320x240 @ 30fps with no glitches
Please Login to Remove!
Hello,
I've been experimenting with settings to attempt to get 320x240 fullscreen at 30fps with no glitches on a Curve 8310.
Currently I'm using MediaCoder (a free video transcoder) to output MPEG4 in .MP4 and been trying these:
320x240 @ 250k video, 64k mp3 44.1Khz
320x240 @ 400k video, 64k mp3 44.1Khz
320x240 @ 400k video, 48k mp3 22Khz
I found that only the latter, 320x240 @ 400k, 48k mp3 22khz plays nearly flawlessly. Apparently, it seems like that extra sound quality has a bigger impact on BlackBerry video playback than doubling the bitrate.
There are other threads that cover this, but I would like to hear more recent user experiences AND 30fps feedback (not 24fps) with the latest transcoder software -- what settings have you done to get 320x240 video fullscreen playback flawlessly at 30fps? For home videos, etc. (30fps rather than 24fps)

MPEG4 format in MP4 container is what I did. I also configured framerate to match the video (29.97fps), and I also configured the audio to be converted to a lower bitrate. I still get a few glitches (one small jump every 1 minute)
Setting to 200 kilobits per second video and 32 kilobits per second 22Khz MP3 may work better, although 250 kilobits per second with 48 kilobits per second is a good compromise. Depends on what audio and video fidelity you need...

hmm it might be different with the Pearl then. I am doing another encode now, and will update when it's done.
[UPDATE]
I just finished encoding, and transferring the file... It starts to load, then it shows an error.....

This is the wrong thread unless you have a Curve and you need 320x240 30fps video. If you're encoding a movie or for Pearl (instead of a home video on Curve), I can't help... I think older Pearl's support different video formats and need a different resolution.
My MediaCoder settings for encoding my home videos on a Curve (running OS 4.2) is now as follows:
VIDEO TAB
Mode: Bitrate Based
Kbps: 400 Kbps
Format: MPEG4
Container: MP4
PICTURE TAB
Resize -> 320x240
Frame Rate -> 29.970 (or same as source if 30fps)
AUDIO TAB
Encoder -> FAAC
Resample -> 22050 Hz
FAAC TAB
Average Bitrate Mode
Kbps -> 64
MPEG Version -> MPEG4
Object Type -> Low Complexity

I just converted the movie "Mr. & Mrs. Smith" from DVD to a mp4 at 320x240 resolution. Everything works great on my 8310 Curve. The only problem I have is that the picture looks squished horizontally. Is there some way to adjust the aspect ratio? I used DVDfab to convert it.
