rendering after render

hello,

say I have a project edited that is around 59:00 long and I wanted to adjust something in the edit at around 29:00 - 29:40 and I have already rendered it as an MPEG 2. How do I rerender just that :40 in the middle without having to rerender the entire project? Can this be done?

thanks

You do not want to re-render an MPG2 file. It will look bad.

If you still have the source material, pick a point where you want to start your render. Place the cursor there. Press letter "I" (in). Pick where you want to end your render. Place the cursor there. Press letter "O" (out).

Render as whatever, be sure the select "Render loop region only."

Done.

ok. so would I be basically getting rid of the :40 "donut hole" and replacing it with the new :40 section? if I do, do I just cut that out of the original MPEG 2? I have the .veg file in tact.

thanks

The best way is to render the entire project to a new MPEG file. Vegas has no way of replacing part of an MPEG file with part of another, or even joining together MPEG files.

There is a tool called Womble that can do this. Using that you'd be able to split the original file into three parts, then combine parts 1 and 3 with a newly rendered part 2 from Vegas.

thanks. that's what I was wondering. I'm OK anyway for this project, as it was nit picky and not worth another 2 hour render.

thank you

Do you realize how many hundreds, thousand, millions, or perhaps even more computer hours could be saved if we could all simply select the one small portion of a project that needs to be re-rendered, have Vegas re-render that, and then ALSO have Vegas do a lossless "join" operation with the already-rendered MPEG-2 that preceded and went after the re-rendered section? This is technically completely feasible and would be a HUGE time-saver. Is there ANY user who renders to MPEG-2 that wouldn't use this feature? Does anyone read these forums and truly understand what is going on out here in the real world?
