Questions about filming a school play with XT2

[stephen young]

I've been asked to film a school play. Probably max 2 hours with a break in the middle.

Last time I did it (same school) I had a video camera. Which I've now sold.

 

Now I will be using the XT2 plus an XT1, Both on latest firmware, both with battery grips and both with Rode external mics.

 

I know that due to video time restrictions I'll need to keep switching between cameras.

 

My plan is to set 1080 24fps and  ISO 800 on both cameras. Then play with the aperture to get as much in focus as possible.

 

I thought to have the XT2 connected (via the battery grip) to the charger.

I believe this will power the camera but not charge the batteries.

 

This will be my main camera.

 

As the XT2 gets close to max video clip length (29 minutes) I intend to turn on the XT1 (max 15 minutes)

 

Turn off the XT2 and let it write the data to the card, then turn it back on and turn off the XT1

 

This way I have no blank spots (although it obviously makes more work in editing)

 

My questions are as follows:

How much filming can I get on a 64 gig card (I'm not intending doing 4k)

If the mains charger connection isn't advisable/workable how much filming can I get out of the three batteries in the XT2 and the two batteries in the XT1

 

Sorry for what may seem simple questions, but as I've only had the XT2 for 2 months and the XT1 even less, I thought better to ask than spend wasted hours with trial and error.

 

 

Thanks in advance

Steve
