Of all the video camera apps on the App Store, Filmakr in our humble opinion is the best video app.
The King of Video Camera Apps
Focus & Exposure:
(For tips on how to use the camera including manual focus and exposure: tap on the GEAR Button, then explore the hints and interactive tutorials there.)
Tap camera screen, focus slider appears on right & exposure stepper on left.
Focus: if tap&hold to set a mark, slider affects that. Set second mark, slider affects that & mark 1 is inactive dashed-circle.
Rack Focus: tap a mark, focus pulls to that mark & slider now controls that mark. Rack speed setting is under slider 1x 2x 3x
Tap anywhere else on screen to get auto focus (any marks become dashed/disabled) Double-tap focus marks to remove.
Make Exposure stepper appear: touch focus mark, slider or screen. If set exposure lock stepper does not fade off. Double-tap for auto.
Tap GEAR BUTTON > WB or EXPOSURE > CUSTOM. On camera screen, if tap Custom Exposure indicator Shutter/ISO controls show without having to tap through the GEAR etc. Double-tap for auto.
When a custom shutter set the only way to affect exposure is with ISO, so can even change ISO while recording.
