[mdwright1032]

I am expecting my unit next week. I have a bunch of mp4 movies that i downloaded off of youtube. Will these work or does the cowon have trouble with mp4?

1. I used the search and nothing

2. That did not answer my question. It's related to a different mpeg version. I

Cowon says in their description mp4 player but on the video code's supported it does not list mp4. Which one is it?

[deadohiosky]

short answer: probably not.

longer answer: it depends.

the J3 only supports a specific kind of h.264 profile. the baseline profile. you can read about this here

but the common youtube video will probably use another profile, so no, you would need to re-convert it.

The documentation tells only AVI container not MP4, for the video the codecs are from the MPEG4-ASP family (xvid, Divx, mpeg4), not H264, and finally support for AAC audio seems unofficial and not complete. This blogger says he succeed with some mp4 files, but if you read comments they seem to be ASP not AVC encoded videos.
When you'll get your device, please try AVC-H264 codec (baseline profile) with AAC audio on MP4 container and tell us if it plays. I haven't find an extensive post on which video combinations work or not.
I do not believe AVC-AAC-MP4 video will work, because to support AVC you must pay a licence. You will not silently implement AVC to face a patent suit in the end. So if AVC was on board they would have publicize this feature.

[Edit] You can use SD 320x180px video files from the CNET.com video podcasts. They are valid AVC/H.264 baseline+AAC MP4 files. They play well on a Sony Walkman for example and I think are good to test your player abilities.

CNET MP4s do play on the J3, I just tried.

I've already posted my findings earlier and now only confirm that one can use the tipard video converter to convert video files to mp4 (h264/mpeg-4 AVC Video) for j3.

CNET video as linked by Dfkt working fine but videos encoded for Fuze+ are stuttering (if that is correct word).Though .mp4(aac+avc,320X240) videos working flawlessly on Fuze+.
