Catframes

The program selects the video resolution in such a way that it does not reduce the sharpness of most images.

Overlays

Fault tolerance

FFmpeg is great. Catframes uses FFmpeg. And yet they approach the same situations in the opposite way.

FFmpeg is fail-fast. Catframes is fault-tolerant. FFmpeg stops working when problems occur in order to prevent the result from containing errors. Then a person can fix the problems and run it again. On the other hand, Catframes were created with the expectation that getting a video is more important than finding out about the problems that have arisen. It isolates a problem and continues to work. Warnings are embedded directly into the video stream.

Stable quality

Catframes hides the complexity of the quality settings behind a simple 3-way switch. The quality level here roughly means the value of the structural similarity index measure (SSIM). Regardless of the video resolution, frame rate, the selected file format (MP4, WebM) and the encoder used in the end, this index changes slightly.
