Mixing HD Video formats in Vegas - Need your suggestions!

I recently purchased a Panasonic HMC-40. I shoot a lot of football and will be shooting video from the Panasonic using the 720/60p format. I like that format because it does a nice job with little blurring on the fast motion shots.

I need to purchase another (less inexpensive camera) that I can use for random game shots. These shots will be mixed into Vegas with the 720/ 60p video (I use Vegas 10). I can't find a camera in my price range (under $700) that shoots in the 720/60p format. So I'm looking for suggestions on what format would mix well with the 720/60p and give me the best quality. Most of my work will be put onto DVD, so keeping the HD format is not a major concern.

One camera I was looking at is the Panasonic HC-V700. It shoots in 1080/60p. Would this be a good fit?

Any thoughts or suggestions would be very much appreciated.

Thanks

Yup. I have a Panny TM700 as the "B" camera to my HMC-40.. it even uses the same battery standard (I have a cable to let me use the big cell on the TM700). The 1080p60 mixes just dandy with the 720p60 from the HMC-40.

The V700 is more of a mid-range model, and Panny changed the battery for their consumer models after the TM700, which seems arbitrary and annoying (the standard used on the TM700 and HMC-40 also worked on my daughter's SD-9, a camera I bought her used when she started "Communications Academy" in high school), but they have a number of great improvements on sensor sensitivity and "hybris" stabilization (optical for X/Y, digital for Z-roll... makes a ton of sense). Not a non-issue... if I have both cameras, I'm probably using both on tripods, or the HMC-40 on my Glidecam. But sometimes I just grab the TM700 alone, and then it's more likely to be a handheld thing. The OIS make that a useful thing to do.
