This regards video file size as created on my iPad. I took 6 or 7 short video's with a total time of about 3 minutes and a total size of about 950 MB. Why is the total file size so large of video only about 3 minutes in length?

"Raw" or unprocessed video needs a humongous file space. When compressed down to an MP4 or similar file, it might be only 15% or so as large. But the compression program may take away some subtle pleasures from the original. Better programs effect the least visual losses.
A 2.5 minute WAV audio file could be up to 30 megs in size.. but if converted to MP3, may only be 3 megs!
