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

  1. Is this a known bug in the current build?
  2. Is a fix planned for an upcoming maintenance update?
  3. 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.

Would it be possible to provide a .veg file (I assume the media doesn't matter) for testing? Please upload to a sharing site.

That depends... Who are you?

Someone who helps test VEGAS and reports bugs. Otherwise try VEGAS support and offer the same file.

Sorry, this is my first post here.

I will recreate issue and followup with the results ASAP

Thanks

Excellent, that should help speed up the process of isolating and fixing this issue. Thanks for reporting it.

Sorry for the delay!

I can upload a *.veg, but have now encountered this in more than just 1080x1920 formatted videos.

What I am seeing is when a project's settings are 1080x1920 or even 1080x1350 but the clip differs, the clip needs to be cropped to fit an Output Aspect, say a clip that is 1096x1900 as an example, the pan and crop tool makes the adjustment as it is supposed to, but whether I add some motion via keyfames etc. eventually the clip will jump, and sometimes even jitter.

I found that by restarting the program and clearing caches, this sometimes minimizes the jumps, but not all.

I even tried to render just that clip into the desired format (although doing so deprives me of the latitude of exploring the outside boundaries of that clip for motion), but that render ends up with the jump/jittering anyway.

This only started happening since upgrading to Vegas Pro 23.0 Build 302.

LMK, if you still would like a veg file, and I will try to recreate the issue specifically for this purpose!

Thanks!

p.s. For what it is worth, ChatGPT, when asked to research this issue reported to me that it is a commonly known problem!

This is a well-known issue with 23.
