Sounds good. Thanks.
On further thinking, tho, I should also ask if this is the best way to combine the product of these two cameras?
I'm actually borrowing a friend's 170 and in doing some testing I did some side-by-sides, out-putted that from a timeline for playing through iTunes on my (Apple) TV. The 170's 1080 footage was inCREDibly...gosh, what's the word?...interlace-y. Just shooting a person a la interview-situation and capturing their minor side-to-side motion while seatred resulted in a strangely high degree of horizontal video scan lines. Ergo I figured it best to keep the 170 at 720 to utilize the native progressive (and the 7D only shoots 24P in 1080).
