Preview images from a directory containing many images using the Python package napari
The following command will create an MP4 video out of all the images at the
location path/to/images/ with a title that begins with image_prefix_ and
ends with a number with leading zeros that make the number three characters
long and a file suffix .png. The video will have the replay framerate of
10 fps. The option -pix_fmt yuv420p specifies a pixel format that works
well for MP4 videos.
ffmpeg -r 10 -i path/to/images/image_prefix_%03d.png -pix_fmt yuv420p -vf "crop='iw-mod(iw,2)':'ih-mod(ih,2)'" path/to/video/video_name.mp4
Alternatively, you can set an experiment name:
exp=experimentName && ffmpeg -r 10 -i path/to/parent/$exp/$exp_%03d.png -vf "crop='iw-mod(iw,2)':'ih-mod(ih,2)'" -pix_fmt yuv420p path/to/save/location/$exp.mp4
However, these commands will only work if the frame images each end with a
three-digit number (padded with zeros). For a two digit number, the filename
%03d in the filename would need to be replaced with %02d.
