@admin, thanks for the clarification, and I hope it does help me.

Do you think the vMix team would consider bicubic interpolation as a feature for a later release? Although I think the upcoming fix could help me in some situations, it may not in others, and I wonder if bicubic interpolation could help me. I'm not a master of interpolation by any means, but I know that I've always like the results I've gotten utilizing bicubic interpolation on my images.

@admin, I'll try out that update. Thank you.

Hypothetically speaking. If bicubic could be implemented and applied on a per input basis, I'd be willing to devote 4-16 times more CPU/GPU resources to have one or two scaled inputs look better. (Assuming I can still maintain a stable workflow and it doesn't completely overwhelm the hardware) I'm running a fairly high end rig, and would have no problem burning more CPU/GPU cycles on better scaling quality on the one or two layers I'd need to do that to.

If the 4-16 times more resources has to be applied to all layers across the document and can't be applied on an individual basis, then I could see why it might be impractical to implement as you're then probably talking an orders of magnitude performance hit and system crippling workloads.

Again, thanks for the update and the explanation.

It would really help if you could post some raw image examples and the render results so I can test.
On every image I try in .61 it makes a substantial difference, including 4K to HD

Maybe you can simply zip your files and use a cloud service for download?

Regarding your issue, are you sure there is absolutely no deinterlacing for this source? You said 1080p I checked but some capture card sometimes produce a "fake" progressive signal by dropping 1 frame out of 2. This could also explain the loss of quality you mention...

@admin, I apologize, the update did actually improve the situation. When I tested after the update, I looked at the program out on the right side of the screen and it appeared that the same distortion was still there and I didn't record captures to confirm the actual output. When I captured screenshots of the actual output to get you more examples, I did see an improvement in the appearance of the scaling. It's not perfect, but it's a lot better than it was before the update.

Again, sorry for not testing thoroughly enough after the update.

I threw a couple more scenarios together where I was able to see issues previously, and those scenarios are also improved. I think we're as good we're gonna get as far as this issue is concerned. Things are much better, and anything that's still a problem, I feel like I may be able to make some changes to some of my assets to work around those remaining problems.
