HB "dulls" videos

Post by eniwetok » Thu Jul 25, 2019 6:25 pm

Description of problem or question:
I use HB to compress videos shot on my Canon camera. But when comparing screenshots the original always seems more vivid than the compressed version. Note I'm using custom settings... usually 3000k h264 for 720p videos at the "very slow" encoding setting.



Steps to reproduce the problem (If Applicable):
Always happens.



HandBrake version (e.g., 1.0.0):
1.0.7 64bit



Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Windows 10, 64bit Creators Update



HandBrake Activity Log ***required*** (see How-to get an activity log)

Thanks for your description and logs. Will you post screenshots or original examples please?
"Seems more vivid" doesn't give much of a clue...

I wanted to post some screen shots but didn't see that option.

Well, the option is there for me. Good luck.

You could always post them somewhere else then link to them here.

Actually, no you generally can't link to external images as images here, for security reasons. "The powers that be" have posted messages about that several times in the last month or two. You can put a clickable link in for them.

Here are some screen shots

Original https://ibb.co/jfnqrG2

encoded https://ibb.co/yhWTTww

Note the original is a bit brighter... it's as if HB dulls the colors a bit. It's not that noticeable unless one compares the two.

Any explanation... or suggestions, would be appreciated.

3,000 Kbps is (way) insufficient for this video. A CRF equivalent of almost 30 is nowhere near transparent to the source.

3,000 Kbps is (way) insufficient for this video.
In addition to such a low rendered bitrate and your source being top-shelf AVCHD 25, It is also flagged as VUI full-range (yuvj420p), causing Handbrake to produce flatter output levels. If your video was shot a little conservatively, it would cause the result to look "duller" and not as bright as your source, that also being my observation.

Next time out, set your camera exposure 1/3 stop brighter, or until it just starts to show zebras in the viewfinder highlights. See how that looks and make your own decisions accordingly.

I've got some nifty analysis tools and I'll be glad to look at your camera source levels for "best fit" if you'll upload 60 seconds to Dropbox or Drive.

I think many people will agree that RF 20-22 should look a lot better for your 720p footage than 3,000 Kbps CBR.

s/CBR/ABR -- not quite as restrictive.

RF20 produces a file the same size as the original.

All these years I thought 2 pass CBR produced the best quality for any given average bitrate. That's not true?

Yes, but for this particular video you won't get good results at 3,000 Kbps (basically the same results as CRF 30), unless maybe you're willing to denoise it a bit (and/or drop the grain tune).

Canon AVCHD really "loads" the lower bitrates so as to prevent artifacting and shadow noise.
With CRF you can safely unload the low-demand areas, in addition to maintaining motion complexity.
If CRF 20 give the same size, try 22 and see if the quality pleases you. For 720p and x264, I get really nice delivery at around 9-12 Mbps, usually.
