A long time ago, I headed here searching for help trying to create alpha video files on SVP 10.As I succeed, before I went fire-working, I bumped into a problem. A 10 secs .AVI uncompressed alpha video, was 1,2 GB worth! That's really a lot. Well, I patiently waited the IBC 2012 in Amsterdam to ask te Sony crew a solution. They send me :) So here I'm to share my learnings.
Warm Brazilian greetings,
"We did find a way to do it using QuickTime. Follow these steps and see if they work for you:
1) Create a project with transparency. We tested this with a generated text item and with a composite video with chroma-keyed mask.
2) Go to Project > Render As, choose a QuickTime template, and click "Customize settings"
3) Set your Frame Size and Rate to match your project. Then set your Video format to PNG and click Configure. Set your Filter to None and click OK. Then make sure your Compressed Depth is set to 32 bpp color (or possibly more; that's the maximum on my template)
4) Click OK and Render
5) Import the rendered file back into Vegas Pro. Right click the file (either in project media or on the timeline) and choose Properties. From here, you can adjust the Alpha Channel settings.
On my test project, it brought the file size down from a 1.8 GB AVI to a 430 MB MOV, with preserved transparency and no noticeable loss in quality."
this seems indeed. NOT TO BE COMPLEX. But for a non advanced user.It is not complex but also difficult! And believe me; No where on internet is such a article to be found. That's why I decided to published.
Lust but entirely not least: I just finished a multicam project using 4 different shoots. When I tried to apply transition in a take, all others has been affected. In a way that wasn't possible at all to make simple fades like just dragging one into another. Any idea how can I do so, but only for a single take (thumbnail)?

Im not understanding that question too clearly.
But when dragging a transition to a clip, make sure
no other clip on the timeline is selected/highlighted.
And to have automatic crossfade when you overlap the
edges of two clips, go to Options and in the drop down
list, you select Automatic Crossfades, or there is
the icon at the top of Vegas in the toolbar.
