that would be great!!! i like the M version!

Maybe it's because you don't have a custom path to the included portable python.

would it be this? if everything is already pointing to the internal portable
and I had uninstalled the installs
I also did it on a clean windows installation, pointing only to the portable

For a while now I've been using Turing Nvenc my encodes (1080p) I have just got a Ryzen 3900x and was wondering if there's any settings out there I can use that would get me the same quality output but for potentially less bitrate/file sizes?

This is what I use for 1080p Blurays

--vbrhq 4400 --codec h265 --preset quality --profile main10 --level 5.1 --output-depth 10 --max-bitrate 4400 --aq --aq-temporal --bref-mode each --bframes 5 --ref 15 --gop-len 240 --lookahead 32 --output-buf 32 --vpp-unsharp radius=2,weight=0.65,threshold=20 --vpp-edgelevel strength=6.0,threshold=16.0,black=0,white=0

And this for older Blurays with a lot of noise

--vbrhq 4400 --codec h265 --preset quality --profile main10 --level 5.1 --output-depth 10 --max-bitrate 4400 --aq --aq-temporal --bref-mode each --bframes 5 --ref 15 --gop-len 240 --lookahead 32 --output-buf 32 --vpp-knn --vpp-unsharp radius=2,weight=0.65,threshold=20 --vpp-edgelevel strength=6.0,threshold=16.0,black=0,white=0

Should I change over to x265 or continue with Nvenc and is there anything I should change?

If anyone could point me in the right direction that would be great

Could someone provide me with some pointers on how to enable FFV1 version 3 encoding (-c:v ffv1 -level 3) in Staxrip, using ffmpeg of course? I can't figure out how to add it to encoding options. Using beta 2.1.1.1, btw. Thanks.

[Patman]

updated some tools for staxrip...

Currently this is only possible with the command line.

Okay, thanks. No wonder I couldn't figure it out

whats the difference between an msvc version and gcc? method of compiling? same results? thanks!

both status are OK

Which GPU is in use?

Staxrip 2.1.1.1 beta stops processing on an error before writing a single frame when trying to output ProRes. Same job works fine in 2.0.8.0 Stable (edit: after it prompted to install Avisynth). I'll add what little information I can gather of the crash shortly.

Job: deinterlacing and IVTC'ing a music video.
TFM()
TDecimate(cycle=25,cycleR=5)
DeBlock QED (defaults)
VagueDeNoiser (defaults)

Output to ProRes normal profile.

update: Figured out why 2.1.1.1 beta throws in the towel. Avisynth+ was not installed. Odd though, I have done perhaps two dozen jobs on 2.1.1.1 and it never complained about Avisynth missing. I ran 2.0.8.0 the first time on this PC today; it told me to install Avisynth, and once I did that, 2.1.1.1 began outputting ProRes as well.

(Sidetrack: Could someone shed some light on why the CPU load remains at 4% for the job mentioned above? I get 10fps out of StaxRip with that 4%. Would be awesome to get the job done faster; where's the bottleneck?)

MSVC (Microsoft Visual C) and GCC (GNU Compiler Collection) are different compilers. You are right with the statement that the methods of compiling are different. As a result, there are performance differences in the builds.

@colinhunt

2.1.1.3 is portable, I've not installed avisynth or fftw, tried all your configuration and it worked fine.

A lot of AVISynth filters perform really well when using PreFetch. Look through the menus and for the MT Mode stuff and you should find the option to set the number of threads (that's the prefetch). If you have 8 threads on your CPU, try setting PreFetch to 4, or 6, or even 8. You can really get a remarkable speed bump this way.

One note: I have an AMD 3950X with 16 cores / 32 threads. I found the sweet spot to be between 12 and 16 threads when using X265. Just because you have a lot of threads does not mean you will get a speed bump beyond a certain point.

The rule is simple. Always use value equal to number of physical cores not virtual ones. With higher value than number of cores you will notice choking effect. (cpu usage drops constantly)

@stax76 is there anyway to setup the program to where the video bitrate is tied to (x264/x265) preset instead of the template? Similar to how the CRF value is tied to it?

In the x265 dialog the Custom tab can be used for this, custom switches override GUI switches.

Thank you for this information!

@stax76 - I know you are busy with tons of stuff. IDK if you would want to do this, but could you add a way to setup more then just 2 audio tracks. For those rare films/etc where there is 3 or 4 of them?

Also is there anyway you could add a DTS down mix to core option for the audio section? You can do this with ffmpeg via a command like this "-c:v copy -bsf:a dca_core -c:a copy" and I know there is a way to do it with mkv.

Thanks!

If you are not batch processing you can add more audio tracks in the Container Options, it has an audio Tab.

For that I would need more info, ideally on the issue tracker, mediainfo for the input file, command line and mediainfo for the output file.
