re-encoding x264 from high-def. profile to iPod (Baseline)

[chipzoller]

I've tried re-encoding high-def. profiled x264 encodes for my iPod using megui profiles but none will play back. Is it just not theoretically or practically possible to do this? I can't think of how I could be messing this up but... Has anyone else had the need to re-encode from a higher profile to a lower one? Went from HQ-Slow -> PD-iPod

Shouldn't matter what profiles. You can open the avisynth script megui generates in the preview window or other applications, right? That should be the only requirement to generating a proper avc file.

Actually, will they not play play back on PC or just the ipod? I know older ipod versions require specific atoms and maybe other hacks, and specific maximum dimensions.

The re-encoded files play fine on the PC, just iTunes and thus the iPod will not accept them. And yes, the preview window displays the video just fine. I thought this might have something to do with the video complexity created by the high profile not getting "down-graded" to the lowly iPod specs. I can't think of what else it may be; clearly it's the video stream because even muxed with audio it won't copy over.

EDIT: I also tried just loading the source with directshowsource() but not specifying any frame rate...I thought that might have had something to do with it, but alas it makes no difference. Foxyshadis, any ideas?
