Animating a Sequence of Images with Control Variables

Hi,

This is my first post to the forum, so forgive me for my novice-ness. I'm not even sure if this is the right topic forum I should be in. I'm self-taught when it comes to programming and languages.

Anyways, I have used ffmpeg to split a video into individual frames, and I'm adding my own frames, as well. What could I use to animate the sequence of images, but also have a control to how fast the images are being processed, like having a minimum of 30 frames per second and up to 120 frames per second? I have taken a brief look at MaxLoader/Greenstock, but I don't think it can get the job done that I want. If I can get this done that isn't through a browser, that's what I would prefer. Thanks for any help!
