Vegas Pro 21.0 - Render Fracture

HaydenLMartin wrote on 6/21/2025, 8:18 AM

Hi everyone, I hope someone here can help me with this problem. I'm a seasoned user of Vegas 21 (Build 208) and I've never come across it before. I'm attempting to render a collection of PNG's that have been animated to an .AVI file format, however this problem seems to persist regardless of what format I render to.
This is a still frame of what the render should look like:



However what seems to be happening is that the render will take whatever point on my timeline my cursor is currently set to and fracture it in a paused state in the render. Once the render is done, the preview in software will be stuck on a freeze frame of that portion of the video. Doesn't crash or anything like that. But this is the result of the render:

Occasionaly the renderd file flickers, but mostly it just shows this visual. I've tried rendering other projects and they all come out fine. If anyone can help me figure this out, I'd greatly appreciate it.

Instead of importing an AVI created from the png's, import the png's directly into Vegas as an image sequence.

I'm not importing as an AVI, I'm rendering as an AVI. I'm only importing static PNG files.

Who's using AVI for final export?

I am? I need an alpha channel. But regardless of the format I render this project to, it still fractures and ends up unusable.

Png's normally have already alpha channel. I understand that you want to reuse the AVI for further editing, try Prores with alpha channel instead. What are your project settings and resolution of the Png's?

Rendering to ProRes with Alpha results in the same problem.

My Project Settings are set to 1920 x 1080 at a Double NTSC Frame Rate.

Most of the PNG files are at a resolution of 1200x480.

@HaydenLMartin

As a diagnostic procedure:

If you make the project and media available on a cloud share (Google drive, OneDrive, etc.) and share the link publicly or privately, others can test on different platforms to crowd source a solution.

@HaydenLMartin said: "Most of the PNG files are at a resolution of 1200x480."

Is there a special reason that all of the .png files are not the same pixel dimensions, at least within a group that's imported as a unique media event?

It's not a group? It's 22 seperate imported PNG images.

I'll post a google drive link to the project and the assets it uses in a moment.
