Hello, I shot this video with my 600D and then upscaled it to 4K.



The problem is that I don't have a monitor that supports 4K. All I have is an old 720p LCD TV. So if anybody here has a 4K monitor or TV to check out my video and give me feedback about the quality, that'd be awesome.

Thanks in advance!

edit : original footage was 1152x496 raw.

ok someone said it's not a very good example for a 4K upscale comparison. So I'll try to be back with a more neat video in a few days.

You won't fool anyone with upscaling 1152 pixels to 3840 pixels wide resolution.
It's more then 3x as wide. So 1 pixel becomes 3 pixels wide, for upscaling I suggest to stay within 1 pixel range, so no more then 1.5 times.

1152 x 496 would scale up nicely to 1280 x 550 resolution.

I see. I was just curious about how an extreme upscale like this would look on a 4K monitor. On my 14" monitor when I look at a frame (tiff frame, 3840 pixel wide) I don't see any quality problem. And when I look at it on my TV (which is 720p) it does look good but again it's just 720p.

I wonder if you could see pixels or something if it was seen on a 4K monitor.

I don't have a 4k monitor. But my guess is you don't see seperate pixels, the image just don't look as sharp as it could/should be, for 4k.


eren

yes, makes sense. the raw resolution is too low for a sharp 4K look I guess.

Sky tv I think is broadcast in 720p  which is good enough for most circumstances. So why upscale further.

It would be good for festival purposes maybe? In case your film is chosen and then you could send your movie in 4K. Wouldn't playing it in 4K give better quality on big screen?

Hi eren in your next clip. please try to use a tripod when capturing.
It would be much more convenient to evaluate how sharp your picture is.

Yes, last week a friend also told me the same. I'll be using a tripod for the next trial for sure. Thanks!
