my post was made in the understanding that you have recorded synced sound from your camera at 30fps. the 1% slowdown would not only keep the original in sync, it would also sync to the rest of your final edit and have the added bonus of matching framerates.
Like I said before, either you slow down BOTH at the same time using AE’s timestretch or cinema tool’s conform, or you use optical flow plugins like compressor or twixtor to conform to 29.97.
You may have put a lot of time into the pro tools edit, so compressor or twixtor may be less painful than replacing all the tracks by hand although the rendering time will be very high. I say the time to go either direction is about the same, ironic huh?
