Video Slave 3 - Dealing with high frame rate content


Video Slave allows for synchronized playback of clips with up to 60 frames per second. This will allow you to use it in all common situations in the current postproduction market (should there be a scenario we've missed, please This email address is being protected from spambots. You need JavaScript enabled to view it.). MIDI timecode (MTC) however doesn't support frame rates higher than 30 frames per second.

Thus, the timecode frame rate of a particular movie file can possibly be different than the movie's video frame rate.

In the PAL world, you could have a movie with 50 video frames per second which runs with a timecode frame rate of 25 frames per second for example.

In the playlist, this is indicated by two icons and their corresponding values:

Video Slave then simply translates the incoming timecode to the correct frame index and the movie will play back in sync. When adding a high frame rate movie to the playlist, Video Slave will automtically apply the correct frame rate for you. You can of course still modify the start timecode address and the timecode frame rate manually by clicking the "TC" button.
