Cropping information on input frames ignored due to lack of API support.Īnd resulting video was only re-coded but not cropped. Video apparently needs to be recoded and sadly i was unable to use hardware encoding on my AMD APU computer:įmpeg -vaapi_device /dev/dri/renderD128 -i "input.file" -vf format=nv12,hwupload,crop=1920:816:132:132 -c:v h264_vaapi "output.file" This frame is located 132 px from top and 132 px from bottom. In another words: crop out video frame with a dimensions of 1920 px width and 816 px height. In another words crop the top and bottom black bar each 132 pixels.įmpeg -i "input.file" -vf crop=1920:816:0:132 "output.file"Ĭrop accepts values in pixels, crop=finalwidth:finalheight:horizontalcrop:vertica lcrop (so here i cut out first and last 132 pixels out of the original video height) And then manually adjust the values that are under "Auto crop" checkbox and preview until found good ones. check and uncheck "Auto crop", click preview button. How do you suggest to crop the video using ffmpeg command line on Linux (Windows is similar i guess) keeping aspect.ġ.
