Support frame interpolation

[IceHismxx]

I enjoy watching anime with 60 fps and i know mpv supports frame interpolation natively or with open source stuff like vapoursynth. Is it possible to add this to iina?

[lhc70000]

IINA supports almost all mpv options.

If you are already a mpv user, you may continue using all your configs and scripts by checking "use config directory" in Preference -> Advanced.

If you don't use config files, you can also add following options in Preference -> Advanced to get it work:

interpolation=yes

See mpv documentation for more information.

According to documentation, you may also need to set

video-sync=display-resample

or any other display- value.

However please note that video-sync may not work correctly in v0.0.1. This problem has been fixed and v0.0.2 will be available in few days.

To support advanced motion interpolation, people often resort to compiling mpv with Vapoursynth support and then supplying own MVTools script or plugging tools like SmoothVideo Project. According to this thread on SVP forums, there would theoretically be no problem with enhancing the video with SVP if the mpv binary shipped with IINA were compiled with Vapoursynth support. Is that something that seems reasonable or doable?

For SVP support, please refer to #118.

Well, the video-sync=display-resample breeks in the new rendering mechanism. Here is a comparation between mpv and iina.

Any updates on fixing interpolation?

Just tried it on 0.0.12 build 37 and it is still not working.

@bodayw would you mind sharing how you test it on iina? I would like to follow up on this.

interpolation is the most important feature from mpv, and the major reason I choose mpv for now

[bodayw]

@jnozsc I always test it with a video clip that has a panning shot (e.g. the NCED of Carnival Phantasm) and judge by eye. On a 60 Hz monitor playing 24 fps video without interpolation, the judder should be obvious if you know what to look at.

You can probably also see if the estimated FPS reported in stats.lua is too high, as shown above, also mentioned in #741. #1542 might also be related.

Should be fixed in develop with #1542.

Sorry to necro this thread but I am new to INNA and MPV. Is there an easy way to enable motion interpolation? I have no clue what to do with the instructions provided here.
