: Adjust Handbrake's Video Settings
Picture Tab:
Uncheck Keep Aspect Ratio
Set the Captivated Width and Height (the Captivate supports a maximum of 800 x 480 pixels)
Video Tab:
Confirm the Video Codec is set as H.264 (x264)
Framerate (FPS) should be set to Same as source
Under Quality, select the Avg Bitrate (kbps) and change it to 1500
Step III: Adjust audio settings
Confirm the Audio Codec is AAC (faac)
Mixdown should be set to Stereo
Change the Samplerate to 48
Change the Bitrate to 160
Step IV: Save as a preset for future use
Click on the Presets menu and select New Preset
Enter Captivate in the dialog box and click Add
"Captivate" will now be saved as a preset and listed on the right hand side in Handbrake to be used in the future
Step V: Convert the video and copy to your Captivate
Click on the Start button in Handbrake
A command line/DOS window will open and start to process the video conversion
Once the conversion is done, mount your Captivate on to your computer via USB
Once mounted, create a folder named Video in the root folder on the Captivate
Copy converted file into the Video folder
That's it! The converted video can now be played on your Captivate using the Gallery app. It should look fantastic on the Captivate's screen as long as the original source was of good quality.
A few things to keep in mind when converting video:
The Captivate does not like video file sizes over 2GB (the settings in Step II should help insure that the file size is kept under 2GB)
Your converted video will only be as good as the source video
If your source is over 800 x 480, you must be sure to set the width and height to a maximum of 800 x 480 as noted in Step II

Tried Handbrake using the settings above and the video was garbage. I'll stick with Pavtube as it converts anything I throw at it in any format without issue and it does Blu-Ray, as well. Looks like 1500 bit rate is the sweet spot for good video quality and manageable file size.
I believe all you have to click is High profile on the right side , that is it

I don't think u would need to convert any vids for the captivate. Captivate by itself plays a variety of formats
Actually, since I'm ripping mostly Blu-Ray discs, they DO need to be converted. And I did a check ripping standard DVD to both mpg2 and mp4. A 50mb mpg2 rip was about 3:40 (min:seconds) whereas the same settings ripped to mp4 was closer to 4:20. Over the span of a complete movie, the mp4 conversion will yield a smaller file size.

[Q] Best format for video

What is the best for playing movies? I plan to rip some from Dvds, and wondered what would play best. I am using Vegan 3. I dont know much about divx vs other codecs.
I use mp4 I have 22 video and they only take 20gb of space. I have heard of guys using .mov but I think it is a full 1080 few so it will probably use a lot more space. I think mp4 is only 720 capable

Handbrakes stock settings work fine for me I tried anyvideoconverter but converted files gave corrupt error
Depends on the source. DVD = standard video, so I would actually recommend Xvid in an AVI container. They play very nicely, plus it's a pretty standard format. And for problematic AC3 audio, you can use an app like Rockplayer. MKV also works nicely in Rockplayer. Or you can even encode to MP4 if you want iPod / iPad compatibility.
For High-Def, I would personally recommend MP4 (h263), only because h264 is so problematic. I use Handbrake and then alter the iPad Profile from h264 to MP4 (h263) and it works very nicely on our device. Yes, it's not "standard" so my files are really only for this device or my PC.
I'm not an expert on video formats or ripping/converting. However, I've spent the last couple of days (off and on) trying to find the best way to get vids on the gTab. As of this morning, the best option I've found is using Pazera. I used the "Video to iPod" converter with the following settings:
Output file format
MP4 (MPEG-4/AAC)
Bitrate: 1000 kbit/s
FPS: 30
Audio - Left it in "Auto"
Advanced Settings
Resolution: 1280 x 720 - HD720
The quality looks really good. No issues with the audio either. My only problem is the file size is 1.2GB. The vid I converted was 2 1/2 hours but I still think I want the file size around 500 to 700MB. I'm going to adjust the settings some more and see if I can find the balance between video quality and file size. It just takes an hour or so to convert it so this may take a few days.
I hope this is helpful to everyone. If anyone else has any experience with Pazera and can recommend good settings, I'm all ears!
Sly Soft's AnyDVD to rip and them AnyDVDMobile to convert (I use ipad's default settings on the mobile conversion and they work great - I use those settings b/c I my kids use the same rips for the ipod touch and it comes out as something they all can use (rather than keeping multiple copies for each device).
I have been using this to convert HD video into something the hardware decoder can play without issue:
Code:
INPUT="My_movie.mkv"
OUTPUT="My_movie-gtab.mp4"
ABITRATE=64k
VBITRATE=1500k
RESIZETO="-s 1024x576"
ffmpeg -strict experimental -y -i $INPUT -f mp4 $RESIZETO -vcodec libx264 \
-vpre default -vpre ipod640 -acodec aac -ab $ABITRATE \
-ac 2 -b $VBITRATE -threads 0 $OUTPUT
1000k for the video bitrate would net you about 480M/hour, with 1500k at about 700M/hour (which is fine by me).
The RESIZETO will work for 720p and 1080p content as it's resizing for the longer width. If you have SD content (DVDs) just comment out the RESIZETO. If you have something that is anamorphic (check ffmpeg -i $FILENAME) you will need to do your own math, or just leave it and up the bitrate. A good rule of thumb for high quality is:
0.14 * Height * Width * frames/sec
So 0.14 * 576 * 1024 * 29.97 = 2477260bps, or ~ 2500k, about 1.1G/hour
adjusting the number downward will reduce quality, but it's a choice between video quality and size at this point.
I have tested this with a few videos (Big Buck Bunny, originally 1080p content) and with some 720p videos. 1500k worked out really well.
Great info ckelly33 and ckelly. I'm starting to think the question is more on "what are the acceptable formats". Everyone is different and the output they are looking for is just as different. I'm still trying for 500 to 700MB.
I tried again and I think I've got it like I want it. Need to test it some more. On the last conversion I noticed a button for max file size. That got me right where I want to be!

So far, It has accepted mp4 and avi containers (I prefer mp4), as well as mp3/aac for audio and h.264(main profile). Reports from roebeet says h.263 works as well. I have not tested xvid yet. I had issues with ac3 audio, so I don't think it supports that.
Of all of those, h.264 is a very very high quality codec, so I would recommend trying to use h.264/aac for encoding if at all possible.

Im trying to watch either .mp4 or .mkv but both lag in stock player and moboplayer. Anybody get this to work with zero lag?

If the movies you're trying to watch are encoded with High profile then playback will be laggy no matter what on the TF.

Okay I'm a new when it comes ti all these video formats.. all I know is that I get choppy playback
So this handles 1080 but with some tweaks I'm assuming..again, I'm a new at this
Were those movies you converted? Is so you mind writing up a little tutorial
Thanks
For the MKV, I downloaded it was already encoded so I am not sure of its specs, but the playback quality and resolution are excellent even on my desktop's 24" HD monitors.
For the MP4 played at the beginning of the video, that was shot in 1920x1080, brought into Premiere CS5 for editing and exported through Adobe Media Encoder using H.264 at 1280x720.
There are some threads with Handbrake encoding specs on the forums as well.
When using Vital player make sure the Decode Mode settings are set to automatic. It will automatically recognize there is no hardware acceleration (as I understand is normal with the Tegra-2). It will then compensate with "software acceleration". Also in the Video Mode settings I have it set to speed over quality as the performance is better without sacrificing much of the quality to my eye.
With these settings, Vital Player should play just about any video you might download off of a torrent site. I have yet to find a video that does not play well through it. I'm not sure if other users who say it does not work for them have checked the Vital Player settings, if my videos are just not up to the elusive "high profile" they are talking about, or if I just have a rare Transformer that just works, but as you can see in the video it does work for me.

So you had to encode the mkv or mp4 before playback? So it cant just play them straight up?
Sent from my Transformer TF101 using XDA Premium App
I believe that nearly any video you get is going to need be encoded in some form at some time.
The MKV was more than likely encoded by someone else before I downloaded, but no further encoding was necessary on my end. The MP4 was shot on my own camera (Canon 7D recording at 1920x1080p) and needed to be edited. When you export directly from the timeline in Premiere, it must be encoded to even be usable. For sites like YouTube or Vimeo to even accept them there must be encoding. The H.264 encoding that I used is the highest setting for that type of video's purpose (HD web playback). It is different than what I would have exported for burning to Blu-Ray but is adequate for a screen the size and resolution of the Transformer's.
When I return home, I will try bringing in the raw, unedited video from the 7D (which is around 3GB for a 4 minute vid at that resolution btw) and see if Vital Player plays it back with no lag. I seriously doubt it as some average computers have a hard time playing that back without lag. Even Final Cut Pro can't import raw 7D video without a conversion (Adobe Premiere does not have this problem though). Why anyone would want to play a video of this size and resolution on a tablet is beyond me (3GB for 4mins is ridiculous in a playback form). I can't even imagine wanting to watch a full length movie in that form.
Both of these videos seriously choke in any player other than Vital Player (including Mobo, QQ, and MVideo). I couldn't play any video in my library with them or the stock player, but all of these files play just fine in Vital.

90% of all HD videos you download the internet are ripped from blu-ray and likely encoded with high profile h264 because that's what looks best. the tegra 2 cannot handle these files at 720 or 1080p, and thus they need to be re-encoded to main profile, which as i understand it, means a much lower bitrate (and thus worse picture).

Thanks guys

I got all excited because of this thread...but I just gave VitalPlayer a shot on a 720p high profile x264 and it still sucks. No artifacts but the framerate is really low it seems.
In case anyone is interested I did receive this message from ASUS:
"On this issue, we have tested some of the 1080p video is playing well. We have cooperation with google and will launch android 3.1 in June to resolve the 720p and 1080p video playback problems."
We'll see...

i believe that is flash only, as in 720/1080 youtube streaming which is much lower quality than a high profile blu-ray rip. the problem is tegra 2, which is a year old, not supporting 720/1080p playback. it's the reason boxee box dropped tegra for an intel chip.

this thread seems to do a pretty good job of explaining everything and going through how to get HD vids working

Mirror high quality mkv video without skips

I had this issue with 720p and 1080 mkv files I downloaded mirroring correctly on my Atrix 2, the video would be jerky.
The problem was because the atrix 2 doesnt play well with 48khz audio.
The following steps will make 720 mkv or 1080 mkv play smoothly on the atrix 2 without any video reencoding, just audio.
It is a two program process, which produces great results.
The first program is MeGUI
The second program is xenonmkv
I attached my atrix 2 presets for megui which you can import into megui if you want to skip all the setting stuff below.
Xenonmkv just changes stuff in the mkv file and turns the file into mp4 which I find plays better on the Atrix 2
Step one, in MeGui, I go to tools and then One Click Encoder, Load the input file,
then show advanced options, under advanced options check keep input resolution, under Encoder options check dont encode video, under audio select NeroAAC, then config, then under sample rate Select Change to 44100 hz , I alse set the audio bitrate to 128kb. I save all these settings as a profile so next time I just load file and click encode and bam done.
If you are doing more then one file just make "and open next" is selected under MeGUI one click encoder.
Once you are done you just go to Queue and click start.
Once all the files are encoded load up xenonmkv, and load the file and click start, itll convert to a mp4 without actually reencoding the video and in the end you have a mkv that plays smooth on the atrix 2.
