Document Summary
1020x720 still hd, but smaller file size and less information. Frame rate: 24fps more cinematic, film look, 30fps more like tv, video/news look, 60fps sports. Need a constant light source custom white balance using white card. Must use light meter: screen/monitor can be deceptive, good for framing not for exposure. Iso to 400 okay: can push to absolute max of 800, 400 recommended, 250 iso in daylight, avoid low light situations. With video, can only shoot 8-10 minutes on 4gb (at 30 fps, h264) Do not use autofocus or auto-exposure: distracting to have exposure or focus shift mid shot. Put camera on manual settings: aim not to adjust focus mid shot, set your focus and exposure before you begin recording a shot. If necessary, must rack focus: measure distance from subject a to camera, measure distance from subject b to camera, mark distance on lens with tape, move from one to the other with a smooth movement.
