” I very much doubt that the “H” setup cards are transferable, there are many functions that are unique to the Varicam that would only corrupt the HVX900 (Dynamic level, frame rate, Film Rec, Video Rec, etc.)”
John is correct. Varicam files will read as errors on the HDX900. However, you can customize and save your settings on 1 of the 8 scene files. This will eliminate the need to carry 2 cards if you will be using the varicam and then switching to HDX900.
