    I have got a Panasonic SD20 camcorder that records in avchd with 5.1 audio, i have imported this onto my pc and edited in Vegas Pro9.0a and have exported as m2ts using sony codec to 1920x1080 and 5.1 audio with all the settings the same as the source file.

    I then copy this to the PS3 for playback which is fine but when i fast forward or rewind it all goes out of sync and the video plays too fast or too slow (jerky), I cant then get it back on track.

    I wondered if there is a better option to export from Vegas or a more widely accepted codec/profile etc? or is there an option im not using that may correct this? or can i use a tool to make it readable?

    I tried exporting as mp4 which worked better but lost the 5.1 audio.

    This is the info for one of the files in media info

    This is also a readout from the file when imported into tsmuxer.. I tried demuxing and remuxing but didnt really know what i was doing but it didnt improve the situation much anyway.

    MUXOPT --no-pcr-on-video-pid --new-audio-pes --vbr --vbv-len=500

    A_AC3, "C:\Users\Craig Simpson\Desktop\Florida 2009\1. Intro.m2ts", timeshift=-39ms, track=4352

    Please help I have spent hours and hours and days on this trying different things. I thought it would have been simple export from vegas and play but it doesnt seem that simple.

    Im not sure if this is the right forum for it but it covers about 3 and thought this might be the best but if it needs moving then feel free.

    I have tried a few more things to narrow down the problem, I have copied some of the original MTS files straight from my camcorder to the PS3 HDD and it plays perfectly, I am pretty sure it is something that is happening when exporting from Vegas but I dont have a clue what it is.

    Are there any other formats I can try?

    I compared the original file and an exported one in vegas and the only differences I can see are that the original audio was 384kbps and the exported version was 448kbps both 6 channel. the original video was 13mbps bitrate with video, format settings, ReFrames was set to 4 and the exported was set to 2 ReFrames and 16mbps but i dont have a clue what the reframes setting is.

    Please Help.

    Its worse than I thought, the first files I exported from Vegas lose sync and play weirdly after a few minutes of continuopus play. i thought it was just the fast forward and rewind that caused it but it does it just when playing.

    I really cant believe how many problems I am having with this.

    It sounds like you are having an encoding issue, it's the settings when you export from Vegas.

    Here's some stuff that I can recommend, not guaranteed to help you but they might.

    Reduce the video bitrate (Variable ~5000 is more than enough)
    Try MainConcept AVC instead of Sony AVC
    Make sure *YOU DO NOT APPLY ANY DEINTERLACING FILTER*. According to the specs you've listed in your original post you are using PAL video, choose Progressive Scan, stay away from any other filter.

    One last thing,

    You don't have to lose the 5.1 audio when you export as MP4. There's a workaround. Here's the steps:

    Download TSRemux, open your original (unedited) m2ts file, choose the audio track, select demux, set the output paths and hit start, you will have a seperated AC3 file (5.1)

    Render/Export as MP4 (Use MainConcept AVC instead of Sony), do not include audio. Once the export is complete use MKVMerge to merge mp4 with AC3 sound into the MKV container. Finally use the tool called mkv2vob to make it playable in PS3, sounds tricky but it's not. You can find a lot of sources/guides on this on the web.

    Surely it shouldnt be that difficult, should it?

    I would think if software edits avchd with ac3 5.1 it must be able to output it somehow. I have managed to do something with it but cant test it fully.

    I have tried exporting from vegas as uncompressed avi and then encoding using procoder to aac 5.1 (it doesnt give me the option of ac3 i only get aac or mpeg 1 layer 2) not really sure what that means but this seems to work OK but I have no way of decoding aac 5.1 so on my ps3 it show up as stereo.

    Any ideas?

    Hi simoupnorth,

    First of all, Verminaard -thanks so much for making clear the technique of demuxing a source stream, remuxing it to MKV then using mkv2vob. I have a question for you in just one second!

    So, simoupnorth I am in a similar boat to you about converting my files over and I am new to a lot of the intricacies of transcoding. However, I am a bit of a gear head so I went ahead and wrote a Windows batch file to automate almost the entire process. I was inspired by this ffmpeg snippet I found here: http://ps3wiki.qj.net/index.php/Using_ffmpeg_to_transcode_video_for_the_PS3

    You just have to download the latest ffmpeg (pre-compile binaries), the latest mkvmerge and the latest mkv2vob. With that being said you can use this below script in the format of convert.bat filename.

    **NB: I will create a new script that will simply find all the files in a certain folder with a certain suffix (ie. .vob, .mpg, etc) but I am not quite there yet. It won't take me long at all once I can figure out the answer to my question for Verminaard!

    Verminaard, mkv2vob is great -my script along with that program takes my raw VOBs and converts them to mpgs for PS3 (and media player!) just great.

    However, is there a command-line tool that I can use instead of mkv2vob? I am ALMOST at the point of fire-and-forget with this script but I can't find anything on the net that gives a command-line that says "Here is how you demux an MKV and remux it into something pretty for PS3".

    I know mkv2vob uses ffmpeg, mencoder, etc to do its dirty work but I cant find out which of those tools it is using and which args for those tools it is using. I tried using:


    ffmpeg -i original.mkv -acodec copy -vcodec copy -f mt2s output.mpg
    And that gives me the following error:

    [NULL @ 0x1782ed0]error, non monotone timestamps 6030 >= 1530
    av_interleaved_write_frame(): Error while opening file
    I know muxing isn't ffmpeg's strong-suit. Do you have anything with a command-line example that would get me over this last hurdle? Thanks again for your help.

    Here is my batch file for Windows (this assumes that ffmpeg and mkvmerge are properly set in your system PATH statement.

    Code:
