I’ve been using 10 seconds for a long time. The other advantage of a larger interval is that they generate faster, too.
Some clients - like Roku - have a minimum scrub distance of 10 seconds, so it doesn’t hurt the experience much at all. Apple devices have a smaller minimum scrub distance, but 10 seconds still feels “pretty good” to me.
@FordGuy61 - that math is good in theory but I don’t think the savings are quite that large in practice. I think there’s some interaction with keyframes but I haven’t looked closely or recently.
These were the actual results from a movie back when I did look:
| setting | size | savings |
|---|---|---|
| 2 | 30 MB | original |
| 5 | 19 MB | 37% |
| 10 | 11 MB | 63% |
