In video, its important to keep the ratio of how much footage you shoot to how much footage you use as low as possible. This ratio is the biggest influencer on maintaining profit.
More footage means:
- more storage – Hard drives cost money
- more time searching – Time spent searching for the right shot costs you money
- more time loading or transcoding – Even fast machines still take a long while to transcode
I always recommend rehearsing your shot if possible, then firing a few takes. Be sure to cut camera between takes as well so you can have shorter clips. If you're using a slate, hold it up at the start of each shot (then you can clearly see it in the clip thumbnail, which speeds up browsing).
You need to remember time equals money. More time searching means less time editing. More time recorded means more backups and hard drives. Look out for your best interests and you'll see more profitability.
