No Recompress Rendering question

Kazmosis wrote on 7/2/2015, 10:48 AM
I wanted to know if anyone knows a way to enable no re compress rending for MPEG2 dvds captured to vegas. I occasionally capture and edit a dvd and even though I match the project properties perfectly I suspect the bit rate from the captured dvd is fractionally different than what I select. Always results in re compress.
Any advice appreciated.

Match resolution, frame rate, field order, and bitrate exactly. It will work.

I still don't understand why Vegas doesn't simply have a checkbox for "Smart Render", and then it would go find all those values for you. You shouldn't even have to be aware of what they are.

If it can know that what you've entered doesn't match the source, it can know what the source is and fill in the blanks for you. Hmmmph.

I think Sony took a stance early on not to rely on media flags alone for its settings -- perhaps something that should be revisited.

That really doesn't make any sense, since the only way that Vegas can know if it's going to be able to smart render with the settings you've given it is to compare it to the media flags anyway. If it wasn't using the media flags then the best it could possibly do is guess that maybe the user just happened to enter the right values and always (try to) smart render whether they're right or wrong, or guess the user doesn't know and always refuse.

There were a lot of errored flags in 2002.

In earlier versions, wasn't there a button to select "match video properties" for rendering like there is for project properties? Seems like I remember going to render and using the "match' button to select rendering format.

match output settings would only works if media on timeline are all the same. if i use 2 video formats, which it will use?

easier to make a export template that "always works". (if works in the first place of course ;) )

I have now tested Vegas smart rendering with standard definition MPEG2, and concluded that there is some benefit but not as much as might be expected. The results are better than for HDV which I tested before.

OK. Thanks everyone for your helpful insights. Many of the dvd's I rip have fractional value bit rates and I can't seem to match them exactly but will keep trying.

You didn't state exactly the type of editing you want to do with these, but if its fairly simple like doing cuts and joins, transitions and titles, you might want to try something like TMPGEnc MPEG Smart Renderer, VideoReDo or Womble as suggested by Peter Duke at the end of the referenced thread. You'd probably have a better chance of smart-rendering with these tools rather than Vegas. They all have free trials.

Actually the max and average bitrate constraints are relatively forgiving. You can set the min bitrate at anything you want.

Look elsewhere first, such as field order, and of course there can be no cropping, fx, or changes on the timeline.
