Handbrake Wishlist

[GhostMotleyX]

Please describe what you would like to see added to HandBrake:
#1 CUDA or NVENC Acceleration
#2 VP9 Support

Why would you like to see this added:
#1 It would drastically decrease render times, while only losing a small amount of quality (especially when using slower presets)
#2 YouTube currently doesn't support H.265 whereas they do support VP9

What version of HandBrake are you currently running:
0.10.2.7286 64bit version

What operating system and version and you currently running (e.g. OSX 10.11, Windows 7, Ubuntu 14):
Windows 10 64bit Build 10162

#1 CUDA has been replaced by NVENC so there is no point adding that. As for NVENC, there is no license compatible version with the GPL so can't be added. No idea if this will ever change.
#2 VP9 is planned but not until the libvpx encoder matures. See viewtopic.php?f=26&t=27343&p=149331&hilit=vp9#p149331 Not anticipating it'll be fast enough to add this in the near future.

What about VP9 encode from Skylake?

Not really helpful when you want the encoder to be available to everyone.

Thanks for the reply, still though if they can put any type of Hardware Acceleration into Handbrake I think they should, even if it won't be available to everyone at-least those with the hardware would be able to render videos much faster, 2 hours for a 20 minute video kills me on the inside. That is with DXVA enabled as well

License-compatible patches and ongoing support are welcome.

Turn of DXVA. I'd wager if it's being used, it'll be far far slower than deciding on that CPU.

Given DXVA is only used in a subset of situations, it may also just not be active, in which case it makes 0 difference to performance.

It's only really useful for low end hardware. Higher end hardware is faster so bottle-necks on it.

Just found this topic. Could you please elaborate on how the libvpx encoder needs to "mature"? Where does the limitation lie exactly? And what does this have to do with speed? The H.265 encoder is currently quite slow as we know, but at least gets the job done.

For constant quality encoding (the default mode for all of HandBrake's presets) libvpx is more than 3 times slower than x265. x265 is already slow enough to be borderline in usefulness.

For average bitrate encoding, libvpx is a little over 2 times slower than x265.

I forgot to mention, x265 can be made to encode quite a lot faster. I used essentially default settings for each encoder in my tests. x265 gets much faster when using it's "ultrafast" preset. There is a lot of flexibility in x265 to select the speed vs. quality vs. filesize compromise. It's preset and tune options make this easy. libvpx on the other hand is difficult to tweak and does not get all that much faster with different settings.

These are all things that I would expect to get better with maturity.

Hello, my wish for Handbrake currently is just 1 thing, ability to merge files with it.

[s55]

We've stated on numerous ocassions that file merge won't happen.
