MKV to PS3 Sync Issue

[Jeremy_bk]

I'm attempting to convert some anime episodes I've got in the .MKV format to a format that is playable on my PS3. The files each have H264 video and 6 channel AAC audio. I've done some research and came across a few different guides on how to do this and have ran into the same issue with all of them. I've tried converting them to .MP4 by extracting the video and audio out of the .MKV and putting them into an .MP4 container with Yamb. I've also tried using txMuxer to create a .M2TS version. With both of these methods I end up with a file that had audio that is out of sync with the video. I have made sure to set the proper video framerate and still the audio is out of sync. I have included the output of both MKVinfo and Media Info in hopes that someone can tell me what I'm doing wrong. Any help with my problem would be great. Thanks

jeremy try gotsent just load the mkv file in and click run. then burn the file to a dvd

Have you actually tried to re-encode or are you simply trying to demux and mux back into another format i.e., from MKV to MP4 or M2TS etc.?

Based on the specs the video will definitely have to be re-encoded because as it is now it is not compatible with the PS3 and simply trying to force a header change from Level 5.1 to Level 4.1 will not work. There are simply too many reference frames. As for the audio it may or may not be OK as it is now. I would argue that AAC LC is a better more safe choice than AAC HE but when I first started doing MP4 conversions I did one with AAC HE that was 5.1 and it worked *shrugs* although I've always read that AAC LC should be used. So the audio may be A-OK and I would try to re-encode the video and mux it with the original audio. If that doesn't work you can always demux and re-do the audio then mux the new audio with the video.

Have you actually experienced the sync issue on the PS3 or only on your computer?

- John "FulciLives" Coleman

P.S.
I just realized that the audio says it is LC and HE which of course is impossible but I am thinking that it is LC if I am reading the MediaInfo output "correctly". So the audio should be A-OK without the need to re-encode it. The video you WILL need to re-encode. I use XVID4PSP myself for such things. Another option would be MeGui.

I was actually just trying to mux the video into MP4 or M2TS without re-encoding but if it is needed that's fine. I've actually not even tried the videos on my PS3. I've been playing them on my PC with VLC and that's where I'm seeing the sync issue. I'll try it on the PS3 and see if I get different results. I'll also try re-encoding it and Gotsend and see if I can get it to work that way. Thank you both for helping me with this!

[Jeremy_bk]

I went back and tried the videos on my PS3. The .m2ts file wouldn't play at all. PS3 said it was an unsupported format but the MP4 did play. The video looked to be fine and you could hear audio but it was like the audio had been slowed way down. It actually sounded pretty funny. I guess I do need to re-encode at least the audio but i'm not sure what would be the best program to do so.

[t0nee1]

As Fulcilives stated,
"Based on the specs the video will definitely have to be re-encoded because as it is now it is not compatible with the PS3 and simply trying to force a header change from Level 5.1 to Level 4.1 will not work."

When using tsmuxer,did you change level to 4.1 ? sometimes it works...
Also in order for the PS3 to accept a .m2ts file,you'll have to change the extension to .mpg or .vob....

[FulciLives]

I'm surprised the video played at all on the PS3 because based on the specs it really shouldn't. So the video playing fine but the audio NOT playing fine is a bit odd to say the least.

As for the audio ... since it is 5.1 AAC I would convert it to 5.1 AC-3 and then mux into an M2TS with tsMuxeR which will allow you to change the header from Level 5.1 to Level 4.1 and with AC-3 audio that should work.

The PS3 will play a file with M2TS as the file extension if you are playing it directly (from a data CD or data DVD or USB thumb drive etc.) but if you are streaming it then SOME streaming software requires you to change the file extension to something else like t0nee1 said. This isn't the fault of the PS3 but of the streaming software. I use MediaTomb for Linux as my streaming software and have no such issues.

As for 5.1 AAC to 5.1 AC-3 ... I'm not sure how to do that exactly. I did once make a MP4 with 5.1 AAC but I don't have it anymore nor do I have any files right now with 5.1 AAC but I seem to recall that I had to do that type of conversion once and I want to say (my memory is foggy here) that XVID4PSP couldn't handle it. I think I had to use GraphEdit to do it and it was a royal PITA process.

I guess I would put XVID4PSP into "AUDIO ONLY" mode then try to load the 5.1 AAC and see if it recognizes it as 5.1 by going into that AUDIO ---> EDITING OPTIONS screen.

- John "FulciLives" Coleman

P.S.
The M2TS file format must have AC-3 audio. I think DTS may also be supported (not 100% on that) but I know it doesn't support like MP3 or AAC etc.
