Roger, source is UHD 30fps and proxy is HD720 24fps.
And, yes, I'm on build 122!
So you made a Vegas proxy of your source file and are previewing it at PREVIEW/DRAFT quality after doing an event level crop?

Yes, that's correct as to what I did.

There are 4 UHD source files. I did a crop on another file, and it's okay! So I renamed the bad proxy and I'm rebuilding it now. Perhaps there was some weird setting when the proxy was built??? I'll post when the proxy is built from this 1 hour file.

The bad news is rebuilding the proxy file did not help.
The good news is the reason only 1 out of the 4 source files has this problem is that there is another condition!
The bad file has a media level fx! It's just color adjust, and you don't have to change anything - just have it. You can even unclick and not use it. Delete it, and it works correctly.

So all four of the source files are of the exact same type. The difference is a conflict with a mediaFx. What Fx is it exactly? Color grading panel or something else?

I don't think it matters what the fx is. It does it with just the color corrector, or just levels.

Thanks, with that I can replicate it. It doesn't require any pan/crop or crop at the event level. Just adding media Fx to media with a proxy and viewing the proxy causes this issue.

You're right! I was always zooming in on that file and thought it was both. I'll pass all the along in my open case to support. Thanks so much, Roger!

My pleasure, thanks for the clear steps to make it easy to replicate. Let us know what they say : )

@wilri001 If you add a LUT filter or CGP as a media Fx do you get a crash? While other Fx result in this location shift I'm getting a hard crash with these.

Roger, Sorry, but I don't use LUTs or the color grading tool. No reply to my ticket yet.

My ticket to fix this was closed about a month ago with an automated email. The next build does not fix it. I was totally ignored. Back to using v21.

@wilri001 Why didn't you try 22 build 194?

In the update log for 22 build 194:

Creating a mask in the Pan/Crop tool now works as expected when the Preview window is set to Preview quality 

It was marked as solved in 22 build 194. I'm also able to verify that this problem existed in older versions, but no longer able to find this problem in 22 build 194. As long as you update to the latest version, you won't have this problem again.

If you find that it still exists in the latest version, please report it in detail so that we can help you.

I did try build 194 and it is not fixed.

@wilri001 Could you share exactly how you triggered it? Which media level Fx did you use so we can repeat it?

I did try build 194 and it is not fixed.

@wilri001 Sorry I was wrong. I mistook the present problem for another solved problem. After testing, it's indeed not fixed in 22 build 194...

The way to reproduce this problem is just as mentioned earlier in this thread: create a proxy for high-resolution media and add media FX to it.

I'm applying color correction and then pan/crop this morning. I don't think it matters which fx because I know I tried others 2 months ago when I first discovered the problem. And I just tried a second test, and I just had to apply the color correction and the preview window showed a smaller picture without doing any cropping.

@zzzzzz9125 is it Magix policy to close tickets without fixing the problem? Note that the automated email did not say the problem was fixed. It just said "you opened a ticket and it was closed. How was your experience?". My very unhappy response has been ignored, too. I am a software developer in my "day job" and I'm sure I would be fired by my company for treating customers this way.

@wilri001 I have a similar spec PC as yours. I also edit UHD 4K, but have never used proxy editing. My source footage is from Panasonic. A lot is 422 10bit 150Mb/s. My Preview is mostly Best or Good, Full or Half.

I've used both event Pan/Crop and color grading from the Color Panel. Everything displays as it should. What specifically are you doing with the footage and how?

A couple of questions. What AMD GPU driver are you now using? Can you share via the cloud, a small sample of unedited footage? I'll give it a test. Can you show screen shots of before you work the clip, screenshot of what you are doing in Pan/Crop and your color settings?

@Reyfox  After the following three steps, I'm able to reproduce this bug:

1. Create a video proxy for high-resolution video footage.
2. Adjust the preview level to draft or preview. Only these two preview levels use proxy files.
3. Add any FX to this media (not events!) .

It doesn't seem to be related to a specific GPU, for I'm using NVIDIA RTX 3050.

And I just tried a second test, and I just had to apply the color correction and the preview window showed a smaller picture without doing any cropping.

Thanks for confirming - that's all I needed.

I'll retest proxy files when I get a chance as there were multiple issues last time I checked. I also saw this with my NVIDIA systems.

@zzzzzz9125, I must be missing something. @wilri001 says "Make some event fx. I did a crop of the center of the frame." in the original post (#4). You say add FX to the media (guessing while it is in the Project Media tab)?

I've created a proxy of a 4K file (it is in the same folder as the original file (P1001771.MOV.sfvp0), changed Preview to Preview>Half, drop file on the timeline, adding any effects and it appears correctly.

Adding a Media Effect from with the Project Media tab, it appears correctly in the Preview window (Preview>Half).

Scratching my head.
