h264 more efficient than h265?

Post by Sigma » Sun May 19, 2019 7:32 am

Description of problem or question:
I have an avi file with ~ 144GB.
When I use the lossless setting for h264 in mp4 the filesize is ~285 MB.
When I use the same settings (so lossless) and just change to h265 in mp4 the file now has ~1,54 GB.
I thought that h265 was created to be more efficient. Or is lossless not handled equally in the codecs?

Because the avi file had some mistakes in it, I had to reexport the film (nothing really changes and the file has again ~144 GB) and I used the same settings for h264 in mp4.

HandBrake version (e.g., 1.0.0):
Used version is 1.0.7. I tried 1.2.2 but I get a crash on startup

Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Windows 7

HandBrake Activity Log ***required*** (see How-to get an activity log)
Log file report will follow soon. For some reason Handbrake is closed and I have to redo the encoding.

Log files are saved to disk and should still be there unless you have deleted them.

OK, I didn't know that.
If Handbrake does not delete them by itself after some time, doesn't it become some sort of hoarding problem after you have encoded many videos. This also sounds like it could become a problem for file systems like btrfs with all it's metadata collections.

Handbrake usually deletes logs older than 30 days, but you have to run it in order for that to happen. :)

Since there is no comment in here I question if this post should be moved over to "General Questions" since it's not really a Windows, but an encoder thing

Efficiency of the encoder depends on a lot of things, and means different things to different people.

From reading this and other sites, my impression is that h265's computational complexity is wasted below 1080p, and it gets progressively better as the resolution goes up, so file sizes go down. And that means transmission bit rates go down for the same resolution.

On the other hand, the increased computational complexity, if not reinforced with hardware decoding, can make the receiving end "lag", as it takes longer to decode a frame than the frame is supposed to be displayed for. That's a different kind of efficiency...

For me, I have few videos larger than 1920x1080, and most of the playback hardware doesn't have h265 decoding hardware, so h265 is wasteful for me.

The state of x265 is still evolving compared to the very well optimized and mature x264. It's conceivable it will get better.

Currently, x265 is always better for two scenarios: low bit rate encodes including SD, and 4K. For high quality HD encodes, x264 continues to shine.

This file seems very compressible. If x264 can compress 144 GB to 285 MB with "lossless" (RF 0), I wonder what the file size is if a saner CRF (say 16) is used.

For me it is the filesize for the same (lossless) quality.
Both encoders are set to RF=0 (so lossless). Both have the same starting file (the 144GB avi file, ~7min long, 2560x1440, lossless video, lossless audio), but the h265 file is over 5 times larger than the h264 file. In a second run (same settings, same video file, same Handbrake version) the h264 file was about 675MB which still is over double the size the old h264 has.

The same video encoded with h265 and RF=16 has the size of:
h264 with RF=16: 337 MB
h265 with RF=16: 301MB

So yes, the filesize with h265 is smaller than h264 - but only a little bit more than 10%. Or is 2560x1440 not large enough to really get h265 to work?

By doing a side by side comparison in quality I think there went something wrong with the first h264 file and that the h264 file with 675MB is the better example here.

So in sum again:
codec | RF-0 | RF-16
h264 | 675 MB | 337MB
h265 | 1576 MB | 301 MB

If you want to compare directly it might be better to use x265.exe and x264.exe directly or maybe even just ffmpeg.

If I want to compare the implementation of x264 and x265 directly you would be right.

But I want to know why the files are the way they are if you want to encode a lossless video with both codecs in Handbrake.

With which encoding settings?

The original logs for lossless quality are in the first comment.

For your new encodes:
