Thank you all for your help. I own one 5d mark iii and have access to another one, so I plan on having a two camera shoot. That way I can cover the camera that needs to be restarted. I have done some trial runs and it works rather well. There is no problem with over heating. There is also an intermission that will allow us to change cards etc.
My main problem is what to shoot the video in. With the video about 165 min. my choices are limited. Here are my 5d mark lll choices of format
1) 1920 x 1080 24 and 30 frames
2) 1280 x 720 60 frames
3) 640 x 480 30 frames
I need to deliver the product on a dvd/bluray disk.
I do not want to us 640 x 480.
Can I shoot in 1920 x 1080 and deliver that or is it better to convert to 720?
Should I shoot in 720 (1280 x 720) 60 frames and how would that work at normal speed.
Sorry I am very confused and would take any suggestions you all may have.
Thanks
John
