[Request] Any uncompressed (or not overly compressed) 4k video to test out my tv

Blender Foundation movies are good for testing playback as they are available in many resolutions and formats for free download.

Here's Tears of Steel, which has 4k downloads. Not on mega though. https://mango.blender.org/download/

youtube has some videos in 4k you could try downloading those.

Youtube 4K is still compressed right?

Correct.

Check out some of these, not mega though - UHD Demo

Those promo GoPro videos are very impressive. Just head over to GoPro's YouTube channel.

Hi. I've got a 40" tv and I think that 4K would just be overkill on it. I can see pixilization being an issue on larger screens, though - like if you got a 70" or something. How big is your screen? I'm just curious, you're the first person I've ever talked to who went for the 4K thing.

I think part of the push for 4K tvs is that it makes the bandwidth required for piracy too huge and visible. If you look at that "Tears of Steel" movie - it's 12 minutes long. If you want to download it in 1080, it's about 700 mb. If you want to download it in full 4K, it's 14 GB, twenty times the file size as high def video is now.

Yeah you're right, 4K in a 40" is might be a little overkill. I have a 55" samsung, but I can still tell the difference between 1080p and 4K youtube videos on the TV. But not sure if that's because the way YouTube processes 1080p differently from 4K (4K YouTube videos would tend to have a much higher bitrate). So that's pretty much why I want to test the TV to see if I can see any serious differences from 1080p to 4K.

I think they're addressing the bandwidth problem with HEVC/x265 codec, which seems to have a great potential to compress the video while maintaining the video quality. But now the codec is in its preliminary stages, so I do hope it becomes widely adopted in 4K videos when it matures.
