In a single camera situation, I shoot both the stage show and the audience without stopping the camera, panning to an fro. but I do not want to include the pan in the video. Is there any alternative ways other than using cutaways ?
If that's the case, maybe you do do the following:
In the event there is little or no movement in the audience shot, simply extend that clip to the lenght needed (the clip plus the lenght of the pan) and add the audio from the pan under it. Does that make any sense?
Seems like you may need to grab some of that 'b-roll' stuff and put it on another track - or separate it frmo the audio. While you don't want the pan in the final, you do want the audio. The audio track is your mainstay...if you have footage that isn't of the musicians playing the music it will be hard to tell you're using video that's out of time. You may have to sync up some head bobbing but other than that it should be easy!
Another trick to try is to use Pan/Crop once in a while to flip the cutaway video horizontally (so it’s viewed backwards but playing forwards) so that it appears like you had a second camera shooting from another angle. Obviously this I not good if there are signs with words in the shot or even a shot of three guitar players on stage because the words or their guitars will now be backward, but if you have a shot of the audience or a tight shot of someone singing, you can get away with this trick. This helps the production because it varies the camera angle so that everything doesn’t look like it was shot with only one camera.
I suggest the solution lies in the shoot and not on fixing it in post. First option is use a 2nd camera w/operator concentrating on the audience while you get the performance. Another idea is to do the shoot over two performances, one focused on show, the other on the audience. Either way, with a bit of planning you can look like you have a lot of cameras.
You could pan the camera over the audience during applauses and these could be used at other times both backward and forward and slo-mo to make them look slightly different. Pan twice and you could have up to 8 different shots to add later. HTH.
Sometimes the lights go down early and this time can be used to video the audience.
