The short version

Matching profiles: match contrast and saturation on the waveform, not exact colour; 'matching D-Log to Hybrid Log Gamma, you're going to have to add a little bit more contrast than you think' - and boost midtones on the curve for 'micro contrast pop.' Cloudy-drone vs sunny-iPhone is the hard case; HLG is his middle-ground profile.
Hyperlapse: interval = seconds between frames, length = output duration at ~25 fps; shorter interval = smoother and slower with room to speed up in post; a 20-second, 4-second-interval arc is a 40-minute flight; dark ND so the shutter is about half the interval.
Two reviews, one headline note: mask and darken the sky. Also cut earlier on the beat, trim static starts and over-run ends, no jump cuts, recentre the subject in an orbit, start the ramp earlier. Snow: 'go for it' - it's fog near freezing that ices the props, and whiteout breaks visibility rules.

Part 107 prep before owning a drone

A free two-hour YouTube video and practice tests got him through; the test has since added night flying.

Tony Northrup's ~2-hour video plus online practice tests; the exam was updated after he took it (night section added); register the drone under Part 107 from the start; he has considered a prep mini-course and may add a lesson of free links.

Why it matters

Matching HLG, D-Log, Normal and iPhone footage

Match contrast and saturation; the colours needn't match unless it's the same scene.

He shoots mostly HLG on the Air 3 now. Compare highlight and shadow levels on the waveform, adjust contrast; D-Log is flatter than HLG so needs more contrast than expected; the Air 3's HLG has an HDR-like light/dark separation the Mavic 3 lacks; push midtones on the curve. The student's river survey was shot in Normal because the caretaker watched the live feed; his iPhone stills were sunny, the drone day cloudy - 'only so much you can do' but a lot; D-Log Assist adds a little in-camera contrast; he offered to build a lesson from the clips. CBR vs VBR: keep VBR - all his cameras shoot it.

Why it matters

The seed of the later Color Match lesson.

Hyperlapse interval vs length, and the shutter rule for smooth motion

'The interval setting is how many seconds it takes to take a picture of the next frame... the length is telling how long the video clip will be.'

Output is compressed to ~30 (really ~25) fps; longer interval = faster time and bigger jumps; shorter = smoother, slower, and can be sped 2-3x in post while a long interval can only go faster. Example: 600 frames / 20 s at 4 s interval = ~40 minutes of flight - a Mavic 3 battery - for one arc. Jitter fix: dark ND or stopped-down aperture so the shutter is ~half the interval, the 180-rule idea for stills. A proper hyperlapse lesson was still to come.

Why it matters

The maths behind the night and 96-day hyperlapse lessons.

Two reviews: Jonathan's tent hyperlapse video, Marcus's snowy temple video

'This whole sequence here, the sky needs to be masked out.'

Jonathan (Elk Lake, family gathering, waypoint hyperlapse of a tent going up): praised the twisting pull-up opener, soundtrack, sunflower colours, the waypoint arc; top note, repeated - mask and darken the sky; cut earlier on the beat; trim static starts and over-runs; no jump cuts; pick a subject (centre the gazebo in the orbit); intentional jump cuts to compress the tent rise; Final Cut is fine, don't round-trip to Resolve for colour. Marcus (snowy mountain temple): dynamic opener, 3x shot, a 'killer' low push-in tilt-up; title font too 'old camera', nudge the Scope crop down so peaks aren't cut; jump cuts; start the ramp earlier and cut on a beat after; recentre the temple in the orbit; are the snowflakes real?; sky mask for cloud texture; stabilise the tilt-up reveal; AI narration over on-screen text for retention.

Why it matters

Sky masking arrives as the single highest-leverage note - principle two, live.

Flying in snow: fine; fog near freezing and whiteouts are the risks

'My personal experience - I don't know if this is recommended - go for it.'

He has flown in heavier snow than his clip showed with no issue - it 'flies around the drone.' Cautions: whiteout is below legal visibility and hides manned aircraft; fog or mist right at freezing ices prop tips (max-power warnings, never a crash). Course platform migrating within a month with a built-in community replacing MeWe; Q&As to go twice-monthly.

Why it matters

A practical answer with the two real hazards named.
