blind-to-video - Converts blind video to a regular video
blind-to-video [-d] frame-rate ffmpeg-arguments ...
blind-to-video reads a blind video from stdin and uses ffmpeg(1) to convert it to a normal video format. frame-rate must be set to the frame-rate of the input video, lest the tempo in the output video be modified. You can use ffprobe(1) (an ffmpeg utility) on your original video to find out the frame rate:
|
ffprobe -v quiet -show_streams -select_streams v -- your-video.mkv | | ||
|
grep ’ˆr_frame_rate=’ | cut -d = -f 2- |
This value will be a rational value, which is supported. All argumnets after frame-rate (that is ffmpeg-arguments ...) are arguments that will be passed to ffmpeg(1) after the arguments that blind-to-video will create that specifies the input file and necessary metadata such as frame rate, geometry, and format, of the input video. Beginners are recommended to use -c:v libx264 -preset veryslow -crf 0 -pix_fmt yuv444p -- output-file.

Perform coarse colour-model conversion. This will increase the performance of the conversion, however, it the colours will not look correct, unless the -d flag was also with blind-from-video(1) and not colours have been modified between to the processes. |
