Back when there was basically one major digital format, DV, being used for everything from a little single chip homecamera all the way up toprofessional DVCPRO and DVCAM field cameras it was easy to calculate space. One hour equaled 13gb on your hard drive.
But today, there are dozens of HD file formats and each one is a little bit different. The Canon 550d uses an H.264 .mov file type.I have a T3i (600d) and used it to shoot a commercial on a single 16gb card. I shot a couple of hours of video total at 720p 60 and had room to spare.
I also have a Canon Vixia that shoots AVCHD and that same 16gb card has gotten me through weddings plus the reception with ease. But again, I’m comparing oranges to tangerines. The files are similar but not the same.
I would recommend you set up your camera and hit record for 10 minutes. Figure out how big the file is and do the math.
Since you’re getting paid for this gig – put some of that money into a handful of 16gb class 10cards. I use Transcend cards purchased off of Amazon and have had no trouble with them. They are extremely affordable.
Also, come up with a data management plan that includes backup storage. LikeEarlC suggested, don’t put all your proverbial eggs in one basket or you might find yourself with no eggs at all. I always have two copies of my video.
Finally, do remember the individual file size limitations on the HDSLRs. You don’t want to find yourself in the middle of the best soundbite of the day when you hit the 12 minute mark.
