SVP 4.5 marks a new era for SVP: we can finally move away from the good-old ffdshow. ffdshow used to be a great piece of software and SVP won't ever be possible without it, however it isn't maintained for years now, doesn't support neither high bit depth colors nor HDR and doesn't work correctly anymore with the newer Avisynth 3.6. Luckily for us, a brand new "Avisynth Filter" (yep, it isn't a very catchy name) can do all of these! Many thanks to CrendKing @Doom9 who bring it to us. Please note that it's still work-in-progress, so we're not pushing every SVP user to switch from ffdshow right now. But you're very welcome to try it!

Thanks to the recent mpv commit we now have three ways to watch HDR content in real HDR mode (still no dynamic HDR though :()
1. mpv - good performance, supports 10-bit, Windows 10 only;
2. VLC - worst performance, 72 fps max, supports 10-bit, Windows 10 only;
3. madVR - best performance but 8-bit only and needs manual file renaming.

ffmpeg 4.2.1 by chenrui333 · Pull Request #42827 · Homebrew/homebrew-core

Sad news for Mac users: Homebrew developers recently removed mpv from Homebrew because of some odd misunderstanding with mpv developers. More details there: https://github.com/Homebrew/homebrew-core/pull/42827#issuecomment-521474699

We believe this can be solved and they will return mpv back soon enough, but right now there're no simple ways to install mpv with Vapoursynth on Mac.

We're trying to figure out a workaround, stay tuned.

Created with brew bump-formula-pr.

Good news everyone! VLC audio sync problems finally got fixed. This means you can use VLC 3 with SVP, at last.

The only major problem left is very low performance playing 4K, which is kinda sad because VLC is now the only video player capable of playing HDR content on the HDR screens with SVP enabled. We're working on solving this one too.

BTW, here's a guide to 4K/HDR playback with SVP:

An Introduction to the NVIDIA Optical Flow SDK | NVIDIA Developer Blog

Introducing full hardware acceleration for NVIDIA Turing GPUs (20xx + 1660) in SVP 4 PRO rev.160!

Thanks to the NVIDIA Optical Flow (NVOF) API we can now offload most of the motion vectors search job to GPU.
Note that these motion vectors are completely different from what we got from the "software" calculations, so the quality may and is differ and not always in a good way. Please consider this first version as a preview, we'll try to improve NVOF quality in future releases.

Sadly, macOS is not in a list of NV's supported platforms 🙁

More info here: https://devblogs.nvidia.com/an-introduction-to-the-nvidia-optical-flow-sdk/

Turing GPUs introduced optical flow, which computes optical flow between images at high performance. The Optical Flow SDK 1.0 now enables developer access.

It's the Black Friday, again 😀
So we give a 50%+ discount on everything, including purchasing "additional computers" from the License Manager, until Sunday.
Enjoy: https://www.svp-team.com/wiki/Purchase !

Please note that we're not planning to update the Free version anymore, so consider switching to Pro. There will be a full-featured trial version available very soon - in fact, macOS users already have it.

August 1, 2018

Just the summary of recent updates:

- Variable frame rate videos was a big problem for SVP in mpv/VLC since the first Vapoursynth-enabled version, but now this awkward issue is fixed. SVPcode transcoding now also supports VFR videos (needs the newest mpv 0.29 installed).

- SVPlight now supports Boblight protocol, which makes it also compatible with a popular software for DIY "ambilight" - Hyperion

Changelog - SmoothVideo Project (SVP) - frame doubling interpolation

Good news, everyone: new version is out!

This is generally a bug fix release (really long list of issues fixed), plus Apple TV support in SVPcast streaming extension and a few more cool features such as ability to "re-stream" videos (SVPtube -> high frame rate -> SVPcast). macOS and Linux builds will come in a few days.

Also, please consider updating SVP/cast/code translations in your native language! Thanks! 😉

+ mpv: automatically turn on deinterlace mode if needed = mpv: match SVP settings with the deinterlace mode set by user + "Is variable frame rate" profile condition + attempt to fix incorrectly reported source frame rate: "Treat 23.810 as 23.976" option + empty "outer lighting" for fixing stereo pai...
