Chapter 4 Adjustments and Settings for Recording VFR (variable frame rate) time code • In 24PN mode, recording is performed at 24-frame time code, and output is performed at 30-frame time code to match the 2:3 pull-down scheme used for video output. • At a frame rate (capture frame rate) of 24P in 24PN mode, the speed of recording and the output time code matches actual time, but not at any speed other than 24P. (Example: at 60P recording progresses at 60/24 speed) • Then the camera operates in Rec Run mode and the time code output at start of recording matches the recording time code. • This is true also for frame rates other than 30P capture in 30PN mode and 25P capture in 25PN mode. 24PN recording at 60P capture Video output Rec start 0 1 2 3 Output time code 00:00 00:00 00:00 00:01 Recorded video 0 1 2 3 Recorded time code 00:00 00:01 00:02 00:03 25PN recording at 50P capture 22 23 24 25 00:11 00:12 22 23 24 25 00:22 00:23 01:00 01:01 Rec stop 58 59 60 61 62 63 Rec start 67 68 00:29 01:00 01:01 02:20 02:20 Skips 58 59 60 61 62 63 24/30 conversion 67 68 02:10 02:11 02:12 02:13 02:14 02:15 02:16 02:16 02:17 Rec start Video output 0123 Output time code 00:00 00:00 00:01 Recorded video 0123 Recorded time code 00:00 00:01 00:02 00:03 22 23 24 25 00:11 00:12 22 23 24 25 00:22 00:23 00:24 01:00 30PN recording at 15P capture Rec stop 48 49 50 51 52 53 00:24 01:00 01:01 02:04 Skips 48 49 50 51 52 53 01:23 01:24 02:00 02:01 02:02 02:03 02:04 Rec start 57 58 02:04 57 58 02:04 02:05 Video output Rec start 0 0 0 0 1 1 1 1 Output time code 00:00 00:00 00:01 00:02 00:03 Recorded video 0 1 Recorded time code 00:00 00:01 25PN recording at 15P capture Rec stop 14 14 14 14 15 15 15 15 00:28 14 00:29 01:00 00:16 Skips 15 00:14 00:15 00:16 Rec start 20 20 20 20 21 21 00:16 00:17 21 00:16 Rec start Video output Output time code 00 00:00 00:00 Recorded video 0 Recorded time code 00:00 0111 00:01 00:02 1 00:03 12 00:03 2 00:02 Rec stop 13 13 13 14 14 14 15 15 00:22 13 00:23 14 00:24 01:01 00:16 Skips 15 00:13 00:14 00:15 00:16 Rec start 19 19 19 19 20 20 20 21 21 00:16 00:16 00:17 00:18 20 21 00:16 00:17 70

• At a frame rate (capture frame rate) of 24P in 24PN mode, the speed of recording and the output time code matches

• Then the camera operates in Rec Run mode and the time code output at start of recording matches the recording time

• This is true also for frame rates other than 30P capture in 30PN mode and 25P capture in 25PN mode.
