Focus issues and video blown out issues

I have been using my T2I this week for a lot of video. Im having issues focusing. Would purchasing a viewfinder eyepiece like this one http://www.bhphotovide​o.com …F_3_2_LCD_ViewF​inder.html

Also, Im having problems regulating proper video levels in very bright outdoor settings and in darker indoor settings.

Can anyone give a quick link to tutorials?

An LCD viewfinder will indeed help you focus, especially in bright daylight. It was the first video accessory I bought, and I use it all the time. Working in a high f-stop range will also help with focusing, if you can tolerate its wide DOF. A follow focus might help, but it will only help you hit focus faster and easier. If you can't see what you're focusing on, a follow focus won't help. Better to get your technique down first, then add more gear as you need it. Speaking of which, PRACTICE PRACTICE PRACTICE.

For regulating exposure in bright light, you REALLY need to use a neutral density filter, either a variable NDF or a set of singles. Of course, NDFs won't help in low light - for that, you'll need a fast lens. There are lots of video tutorials on NDF on vimeo. Just do a search.

For exposure.. The histogram is everything! I don't think the T2i has a live histogram in video mode. You can download magic lantern to get one. You can also take a picture before shooting each scene, turn you highlight alert on, and check your exposure through the histogram and make adjustments that way before shooting.

For focus.. Like Snafoo said.. Start with a higher f/stop till you get the focusing down. If your shooting wide open, zoom in to get your initial focus prior to shooting.

+1. This has become so natural to me now that I forgot to think about it.
