Is there a 64-bit app for working with image sequences to replace Quicktime 7?

Solution 1:

ffmpeg

The command line tool ffmpeg can be used to create videos from images:

Solution 2:

QuickTime Player in Cataline (and probably earlier versions) allows you to import an image sequence exactly as with QuickTime 7 and export it as a movie.

Open QuickTime Player. Go to File > Open Image Sequence and select the images or folder that you want to use in your timelapse. Now you get an option to select resolution, frame rate, and encoding.

Note! I have had some issues getting it to import all selected images. What instead works for me is to select the folder with the images for my timelapse, then it correctly imports all of the images.

Unfortunately, I have not seen an option for doing the opposite in QuickTime Player in Cataline, i.e. importing a video and exporting it as an image sequence.
