Mixed 24 and 60FPS Proxies
I have a project that is going to be 24p. Most was shot at 24p. Some was shot at 60p for slo mo (although some will not be slowed.) Some was also shot at 30p. I have to make proxies because I’ll be on the road a couple weeks and my laptop can’t handle the native files for multicam sequences. Do I need to make separate 60p ingestions or do I proxy them at 24p? Do I need to do anything particular to the 30p proxies?
Thanks.

Well, in case anyone runs into this transcode different frame rates with their original fps settings when making proxies.

Always keep the same frame rates in proxies. Just the quality of the data in the images used for frames will be different. That said, if you plan on speeding or slowing video, you want to work with the original frame rate. 60 drops to 24 easily. 60 drops to 30 easily. 30 Drops to 24 easily. Vice versa. For 60->24, it’s 40% exactly (even in drop frame). For 30->24 it’s 80%. For vice versa, 24->30 is +25% (so 125% to speed up). For 24->60 it’s +150% (set to 250% to speed up).
