View Full Version : 30f on canon - 30 drop or non-drop?

I am trying to figure out how to edit some footage. Some was shot 30f on the canon camera, the other footage I assume is 29.97 from a Sony DCR-HC96. I have them both in one project and they look fine, but I am wondering should they be edited in separate projects with different settings? Technology has changed and adapted so much in the last few years that I`m not sure I have to tread as careful as I once had. Some insight would be helpful

Thanks

I do everything drop frame. I don't know this for certain, but my guess is that the Canon's 30f is really 29.97. I should know this since I have three of them, but I don't.

My logic works this way. We're in NTSC-land. The NTSC standard is 29.97, so to conform to that standard everything has to be acquired at that frame rate.

Yes, frame mode 30F on the XL and XH cameras is 29.97 fps. The actual frame rate of 29.97 doesn't change with drop frame vs NDF. The frames are only COUNTED (labeled) differently -- with drop frame dropping a COUNT (not a frame) every so often to keep the display of timecode in sync with real time. With NDF the displayed timecode will gradually lag compared to DF and a realtime clock (hope I don't have that bassackwards). It is kind of a daylight savings time "spring ahead" sort of thing...no time is gained or lost and no frames are gained or lost, you just label the frames differently.

I think that except for 24F in SD (which is NDF by default), the XL cameras default to DF. If your NLE plays the 30F properly, I doubt there's anything to worry about for your editing.
