I am looking to make a music video from a number of live shows by getting fans to send in their clips taken at the shows. We run our timing from a backing drum track on Cubase, so that is fixed, which means this should work, however I have never tried to use that many inputs in different formats, with different light levels etc. I don't need to worry about sound from the devices - we can take that from house sound.
Are there any things I should plan for?
More generically - how do video producers cope with matching or normalising inputs from multiple differing devices?
