Converting 29 FPS to 59, but the video is sped up

[Isac.martins]

I'm trying to convert a video from 29 fps to 59 with ChangeFPS (to make it fluid and smooth) in Avisynth, but the result of the video is completely accelerated, could anyone help me with a script for this?

Before changefps("ntsc_double") put a line above it with assumefps("ntsc_video"). If the video is vfr it will lose sync but for cfr wit should work fine.

It really went out of sync, the audio was delayed, was there any way to adjust this with a line or would it only be in the editing program in this case?

ChangeFPS should normally decimate/repeat frames to give the new rate. It wouldn't change the
speed, nor would it make motion look any smoother

What is your entire script?

Oh, really?
And what should I do to really make it look smooth without losing image quality? It's possible?

If your video is interlaced you can just bob-deinterlace it

AssumeTFF()  #or BFF if the source is bottom field first
QTGMC() #or use a bobber of your choice

If it is progressive you would have to apply a temporal interpolator, like FrameRateConverter or RIFE

He's already progressive
I have little knowledge of frame conversion, how would I do this FrameRateConverter or RIFE interpolation?

[dannyboy48888]

Try
FFMPEGSource2("video.avi", atrack=-1, fpsnum=30000, fpsden=1001)
Also try using lsmash if it still act up. Both are ffmpeg based but I've always had 1 get it right if the other didn't as they index differently.

Are you sure it is progressive? Or is it telecined film? If so you would have to IVTC (Inverse Telecine) it at first.

For framerate conversion see:

Some comments on your script, as you were asking help on YouTube
- DeFlicker should be first
- DeScratch should be second
- TemporalDegrain and TTempSmooth are similar. Use just one, for example TemporalDegrain2 with TR=3
- 3 different sharpeners to obtain what?
- Lanczos4Resize can be replaced by Nnedi3
- sharpen after denoise
- sharpen before of after upscale according to your source and preference
