To be more precise, a similar delay is used, but from what I've found, it seems to be quantised.

I converted a couple of sequences of JPEGs into movies; the first had 554 images, the second had 665.

I tried integer delays (i.e. values for the -delay switch) from 2 to 11 and found that:

• 2, 3 and 4 all ended up with a delay of exactly 0.04 seconds between frames (equivalent, I believe, to -delay 4) in both movies, based upon the number of frames and the duration ffprobe (and my movie player, though this rounds to the nearest second) reported for the movie;
• 5, 6, and 7 all ended up with a delay of exactly 0.08 seconds (which is what I'd expect from -delay 8) in both movies;
• 8, 9 and 10 all ended up with a delay of exactly 0.12 seconds (which is what I'd expect from -delay 12) in both movies; and
• 11 ended up with a delay of exactly 0.16 seconds (which is what I'd expect from -delay 16) in both movies.

Have I missed some configuration? Even if I have, I assumed the delay shouldn't be quantised like this!

Thanks in advance of any thoughts.

What version of IM, on what platform? What were your exact commands?

IM will delegate the work to ffmpeg. If you add "-verbose" to the commands, I expect this will tell you the ffmpeg commands. What are they?
