Twixtor App

The Precise mode implements our Machine-Learning model, the faster processing mode implements classical Twixtor Best Optical Flow. You usually use Precise for lower frame rate like 24P and fast motion.

Currently supports the basic video formats supported by Mac (mov and mp4) and Windows OS. For Windows: HEVC/H.265 use the official HEVC Video Extension from the Microsoft Store. For broader codec support, the free K-Lite Codec Pack is available from the official Codec Guide website.

Properly handles video shot on phones with variable frame rates (VFR) automatically. With that you avoid stuttering and time jumps when playing back slow-mo. See documentation to properly export from your phone to your desktop for Twixtor without reencoding.

It does support 10bit mp4 video inputs. No known resolution limits. Does not yet handle Log and HDR (e.g. HLG) video always very well and RAW formats, you will need to use plugins version for that.

Option to time-stretch (speed change) or time-remap audio when using Speed Ramping – modifying the pitch to avoid the chipmunk effect. All processing in 32b float with proper pitch shift and VFR movies maintain audio sync. You can even export audio by itself.

You can adjust the output bitrate when you want to create high-quality intermediates. Likely a good thing to avoid data loss to encode at 1/3 higher bitrate than source. We also provide TIFF sequence option for lossless output.

Comes with a key-frame editor to create arbitrary speed ramps, and select in and out point to keep. Displays how many frames the movie will be based on speed and output FPS.

Should run on pretty much anything, of course at a different render speed. If you have higher resolution videos and a very old GPU or a tiny integrated GPU, switch to Twixtor Classic on CPU.
