Quality", "I Frame Inter.", "Stream Type", and "FrameRate" are changed in the middle of recording, recording will stop andthen will resume. Then the setting values become effective.If recording is not stopped, the new setting becomes effective after thelapse of the time period preset with "RECORD LENGTH".Playback is delayed if the setting value for "I Frame Inter." is too high.
