50 to 60p for 3D

relaxvideo wrote on 5/7/2017, 12:14 PM

I'm in PAL country and record in 50p, but active 3D glasses need 120Hz minimum for flickerfree image. NTSC people are lucky, we not :( If i use 100Hz mode, video is smooth, but glasses flickers. When i play at 120Hz 3D mode it judders badly (like when you watch 50p at 60Hz monitor). I can convert to 60p with Twixtor but this is very time consuming even on my i7 pc. And i have a lot of videos.. I can convert in less time with Vegas to 60p, but then the panning (horizontal or vertical) doesn't look good.

Any other method, which is

- faster than Twixtor
- and better than Vegas?
(plugin, or vdub filters, etc)

thanks in advance!

You will find very valuable information in this thread. (especially the 3rd post)

That script in manolito's post does much better with relaxvideo's clip than the ones I posted above. No breaking up of those 2 masts at all. I think it was quicker too. I think I'll be switching to that approach in the future. Good job @johnmeyer!

In case you don't know, you need to put that jm_fps.avsi in your AviSynth autoload folder, for example C:\Program Files (x86)\AviSynth 2.5\plugins\. Then you can call it with a .avs script like this:

AviSource("d:\fs.avi")
ConvertToYV12()
jm_fps(59.94)

This is my current fully commented version of the same thing:

SetMemoryMax(3072) #3072 fastest for AVS or AVS+ x86. 4096 fastest for AVS+ x64.
SetMTMode(3, 12) #12 fastest for AVS. Remove for AviSynth+

#SetFilterMTMode("DEFAULT_MT_MODE", 2) #Only for AviSynth+

#SetFilterMTMode("AviSource", 3) #Only for AviSynth+

#Frameserve in RGB24 format (or RGB32 if AviSynth will not accept RGB24)
AviSource("d:\fs.avi")
ConvertToYV12(matrix="Rec601") #Rec601 is correct for encoding MagicYUV etc. in Vdub

SetMTMode(2) #Disable for AviSynth+

#jm_fps(29.97)
jm_fps(59.94)

#Prefetch(16) #12 fastest for AVS+ x86. 16 fastest for AVS+ x64. Only for AviSynth+

Thx, will try at weekend, we have lot of 3D projection now..

Nick's latest script with MT is the best and fast i think.

I used:

SetMemoryMax(1072)
SetMTMode(3, 12)
AviSource("\fs.avi")
ConvertToYV12(matrix="Rec601")
SetMTMode(2)
jm_fps(59.94)

If somebody can make better result with the same render speed, please share :)

thanks!

I tried it. Not an improvement, as it stands, for relaxvideo's clip.

While the script works great with full HD video, it doesnt work with 4k. Anybody know why? What should i modify? I try to convert 3840/25 to 3840/50, but got this error message:

I like to use this script again to convert 50p to 60p, and i don't know what happened with my system but for some reason its very slow, around 5 fps with a 1920x1080 h264 source file.

I use this script:

SetMemoryMax(3072)
SetMTMode(3, 12)
AviSource("\fs.avi")
ConvertToYV12(matrix="Rec601")
SetMTMode(2)
jm_fps(59.94)

Now i removed and reinstalled avisynth 2.60 ST, then overwrite the DLL file in win\system32 folder with MT version (20150220), and finally copied mvtools2.dll from here, removegrain.dll and jm_fps.avsi to the plugins folder.

It works, but very slow, i7 cpu usage is around 10-15%.

Why? It worked before with 3x realtime speed.

Look at your windows update history. If you didn't change anything then Windows almost certainly did. Roll the changes back one at a time until you identify the culprit.

I don't enable update, and still use win7 :)
