4K Video/1080p render? (vids inside)

[George Dean]

This is the last of my sample uploads. It’s the same as #3 in my previous post with the exception this is 4K 2160p (QFHD 3840×2160-23.976p).

Hey George,

Thanks for taking the time to post the renderings.

I had to wait until YouTube finished processing the 4k clips to view them, but it appears you’re having the same issues with the Blinds/Spin transitions in 4k (very grainy and pixlated)

The 1080 clips all look fine

I just updated my GPU drivers and tried again, but I still have the same issue

Hi Rick,

There is some crystallizing effect during the spin of the spin transition, which is a part of the transition effect. You can see it in the preview as well regardless of the resolution 4K or HD. It is more apparent (visible) at 4K because of the higher resolution, but it is also there in HD, just not as visible. Easier to detect if you look at the render frame by frame.

I thought your original issue was with the still, just after the transition going from clean to blocky pixelating, and that is not in the samples I posted, at least I cannot see them in the preview, in either of the 4K or HD renders in any regardless of the codec I used.

If your issue is the crystallizing (call it pixelating perhaps) during the spin, it is on part of the viewing area, not all, which is strange. If we draw a line from the bottom left of the preview area to the upper right, the crystallizing is then on the right side and a little bit towards the left, but not in the upper left portion of the viewing area!

Here is a screen grab of the pixeling in your original 4K Youtube example appearing shortly after the spin, which is what I thought you had an issue with…..

Here is a screen grab of the same frame in my renders, which are clean…..

The crystallizing effect in the 3D Blind Spin transition, during the transition is the part of this transition I don’t like and prefer the NewBlue Flip transition instead, which is much cleaner.

Yes, I meant the crystalizing effect.

Here are a couple of screen shots from what I see in your videos:

It’s definitely more visible in the 4k clip

I barely see it at all in the 1080 clip

Hi Rick,

Here are 3 screen shots from your original 4K video taken in full screen mode……

This is during the spin transition and you can see the crystallizing on the plate and the nose of the car, not so much in the left top of the viewing area. This is present during the preview as well as the render, on my system. As we have stated more visible in 4K than HD. But, because it is in the preview (set Best (full), I would expect it to also be in the render.

This is during the first frame after the spin transition has completed, pretty nice image and what I would expect.

This is 1-2 frames after the transition and after the frame above, the photo gets pixelated. In your opening issue when you spoke about the still quality, this is what I thought you were referring to. This pixelation stays on the still for the remainder of the display time, about 5 seconds until the next transition.

There is none of that pixelation during the display of the stills in any of my examples. I thought that is what you wanted, so I thought I had success, you didn’t, and there was something different between our systems causing us to have different results (I still think this!). However, with that eliminated from my examples, at least, the crystallization in my examples is not satisfactory to you (I don’t like it either). Which is why I like the NewBlue transition which is clean before, during, and after the transition.

However, we probably have other differences, which may be more apparent, causing a slight difference in what we see visually. Although I can produce 4K, I cannot view 4K. Both of my monitors are only HD (1920×1080) resolution. So is my flat screen Sony TV, just 1080p. So, 4K video looks a little better (sometimes) on my monitor, but certainly not what you see if you have 4K displays. We also have different GPU’s which at times can produce different results.

So I am now reviewing what I/we have learned? We see things a bit differently because of the differences in our systems. We both are not pleased with the results of the 3D Blind transition in 4K. You are getting some blocky pixelation after the 3D Blind-Spin transition in your renders, I am not in my renders. I’ll only speak for myself, but I’m pretty sure I am still as confused now as when you started this thread, maybe not, I’m not sure! I still think there is a difference how some of these legacy transitions, which were probably coded for SD and HD resolutions, handle higher 2K and 4K resolution. That is probably why the NewBlue does a better job, it has cleaner coding match.

I think I may enroll in some obscure social science doctorate program, then copy & paste this thread and submit it as my thesis!!! But right now I’m going to down a couple shots of Jack Daniel’s, pop some extra meds, and call my therapist!

Again, thank you for taking the time with all of this.

Where do I find th eNewBlue transitions?

Hi Rick, I sent you an email…..
