LiDAR Video and Bookmarks
LiDAR video, bookmarks, filming on a line, the Photos app.
LiDAR video: Main lens, unstabilized, so picture and depth line up.
A normal video plus a depth frame 10, 15 or 30 times a second (10 to start), each with the camera's position and a sharpness score, so you can pause anywhere and measure. Tap LiDAR (left end of the row) in Video, or pick Media, Video from the Drop Station menu to open straight in LiDAR video. LiDAR stays on when you switch between Photo and Video.
Settings (Media settings, LiDAR): 1920 x 1440 (to start) or 4K where your iPhone offers it; 30 or 60 fps (60 only at 1920 x 1440); 4K always records at 30 and drops to 1920 x 1440 if it gets no depth. It always uses the main lens, unstabilized, so the picture lines up with the depth. Recorded in HEVC.
Bookmarks: Find the important bits fast in a long clip.
While recording LiDAR video, the bookmark button right of the shutter marks a moment to come back to, with a count. When you measure the clip later, a button jumps to the next bookmark.
Filming during a Cave Line: Keeps the survey intact while the camera rolls.
With a line open you get LiDAR video from the survey's own camera, at 1920 x 1440 with no sound, and the line keeps tracking while you walk. Film from a station and, when you leave the camera, the line picks up with one straight leg and drops an end station where you stand, like a scan.
In the Photos app: Why a copy there can't be measured.
Save to Photos app gets the plain video; the depth stays in SpeleoMap. To pass on a LiDAR video someone can measure, share it from SpeleoMap.
