Color clip adds mystery frame to a cut video clip???

I love the software but I am baffled by something. Here is the scenario.

Two videos for example. Both 59.94 FPS.

Both cut at 02:49,21.

When I add a 00:03,00 black color clip to the beginning…video “A” stays the same with 3 seconds added, so it becomes 02:52,21, normal…BUT video “B” becomes 02:52,22.

So video “B” gets an added frame. But I looked, even zoomed in, and the beginning and ending few frames are the same. So where is the mystery frame that gets added to the total time. So strange. It only happens on this one video. Oh and it does not add that frame/time to the audio.

The only difference between these two is one is 1080P and one is 2160P. But there FPS is the same.

I am hoping someone smarter will just tell me it is because of the resolution or something.

The end result is fine but my obsessive nature is just curious, more so.

Hi @anon23486614, and welcome to the forum and community.

Can you share the video clips or perhaps just a short section of it for testing purposes? I don’t have any handy rn.

Thank you for your reply. They are just some Elden Ring trailers I got online for the memories :blush: . You could tell me how to provide them here, although they are quite large. Or if you are into occasionally borrowing videos from our overlords at Google I could give you the link. Or I could provide step by step screenshots.

And what does “RN” stand for?

Right Now :wink:

Sorry, I thought everyone knew about LOL and AFK and so on …

Oh I see. No. I am not very familiar with internet lingo beyond “LOL”. After America Online I took a break for 20 years and just in the last year or so, built a PC, so on.

So I just checked again.

Added video. Start cut 00:02,00. Dragged to position 00:00,00. End cut 02:49,21. Play time 02:49,21. Add 00:03,00 black color clip to beginning position 00:00,00. Video position now 00:03,00. Play time 02:49,22. So weird! Only this video. I even opened other videos of a different codec and resolution in the same project settings (HD 1080p 59.94 FPS) and they did not do that.

Also. It seems to happen when moving the start position anywhere after 00:01,40. Before that nothing changes.

I think this has to do with FPS in the video, project settings.

For example, at these project settings, 59.94 FPS, the timeline goes from 00:01,58 to 00:02,00. There is no 00:01,59.

Similarly how, when working with a video that is 24.97 FPS, the timeline goes from 00:01,24 to 00:02,00.

It seems obvious now. Why it only changes the end time on the 1080P video and not the 4K video, same FPS, I do not know.

Your specific examples are incorrect, but yes, you’ve got the basic idea of how drop code timecounts work to give you 59.94 etc.

And that does not (alone) explain what you are seeing with that one particular clip, but frame size should have nothing to do with it. My first guess would be something about how the timecodes in that specific clip are recorded.

Thank you for your reply. Although I do not fully understand. You read my original post, yeah?

Ok. I think I figured it out. It seems obvious now but I was not sure :man_facepalming: . When I begin a new, empty project at 59.94 FPS (Like I did with the 1080P 59.94 FPS video I was working with) and go to 00:59,59 it skips to 01:00,01. It does this at the final frame of each minute, roughly. It does not do this when I begin a new, empty project at 60 FPS. Well this is what has been throwing off my editing, cuts, and trims and such by a frame. I will just use the frame counter from now on instead of hh:mm:ss:ff as it does not happen with that. A simple oversight, lapse in logic, whatever. I suspected it had to do with this but could not pin point it until now.

It’s not “roughly”. It’s how drop code time counting gives you ‘precisely’ 59.94fps.

And as I (also) said before, it


No, I just woke up and posted the first thing in my head to this thread completely at random. Do you think they are somehow related?

Although I do not fully understand.

Apparently not. But you have not said anything since which gives us information to say anything more about this than I already have.
