There seems to be a GUI application (DAIN-App) that can interpolate video frames with DAIN (Depth-Aware Video Frame Interpolation), so try it
- Try DAIN GUI application, DAIN-App (Alpha 0.31)
- Now avairable 0.40
- Convert 15fps video (mp4) to 4 times 60fps
Not To Do
- The source of DAIN itself is open to github, but this time i will not do it
Paper: Depth-Aware Video Frame Interpolation
Original video 15fps
Converted video 60fps (4x frame interpolation from 15 to 60)
Compare x0.25 Left: input <-> Right: output
The effect is slightly difficult to understand in the sample video, but it was able to improve FPS by frame interpolation of the video (2 times, 4 times, 8 times can be selected).
The conversion process takes a lot of time.
How to use (Usage)
Download from “Download” and extract the rar file to any folder.
The size after expansion is about 1.6 GByte.
Lanch “DAINAPP.exe” in the extracted folder.
Run frame interpolation
Basic usage is as follows.
- “Input File” : Select source video file
- “Output Folder” : Select output destination
- “Interpolate 2X”, “Interpolate 4X”, “Interpolate 8X” : Select the frame interpolation magnification
- Press “Render”
The following console is displayed during conversion.
The estimated time to complete conversion does not appear, but the conversion process takes a long time.
It takes several hours to convert a movie FullHD (1920×1080) of 30fps to 60fps.
Conversion is completed when the following dialog is displayed.
If out of memory error occurs when trying to convert a high resolution video, check “Split frames into sections.”.
If the original frame image is blurred, the interpolation result is not so good, but if the original image has a solid shape, the interpolation will be relatively smooth.
