help with batman converter

I have no idea about ac3 audio, but i believe the M6 only supports MP3 audio in videos.

As for the issues in this thread, i'll post a few interesting things.

I have no idea of the options BatMan provides, i only know it's a front-end for mencoder. I've been using VirtualDub to pre-process my videos since i had a player that only supported AMV video format (Actions chipset, slow and buggy :P). So i thought "i have the XviD encoder, why don't i use VirtualDub directly for my M6 video conversions?" And that's what i do.

Indeed, i got "skipping" frames in the end video when using frame rate conversion, so i decided to try something else. The method i use should work on any converter, not just VirtualDub.

It's as simple as this: Do you need 20FPS on a portable player? Most likely answer is no. Converting to a lower framerate will save space too. As most simple conversion algorithms drop frames when you decrease the framerate, resulting in "skipping", the best way to avoid this is halving the original framerate. Say your video is at 30FPS, then you should convert to 15FPS. If it is at 24FPS, convert to 12FPS. Splitting the video framerate in half ensures that no skipping will occur, and believe me, 15FPS still looks smooth enough on the M6. If it seems too choppy to you and you're using VirtualDub, add a Temporal Smoother filter set to 3 to blend adjacent frames together so the motion looks smoother.

One more thing. The M6 stutters on non-integer framerates, so if you have say 23.970FPS, you should convert to 12FPS, don't let the converter split the framerate in half automatically, specify the value yourself.

Hope this helps, and maybe we can find a filter that decreases framerate smoothly without needing such things as splitting it in half.

EDIT: Avisynth's framerate conversion option gives pretty good results, i'll post a guide later once i test it thoroughly.

How do i know how many fps a video has?

sorry for being a noob:P

Don't worry, we all were noobs once. :P

I use Media Player Classic as my video player, in it go to File -> Properties -> Details and it tells me the resolution, framerate and audio rate of the video. I know of no other way to find this info out coz i never needed any other. VirtualDub can tell you the frame rate too, open your video in VirtualDub, go to Video -> Framerate, and the first info in the window is the video frame rate.
