Lessons learned from VG3:
1. GET DONE BY THE DEADLINE AND DO NOT PUSH IT
2. If one of the editors is in a bad situation and has not started yet (like 1 day before the deadline), kick him/her out. Do not let them begin capturing their footage 1 hour before the deadline -_-;;... unless it's a very important track... then you're screwed.
3. If you want the project shown at a con, always test it out on a tv via tv out card/mpeg2 card/authored dvd to see title safe areas, interlacing, and field orders.
4. Be prepared to fix any and every problem. An editor gets you a good video the day of the deadline and barely has time to fix it since he/she is going away for a few days/weeks later and it has small field order and audio problems and is a very important video to the project... make sure you know how to fix those.
5. Make sure you prepare materials for editors if needed. Not every editor will have access to stuff you need for the project.
6. Keep in good contact terms with the editors. Harassing them every minute of the day is annoying but when the deadline is looming near, it's more acceptable.
7. Make sure your editors adhere to the quality standards of the project. Don't be afraid to give and take constructive criticism and suggestions. You don't want one bad video in a group of very good ones. Push your editors to make the best tracks they can make.
8. Only hire people you feel are trustworthy for the project. Make sure you look at their past videos to see if they will provide good work for your project.
9. Set a reasonable deadline allowing time to fix problems that happen after. Make sure this goes with rule #1
