ok, I realize they’re not RAW, but if the folks from Sony call it ‘uncompressed’ that’s good enough for me, and they’re as close to uncompressed as I like to have to deal with (about 200+MB / min) the point is I’d like to get them into a more manageable file size. (and they do seem to be equivalent to Vegas’ “Uncompressed AVI” template…see below)

> Have you tried: Tools | Scripting | Batch Render?

yes, I’ve looked at that script, and the one I have only allows multiple outputs of the same file – I need a single type output (i.e. MPEG) of multiple files. If you know where I can find a script that does that, that would be helpful.

In the mean time, I have been running the solution I have found. It is to use Divx, rather than MPEG in TMPGEnc. It renders quicker and smaller than Mainconcept’s MPEG2, with equivalent quality.

Although it appears to have the same contrast issue on playback as MPEG, when re-imported into Vegas the issue’s not there (UNLIKE MPEG) and in-fact when re-encoded into Vegas’ “uncompressed AVI” (which brings me back to my original filesize as created by the Pyro by the way) I end up with a near duplicate of the original.

Works for me…

Lunchmoney, any soulution yet?

I’m a little late here to the party but had to chime in as I’ve been scratching my head for a couple of days on a VERY similar issue with no real (easy) solution yet.

My problem isn’t directly related to Vegas, but I thought my observations may help narrow the issue down.

I seem to be having the exact opposite problem from lunchmoney

I have a large quantity of analog video captured with an ADS Pyro AV link Pro into uncompressed AVI, and I’m attempting to compress it down to reduce storage space.

I’m using Vegas 6 for editing, but I am using TMPGEnc 2.5 to do my encoding to Mpeg 2 (due to Vegas’ disappointing lack of a batch converter) When using the DVD NTSC settings, I get a resultant LOSS of contrast when I view the file – either in WMP, Power DVD or importing back into Vegas(using Vegas’ built in waveform scope it appears to be about 13-15% loss)using the scope settings of 7.5 IRE setup and Studio RGB both OFF, my once 0% black backgrounds become ~6% gray.

When I use Vegas (and the built-in Mainconcept 2.0 encoder) to encode the file it appears fine. I can’t find any info on the encoder that TMPGEnc uses (I guess propiatary)

I’ve tried tweaking just about everything in the codec with no change – including the buit-in Contrast/brightness filter – nothing will lower the black level back down to where it is in the original.

Sorry this doesn’t directly support your issue but it does demonstrate that there are some re-encoding issues with MPEG that affect contrast levels…now if we could just find out what they are!
