Hi,

How did you edit the sample UVMap? In your image editing software, you have to make sure to work in 16bits-per-channel colour. If you work in, or save it, as an 8bit PNG the results will look nasty.

But also, it seems to me, certain zoom values seem to lead to pixelated results. For example, when using UHD background images in a HD project, the Virtual Sets looked a bit pixelated when the set was shown at exactly 50% of the original size - zooming in a little removed the problem, so I wonder whether the image scaling algorithm used in vMix sometimes encounters values that lead to pixellated results.

I scaled everything up to 8k because I just didnt really know what I was doing and thought that higher resolution would help, it didnt.

The 64 bit depth was my issue, I was editing the sample in photoshop and exporting it as PNG but the export was only 32 bits instead of 64 bits, don't know why. So my solution was to open up the sample UV map file directly in photoshop, do my edits, and just save it (not export) and now the video file looks great. Thank you both for your help!

Thank-you, thank-you, thank-you! This has been driving me crazy for the past week. It would be nice to be able to do a layered approach directly from a Photoshop PSD, but I'll take the solution we have.

thanks for that update Javeer! thats great to know.
