SMPlayer Support Forum

can this application do frame doubling like MPC?

Not "this" application since smplayer is just a front-end / gui interface to the mplayer media player but mplayer itself.

The answer I think it's "yes" since mplayer can do "double framerate" - I am not sure though whats the mpc feature - through the yadiff filter.

To activate it: Video / Filters / Deinterlace / Yadiff (double framerate).

Be careful since the feature is quite resource consuming especially if other video options / filters are activated.

Cheers

PS
If you use mplayer2 I am not sure if that player supports the yadiff video-filter.
