Another "why is h265 so slow" posts

Post by ckronengold »

Trying to figure out if my CPU is just in over its head for any type of h265 encoding. Was hoping to save some space on my NAS.

Testing with a rip of Greatest Showman 4k in an Intel i5-3570 with 16GB of RAM.

I'm getting FPS: 000.3 Avg FPS: 000.5
23:09:50 elapsed, 16:13:09 remaining.

Should I just wait until I upgrade or try encoding on my Linux server (Intel Core i7-8700, 16gb RAM)?
I don't think changing from "slow" to "medium" is going to make a meaningful difference here.

My settings:
- h265 10bit
- Framerate Same as Source
- RF20
- Encoder Preset: Slow
- Encoder Tune: None
- Encoder Profile: Auto
- Encoder Level: Auto
Extras: hdr:max-cll=4000,1000:master-display=G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1):deblock=-2,-3:strong-intra-smoothing=0:sao=0
Audio: TrueHD passthru

HandBrake version (e.g., 1.0.0):
Nightly 20190727200229-e30ed94-master (2019072701)

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

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

I should add, though, that the first 30 mins of the encode (which took nearly 24 hours) does look outstanding.

Yes, your processor is too slow to really take advantage of x265 encoding. There are not enough cores, and you can't even off-load things to QSV because the hardware doesn't support h.265. The CPU can only spin the bits so fast... :)

Awesome, thanks.
Guess I'll try with the Ubuntu machine and see how it goes.

For Ubuntu, you should use the "flatpak" distribution, available from the official handbrake downloads. The version that Ubuntu distributes is deliberately crippled by them.

Efficient encoding = slow
Less mature encoder = slow
Higher bit depth encoding = slow
Your CPU = slow

Add it all up... it's going to be real slow.

Now there may be some interlaced Blu-ray content, but 4K sources are highly unlikely to be. Drop the decomb filter, it's gotta be slowing you down significantly.

Is there a flatpak available for the nightlies? I don't recall seeing one, but I wasn't looking terribly closely. Or can I move to the official releases for doing the h265 10-bit stuff? (i'd read so may conflicting posts regarding how HDR metadata was being handled).

thank you so much for the tip. I'm sure that will help a ton regardless of which machine I'm working on.

The "medium" x265 preset could be about twice as fast as "slow", sometimes a bit more than that. The x265 "fast" preset should be 3 times faster than "slow", at least, and in some cases, up to four times the speed of "slow".

I've always done my h264 encoding at slow. Best quality at the smallest file sizes was always my goal. I set up an encode or queue up a few and let it do its thing while I go to work, or sleep, or whatever. But i was always in a 6-8 hour range, which was perfectly fine for setting up and going to bed or going to work.

My goal with the 4k UHD HDR encodes is to save as much space as possible on my NAS since I have the discs on a shelf anyway. This whole 'experiment' is because the Kodi interface is some serious eye candy for 110" screen & projector. But at 110" I certainly didn't want to give up any visible quality. I was just surprised to see 30+ hours for a single encode. I'm testing RF18 h265 10 bit on my Ubuntu machine right now (i7-8700, 16gb RAM) to see how long it takes, and will re-run when i get home from work (presuming its done) with your suggested changes to the settings.

If you really mean what you say, you should be using veryslow in both cases.

On the Nightlies for Linux, "Other platforms" is where the flatpaks are.

You are 110% right. I need to move the slider over.
Its been so long since I played with my presets, I forgot that I still had room to slow down.
It wasn't until I was staring at a 36 hour encode that it dawned on me to check.

just sharing for anyone who searches these threads.....

I tested (or started a test) of Greatest Showman 4k rip, using TrueHD passthru, and turned off deinterlace. Otherwise I kept the h265 10-bit settings as default.

Rip was 47.5 GB. CPU is Intel i7-8700 @ 3.20ghz (stock)
- RF20 medium took 7 hours and produced a 8.4 GB file.
- RF18 medium took 9 hours and produced a 11.3 GB file.
- RF18 slow is showing that it will take 19h 25m to finish (currently running)
- RF18 slower showed that it would take 60 hours to finish (I quit the encode)

That roughly follows the rules of thumb:

- 2x (or 0.5x) the time for each slower (or faster) encoder preset
- 6 points on RF to double or halve the size of the video track

RF 18 on slow ended up being slightly more than 28 hours rather than the estimated 19+ at the start of the encode.
Output file was 9.9GB, so roughly 20 hours more to save 1.5 GB in file size. Meh.
Doesn't change my opinion much on my end, unless I somehow see something dramatically different when I compare side by side.

- RF18 medium took 9 hours and produced a 11.3 GB file.
- RF18 slow took 28h 25m to finish and produced a 9.9 GB file.

The quality scale isn't the same across different speed presets. Pick your preset first, then find your RF value.

Can you explain? How do you pick your RF value if it isn't "more or less the same" across speed presets?
I understand that RF18 fast will yield a bigger file than RF18 slow, but wouldn't they both be RF18 quality(ish)?

Changing the speed can alter the size and/or the quality.

You pick your RF value from your own testing of different RF values after you've decided on a speed preset.
RF18 fast may be smaller than RF18 slow, and also lower quality.
