I don't film much with my 5D, but am doing so more and more, interviews mostly.
Anyway, the other day at a party, some friends broke into spontaneous song. I already had my camera out and chose to film it. Fine the settings were far from perfect, but i shot it anyway as a memento. During filming, i took a photo, accidentally (alcohol induced snap-happy fingers). I thought nothing of it until i checked out my footage the next day, and felt both stupid and annoyed (ontop of a throbbing head). In the footage at the moment i took the still, there is a pause in the filming and an audible 'fake' (?) shutter click, before continuing normally. Fortunately, it was just friends and I think they will find it funny considering it was me, but also shoot b-roll and interviews on the side for a small documentary producer. Thankfully, nothing like this has happened in any of these jobs...
I knew it was possible to take stills while filming, but if it screws up the shoot, what's the point? Is there anyway of repairing this, or at the least disabling this feature so i don't do it again? What did i do wrong, and how can i avoid it in the future.
