I continue to have rendering problems with Vegas 8c when rendering a large amount of png's on the timeline and Spice transitions. With my latest project I created about 7 nested projects with about 20-80 resized photos (140 x 960) per nested file. I also had a nested m2t veg at about 23 minutes. The m2t 1080 60i render crashed when rendering the master project with the nested files. Render preview RAM was set to 0 and threads at 3.

My workaround was to render indivually each nested file, then create the master project with the rendered nested files, and then render the master file. It was more time consuming to do it this way, but it allowed me flexibility when having to re-render just an individual nested file after a few minor edits. Of course rendering the master project went much quicker.

Does the quality of the completed master project suffer in any way when following this workflow? Thanks.

It depends on what codec you use to render the nested projects because they will be re-rendered for the master output. I would use CineForm and you should not see any appreciable loss in quality. (in fact, Vegas might smart render and just copy source to target) I use this workflow a lot with nested projects that include photo montages.
