720p60 to p30
After recording 720P 59.94, is there a way to change it to 720P 29.97? In other words can you change the tag that tells the capture software which frames to ignore?

I shoot this way alot. I use After Effects to convert it to an interlaced image because I find that it is cleaner in creating a 30i. If you want to create a 30p this can also be done in AE. Just create a 720p 29.97 timeline in AE and then drop your 60 footage into it. AE is a time based program not frame based. So if you insert a 60p into a 30p timeline it will by nature skip every other frame. When you render out if you select feilds then it will take advantage or the 60 frames and correctly interlace that footage, other wise you will create a a 30p version that skips every other one.

To piggy back on this discussion, if you dont’ mind: What if one wants to work in FCP–and what if you have 60p footage like Tom does and a 30 p timeline–anyway to get the 60p footage to play every frame and play in slo-mo at 50 percent speed? (that is, in effect, use 60p footage as 60 fps slow-mo footage)?

You know that is a good question. I know After Effects is smart enough that if you did want to do that you can use the speed adjustment and it would use the extra footage that was being skipped to slow-mo that footage. I guess you could try that same thing by adding a spped effect in FCP but I don;t know off the top of my head if it is smart enough to see the extra frames. It might take the frames like 2-4-6-8 since it is a 60p into a 30p and just try one of it’s blending methods. It would be nice to see if it is as smart as After Effects which would make use of the extra footage to slow-mo it.
