HDV M2T not bluray compatible

[FrontierDK]

H there

Being a somewhat newbie, here's a newbie question: I have some M2T files from my Sony HDR-HC9e video camera. If I use them in Sony Vegas 11, I'm able to edit them and export them again - without any loss, as long as I use 1440x1080 50i 25Mbit/sec video.

However, if I try to use the very same file in Sony DVD architect 5.2, I'm told that it needs to convert my 1440x1080 50i 25Mbit/sec video to...1440x1080 50i 25Mbit/sec video (exact same). Only if I render as program stream, bluray compatible in Vegas, will DVD architect accept the file and use it without re-encoding it. But rendering it in Vegas is a re-encode in it self.

So...how do I do a loss-less conversion from M2T HDV files to a program stream? It seems crazy that one needs to re-encode MPEG to the same resolution, bitrate etc...with lossy re-encoding

Yeah, Sony at work here,
Some BD players , mostly new ones will play m2t files as they are,

TsMuxer will make BDMV structure , no menu though, you use video stream only with no recompression and make new AC3 stream for it.

Not sure if multiAVCHD can load m2t and make BD with no recompression.

Funny thing, BD specifications now accepts mpeg2 1440x1080 , they changed specifications some year back! But DVD Architect will want to recompress those m2t anyway. What you can do is try to change m2t to mpg wrapper somewhere, but I doubt it will help.

I was in your situation exactly 3 years back and decided to skip this BD player nuisance at all, I have bunch of media players (such as WDTV Live, Popcorn ...) those will play those m2t files just fine.

i believe it is the audio that is not blu-ray compatible. mpeg-2 audio is not allowed.

Right,
only LPCM, Dolby Digital (AC3) and other advanced "for movie" variations (DTS, True HD ...)

But even if you demux to elementary streams, importing video m2v only, DVDA won't accept it using blu-ray 1440x1080i50 template . Other authoring programs like Encore will without transcoding


Even if you re-wrap into mpeg-ps (eg. using ffmpeg), DVDA still won't accept without transcoding
