Let’s say your video has some ticker text at the bottom and you want to crop it out. Remove $x pixels from either side of the video: crop=in_w-2*$x:in_hĬrop A Video using FFmpeg from the Bottom OnlyĪ quick example to drive home the point about cropping.Remove $x pixels from the top and bottom: crop=in_w:in_h-2*$x.ffmpeg -i input.mp4 -filter_complex "crop=in_w/2:in_h/2" -map "" output.mp4 Here is an example of cropping a video in FFmpeg using variables instead of specifying the literal pixel coordinates. The input video’s width and height can be denoted by in_w / iw and in_h / ih respectively. We can implement the video cropping command using variables to denote the video parameters.

# $1 - where to move images from (SD card) I am by no means an expert in Bash, so there is plenty of room for improvement in these scripts, such as auto-grouping time lapse sequences, and changing the cropping settings. I did not write a script for this, but it should be fairly trivial to do so. With the help of Google, I was able to piece together some scripts to help me convert these to mp4 videos on my MacBook.Īssuming the images have been offloaded from the GoPro’s SD card, group each series of time lapse images into a separate directly.
