I have a large group (tens of thousands) of images which were captured to an SSD at the max speed possible, which was therefore not a constant frame rate. Because of this, when using FFMPEG to turn these into a constant frame-rate video it seems to speed up and slow down when it shouldn't.
Is there a way to tell FFMPEG to time the images based on the timestamp in the filename rather than a constant framerate?
For example, consider the following (contrived) list of files:
2019-01-28-08-00-28-000-000.tiff 2019-01-28-08-00-28-700-000.tiff 2019-01-28-08-00-28-900-000.tiff
These should be three sequential frames, but should have varying times between them. Then I can use the minterpolate filter to make it a smooth transition.
