Vegas Pro 13.0 now opens MPEG-2 elementary streams

Vegas Pro 13.0 opens MPEG-2 elementary streams. Previous versions couldn't open them.

Just pointing this out as it's been on my wishlist for years and it's not mentioned in the release notes.

Nick,

Thanks for that. I've had many occasions where I've needed this, but had to use a muxer to create something Vegas would digest. This will save some time.

Wow! that's a biggy to not announce!!

Also works for AVC elementary streams, at least with a .264 suffix.

With MPEG-2, I renamed an elementary stream as .mpg, .m2v and .mpv. They all open in Vegas. However the Vegas explorer won't list .m2v or .mpv files. The file extension filters should be changed to include these common extensions. However .264 does get listed.

No smart-render though...

Actually it does smart render MPEG-2 (and its video elementary stream stream), assumed media properties and render properties match.

I renamed my video elementary stream file (rendered using a DVDA template) from m2v to mpg and loaded it in to VP 13. I set the project properties as complaint with the file (clicked OK to the prompt at loading the file). I tried to render it out using the same DVDA template, yet it wouldn't smart-render...

What am I missing?

In Vegas Pro 13 there is no need to rename a m2v file (if you've set the Explorer view to "All files"). I just tested rendering with an MPEG template, extracted the video stream via tsMuxeR and re-rendered that video elementary stream (without having renamed the extracted m2v file). Worked without recompression.

Maybe you did not yet select "Render without recompression" at "Options/Preferences/General"?

Yes, I do have "Render without recompression" set in Preferences.
Actually, tried rendering both the m2v as well as mpg (the same file, just renamed). No luck.

I can't get an NTSC DVD elementary stream to smart render either. The source of mine was Cinemcraft Encoder.

However I just rendered an MPEG-2 program stream in Vegas, demuxed it to an elementary stream with tsMuxerR, and then it would smart render. It's very sensitive about settings. Piotr, what was the source of your file?

megabit wrote on 12/9/2014, 11:05 AM

Nick, it was XDCAM EX mxf (downrezzed for DVD).

I mean what file did your m2v file get demuxed from? Was it from a DVD-spec MPEG-2 file that you rendered with the MainConcept MPEG-2 encoder?

megabit wrote on 12/10/2014, 1:54 AM

Yes Nick, it was.

Seems like something must be mismatching in your project settings or render settings. Maybe the field order? You need the little "=" sign next to the render template, but I'm not sure that in itself is a guarantee of smart rendering.

In general I think if you choose exactly the same render template for the 2nd render as you chose for the 1st render then it should smart render.

Thanks Nick.
