"5 ways to save on groceries" and "How to repot a plant in 6 steps" are lists, and lists make good short videos: each item gets a moment on screen, a progress bar shows how many are left, and the viewer stays to the end to see them all.
Type a title, your items one per line and a closing line. Each item becomes a card with its number and a progress bar across the top. Choose numbers or "Step 1, Step 2", the time per item, a font and a color style. The video is encoded in your browser as an H.264 MP4 and nothing is uploaded.
Writing items that fit a card
Each card is on screen for a few seconds, so write for a glance: eight words or fewer, starting with the action. "Freeze bread on sale" beats "You might consider freezing bread when it is discounted". Three seconds per item is comfortable for one line; use four for two lines.
End with a closing card that says where the full version is, such as your blog. The link itself goes in the pin, not in the video.
Tips, steps and recipes
Use numbers for tips and ideas, where order does not matter, and "Step" for instructions and recipes, where it does. A recipe works as a title card, the ingredients as items, or the method as steps.
For a still pin of the same list, use the step by step pin maker or the checklist pin maker. To split a list post into several pins, use listicle to pin series.
