Very interesting codec shootout - MustRead

Man, this is not so good. I just looked again at my .png frame grabs of the 4K frame grabs comparing renders between:

Photo-JPEG
Miraizon ProRes 422
Miraizon ProRes 422HQ
Miraizon ProRes 4444XQ

And I really believe that it's a waste of money.

Damn.

The whole point of higher resolutions is not to fill a larger screen with blurry globs. It is to provide higher RESOLUTION! THat is, to RESOLVE finer details.

I sent these frame grabs to the guy at Miraizon. He contends that he looked at them closely. He also says he cannot see any difference, and quoth thusly: " I looked carefully at the images you sent, comparing the original file "crop" and the ProRes "crop" images. I could not see any obvious loss of detail in the ProRes images over the original. I see compression artifacts in various places in the original image and those are replicated in the ProRes images also."

This person, I'm sorry to say either:

Is lying

Send me a pmessage with your email address if you want to compare these for yourself.

I'm so freaking annoyed.

Again, if you are out to eliminate banding, just render a PJPEG with a light blur mask over the area you're having problem with, and you will have far better results.

Maybe this is why we are not hearing anything from P5 about downsizing? SS and RS has figured it out. P5 says they will use ProRes so maybe they know something they are not telling us. Would be nice if they looked close at received ProRes and give us a better idea on what they think or are planning. This way we can better meet their upgraded video standards.

Thanks Don, I was forgetting to mention that it seems to me regarding the auto downsizing issue is that the HD would suffer, however slightly, from being rendered from the rendered 4K, whereas the benefit of doing our own dual-render is that the HD version is without the generation loss and garbled compression scheme doing it automatically would have to incur.

Agree but will P5 eventually delete all HD versions of 4K uploads? This would leave like you said a re-render of a 4K render as the only option.

Unknown, but I'll not worry yet. Take for instance Motion_Poland's incredible work uploading HD and SD versions of almost every clip. He did the work...and it seems he is quite successful, and as far as I know, he continues to sell both. I'd hate to think of doing THREE versions of every clip though.
