Text Event Lag

Oki wrote on 5/27/2025, 8:00 PM

I did search but couldn't find a relevant post.

Previewing is fine in the best quality, but I notice that when I add text, the preview of that section doesn't play smoothly at all. It will skip thru the animation in a stuttered way and once past the event will return to playing smoothly. My PC is new, very powerful, V22 (build 250) just purchased, all drivers updated, no malware, sfc scannow has been run. Is there something in the preferences I need to check? Other effects don't seen to do this it's only text media.

I just tried this, as suggested by ChatGPT and it works great.

If only the title is choppy during editing but fine in
the final render:Highlight the area in timeline
Press Shift + B to perform a RAM preview render
Or go to Tools > Build Dynamic RAM Preview
This lets Vegas temporarily render it in memory
for smoother playback.

Text in VEGAS isn't that well optimized (esp. if there is animation). Shift b for a temporary preview or shift + m for a lasting one is a good workaround.

@RogerS oh, can you tell me how they differ please? when you say "temporary", how so?

VEGAS does have help that has good descriptions of features like dynamic ram preview and selective pre-render.

The former is saved to ram and overwritten when you play anywhere else in your project. The latter is rendered and saved using a file and persists.
