View Full Version : Good 1080p video-source for encoding-tests?

Hi, I wonder, where can I find a good 1080p video-source for doing encoding-tests?
"Benwaggoner HEVC encoding challenge" linked video-sources to test encoders, but those video-sources are quite big and are not video-clips of totally different contents, SolLevante_SDRv2_1080p24_8bit.y4m is only 2D-animated content. But if there are no better alternatives than them, then I'll use them.

Also, what are the main things to watch for when doing video-encoder-comparisons? The things to look for that I can think of now are: general video-quality, quality dark scenes, low banding, low blocking, low aliasing, not all (non-noise)grain lost, picture-quality of hair.

Should I encode at the same bitrate that I plan to encode my real encodes (which is quite high bitrate, normally around CRF 18), or is it OK to use a lower bitrate to easier distinguish the video-quality of the encodes?

Thanks.

FranceBB posted a Sky advert sample clip (Source.mxf) which is no longer available (~300MB, 40secs)
Perhaps he could be persuaded to upload it again (he likes it if you call him 'Sir').
[You might also wanna say that MediaFire links don't expire, and don't tell him I sent you, he dont like me]

I wish, but I don't own land, so I can't be called Sir :(
I also haven't finished my PhD yet, so I can't be called "Doctor" either.
Best I can do is "engineer", I guess ehehehehehehe

By the way, I used to have free high quality public samples for users to test (https://youtu.be/2gp-LuB49Wk), but I lost them and the ones I kept I can't share for rights-realted reason... :(

ASC StEM2 - Standard Evaluation Material 2 (https://dpel.aswf.io/asc-stem2/ ) might be interesting.
