A complete pass with the decisions that matter
1. Decide the destination, then the stills
Instagram feed: 1:1 or 4:5, ten frames or fewer. LinkedIn document: 1:1 stills plus a PDF hop. Facebook organic or ads: usually 1:1. Product walk: hero → detail → lifestyle. Lesson: one beat per frame. Gather those files. Convert HEIC. Do not start with a 40-photo dump and hope the strip edits itself — it will not. Two photos is the studio minimum; more than sixteen will not load.
2. Filmstrip controls
Open the hub, switch Single → Carousel. Set ratio. Set slide count to the number of full-frame beats (not “a few extra empty ones”). Add files. Dashed guides (export-hidden) show cuts. Drag inside each pane so the subject survives object-fit cover. Background hex only matters if gap/padding shows. Corner radius is optional cosmetics. There is no grid catalog in this mode — if you wanted cells, you wanted collage.
3. ZIP, order, extra hops
Save All. Unzip. Sort by name (slide-01…). Upload in that order. Instagram: attach as a multi-image post. Facebook: same, or import into Ads Manager. LinkedIn document: impose PDF (Preview / Drive / Acrobat), then upload. Add type in the destination or in a kit before you drop PNGs in. If a frame is soft, the source was small or the pan left the subject on a seam. If Safari vanished, you hit RAM — see the mobile spoke.
