Thanks Lew. You are always on it!! I did some more checking on this camera and found that the underlying MP4 compression is h.264 - RATS.
However, I did find a couple of file-based dslr cameras that should work given the HD file formats they record. Namely the Pentax K-5 II and the Samsung Galaxy NX. Both get relatively good reviews. I tried sample footage from the Pentax on a Liquid timeline and it worked great - imported with gray slices! Now I'm looking for some sample footage taken with the Galaxy NX. If I find some, I will post on how it works with Liquid.
