Yes i mean duration. how much seconds should i give for duration to play 24 fps. Because i read something about this subject. Her channel name is Gal. She say if you want to 24 Fps make duration 0,06 second. How is possible? 24 Fps mean 24 photo in 1 second? It is very complex.
You are overthinking this.
When making a stop motion animation, the only thing you need to consider is how many individual still shots you want displayed per second of playback.
When you import the stills into Premiere, you can set their duration. So if you want two stills to displayed every second, and you are working on a 24fps timeline, you would set the imported stills import duration to 12 frames each. 24fps = 1 second, 12 frames duration still "A" plus 12 stills duration still "B" = 1 second of playback.
If you were using a 30fps timeline, the same process would apply:
To display 2 still every second on a 30fps timeline, you would set the imported stills import duration to 15 frames each. 30fps = 1 second, 15 frames duration still "A" plus 15 stills duration still "B" = 1 second of playback.
The smoother you want the stop motion effect to be, the more individual still per second. The jerkier, jumpier you want the stop motion to be, the fewer individual stills per second.
Make a test with 2 stills per second (which will be 1/2 the frame rate of the sequence) and then adjust from there. If you want it jerkier, reduce the stills per second - smoother increase the still per second right up to the frame rate of the sequence.
