Re: SSD-PCIe vs. SATA

Irrelevant. Unless you're encoding raw uncompressed video, even a mechanical hard drive will have no impact on encoding performance whatsoever. It may if you are encoding multiple videos at once. :D Bandwidth is not the bottleneck, but seeking. I would use SSD for source and spinning HD for output....

Re: i7 9750H, 630HD IGP, GTX 1660i showdown

Hmm, a 32 Mbps 1080p H.264 video file.

I bet it would be efficient (10 Mbps) and look just as nice if you re-encode it using x264 CRF 20.

Re: CPU for handbrake (4k UHD) and image editing ($200 - $400)

My favorite before reading this test was the Ryzen 7 3700X, but it looks like the 3900X is siginicantly faster. I have heard that there will be a 3900 without X, a few have been reported in the wild. The 3900 without X should have less TDP similar to the 3700X. Are you after raw performance? How ab...

Re: Ryzen 9 3900x X264 not maxing out all cores

I only have interlaced DVDs, so I encoded 8,000+ frames of same DVD using x264 at CRF 20, ref=3, bframes=6, others at default. Because it is MPEG-2, I got this warning: [mpeg2video @ 0x7f9438017b40] Application has requested 21 threads. Using a thread count greater than 16 is not recommended. I don'...

I didn't notice until now, but are you sure the filters-off is faster?

According to your log, filters on:

Code: Select all

[00:06:28] work: average encoding speed for job is 43.541725 fps
vs filters off:

Re: h264 more efficient than h265?

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.

Re: Handbrake and NVenc - best preconfigured settings

For me, because I'm encoding the movies for professional clients who can usually see a difference, I still use the plain ol' H.264 codec set to VerySlow. Even though my main machine is an 18-core i9-7980XE running at 4.2 GHz, it's encoding at 22 FPS (considering a 2-pass encode), or in other words,...

MediaInfo will give you the bits per pixel, which will reflect relative compression ratio.
Yes, but it does not tell us if we are able to compress the file further.

For example, the 25 GB file could be compressed to 5 GB. But it could also be that it remained around 25 GB after re-encoding.

Re: Speed, Quality, File-Size - Pick Two

The source file is about 25 GB. I use H.264 with 30fps, RF18 constant quality etc., which are the standard settings preset by handbrake. But - the resulting file size is only about 5 GB. How can that be? If the source file is from Blu-ray, it is only lightly compressed. Unfortunately, you cannot te...

x264 is fully deterministic unless you specifically tell it not to be though (even with VBV).
When lookahead threads > 1, the output size is larger. I forgot if it is deterministic.

And with 1 lookahead thread, there isn't much reason to use >6 threads.

Re: Difference in output files from CLI and GUI

I believe it is due to multithreading. When encoding a chunk, it may need to reference previous chunks. Earlier chunks may finish close enough that different ones are used on different runs. x264 also has this issue, but to a lesser extent. If you use more threads, space efficiency goes down a littl...

Re: From A Unique Perspective

On general encoding: IMO, if you are encoding 1080p or lower, just use H.264. :) Two years ago, H.265 looked like it would be the future, but it kind of fizzled out -- no doubt due to patent royalties. The good thing about x264 is that it is really easy to get good encoding, no secret sauce needed. ...

Re: Speed, Quality, File-Size - Pick Two

There is an asterisk for speed, quality and file size when it comes to video encoding.

It is not as simple as pick two of the three.

It is well-known that you can choose overly slow/insane settings that do very little or nothing for quality nor file size.

Re: Help with settings for AVI to h.265

As @musicvid said, you can just use x264. If you want to transcode a low-quality source, the first thing you want is to discover the "equivalent" CRF -- the CRF that will give you the "same" quality as the source. I tried x264, veryfast preset, CRF 22 (80.2 MB), 24 (66.8 MB), 26 (56.7 MB), 28 (49.0 ...
