3gp Movies (converted from DVD) playback problem

[Guest ieubts]

After about 8-10 minutes movie Playback gets "jerky" (unwatchable). These are .3gp files converted from DVD. I've tested two different movies (both about 90 minutes long). The "jerkyness" doesn't seem to get worse, but only the first 8-10 minutes are perfect. The audio is fine. I'm playing the files with the player that came with the phone (mobile version of WMP). The .3gp files won't play with WMP on my PC, but quicktime plays them perfectly (on the PC). Any ideas on a way to fix my problem.....convert to different format.....different player for the phone....? Anyway, the phone is new to me and I'm having a lot of fun with it. I'm fairly experienced with video encoding/conversion and I'm interested in the best way to get dvds on my 2125. Thanks.

I spent quite some time coding movies and probably had the best results using VirtualDub.

This post has the settings that I used.

I found it best to convert the video to 320x240 and then pre-rotate to 240x320. This prevents the phone application having to rotate the video. remember to set TCPMP Orientation to Normal.

The other thing is to code the audio at a lower frequency i.e 32000Hz @ 64K/bits.

On the 2125, you should get great quality with no "jerkyness".

Hope it helps :D

I'm not sure what settings or what you use to convert but mine is called 3GP Converter and it convert any video format into the desired video settings. I use QVGA, 15 fps, stereo audio, normal quality. Any higher you wont notice a difference in quality and it would skip so its actually lower performance. This keeps a movie at around the 300 mb range, give or take 20 mb depending on length.

Thanks for the replies! Installing the TCPMP player on my 2125 seems to have solved the playback issues I was having. I'm using the ACALA free 3GP converter (not many setting options but extremely easy and fast). Anyway the converted movies play very smoothly now with TCPMP.
