Looking for real world times on record length and battery life for a T4i. I'm doing a 3-5 hour seminar and have to have the camera rolling the whole time. I just ordered a battery/grip unit and a couple 32GB Sony class 10's. Does anyone know how long each card might last? And typically how long a battery will last with and without the LCD showing? Thanks in advance..
Recording time for 32GB cards in a T4i?

your going to have to keep pressing record after 12 minutes, you should have enough for a 5 hour shoot, but with one battery your really pushing it, why didnt you buy cheap chinese ones? i have 4 chinese ones and they will last me the whole day
For the T4i, I think it's 29 minute segments with auto restart... They were the cheapest ones on Amazon, $20 ea. I also have 3 batteries and ordered 2 more. Just wanting to time the card/battery changes so I know when to flag the mobile camera guy over to record while I swap out, otherwise he floats around getting audience shots and alternate angles of the speaker.
It's about 16gb per hour, so 32gb is roughly 2 hours.
That's at 1080p 23.976fps. If I remember right 720p 60 is about the same?

Also, even if your limit is 30 minutes it's good to play it safe and stop/start (with cover obviously) as often as possible. We do live event with 12-minute length DSLRs all the time and usually cover every 5-7 minutes.
Watch the battery too. If it runs out in the middle of a take, you'll lose the take! Another argument for shorter stop/starts. If the battery dies 29 minutes into a take you'll lose it all. Losing 5 minutes because of that still sucks, but not as bad!

Thanks Paul. It's a 2 hour live seminar with pre and post event coverage, so I gotta run at minimum 2 hours of non-stop. I then have to edit the individual segments separately so will problly try to follow that schedule for battery and memory swaps.
t4i has a limit of just over 29 minutes / 4gig, so this depends on what resolution you shoot at. For instance 1080p is in the 320-330mb/min range so that'll let you shoot for about 12 to 13 minutes at a time.
Lower the resolution and you can get it shooting towards the 29 minute limit. There is no way with a t4i to shoot for 2 hours.
If you need to shoot continuously for 2 hours, you'll need a different camera.

Is that specific to the t4i? I've had the 5DmkII battery die while recording and it's never lost the take.
Thanks Sweetie. I don't need to have non-stop footage, just want to make sure the transitions line up with battery and memory swaps. Should be a very small pause between segments where I can use the 2nd camera to capture the speakers moving to their next topic while I swap out. I just want to make sure I have enough batteries and cards to make the full 2 hours plus an hour of before and after activities. Is the 4GB the max recording it will do before it makes a new clip? I should just run the thing through a couple batteries and cards to find out for sure, just thought I'd ask around first.
