VIDEOS: 3 80 second crops from 3 live action videos; 2 @ 640x480, 1 @ 512*384;
all less than dvd quality with some blocking.
S/W: HB 3496.
Constant Settings: bframes=16trellis=0:ref=2; Constant quality rf=19.
(NOTE! Trellis=2 was used for the subq=10 tests as per handbrake tooltip)
Variable Settings: 8x8dct=0/1; me=dia/hex/umh; subq=0, 2, 3, 4, 5, 6, 10
(NOTE! UMH only used for the subq=10 tests)
I want to convert some videos to perfect copies of size 0kb in 0 seconds of cpu time. Since that's impossible, I've been trying to work out which settings to use that will give me a compromise that I'm happy with. To do this I've generated one base encode and one top encode for each file, then normalized the data so that I can say "These settings will give me 85% max compression and 75% highest quality in 1.4x base time".
NOTE!
=====
I KNOW these results won't hold for every video or even one particular video - the idea is to find some settings that I can be reasonably confident are a good compromise. The only alternative would be to do multiple encodes then check each one - which would defeat the point of minimising cpu time.
I also KNOW that SSIM values are not exact and may not tell the whole story - but unless someone (and his / her friends) wants to rate each (RF=19) video by hand on his/her own, and then justify why their score should be chosen as the final score for each of the 186 encodes... If you can suggest a different metric, I'll look at that.
I'm hoping that some people might find that these results hold for them; but the source material obviously plays a major part. Those who are interested
might want to try running some of the low-cpu suggestions with a short clip from some of their own sources just to see how well - or not! - the results
hold up for them.
Anyway...
=====================================
BASE ENCODE SETTINGS: bframes=16:subq=0:trellis=0:me=dia:8x8dct=0:ref=1
SOURCE : FPS > SSIM > SIZE /bytes
FILE 1 : 91.7 >17.717 >22259606
FILE 2 : 94.3 >18.298 >12676318
FILE 3 : 101.3 >15.632 >22547999
<- Note the variance in SSIM despite the "constant quality" setting.
<Yes, I know it's a rate factor; I'm just pointing it out.>
=====================================
TOP ENCODE SETTINGS: bframes=16:subq=10:trellis=2:me=umh:ref=3
SOURCE : FPS > SSIM > SIZE
FILE 1 : 5.6 > 20.137 > 20124749
-> +2.42db, -9.59%
FILE 2 : 6.91 > 20.218 > 11442790
-> +1.92db, -9.73%
FILE 3 : 5.87 > 17.751 > 18278853
-> +2.12db, -18.93%
=====================================
Anyway...
The encode name follows the format <Reference Frames> <8x8DCT> <Motion Estimation> <SubQ>.
I think that the processed version is more useful, but here's the raw data first.

Results Coming Up...
====================
The processed FPS is easiest to read - if an encode gets a score of 2 then it takes twice as long as the base encode.
For the SSIM and SIZE data I worked out the range between the base and top encodes; and then I worked out what percentage of that range each encode gave.
<Obviously, then, the base encode would score 0, and though not as obviously, the top encode did get 100%.> This was done so that files which were easy to compress / easy to keep at high quality wouldn't overwhelm the others.
Processed Data / Results...
=========================
I've :
(a) left the FPS in their normalized form as it makes it clear roughly how long an encode will take compared to the base encode.
(b) sorted the results by FPS as well.
(c) added a score that tells us how well the encode combines size reduction with ssim quality.
<Basically the score is equal to normalized ssim * normalized file reduction / 100>.
Code: Select all
Encode Name: <FPS, SSIM, SIZE, SCORE>

CONCLUSIONS
============
1 0 Dia 2: <1.43, 52.64, 17.90, 9.426>
<- As expected, 1-0-Dia-2 is quickest, but it doesn't actually do much.
1 1 Dia 3: <1.69, 82.20, 57.05, 46.895>
<- Only 1.7x as CPU intensive as the top encode, yet it gives 82% of the SSIM score.
This is my new setting for live-action encodes that I'm not too bothered about keeping.
1 1 Dia 6: <3.15, 84.02, 78.32, 65.806>
1 1 Hex 6: <3.27, 83.94, 79.03, 66.341>
<- Both give quality and compression close to 3-1-Dia-6 but in roughly 66% of the time.
3 0 Dia 6: <4.10, 67.73, 38.44, 26.036>
3 0 Hex 6: <4.24, 67.76, 40.02, 27.121>
... I won't be using these two in a hurry...
3 1 Dia 6: <4.37, 84.61, 83.28, 70.470>
3 1 Hex 6: <4.41, 84.56, 83.86, 70.907>
<- Note we're still ~15% from the top encode in ssim and size...
But it's taken under a third of the time of a proper top encode to get there...
3 1 UMH 10: 3-1-UMH-10: <15.80,100.00,100.00,100.000>
<- Top scores for the top encode; but it takes almost 16x as long as base!
