Markers off by 2 frames

[maximus1105]

After installing new PPro version, all the sequence markers and cuts, in my video sequence, are off by 2 frames.

Marker timings changed by 2 frames. Original Video Sequence is in 23.976 fps.

Not sure how to fix this.

Anybody can help?

Hello Kevin,

I had to write a ExtendScript to list and move all the marker positions by 2 frames right.  And I had to execute the script on all Sequences with markers.

Problem:

I made markers earlier in video sequences using PPro 12.0.0. (my videos are 23.976 fps)

For example:  I made markers at 00:00:00:00, 00:01:00:00, 00:02:00:00, 00:03:00:00, 00:04:00:00 etc.. representing cuts at shot boundaries or chapters in my Video.

Now, after upgrading the Software, to 12.0.1 or 12.0.2, the maker positions and timings REMAIN SAME.

BUT the markers are not showing the same video frames underneath as before.

The video frames under the markers are either OFF by 2 frames left or right.

FIX.

To solve this, I wrote a program to move all the markers by 2 frames, to fit into original frame positions.

QUESTIONS:

The main question is WHY ARE THE MARKERS OFF and not showing the same video frames as before.

Is there are simple solution to this?

How can the markers be correct and the frames different?

My test was useless, as I misread your post and was testing from 12.0.1 to 12.1.1. (I don't have 12.0.0 installed on any PC.) I created a sequence with a 23.976 sample with timecode effect and added markers. No difference, but as I said, I was not using the correct version.

To explain it with an example:

Lets say you have a sequence with various clips, each with a minute duration.

     00:00:00:00 - Apples

     00:01:00:00 - Oranges Clip Starts

     00:02:00:00 - Bananas  Clip Starts

     00:03:00:00 - Mangoes  Clip Starts

Place Sequence markers at exactly when each new clip starts in Sequence.

Now update the Software.

The markers still are at 00:00:00:00, 00:01:00:00, 00:02:00:00, 00:03:00:00. BUT

At 00:00:00:00 your are seeing Apples.

At marker 00:01:00:00 you are still seeing Apples,  unless you move 2 frames to 00:01:00:02 to see Oranges clip

At marker 00:02:00:00 you are still seeing Oranges,  unless you move 2 frames to to 00:02:00:02 to see Bananas clip etc..

What camera was used to record the footage?

[maximus1105]

Over the years, i used many cameras, Canon 5D, Sony, Red.etc.. producing clips at 720p or 1080p at 23.976 fps.

I guess Camera type has no bearing on this issue. The footage is basically 23.976.

If you are doing a test, you can download ANY video on YouTube, Vimeo with 23.976 fps  and test.

[excited_Genie16B8]

Like Stan, I've seen no difference with my own 23.976 footage.

This issue doesn't seem related to Markers directly, only incidentally.  The underlying issue is the footage showing a difference frame at the same location.

That's not normal with professional footage.  If it were cell phone or video game footage, it would be more understandable.

Unfortunately, I don't have any immediate ideas about what might be causing that for you.  It's not been widely reported by others.

I have seen others reporting similar issue at MARKERS or CUTS.

Here is one thread started by me, with other people replying with same issue.

Installed version 12.0.1. Markers Moved by 2 frames

Note: I later found that Markers didn't move actually. Only they are not showing the same frames as before.

Hi maximus1105,

The main question is WHY ARE THE MARKERS OFF and not showing the same video frames as before.

While I don't have an exact answer, I can guess that since there was major work done to the code for markers (as there is a major new feature added to markers: copy/paste sequence markers), it may have unexpected results in updated project files. Sorry for the inconvenience.

Thanks,
Kevin
