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 @kattgaldr, 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
. 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 
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.
