Coreplayer divx quality

Hi there,
I was watching yesterday a divx movie (320 X 240) using Coreplayer on my new IPAQ 614c.
1) I was surprised to see kind of stripes (evidenced in the black background (top right panel), see attached file). I have to say that I do not have this pattern on other devices (tested on a Dell and Eten PPC) using the same software and movie.
2) Changing the color profile (to native) helped. So is it the reason for this difference observed an other devices.
3) This does not happen for all movies. As such, some other movies (also in 640X480) just run very nicely. Therefore, I believe this has nothing to do with the hardware.
Do U also experience this?
Any feedback appreciated

Nobody?
Thanks

never heard about or seen the issue but then i dont watch movies really on my device
but in TCPMP the free version of coreplayer one can choose different drivers for play back i if i were you would try and see if changing the driver in coreplayer had any effect

I watched wanted on my Athena (VGA) on a plane last week and it was fine, no jaggediness, or black lines, and that is a pretty dark film too.

I've watched a few TV episodes and some Bourne, really good quality though. Only thing I'm trying to work out is the A/V offset.

Thanks for the answers...
I will try to play with the drivers.
Anyway, I was looking at the same episode in 640X480 and had no black line at all...
So strange

Looks like it is better choosing IntelXScale as a driver...
Also the benckmarks are better with these drivers...
Will put later this afternoon the different benchmarks.
Thanks again

Discussion over
I do not know why but I did not have IntelXscale selected (I think I was playing a bit too much with the options).
Anyway, the problem is solved now using this driver.
Also, a benchmark with the well-known Matrix trailer (640X352, Bitrate: 127 kb/s) gives nice results:
DirectDraw: 94.93%
IntelXscale: 216.58%
GDI: 106.57%

i just got the new coreplayer and it only shows the tytn2 driver..
is this better or is there somewere i could get this interxscale driver?
just playd a video that comes allong with the xperia, as a video sample
benchmark results were
Average speed 62,50%
Original data rate = 922 kbit/s
Bench. data rate = 576 kbit/s

maybe the IntelXscale dont show up because you dont have an intel xscale cpu
but an qualcomm ?

----- 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.

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

I just use the standard 700mb divx movie in .avi
I use the free divx player V0.91
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.

Why wm sucks to play mp4 video?

AS after searching and doing for last two years i now come to a conclusion that wm sucks on mp4 video..
no matter we use coreplayer ir wmp..
any solution?

What resolution, bitrate, type of videofile(not mp4, thats just a container) I've actually had some very good experiences playing many mp4 files back on my ipaq 210 at around vga, all work flawlessly. Maybe time to upgrade your elfin?

blame qualcomm or texas instruments for their technology
intel is better still

Think that it's more to do with how you encode your movies rather than WM as i recode to .mp4 and have good quality on all devices via CorePlayer, Wanted\Ghost In The Shell 2 Innocence\Sky Blue to which are what i tend to test a new phone with all running perfect.
I use DVD Catalyst or FLVtoAVI "the name means nothing does everything" depends on device.
Resolution of device, keeping same fps as source, keeping the audio bitrate down to save space as it's easier then for phone to read less in chunks, then video bitrate.
Once you find the optimum settings for your software then it's all plane sailing
Your device is slow CPU wise same as Excalibur so can't expect amazing results and having a faster CPU makes a lot of difference when movies concerned.

hummmm.
ok.i have download a video "street fighters 4 gameplay" from savevidcom which give option to dwnld as flv,mp4,hd...
now my benchmark for that video from coreplayer is like this.
frame rate 29.996
sample rate 441000
data rate 653kbit/s

What resolution is that running at? And is it any faster. I personally use avidemux to convert videos because its free and has tons of options. Another thing to try is to convert it with 23fps, can't even tell the difference

Thing is benchmark doesn't show quality as such will show how well your device will play the file but the original source file or recode file will be the quality depending on settings many of the movies on sites to show game play etc are very low quality mainly due to bandwidth.
Only wish i could capture my Touch Pro playing 9 as the quality is awesome

Youtube HD playback

I am a new android/captivate buyer. Try as I might (googled for a few hours) I could not find anything on the Captivate and it's Hd playback. My question is:
Is there a way I can play Youtube HD on my Captivate via stream? (and NO I don't mean High Quality I mean straight up HD *720p*.).
I'm just mad the iphone 4 can and I can't find a way to do it on my captivate.
Thanks
Jose

If you are connected via wifi, I believe it defaults to the highest..on 3g it defaults to low and you have to click thne menu button, go to 'More' and go to high quality. Someone will correct me if Im wrong

Neither the iPhone 4 nor any Android phone has 720p screen resolution. If the iPhone 4 is telling you it is displaying at 720p, it is either cropping or compressing the video.
However, the Samsung Captivate and many other Android phones are essentially at 480p HD resolution, which is what setting the videos to High Quality should display (bump it up to 480p playback).

That is the way it works on our version of Youtube. The newer version has a more conveniently placed HQ button and allows you to set HQ as the default.

I might add the Captivate also plays 720p and 1080p (though really it's pointless) video files quite well. And UNLIKE the iPhone 4, you don't have no encode everything in MP4/H.264 to play them. Thank you Samsung for native MKV and AVI container support...
And yes, the Captivate's screen resolution is lower than 720p (assuming a pixel for pixel representation), but in practice if you're watching a movie or tv show, it looks way better if the file is 720p as opposed to 480p.

Man... Why does the iPhone 4's videos look SO much more crisp than my dear Samsung? They can't beat the vividness of the display though Hopefully youtube can be updated to play sharper videos for android later down the line. These screen resolutions are getting more epic every year. Thanks for replying guys.

[TIPS]A/V out of sync when compressing 720p videos

I'm sure you noticed that when you record a 720p/1080p video with a smartphone, the bitrate will be pretty high, in the 10-15Mbps area.
This is not really necessary if you watch the videos just on your smartphone or on a limited size LCD TV, and you can just recompress it using x264 codec at about 2Mbps without severe quality loss (unless it's a sport video).
However you'll notice severe audio video out-of-sync issues if you compress both audio and video tracks and DON'T CHOOSE MP4 (which is the default container for the videos recorded by the smartphone) as default container for your x264 video.
Furthermore, if you want to compress and then JOIN different videos, you have to compress them one by one and THEN join them, otherwise you'll notice glitches in the playback.
I tried with mkv and avi but I kept having sync issues, so I thought that it was worth to share this tip.

SUPER @ video conversion program
Have you tried a video conversion program called SUPER @? Here's its link:
http://www.erightsoft.com/SUPER.html
The program can be pretty intensive in terms of memory used but it usually does a great job for me and bitrates can be chosen for just any vid type you might want to save to. Usually, I turn off my internet connection prior to executing it (so it can't do an update check) and run it by itself.

Yep, I guess it's something similar to Wondershare Video Converter Ultimate, it's just that I prefer more control over encoding parameters (so I tend to use programs such as Avidemux)

You've probably already thought of this but you can load your video in virtualdubmod and have it change framerate so video and audio match perfectly.
No re encoding needed and even on large files it takes less than a minute or two.
If you find virtualdubmod won't recognise the video you can download a suitable vfw codec and it should then.

The problem is that vdubmod won't help, because framerate is not constant and it varies from some 19 to 30fps, at least on Vibrant.
In a lot of cases the fps number gets lost during encoding (and you'll obtain a video which has a constant framerate of 29.97fps), because softwares such as Avidemux doesn't have an option to leave the FPS untouched (or at least it seems that the fps number gets lost if you want to use MKV as container).

I've used it in similar situations so it might be worth a try as it doesn't need a constant framerate, it looks at the audio length then adjusts video framerate to match.
If it is just a problem created while actually recording, ie if the video itself records at varying framerates it would suggest that it can't write to storage quick enough and is dropping frames.
In that case you would need to record in lower resolution or perhaps find a replacement camera application and see if that could fix your problem as sometimes default apps are not all that good.
It also makes a difference if you can close un needed background apps to free ram if low on memory. That can cause frames to drop as well.

Actually it seems that the framerate is lower in case of dark scenes, which seems to be a behaviour found on other phones. I'm writing on the internal storage and I always kill everything before taking a video, so I gotta try another Camera app and see if anything changes.
I'll also take a look at that interesting vdubmod feature, I didn't know it.
Thanks.

Is there a setting where you can change encoding parameters of your x264 on your phone?
On a pc the codec has a feature that can compress more data per frame in darker areas, on a phone I don't know if that is active or not but might be worth checking. Sorry I couldn't help more but hope you find a solution.
