New H.265 codec on test – ProRes 4444 quality for 1% of the file size

nonlinearpost by Andrew Reid

CineMartin are the first company I know of to give us H.265 HEVC (High Efficiency Video Coding) conversion with the just-announced CINEC v2.7. It supports up to 4K resolution and you can try it today.

In case you live at 12 Under Rock Drive, the H.265 standard is the biggest codec of the decade. It supersedes today’s most common codec for encoding and internet delivery of video (H.264) and makes 4K recording to SD cards possible on DSLRs.

Cinemartin say in their tests a ProRes 4:4:4 video of 590MB was converted to H.265 HEVC with CINEC 2.7 to an output video of 4.9MB with little or no noticeable differences in image quality.

You can see the image samples below (click to enlarge), even at 1:1 I can’t tell a difference -

This low data rate and file size makes all kinds of magic possible, because at the same data rate as the old codec you get a massive leap in image quality and resolution. read more...
