• Make a reel as long as your footage allows, with no fixed longest length. • The suggested length now comes from your best moments. • A long reel moves on to a new track when one ends, instead of playing it again. • Making a reel takes less memory and less time, 4K YouTube reels most of all. • Videos no longer in Photos leave their folder, and the reel is made from the rest.

• Make several reels of the same videos at once; each waits its turn in the queue. • Choose videos right in the folder and make a reel of just those. • The best moments get the most time: a great shot runs longer, weaker footage comes in only when nothing better is left, and a reel fills the length you ask for. • A finished reel opens first on its page, with Redo this reel to make it again at another length. • Night dives keep the torch's colour, and the dark stays dark. • Dives and reels arranged by month.

• Colour correction now decides from the footage itself: GoPro and other footage whose white balance couldn't keep up gets its red back and green water brought to blue. • Footage that already has its colour, from a camera that corrected it, a filter or a torch, is kept as it is and never corrected twice. So are reels made by Surface Interval on the phone or the Mac.

• "YouTube optimized output" for each reel: 4K and 10-bit, which YouTube keeps sharper. • Open water and sandy or grassy seabed keep a more natural colour. • Sharper reels, saved at a higher quality. • Vertical reels of any length. • Every reel fades out with the music. • A smaller download: 8 tracks built in, 45 more in Settings on iOS 26.4+. • Two reels a day are free; Week, Year or Lifetime lifts the limit and lets you turn the watermark off in Settings.
