SmoothVideo Project → Using SVP → how can I convert 24p to 60p without the smooth interpolation?
I just want the frames to be repeated for a demo.
For example, the video source is 24fps, frame 0, 1, 2, 3, 4, 5......23
the target would be 0, 0, 1, 1, 1, 2, 2, 3, 3, 3, 4, 4, 5, 5, 5,.......
I saw AviSynth has script SelectEvery(2, 0, 0, 1, 1, 1) can do this. but don't how to do it with SVP player. Anybody can help?:)
Why? Any player does it on-the-fly. It repeats every frame from 24 fps video several times to get 60 Hz.
en, I need this for a demo. and the sequence 0, 0, 1, 1, 1, 2, 2, 3, 3, 3, 4, 4, 5, 5, 5,....... should be kept exactly. Not sure if the player can ensure this or not.

Ok. What is bad in SVP official demo mode: SVP tray menu - Demonstration mode?
Left part of frame "Source" shows 0,0,1,1,1...
Right part of frame "Smooth" shows video processed with SVP

Thanks, Mag79.
Instead of the half frames, May I have a whole frame of 0,0, 1,1,1 "source" by "Frame interpolation mode: off" & "Target frame rate: 24 -> 60"? 
Yes. Exit SVP. Open ffdShow. Go to Avisynth tab.
write:
SelectEvery(2, 0, 0, 1, 1, 1)
enable option "Add ffdShow video source"
enable Avisynth option
OK

Many thanks!!!
My silly question is when will this change take effect? it'll change the default behavior after I click the apply? or I need to change somewhere in the SVP configuration? 
swiths
It will work till SVP is not loaded. When SVP will be launched it will disable user's avisynth-script and will use its own auto-script. After exit SVP user's script will be restored.
So, you don't need change anything else.
MAG79
a little bit confused. 
so you mean which player should I use for the 24p -> 60p playback?
Any player. For example MPC-HC from SVP folder after install Full version of SVP.
When I wrote SVP I meant SVP-Manager.

got it. so I need to close SVP manager to let ffdshow use the selectEvery script.
Many thanks for your kindly guidence.

You are welcome

Hi Mag79,
I've tried MPC-HC with AviSynth script: selectEvery(2, 0, 0, 0, 1 , 1) but the video cadence is not always as expected 3:2 style. After about 2 seconds, there's some incorrect cadences. Here is a snapshot. Each DWORD is a value generated from the frame content so that if they're duplicated, it means the frames are repeated.
Do you have any idea if I'm not using correct playback options like accurate/alternative vsync, or anything I can try to narrow down? for example, can we verify if AviSynth+ffdshow is doing the selectevery correctly? by dumping the frames to somewhere? Or it's related to the presentation during vsync?

If you want frame-accurate output then use ReClock. It can synchronize video framerate to display refresh rate by correcting speed of audio and video streams.
But frame time stamps marked red is abnormal in any case.
can we verify if AviSynth+ffdshow is doing the selectevery correctly?
Yes.
ScriptClip("subtitle(string(current_frame))")
selectEvery(2, 0, 0, 0, 1, 1)It shows frame number at left top corner of frame.
ReClock
Many thanks!
Do you mean ReClock is another directshow filter, as ffdshow can NOT support accurate frame output? does ReClock support MPC-HC also?
Yes. ReClock is another DS-filter. It is audio-renderer.
But No. inaccurate is not some filter. Inaccurate is any try to show 59.94 fps at 60.xxx Hz display. ReClock fixes it by change 59.94 speed to 60.xxx speed. See ReClock documentation for more info.
MAG79
oh? so I'd use ReClock + ffdshow + MPC-HC, right? I'll try to google ReClock.
as to the red stamped frames, is that because of tearing? but I remember I was turning on vsync, accurate vsync , alternative vsync.

ReClock official forum/site. See Readme file in the folder where application installed. Or in the Start button menu - Programs - ReClock - Read Me First! shortcut.
is that because of tearing?
I don't know is it tearing or not, but I see at your picture more than 2 identical frames at 5 positions.
alternative vsync
Use it if you really know what is it. I don't use it because I don't know. I use madVR's windowed overlay or fullscreen exclusive mode to avoid dropped frames.

thanks, i'll try madVR also. it's not installed by default.

MadVR has useful OSD statistics by Ctrl-J hotkey. Especially about dropped and pending frames.
What renderer did you use before?

I was using 'Enhanced Video Render(custom presenter)'.
[update]
haven't got chance to try ReClock but it looks MadVR has much better results now...
almost 247 of the total 256 frames are correct aaabb(3:2) cadence, also the red frames are not so odd as they're duplicate of previous or next frames.
So it seems it's the render/presenter's fault, instead of ddshow codec or AvisSynth's ?

Yes. I agree with you.

This renderer sometimes produces dropped frames. One of method to avoid drops in EVR CP is to enable fullscreen D3D.

This picture looks better 
Can you tell what tools are you using for that (Memory 1 / m_dwStat)?
Instead of ReClock you can also switch your display to custom refresh rate. For this you need to create custom mode and add it to list of display modes.
I added 59 Hz mode and costomized it manually in NVIDIA control panel as close as possible to 59.94 Hz

that is a memory dump debugger window running on a capturē device.
i am using a 60hz panel and madvr shows its 59.xxxfps. need i customize a 59.xxx hz refresh rate？
