Just had an even better idea. Let MPC-HC play the video directly, and make it load the 432hz audio track next to it by having both files with the same name but different extension. I can use Avisynth Virtual File System to expose the script as a WAV file next to the video file and it will load with it. Not sure if there's another way to make it load the audio track.

Has anyone done a benchmark of the SVP versions, Avisynth vs VapourSynth, x86 vs x64 ?

I just tried running SVP in a script in x64 mode. Performance is a LOT slower than x86!! What's up with that?

Are there knows issues with Avisynth SVP x64?

Why would you use SVP encoder if you're not changing the frame rate? If you just want to re-encode download FFMPEG and do it from the command-line.

You will *always* lose quality when re-encoding.

I tried taking the generated SVP script and merging it with the AVS file I'm opening in MPC-HC. In x86, the CPU difference is marginal. (but this workflow would allow for x64)

What surprises me is, there are more dropped frames when opening the script directly than when playing via ffdshow! When the script lags behind playback, then playback becomes all jerky and it doesn't recover well at all. Ffdshow appears to allow for smoother recovery and smoother playback.

Which brings up another issue I hadn't realized before. In scenes with high animations, with 55% CPU usage and 70-80% GPU usage, I can get tons of dropped frames! Even when opening the video file directly in the player with only SVP. What's causing these dropped frames? Obviously it's taking longer to compute highly-animated scenes, but the CPU is still half-available.

I had tuned SVP (and madVR) settings for my computer a while ago. But lately, when I play videos, I'm seeing a lot of lag. I need to tune down the settings quite a bit to get good playback. Can't exactly say when this started. I'm using Windows 10 laptop with Radeon 1050. The videos play fine some of the time, and at other times the CPU caps at 100% and it lags, and then it comes back to normal, and then lag again.

Has anyone else experienced a decrease of performance, and perhaps found the cause? It could be a Windows update or a graphics driver update or something else. Searching online, a lot of people were complaining about similar performance issues after the Windows Creative Update, but that's quite a while ago.

Just curious what others have to say.

With the current SVP Manager, is there any reasonable way I could implement this workflow? Perhaps initiate the playback and script into a separate player that SVP manages (would have to look at the best way to do so), and then play it into a player that I control.

madVR supports HDR content; can you get madVR to render HDR correctly when playing an Avisynth script file instead of opening the file directly? Or what's the problem exactly

I see you added a "Temporarily disable SVP" which can avoid me from killing the process to disable it; still have to see how to use that from code.

If I wanted to do this flow, I would have to:
- Let SVP open the video via ffdshow
- Intercept the generated AVS file
- Disable SVP
- Modify/inject the intercepted script into my player script
- Load it into MPC-HC

This could work but would cause even more glitching on loading videos.

Any way I can ask SVP to generate the script for a given video file without playing it? Or perhaps it would have to believe my own application is playing it and SVP would kick in while I control the playback?

Additionally, I'm just thinking -- it could be possible to run SVP in Vapoursynth (which doesn't support audio), then load that script in Avisynth and load the Audio alongside it. Is the performance and stability of SVP better in Vapoursynth than in Avisynth? As an additional benefit, then I can also run MPC-HC in x64.

MPC-HC can open 10-bit Avisynth script no problem. It views it like this

Cross-referencing this thread, such a workflow of loading the avisynth script into MPC-HC instead of capturing it via ffdshow would allow for 10-bit output.

When playing videos, I have this ridiculous chain:
- Video loaded via an Avisynth script to change the pitch from 440hz to 432hz
- Video passed to SVP via ffdshow
- Video runs through another Avisynth script
- Video is rendered in HPC-HC via madVR

I'm just thinking. Would it be possible to have a single Avisynth instance running, to inject the code that would run into the first script I'm loading? Then no ffdshow and only 1 Avisynth engine running, should improve performance and stability. But is there any way it can be done? The challenge would be getting the per-video configuration that SVP Manager needs to generate.

I think such feature would require a specific API support from the Manager; and it could notify to reload if settings change.

OK the videos where SVP doesn't work are Avisynth script files (attuning the audio to 432hz), and those that work are opening the file directly.

This used to work perfectly fine. What could have changed?

Playing this video

It renders correctly with SVP

After reinstalling Windows, I'm having some problem with SVP.

If I run it in MPC-HC with madVR enabled, SVP doesn't run at all, it says no active playback.

If I disable madVR, then it renders via SVP but it is extremely laggy.

What the heck is going on here?

After reinstalling (I chose to install also mvp x64 to try it), it says 32-bit core components aren't installed when playing in MPC-HC, and according to the setup utility, that's definitely installed. It looks like there are a few bugs with the installer.
