How To Convert Any Video File to 60fps

PatrickJackson wrote on 10/9/2017, 8:34 AM

If you want to take advantage of Vegas' 60fps feature, normally your file would have to be 60fps as well. However, there are two methods I know off that you can use to cheat this.

The first, and most easiest method in my opinion, is to use an exploit discovered by one of the YouTube channel I'm subscribed to. Simply speed up or slow down the video by at least one frame (you do this by holding Control and dragging the clip. Dragging it to the left speeds it up, and dragging it to the right slows it down), and it will adjust the framerate accordingly. It doesn't actually matter how fast or slow you make it, but preferably you want to make it to the point where it isn't noticeable.

The second method is to use a free program called "Handbrake" (https://handbrake.fr/).This is pretty straight forward. Simply tell it you want to convert your file to 60fps, and it'll do it for you. It might require some fiddling to make your clip look right, but it's a very popular option (from what I hear, it works surprisingly well with VHS transfers).

Hopefully, this helps.

Not sure what this whole post is about. Do you mean converting 60i to 60p or 59.94 to 60.00? or 29.97 to 60.00? Care to explain more in detail?

You don't just "tell" Handbrake to encode 60 fps. It will duplicate frames just like Vegas or anything else. The BOB filter in handbrake works well with interlaced source, however.

Patrick, please explain why you want to have 60 fps output if your underlying content is not 60 fps.

Personally, I’m not jazzed about 60 fps just for the sake of having 60 fps.

@john_dennis

There is a large body of urban myth on the topic of 60 fps for its own sake, regardless of how one arrives at it or what damage it does to source quality. The phrase "fluid motion" comes up a lot in these discussions, which as the apparent widespread eagerness to dupe frames indicates, is mostly just make-believe.

There is a segment if gamers who insist they are so hypersensitive to screen flicker that they can barely tolerate 60fps, but duping frames would do nothing for these individuals, because the temporal flicker rate is still 30fps.

Even the most sophisticated BOB algorithms do their fair share of damage to shadow detail by adding noise (yes, I ran the tests).

I would assume it is so your video matches the refresh rate of 60 cycles on a computer monitor.

The best method (in my opinion) would be Avisynth + QTGMC for interlace sources or Avisynth + Interframe for progressive sources (uses SVP).

Both interpolate additional in between frames - no dupes.

If you do the vegas timestretch method mentioned above you'll have different results depending on whether or not resampling is disabled.

The only progressive frame-interpolation scheme I've seen that doesn't wreck native quality is Twixtor.

This, based on a @johnmeyer script, is straightforward and does very well in my experience. This is an evolution of it, with much recent development effort, but not necessarily any better.

And another variation on the theme for those that prefer a GUI: http://www.thinbasic.com/community/showthread.php?12274-V1-SlowMo-tool-to-aid-producing-slow-motion-video&highlight=petr

Related: I SEE a difference in frame rate reviewed when watching 30fps, vs 30p doubled and displayed at 60fps.

I know the frames are just doubled, but that looks better being pushed at me at 60p. Why is that if it is exactly the same thing?
