HI guys.
Have not been around here lately but thought you might like to see some highlights from a trip I did last year up to PNG and into Cenderawasih Bay on board the True North.
Anyhow, I used EDIUS 6.5 and cut the Raw Canon 1920/1080 25p H.264 with Protune GoPro2 with underwater 1440/1080 HDV (Amphibico Phenom - FX1) together in a 1920/1080 25p timeline.
Editing the 8 bit footage in 10 bit mode really made it possible to bring out the underwater stuff.
