How slow does 100 fps or 200 fps drone footage play on a 24, 25 or 30 fps timeline?
Divide the timeline frame rate by the recorded frame rate; the result is the playback speed when every recorded frame is shown once. Example: 100 fps on a 25 fps timeline plays at 25 ÷ 100 = 25% speed, 4 times slower, so a 10-second clip lasts 40 seconds. The DJI Mini 4 Pro spec page lists 4K up to 100 fps and Full HD up to 200 fps as recording rates that play as slow motion.

Table: speed and slowdown
On a 24 fps timeline: 48 fps plays at 50% (2× slower), 60 fps at 40% (2.5×), 100 fps at 24% (about 4.2×), 200 fps at 12% (about 8.3×).
On a 25 fps timeline: 50 fps at 50% (2×), 100 fps at 25% (4×), 200 fps at 12.5% (8×). On a 30 fps timeline: 60 fps at 50% (2×), 100 fps at 30% (about 3.3×), 200 fps at 15% (about 6.7×).
How long the clip becomes
New length = recorded seconds × recorded fps ÷ timeline fps. 10 seconds at 100 fps on a 24 fps timeline: 10 × 100 ÷ 24 = about 41.7 seconds. 10 seconds at 200 fps on 25 fps: 10 × 200 ÷ 25 = 80 seconds.
Turned around: for a 30-second slow-motion shot at 4× on a 25 fps timeline, record 30 ÷ 4 = 7.5 seconds at 100 fps.
Which rates the Mini 4 Pro records
DJI's spec page lists 4K at 24, 25, 30, 48, 50, 60 and 100 fps, and Full HD at the same rates plus 200 fps; it marks 100 and 200 fps as recording rates whose video plays as slow motion. So the strongest 4K slow motion is 100 fps, and 8× on a 25 fps timeline needs Full HD at 200 fps. The same page notes that 4K at 100 fps with HLG or D-Log M is recorded in H.265 only.
Shutter for slow motion
Doubling the frame rate for the shutter gives 1/200 s at 100 fps and 1/400 s at 200 fps. Against 1/50 s, that is 2 stops (200 ÷ 50 = 4) and 3 stops (400 ÷ 50 = 8) less light, so slow motion in low light gets dark faster than normal-speed footage.

Questions
Is 60 fps enough for slow motion on a 24 fps timeline?
It gives 40% speed, 2.5× slower. For 4× or more you need 100 fps or above.
Can the Mini 4 Pro record 200 fps in 4K?
No. DJI's spec page lists 200 fps for Full HD only; 4K goes up to 100 fps.
Why does my 100 fps clip play at normal speed?
The editor plays it at its own rate. Set the clip to the timeline frame rate (often called conform or interpret footage) to show every recorded frame once.

We also make the Aerialgrade Drone LUT Pack: 20 .cube files with 4 conversion LUTs from D-Log to Rec.709 and 8 looks, each look as a D-Log-in and a Rec.709-in file, plus a PDF guide (USD 39.99, one-time purchase on Gumroad). It has no D-Log M conversion of its own: D-Log M footage is converted with DJI's free LUT first. This page is free and needs no sign-up; nothing is charged on this page.
