Thanks most kindly for the prompt answer. I have the Rebel T2i/550D. Since I bought it on 4/2010, I have used this fine camera in AV mode on a tripod exclusively for still shots for my website www.vintagetextile.com
I have yet to use Live Mode, though I will look into that tomorrow. I was able to make a short video today by pressing the movie button in movie mode. But whatever other focus settings I tried did not help in getting the video into focus.
"use the auto setting and tap the screen on my T6S to focus at a point if necessary"
Which auto setting?

The Rebel T2i is not able to Auto Focus while recording video. You must pre-focus before you start recording video. If you need to change the focus point while recording video, it must be done manually.

Thanks, Mike, that is just what I wanted to know. What is your recommendation for how to pre-focus on the subject, e.g., what mode to go into first and how to do it, since I have always used AF?

I would just AF in live view first and then switch to Video mode and start recording the video. You can also AF in Video mode before you start recording.
Using an aperture of f/8 or f/11 gives you more depth of field and keeps more of the scene in focus.

If you're shooting video in auto exposure mode you might want to consider using manual exposure if that's available on your camera.
If the camera is trying to shoot at wider apertures that's going to give shallow DOF and make it difficult to hold focus with changes in the distance to your subject. Try manually setting aperture to f5.6 or f8 to get more DOF. Depending on the lighting you may also have to adjust shutter speed and ISO rating as well.

Thanks for the excellent advice. I will experiment with this.
One issue I had today was trying to change f/stop from the standard f/8.0 that I use in my standard Av mode.
To change a setting such as f/stop, whether in whatever creative mode or in Live View, do I first have to go to Manual exposure? Is that a setting reached only by changing on the lens itself?
