NAME blind - Collection of command line video editing utilities DESCRIPTION blind is a collection of command line video editing utilities. blind uses a custom raw video format with a simple container. If you have a video file you want to edit, you first have to convert it with blind-from-video(1). To be able to play your video in a video play, you have to convert it with blind-to-video(1). Raw video takes up tremendous amount of space, you should therefore avoid storing the video without first convert it with blind-to-video(1). UTILITIES blind-arithm(1) Perform simple arithmetic on a video blind-cat-cols(1) Place videos side by side blind-cat-rows(1) Stack videos vertically blind-colour-ciexyz(1) Convert CIE XYZ for use with blind-single-colour(1) blind-colour-srgb(1) Convert sRGB for use with blind-single-colour(1) blind-concat(1) Concatenate videos blind-convert(1) Change pixel format of a video blind-cross-product(1) Calculate the cross product of colours in a video blind-crop(1) Extract subframes for all frames blind-cut(1) Retain consecutive frames blind-dot-product(1) Calculate the dot product of colours in a video blind-dissolve(1) Fade a video by chaning it's alpha channel blind-disperse(1) Framewise split a video into multiple videos blind-extend(1) Add margins to a video blind-find-rectangle(1) Locate a coloured rectangle blind-flip(1) Mirror a video vertically blind-flop(1) Mirror a video horizontally blind-from-image(1) Convert an image to a frame blind-from-named(1) Receive a file descriptor blind-from-portable(1) Convert a video from a portable format to a processable format blind-from-text(1) Convert text to a video blind-from-video(1) Converts a regular, cooked video to a blind video blind-gauss-blur(1) Apply Gaussian blur to a video blind-interleave(1) Framewise interleave videos blind-invert-luma(1) Invert the luminosity of a video blind-make-kernel(1) Create a custom convolution matrix blind-next-frame(1) Extracts the next frame from a video blind-premultiply(1) Premultiply the alpha channel of a video blind-quaternion-product(1) Calculate the quaternion product of colours in a video blind-read-head(1) Reads the head from a video blind-repeat(1) Repeat a video blind-reverse(1) Reverse a video blind-rewrite-head(1) Rewrite the head of a video blind-rotate-90(1) Rotate a video 90 degrees clockwise blind-rotate-180(1) Rotate a video 180 degrees blind-rotate-270(1) Rotate a video 270 degrees clockwise blind-set-alpha(1) Multiply the alpha channel of a video blind-set-luma(1) Multiply the luminosity of a video blind-set-saturation(1) Multiply the saturation of a video blind-single-colour(1) Generate a single-colour video blind-skip-pattern(1) Skips frames in a video according to pattern blind-split(1) Split a video, by frame, into multiple videos blind-split-cols(1) Split a video vertically into multiple videos blind-split-rows(1) Split a video horizontally into multiple videos blind-stack(1) Overlay videos blind-tee(1) /dev/fd/ aware tee(1) implementation blind-time-blur(1) Draw new frames on top of old frames with partial alpha blind-to-image(1) Convert a frame to an image blind-to-named(1) Send a file descriptor blind-to-portable(1) Convert a video to a portable format blind-to-text(1) Convert a video to text blind-to-video(1) Converts blind video to a regular video blind-translate(1) Perform framewise translation of a video blind-transpose(1) Transpose a video blind-unpremultiply(1) Unpremultiply the alpha channel of a video blind-vector-projection(1) Calculate the projection or rejection of colours in a video blind-write-head(1) Writes the head of a video SEE ALSO ffmpeg(1), ffprobe(1), convert(1), sox(1), rubberband(1), soundstretch(1) blind's website: .
