I have searched high and low for a simple explanation of the implications of editing and Aspect Ratio.
I understood that if you shoot in 4:3 you should edit in 4:3 and similarly for 16:9.
1. Can you mix the ratios in a video? - would it then produce a video in the ratio you have chosen when setting up the project in the first place?
2. If the software will deal with both then what is the effect on the quality of the ratio when changed by the editing software?
3. Can you edit in one ratio and save in the other? What is the quality effect in this case?
Alternatively can anyone point me in the direction of information on the internet that would adequately explain the whole concept?
