@huskereurocat I'm confused. You show in your image that the events you've created with transparent backgrounds, don't have any events on the track below. In this case, there is nothing underneath to show through the transparency, so the background will be black.

Have you tried moving them back on the timeline so that they're directly above the events on track 2?

You have to render to a Codec that supports an alpha channel. Normally these are uncompressed, but a few compressed formats (such as Pro Res) support the alpha.
Also when you import a video with a transparent background (alpha channel), be sure you enable that under file properties.

I tried to render using the Pro Res Codec and even after I enable alpha in the file properties, it still has a black background. Any other suggestions? Pro Res is listed as Apple in Vegas. Is that going to work since I have a Windows machine?

If I move the clips to the timeline and then render that, I get the background of what is on the layer below. In this case, my game footage. There are 17 regular season games and what you saw above is just one of those games. I want the render to be on a transparent background so that the layer below will show through in each game. If not possible, I can just make clips in Photoshop for each render. It's just that having an mp4 to plop on that track is much more convenient than having to create new clips each time I want to render that section of the timeline.

"It's just that having an mp4 to plop on that track is much more convenient than having to create new clips each time I want to render that section of the timeline."

Therein lies the problem. MP4 doesn't support transparency.

I'm trying to render a series of clips with the transparent background that I created in Photoshop.

The transparent generated clips in photoshop are just stills and saved in .png format? Just create a separate Vegasproject with those transparent clips and nest that project into the timeline of your new project. No need to render a video with transparency.

To render with transparency in Vegas Pro, select the 'Video for Windows' format and then the appropriate template. The template can be changed by selecting the Customise Template button and in the Frame Size field of the template window that opens a custom setting or oroject settings can be chosen/coded option. In the Video Format field, select the Uncompressed option and then further down the template window check the 'Render alpha channel' option - then render.

The downside of this approach is that the .avi file created will be huge. It's been a while since I've used an .avi file with transparency, but I seem to recall that when putting the rendered .avi file on the timeline, it is necessary to select Properties for the event, select the Media tab and make a selection in the Alpha Channel field of one of the alpha channel options.

@huskereurocat Hi, Apple ProRes you have to choose Prores XQ

but the file i just produced of a 0.06sec title was 5.95GB

I use MagicYUV, that produces a file of 745mb

It's a paid for product but not expensive

Alternatively, to avoid giant video files with transparency, you also can export to an image(.png) sequence an reimport that image sequence into your Vegasproject for overlay.

As @3POINT said:

Thank you everyone for your input. This was the ticket. I didn't realize that you could import a project file into another project. I thought it had to be rendered. The rendered finish using this method is below.

That will make other clips, that I used to render into videos, much easier to save and import as source material for future projects. 😁

Ofcourse 1000 frames say more than my few words...

I wanted to do the same thing you are doing. So what I did, was anything that I wanted transparent I added a green screen to the back ground then used colour chroma to remove the green screen. Worked pretty good. Although I think I will try the above idea and see how that goes. Hopefully simpler and easier.

Wow, oh wow!

I just tried the above. Importing a project into a project. This is amazing. Glad I read the above comments.

Just for the record I will add that the GV HQX codec also support alpha in AVI.

As I'm new to VP19 , I just tested it. A 10sec 1080 text with shadow clip took 2Gb with prores vs ~14MB with HQX

You lost me now! I have Vegas Pro 18 and I downloaded and installed this codec, but I don't see it as a render option. How do I use this new codec in VP18?
