If you're using 3 pass encoding you'll need this option for each pass. Add -ofps xx where xx is the desired fps that you want. You'll need to play with this as some settings seemed to actually make my files bigger. I saw somewhere that you should only half the framerate for best results (for dvds it's typically 30 to 15, 24 to 12) and this seemed ok for me. I've been ripping and encoding movies for my Zaurus and have had pretty decent results at really high compression. Another issue I've heard about is the vbr versus cbr mp3 audio...I've been using cbr. I'm also guessing that 128k mp3 is too high for the device...I don't know what processor it has but it can't be too much better then the Zaurus. Try 64 or 32 for the audio, you'll be surprised it isn't as bad as you think for movies and you'll be less likely to get dropped frames.

Yeah - I've tried various settings - one thing that kills me is that if I turn down the bit rate to a lower setting in hopes that its just too much, the frames per second goes up past 30 and I _know_ that's too high... If there's a way to keep the fps down and reduce the bitrate, I'd love to hear it. > Have you been able to produce video that'll play on the thing under > windows?

They do ship some canned videos on the device and here are a few snippets from mplayer's output: VIDEO: [DX50] 352x160 24bpp 25.00 fps 1132.9 kbps (138.3 kbyte/s) ... Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family Selected video codec: [ffodivx] vfm:ffmpeg (FFmpeg MPEG-4) I don't see any other relevant info in the output. > How much you want to bet that's what Archos means by standard? Before I tried encoding in that format, I would have bet a lot!! Unless some other setting is wrong - like the vbitrate - that wasn't it. -john -- John Lavin <jlavin@wayreth.net> http://www.wayreth.net ,''`.
