Rendering in pieces
Hi,
Can anyone explain to me in basic terms how to render or prerender my video in pieces. I have about 10 songs in my final video and have been having problems with crashes not sure if it is the length of the video but thought I would try this? I have a standard definition hard drive camcorder using a DELL Studio XPS 16 laptop 64 bit 4GB RAM 500GB hard drive 2.53GHZ duo core processor.With My Regards!

The easiest way to render in sections that I have found, is to place Regions around each section that you want to render. Then double-click the top of the timeline for the first region to make it a loop selection. Then render using the “Render loop region only” option. Once that’s complete, highlight the next region in the same way (by making it a loop selection) and render that. Continue until all regions are rendered.

Great! Now when I am done with everything individually how do I “paste it all together?”
With My Regards!

That depends on what format you are rendering to. If it’s a format that Vegas can smart-render then you just place all the rendered videos on the timeline back-to-back and render one last time. Vegas will just copy them all into one file if it’s the same format as the source.

My files are MPEG2 so I assume I render as a MPEG 2? Does Vegas “store ” these rendered pieces in a folder or a “place”? How do I add all the pieces back to the timeline? Where are the rendered pieces located?
With My Regards!

The filenames and path is what you entered each time you pressed render (I do the same: just select with mouse batch of clips and then select next batch and choose loop region only).
If these are MPEG2 HDV files then I believe Sony should be able to smart-render them. Open these files in a new project and match project property settings. Then choose matching HDV output when you render to final file.
If these are not HDV files then it’s tougher. There are several MPEG2 join programs available but don’t have any recent experience with these (see https://forum.videohelp.com/topic265916.html).
Another option would be to output the files to uncompressed AVI if you have enough disk space for the project (about 900GB for 1 hour uncompressed AVI and 450GB for Sony YUV). Then open the AVI files again and render these to final MPEG2 output.

They are standard definition files MPEG2 on a hard drive camcorder. Does that mean it is more complicated?

I can’t recall if Vegas supports smart rendering of MPEG2 SD but I think it only supports HDV and for V9 AVCHD has been added.
If it does support MPEG2 SD smart rendering you should see during rendering the message ‘skipping re-rendering…’ in the output window. If not it’s not smart rendering and this means you lose some quality since it needs to recompress again.If you need best quality then render the parts to uncompressed AVI or increase bit rate significantly (if you don’t have enough disk space for uncompressed AVI).
Another option is to use a program to join the MPEG2 files. That’s potentially more complicated. IIRC I had once an issue with the transition at the join point meaning DVD player could slightly pause where you joined the files (but not sure if that’s always an issue since it’s been a while I’ve done that).

Try it and see. I think Vegas Pro 8 and 9 will smart-render SD MPEG2 if you match the render parameters to the source.
