I rendered 250 frames to png for an animation.
I opened these images as
Image Sequence in QuickTime (10.5), and set the frame rate to 25 per second. This should give me a movie of 10 seconds.
I got a 10 second movie, BUT all 250 images play within the first 4 seconds, and the remaining 6 seconds are just a still frame of my 250th image!
When I enter other frame rates, like 60 / second, I get a 4 second movie, but all the movement is in the first 40%, then only a still frame.
How can I create a movie from my 250 png images that actually plays at 25 fps?
I don't have to stick to QT, it just seemed the easiest option. Anything on macOS would be ok. I had the same problem in Compressor though.
EDIT in response to Allen Simpson's easy-to-follow reply (thank you!)
Unfortunately same result as described above.
Result: a 10s movie clip with all the movement in the first 4 seconds and a still frame for 6 seconds... Ouch! Can't get my head around this. Any suggestions?
