Hi all. I will be doing a 3 or 4 camera project soon. I have two Canon tapeless AVCHD cameras, a Vixia HFM43 and an HFG10. I'm going to borrow two more cameras but don't know what kind they are yet. I was thinking of shooting the HFM43 in Canon's FXP mode with a 30 frame rate, and the HFG10 also in FXP mode but with a true 24 fps progressive, a frame rate that the other Canon is not capable of. I wanted the better frame rate because I am sometimes going to crop and zoom in on parts of the video taken with that camera, and the higher quality video it takes seems to make this possible without making the video too grainy. I have since googled a bit on mixing frame rates like this in one project, and people generally warn against it. Is this true? Is it better to stick to one frame rate?
Life will always be easier and quality higher if frame rates match.
Mixing them should only be done in dire emergency when there is no alternative.
If you put a 24p clip in a 30p sequence (or vice versa), it will have to be converted, which involves a very lengthy rendering process and the motion quality is never the same.
On the other hand, Conforming the video does not reduce any quality, but it slightly slows down or speeds up the video according to which way you are doing it.
