Topic: No smooth motion on 24 to 60fps converted video

Hey, I've got bunch of videos where someone has changed the framerate from 24 to 60. The issue is that it's not really smooth 60 but just the same as 24fps would be. And the real problem is that SVP can't make that 60fps into 60fps smooth motion video. The smoothness remains just the same (= no smooth).

Is there a way to get these 60fps videos to play smooth on SVP? I was thinking of changing framerate to 24 using a third party program or change the framerate on MPC HC. So far, no luck. The third party tools made the video slow mo and couldn't get MPC HC do the trick.

Any ideas?

You need to decimate 24 frames from 60. You can use TIVTC plugin to this purpose. In your case use 4-in-5 decimation.

Thanks for you reply.

I tried tdecimate but couldn't get it quite work the way it would smooth the vid. The framerate got lowered though. I put it into ffdshow raw video filter's Avisynth section, under the default code there:

global svppath="C:\Users\(my user name)\AppData\Roaming\SVP4\"
try {
   import(svppath+"scripts\2002d2.avs")
}
catch(err_msg) {
   ffdshow_source().Subtitle(err_msg)
   WriteFileStart(svppath+"logs\err-2002d2.avs.log", "err_msg")
}

tdecimate()



I also tried different modes and with cycleR and cycle parameters. The fps dropped further and it resulted as imager stutter (bad frame drops).

Anyway, I put 2 samples on Google drive. The 25fps.mkv works well with SVP but the 60fps.mkv doesn't. Both are cut from 2 different sources. Could you or someone else play around a bit with the 60fps.mkv, use tdecimate or find another way to make it smooth, and tell me how to do it?

Here are the vids:

Re: No smooth motion on 24 to 60fps converted video

Thank you for the links.

I download and look to 60fps.mkv frame-by-frame. It has really 60 different frames in second. No duplicated frames. This video is already smoothed to 60 fps.
The problem is format of video. It encoded to AVC 10bit YUV 4:4:4. GPU acceleration of decoding is not worked to this format, so my core i5 gives me 100% CPU load with video stops while playing.

If reencode this video to AVC 8bit YUV 4:2:0 is will must work normal with GPU acceleration of decoding. And smoothly even without SVP.
