Starting with MC|AM 2023.7, the handling of timecodes around midnight is changed:
-
Up to MC|AM 2023.3, MC | AM keeps the SMPTE timecode labels in sync with the wall clock.
-
Starting with MC|AM 2023.7, MC | AM doesn’t keep the SMPTE timecode label in sync with the wall clock. Instead it counts to the last SMPTE timecode label that is below 24 hours and then resets to 00:00:00:00 or 00;00;00;00.
Non-drop-frame framerates
| Framerate | Up to MC | AM 2023.3 | MC | AM 2023.7 and higher |
|---|---|---|
MC | AM counts to the SMPTE timecode label of the last frame in the calendar day and then resets to 00:00:00:00. |
MC | AM continues counting up to the highest valid SMPTE timecode label and then resets to 00:00:00:00. |
