Handbrake's x264 performance
Posted: Sun Jan 24, 2016 11:49 pm
Hey all,
After seeing the following post, I decided to see if there was a speed bump between the version of x264 Handbrake is using (r2525) and the latest r2665 (almost a year more of development).
viewtopic.php?f=26&t=32881
My test was done on an Intel i7-5930K @ 4.1GHz.
The video test file was an extra feature clip on the BluRay from the movie "Up" from Pixar.
File: Up_encode_test_2_BLURAY.mt2s
Length: 4 min, 43 sec (6777 frames)
Size: 920MB
I first ran the file three times through the r2525 encoder with the following command:
r2525.exe --crf 20 --preset medium -o 1.mkv Up_encode_test_2_BLURAY.m2ts
Then again three times with r2665:
r2665.exe --crf 20 --preset medium -o 2.mkv Up_encode_test_2_BLURAY.m2ts
Both versions used the same CPU abilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX FMA3 AVX2 LZCNT BMI2
I averaged the first three runs together, then the second three together for the results below (nothing else was active on the computer during this time):
r2525:
FPS: 62.16
Encode bit speed: 3951.56 kb/s
Video size: 133MB
r2665:
FPS: 62.52
Encode bit speed: 3953.15 kb/s
Video size: 133MB
So not very exciting. Now this is no way an extreme through test with features and filters to determine changes throughout the revisions, but a "normal person" test. I take it due to the speed, the file size being the same, and no known bugs towards Handbrake, there is no need to update at the moment!
The devs will update when it needs to be updated...or if they just do to do, for the sake of doing.
Enjoy!
