Topic: video delay and memory prob

I'm noticing a terrible video delay with svp 4 ....

if I only install svp 4 with everything without my k-lite mega codec pack, I do not notice delay... but there is no mpc-hc x64 included on the pack...... can u put together? thx.

but if I install k-lite first and svp 4 after, there is a horrible 0.25-0.5s delay with the sound, as on the other topic someone was saying that........ I changed everything, but nothing happened....

i have not noticed issues with k-lite 11.96...... but yes with this 12.02, which has updated stuff.... maybe the updated drivers have clash with svp 4.......

----------
on the other hand
man y of you might have seen it, but here it comes.. when I use x64 svp mpc-hc too, if you seek lots of times w/o closing video, the amount of memory used skyrocket..... I was watching lion king 10gb video 20000 kbps, and it started with 1gb till more than 5gb (memory used by video player) weird.

-----------
kind of liking 32-bit software and stuff again.... even for 4k 32-bit is acceptable... even if there is no nvidia cuvid... for me cuvid and dxva have similar performance.

Re: video delay and memory prob

SVP 64bit is currently experimental.

Does your audio issue exist with SVP 32bit?

Vapoursynth x64 for windows is coming. But 2160p will still require insane CPU

2160p:

1080p with vaporsynth :

1080p without svp (dxva copy back works quite well but only for 1080 content) :

Seek works much faster too.

"Vapoursynth x64 for windows is coming. But 2160p will still require insane CPU"

So what would be the recommended CPU for this? 6 cores and above?

Well it's likely that the VapourSynth version won't have higher CPU requirements, otherwise one questions the benefit of even switching from AviSynth on Windows.

Yes. For my PC its only few % higher than lav dxva+avisynth+madvr.

2160p is not that hard to play! (disabled (recize to screen off)) just require medium svp settings for normal play on a regularly fast computer and gpu.
