64-bit app for working with image sequences to replace Quicktime 7

64-bitcatalinaquicktimevideo

I've been using Quicktime 7's "Movie to Image Sequence" and "Open Image Sequence" export and import options forever. It's useful for creating and working with time-lapses, modifying a single frame or a couple of frames in a video, creating short animated gifs, etc.

Unfortunately Quicktime 7 is 32-bit, so once I upgrade to Catalina it will be gone forever. I'd like a recommendation for a 64-bit app with similar features: the ability to export every frame of a movie to a sequence of still images, and construct a new movie at a specified frame rate from a set of still images.

Is there any good replacement for this Quicktime 7 feature? Free is optimal but not necessary.
