This beta has a new feature to allow frame-interpolation rate conversion using the “Convert” feature:
When converting a clip, there is now an advanced option to Override frame rate and set Frame rate conversion = Motion Compensation.
The process to use this could be:
- Set the video mode to have frame rate of 60fps
- Open a source file with 30fps frame rate
- Observe that every other frame is duplicated by stepping frame-by-frame in the source viewer
- Select “Convert” and choose frame rate of 60fps and conversion mode = motion compensation
- Open the converted file when the conversion is complete
- Observe that every frame is unique by stepping frame-by-frame in the source viewer
The interpolation uses the ffmpeg minterpolate filter. Fair warning: the process is slow. I get about 2fps on my computer during the export. Also, the interpolation is not perfect and sometimes results in artifacts. The conversion feature also offers a “blend” mode which is much faster might be preferred by some people.
Testing/feedback on this would be welcome.
