Pan/Crop Keyframe Jump Bug in 1080×1920 Projects — Confirmed Across Multiple Clips (VEGAS Pro 23 - Build 302)
Hello,
I’m encountering what appears to be a repeatable Pan/Crop animation bug in VEGAS Pro 23, but only when editing in a 1080×1920 (vertical) project resolution. I would like to confirm whether this is a known issue and if there is a planned fix in an upcoming build.
Symptoms
When adding Pan/Crop keyframes (even simple two-keyframe zooms), the event will sometimes jump or shift position unexpectedly during playback.
The issue persists even with:
Standard 1080p video clips (no 4K, no oversized images)
No additional FX applied
Linear, smooth, or fast keyframe types
Replacing the media does not fix the issue; copying/pasting attributes brings the glitch back immediately.
What I’ve Tested
Replacing the clip with fresh media → issue returns when Pan/Crop is re-applied
Removing middle keyframes reduces the chance but does not eliminate it
Using Nested Timelines does prevent the glitch
Switching the project temporarily to 1080×1350, performing Pan/Crop work there, then switching back to 1080×1920 also prevents the glitch
The same Pan/Crop animation performs normally in 1080×1350 and 1920×1080 projects
My Environment
VEGAS Pro 23 (latest build as of this post)
Windows 10/11
Editing vertical video only (1080×1920)
Questions
- Is this a known bug in the current build?
- Is a fix planned for an upcoming maintenance update?
- Is there an official recommended workaround beyond Nested Timelines or switching project resolution temporarily?
Thank you — I can provide a screen recording or project file if needed.
