Apple Final Cut Pro 7 Multi Cam Editing

I really need some help as I am running out of time to finnish this video. What happened is, I am an 8th grader at my school and for my EAST Initiative class I was chosen to film my schools play. On the first day, due to technical difficulties I was only able to film from one angle the next day I filmed from 3 angles but then one camera ended up malfunctioning and so now I have one angle from the first day and 2 angles from the second day. However everything seems to go faster on the second day i filmed to everything is off by about 3 seconds is some areas and off by 8 seconds in others and sometimes it is perfectly in sync . What should I do to fix this. I know that there must be a way because I have noticed that when I watch let's say comedy shows with multi angles I can see that when they switch angles the person is wearing different clothes because they filmed on two separate occasions. How do they do this because i dont think that the comedian is talking at the exact same speed every time. Please someone take the time to help me I would appreciate it so much!!! Whoever helps I will give credit to in the video if you want me to

Thanks, Trevor

You can not use Multicam editing for clips coming from different performances at different times. Simple, human performers do not move, speak, etc, in perfect timing in each performance. Multicam can not magically fix this.

Edit the first day's footge.

Then multicam the second day's footage.

Them manually combine them with copy and paste from the two original Sequences, into a new 3rd Sequence which will be your output Sequence.
