Frame Interpolation with RIFE

RIFE

Note: RIFE only operates on a 64bit system with the latest graphic cards. RIFE is a high-quality frame interpolation filter, meaning it will smooth out videos by re/creating frames that are missing, such as after duplicated or blended frames have been removed by other filters, for example when processing cine film that has been captured by a video camera (telecine). It will interpolate between two frames and create an in-between frame. This results in smoother video. The RIFE filter comprises two parts: the filter files themselves, which are included in the plugins folder in the above zip package, and the RIFE models, which are a 1GB collection of files and folders which detail the various models. I haven’t included the models folder in the above download because of it’s size; if you would like to use RIFE: • go to the Github RIFE page • click on the “Latest” button on the right • click on the link to the models to download the zipped models folder. Assuming you have set up AVISynth as I have described above, the models folder needs to be placed in the avisynth+\plugins64+ folder: The actual model number to be used in the AVISynth script is shown against the folder number is shown lower down on the Github page linked-to above. For example, folder 4.6 (True) is model number 24. Note: only models using 4.1 and above will allow adjustment/manual setting of the frame rate. Lower models will only double the original framerate. A typical RIFE script would look something like this, with the user-variables in blue: v=ffms2("H:\Magix Info\Jak\Deinterlaced 00059.m2ts") a=LWLibavAudioSource("H:\Magix Info\Jak\Deinterlaced 00059.m2ts") AudioDub(v,a) # RIFE only works with RGB floats z_ConvertFormat(pixel_type="RGBPS", colorspace_op="709:709:709:l=>rgb:709:709:f") # motion interpolate to 50 fps Rife(gpu_thread=1, model=11, fps_num=50000, fps_den=1000, sc=true, sc_threshold=0.12) # back to YV12 z_ConvertFormat(pixel_type="YUV420P8", colorspace_op="rgb:709:709:f=>709:709:709:l")
