BLIND-FROM-VIDEO(1) General Commands Manual BLIND-FROM-VIDEO(1) NAME blind-from-video - Converts a regular, cooked video to a blind video SYNOPSIS blind-from-video [-r frame-rate] [-w width -h height] [-dL] input-file output-file DESCRIPTION blind-from-video converts the video, in the file input-file, to a for- mat usable by the blind tools, and prints the new video to the file output-file. input-file and, unless -L is used, output-file must be regular files. input-file must be a normal video file with a container (i.e. not raw video) that is supported by ffmpeg(1). It is unspecified what happens if input-file does not have exactly one video stream. All non-video streams, such as audio and subtitles are discarded. OPTIONS -d Perform coarse colour-model conversion. This will increase the performance of the conversion, but modifications to the colours will not produce the expected colours. This is useful for draft- ing or if you will not modify the colours. If you use this flag, you should also use it in blind-to-video(1), otherwise the colours will be modified. -h height Change the height of the video to height. -L Write to stdout that the number of frames in the video is 0. This allows you to use a non-regular file, including a pipe, as output-file. If you specify '-' as the output-file, the video is printed to stdout. This option is useful if you want to split a video, into multi- ple videos, as it allows to to split the video without having to store the entire raw video to disc. If you use this option, you can use blind-split(1) to write the actual number of frames to the head, if this is needed. -r frame-rate Change the frame rate of the video to frame-rate. This value can be a rational. -w width Change the width of the video to width.
