The focusing system is different for live you and movie than it is for standard picture taking and it has to do with the fact that when you are in the live ur movie mode the mere in the camera is no longer in its normal position mir is a partially silvered mirror which allows the camera have a little bit of light through that mirror and bounced down to an auto focus sensor so when you're using this camera in its normal mode it's getting good autofocus information all the time when you put it into the live you or the movie mode this mere goes up the shutter opens up like come straight into the sensor and at this point the autofocus sensor is not doing any good so it's looking at information on the sensor and the censor is just trying to judge based off of contrast how in focus the subject iss and you'll notice on our examples here in the class the cameras a little slow to focus and that's because this system is not the fanciest best system in the world if this was important to you, the ...
next step up in the can in line up the seventy d and the seven d mark too offer and improved focusing system that uses a different type of sensor that is able to focus much faster and follow action much more smoothly. But on this camera it's going to be a little bit slower now when it comes to shooting movies, we have three different resolutions that this camera can shoot at. We have full hd, which is nineteen twenty by ten eighty, and pixels standard h d as well, it's just a standard definition if you're looking for a smaller online type video that needs to be very small and compact and file size, and so we'll be able to make choices in the camera about what size we want. Now, while we're shooting movies and our cameras in the movie mode, there is a continuous autofocus that our camera has turned on and let's, go ahead and take our camera, and we're going to put this in the movie mode, and so the movie mode is up here on the top left, so we're going to switch this over into the movies. It automatically turns the screen on and so it's not shooting movies yet that is done by the red button got always look for the red button when you're going to shoot videos, but we're gonna put a little object out here in front of the camera a little bit and you'll see how this camera in this movie mode let's make sure that we've I got this turned on. And let me make sure that we're in I'm not going to do face detection I want to do point area small bracket and so now as I point the camera at different subjects I'm not pressing the camera two focus I'm not touching the screen to focus its in continuous focus and the reason it's here it's because we were in the movie mode but by pressing the flash button over here on the side of the camera right here I'm going to press that button and watch what happens let's see horseman subject here when I press this button and you see how that got gray the box went gray and so now it will not re focus I'm going to release my finger and oh it's stayed locked in okay, so let's lock this off not what I wanted okay? So if we press this the cameras are automatically refocusing just by pointing the camera to a new location this is in the movie mode if I said no locket there I could come up here to the flash button and I'm going to lock that in and so that button is a dual purpose button it knows that when you're shooting movies you're not going to be using flash so I'm going to press the button again to release that focusing and so now it will focus and we'll lock it in and you could actually see down here in the lower left corner, it lets us know whether that's active for focusing, or whether it's locked in. So when it's locked in that green light goes off. And so if you do shoot movies and you are continuously focusing that it's a way for you to hold the focus on a subject while other things, maybe moving in and around it. Which is kind of a neat feature that not a lot of cameras have. All right. So back on the keynote, we're talking about movie stuff. So the files that you get from this are fairly basic video files in the world of video. And so they're just going to be in p four files that are very common. You're going to have to work with them very easily. On most all computers, we have three different resolutions that we can choose from. Generally, we're going to choose the highest for most of our videos, I would imagine. We have different frames per second depending on the type of look and the type of video that were trying to record and there is two different compression standards when we shoot video it compresses this massive amount of data into a file and how much compression we do has ryan an impact on what the final product is going to look like some cases image quality is paramount in other cases spaces paramount we want to compress things to have him in the smallest package possible so we'll be able to see that choice when we get into the settings for making these in the menu settings and finally we have different file sizes that is the maximum final of the maximum file size on this camera is four gigs if you shoot more than four gigs what happens is the camera packages that as one file and starts another file so you don't need to stop recording or restart recording the camera will just package those videos as two independent files there is a limit has to do with the parameters of the card. The other issue is that the camera cannot record for more than thirty minutes of recording if you do need to go longer than thirty minutes, you're going to need to restart recording again you can record for twenty nine minutes fifty nine seconds and then do it again you just need to restart recording now any time the camera is in a movie mode. You can press the shutter release and taking take a still photo. This is, after all, primarily a still photography camera. And so they want to allow you to be able to do that. However, you will be restricted to the fact that it is a sixteen by nine aspect ratio when you shoot it, which is thie hd aspect ratio. Okay, so that is the live view and movie shooting modes of the camera.
