Okay, great. You're already using an awesome DSLR camera for video. That was the first step. Oftentimes people try to get that crisp professional video feel with lousy cameras. Even if they're using DSLRs, they're sometimes so old that the technology simply isn't there. Although, I will tell you that you can get some incredible video from cameras that date all the way back to Canon's T2i. This entire line by Canon is very good.
Lenses & Auto Focus
Here's my first tip for you. Because some of the lenses that aren't silent can be quite loud when auto focusing in the actual video, you'll want to pick yourself up one of the silent ones. For Canon, these are called STM lenses which include the
Stepper Motor Technology. These are great for shooting video because they're virtually silent. I was actually taking lots of video just yesterday and I only heard the auto focus motor in the camera once while playing the video back. And even then, it was only a whisper. And FYI, I was using the Canon pancake 24mm prime lens. You can find that here:

Manual & Auto Mode
I don't want to discourage you from whipping out your camera to take some great footage in auto mode. We all do that and there's nothing wrong with it. The camera will figure out the best settings for you and you'll most likely love what you get. If you want more control though, I encourage you to try manual mode.
All you need to do to set manual mode is to turn your camera to the video setting up near the on/off switch and then turn the dial on top of the camera to
M. That's it.
Frame Rate
Let's talk about frame rate for a moment. What kind of video would you like to take? If you want HD video, you can choose 30fps. If you want to take HD video, but then add some elements of slow motion in your post-processing, go with the 60fps setting. If you want a film look, check out the 24fps setting. To set the frame rate, make sure your camera is in manual mode and then press the
Q button on the camera's back. Then, on the left side of the LCD screen, you'll see a small box with the current frame rate setting in it. Go ahead and touch that with your finger. I think it's the second box down on the left. When you touch it with your finger, you'll see that a few options appear down at the bottom of the screen. For me, I like to shoot with 60fps because I like many options come post-processing time. I'll press the 59fps box at the bottom. You can choose whatever you like though. When finished, just press the
Q button again and your setting will be saved.
Shutter Speed
Okay, this is where most people get confused. Shutter speed for video? Yes. I know, back in the beginning, I didn't even know video used shutter speed. Live and learn. There's a simple rule to follow though when you're shooting video in manual mode. Here it is: whatever your frame rate, just double that for your shutter speed. So if you have a 30fps frame rate, go with a shutter speed of 60. And for me, since I'm using the 60fps frame rate, I'll chose a shutter speed of 125, since that's as close as I can get to double. There's no 120 option. To change this setting, simply tough the shutter speed box on the LCD screen and roll the dial on the top of the camera.
Aperture
This setting will depend on how much light you have available and how much blur you want in your video. If you've got lots of light because you're shooting outside or something, then you can increase the number of your aperture (shrink the hole in your lens) without a problem. You can see how bright or dim your video will be right on the back of your camera as you're changing this setting. If you want lots of background blur in your shots though, open the aperture up all the way (lower the number). Just like shutter speed, you can make these settings by touching the LCD screen on the back of the camera. You don't need to press the Q button for these. They're right there on the bottom row on the screen. The reasons for setting aperture for video are exactly the same as setting aperture for photography. It has to do with light and blur.
ISO
For 99% of the cases, I see no reason to change the ISO setting to anything other than
auto for video. The only time I'd suggest that you set this to something stable is if you're in a controlled environment. Say you're taking video of a dark concert. You wouldn't want your ISO to be changing automatically, changing the lighting of your final video, so you'd lock it in to a determined value. If you're in a controlled lighting studio, set this to something predetermined as well. But if you're out doing some vlogging on the streets, keep it on auto. Let the camera figure out the best setting.
White Balance
Again, for 99% of people out there taking video, I would suggest that you keep the white balance set to
auto. Let the camera do the work. Really, if you're so into videography that you need to set a custom white balance for your scenes, you probably have a camera that's much more expensive than the T7i, not that this isn't an incredibly awesome camera. If you are in a tricky situation though, such as an environment that has mixed lighting or if the camera, for some reason, can't seem to get the white balance right, go ahead and set a custom one. I'll be writing a post shortly that will cover exactly how to set a custom white balance for video on Canon cameras.
Auto Focus
This setting trips people up a lot too. I was outside taking video yesterday of a drone flying around in the air above me and I noticed that my camera wasn't focusing on it properly quite a bit. There was a lot going on in the scenes and the camera had no idea what to focus on. I had my camera set to
Live 1-point AF. If I had it set to
Smooth zone AF, I could have just touched the back screen to set the focus directly on the object in question. It's a much more manual type of auto focus option, if need be, than the other one I just mentioned. And when I don't want to choose what to focus on, I can just keep the white focus square in the middle of the screen. To learn more about smooth mode AF,

There's a lot more to discuss when it comes to shooting video, but I'll save those conversations for those who are curious about such things. Things like camera stabilization, where to place your subjects, audio and external microphones, and bokeh. Taking video is tons of fun and once you get a handle on what your Canon T7i camera can do, you'll be off to the races. Let me know if you need any more answers. I'd love to help!
