First are you recording at 1920x1080/50p? (or 60p if you are in the Colonies) I tend to leave the settings at IA unless I am forced to go Manual. Really you will need to experiment with the Picture Adjust or try the various pre-sets for portrait, fireworks etc.
Finally you don't say what you are filming. If the subject matter is dark then the video amplifiers will kick in and a grainy picture will result.
I should explain I am not an expert on the 720, I have just moved from the brilliant little V700 to its new grandson the V750. So good luck with the "Dad".
Hi there I've had this fine camera for almost a week and I'm getting used to it... I did my first video test and the picture was fine... I thought it was abit "grainy" if you get what I mean... I used the manual settings still the picture was not what it seemed.
Today I did another test and noticed in the "Record Setup" in the menu there is a "Picture Adjust" i.e Sharpness, Color, Exposure and WB Adjust....
I whacked the color upto the top and I noticed a huge improvement,
My question is what should I do with the other settings should I crank them for more performance and what do you recommend?
