Rendering mpeg without encoding =====>HELP!

Quarterbeerz wrote on 12/30/2001, 9:51 PM

I bought a new capture device. It encodes directly to mpeg2 704x480. Capture quality is great! It came bundled with ULead MediaStudio Pro 6.5.

With MediaStudio, it can render my captured mpeg2's without re-encoding them, thus no loss of quality!

Does anyone know how to accomplish this in Vegas 3.0?

I use the ADS Instant DVD.

Captured file is mpeg2 Field B 24 bit 704x480 variable bit rate.

Thanks in advance for any help.

My guess is that it's not possible. Vegas works internally with the AVI
format. Any video clip you render will get converted to AVI before being
encoded in the final output format.

Ouch!

So when I put mpeg2 video clips on the time line, it converts them to avi?

Or when I render it converts them to avi, then encodes them?

I've found that in MediaStudio, as long as my ouput mpeg2 is the same as my original mpeg, no encoding is done. I hoped there was a way to accomplish this with Vegas.

Anyway, thanks for the input.

Any other ideas, anyone.

I'm not sure of the exact technical details, but as you view a video file
on the timeline, Vegas uncompresses it frame by frame to show the
preview. So the file isn't converted into an .avi file on your drive. When
you render, the uncompressed version of each frame is used when
recompressing back to MPEG.

Ideally, you should be using .avi for your source files anyway. MPEG is
a very poor format to use as a source.

Ya, I wish I knew that before I bought my ADS Instant DVD.

I guess I'm stuck using MediaStudio.

Thanks for the help.
