Tmix
This simple batchfile is a wrapper for the ffmpeg tmix video filter.
It can be useful to quickly convert high fps footage into lower fps with frame blending.
You may want to use it to makes smaller files and can be decoded faster in video editors, to help that further the ffmpeg arguments are using the libx264 codec with fastdecode tuning, which allows for even less preview lag in e.g. VEGAS Pro.
It can save considerable amounts of render time if you are editing a long video and exporting it multiple times because you're not wasting time on the frame blending.
