Start timecode in Premiere not matching with FCP and Media info

Hi All,

We are trying to recreate markers created in our application to assets in premiere using our panel.

For normal videos this recreation is working fine.

We are facing an issue while recreating the markers in premiere when there is a non zero offset time code for a video.

When there is a non zero offset time code for a video, the start timecode value we are getting in our system (using mediainfo) is different from that in Premiere pro.

We have checked the file in FCP also and found out that the FCP and Mediainfo time codes are matching.

Media info

Time code of first frame                 : 07:22:37:00

FCP

Time code of first frame                 : 07:22:37:00

Premiere_offset_wrong_2.png

Premiere pro

Time code of first frame                 : 07:22:10:11

Premiere_offset_wrong_1.PNG

Is it a bug in Premiere? Or do we need to do some preference changes?

Here are the details from mediainfo,

Hi Anoop,

my guess is Premiere does a different frame rate interpretation from MediaInfo and FCP. If you look at the "frame rate" info in MediaInfo, it's 23.976/1000, which could be the root cause of the issue because it indicates NDF (non-drop-frame time code). Usually 23.976 is displayed as 24.000/1001 (DF, drop frame timecode).

The question is if changing the clip's time code settings (changing from 23.976 interpretation to 24, or vice versa) has any effect, because it doesn't tell you precisel

The question is if changing the clip's time code settings (changing from 23.976 interpretation to 24, or vice versa) has any effect, because it doesn't tell you precisely about the frame rate and its divider being applied in order to calculate time code.

Edit: Just performed a quick check here with some footage I set to your source TC at 24fps in Premiere, then switched from 24 to 23.976, and then I have the same value as you do in Premiere. So changing the TC display back to 24 fps should do the trick (Modify Clip/Time code...)

Best,

Erik

Hi Erik,

Changing the frame rate to 24, is making the timecode match with that of FCP and mediainfo.

Thank you for your quick update.

Thanks and Regards,
