Drag and replace clips in timeline doesn't maintain speed adjustments

This bug has had me pulling my hair out. I have done EXTENSIVE trial and error runs on this to absolutely make sure that there is frame my frame, fps to fps, original clip in-to-out point, timeline spec matchup, etc etc etc indentical details on these and is doing a very strange thing.

In my situation, I have two different camera angles of a live band that we filmed during a sound check so that we could have additional camera angles of them performing after we filmed them again from the audience during the live show. Things like close up fretboard, snare drum hits, etc.

So I went through and edited Camera 1's Soundcheck take, cutting and stretching it into dozens of smaller clips to perfectly line up tiimewise to the actual live performance of the song (this band does not play to a click). Then I re-rendered Camera 2's sound check to be completely synced up with Camera 1's Soundcheck video, and trimmed and added/removed length of Camera 2 so it would be, frame by frame, exactly the same length as Camera 1.

When I do Alt-Shift-Drag to incorprate Camera 2's footage into an identical copy of the clipset i've edited for Camera 1, the in and out points shift by a subtle (and seemingly random) amount of frames. It's not like it's all shifted by 9 frames across all the clips or something, so I'm guessing it's the time stretching that is messing stuff up like you've noted.

If nothing else, it's helpful to hear that 1. I'm not the only one experiencing this, and 2. someone here seems to be acknowledging that it is a legitimate bug, because it's absolutely maddening and the fact that the technology IS HERE and just NOT WORKING CORRECTLY makes all the extra hours of workaround edits so defeating.

I'm here to confirm that the Premere Pro (Beta) as of November 2024 DOES in fact work, but it didn't work when I highlighted all my clips and Alt+Shift=Dragged the replacement clip to be one and done. When I did it that way, it only worked appropriately for the first clip. BUT, if I do that one by one with the Alt-Shift-Drag through each clip one at a time, it works! 

Still annoying, but about 1/100th the amount of time than going through manually for dozens of tiny clips to re-timestretch exact sections.

Updating the status of this bug report.

I'm still getting it to work in both 24.6.1 and beta 25.1.0 b10. I'm using alt-drag, alt-shift-drag doesn't respect an in-point I select in either the project icon view or in the source monitor.

Did you try it with a new project, drop in 4 clips, setup the 3 with the middle clip having the speed/duration change (to 200%), then set a inpoint as above, and alt-drag (option-drag) it in?

Running 24.6.1 and the problem still persists. For those who were interested the source footage varies, and doesn't have any bearing on our results, so far as we can tell. It will fail via Pro Res footage replace Mp4 clips, amongst others (Sony, Canon, RED).

I still have to temporarily change the speed of the clip back to 100% before replacing the clip in the timeline (NOTE: that is by using "Clip Speed / Duration" not "Time Remapping"), Option-Shift Drag onto the existing clip (that is the correct key combo for Premiere, it's unfortunately different than AE), then I can change the speed back to the what it was in the edit. The expected result is that it should inherit any attributes applied to the clip in the timeline, it partially does this by maintaining the speed at 200% (in this instance), but offsets the IN/OUT points, by the number of frames it would have been at 100%. Total mess.

I appreicate the suggestions, there isn't an issue with our workflow, there's is just simply a bug in the application. This method works perfectly fine in After Effects every time. And that is with footage that has been re-interpreted to a different frame rate, and then stretched in the composition timeline.

Which version of Premiere Pro are you in?  What is the file format of the source?

I just tried option drag and drop to replace a Clip in the Timeline and the Clip Attributes, including Time Remapping, remain as expected.

This is Premiere Pro 24.1.0 under macOS Ventura 13.6.3.  The source clips are 5 second QuickTime movies running at 29.97 frames per second that use Apple ProRes 422 compression.  The speed change is from 100% to 50% then back to 100% using two keyframes.

If you're not able to figure out why you are not getting the same results, I'd switch to using Paste Attributes to match the Time Remapping on the replacement clip as you go through your Timeline.

It is a super time consuming process, however for multiple reasons I wouldn't want to relink the source. First it would mean having duplicates of my files with the same file names so I can relink everything in one shot, but from a different folder. That feels like a recipe for disaster down the road incase for some reason the source gets accidently deleted. 

The reason for doing a replacement in the timeline / in context, is so when the client innevitably comes back with changes, it's easy to go back and reference the original clip, if needed. I save a copy of the sequence just before doing this incase anything goes wrong and and I can revert back to the original or pull a clip over and perform the replacement again.

Option drag doesn't maintain the in / out point. You have to hold down SHIFT in order for it to inherit the in / out points. Option replace works in AE. It's a typical Adobe issue where two teams don't talk to eachother to make the same functionality more universal. Also it's important to note that my bigger issue is that if you Speed Change the clip, this method breaks. That's my real problem. 

I'll take a look at the "replace clip from source" option and see if that would work. 

Thanks for the notes.

That sounds like a really bad workflow! 🙂

It seems to be working for me. (v24.1 Win11 22H2)

I took a clip and applied time-remapping.

I took that clip from Explorer and dropped it into ShutterEncoder and made a ProRes proxy file

Imported that file and Alt-Dropped that file onto the original, and it seems to have worked.

(BTW: The screen shot below is w/out the Alt key, as my snagit, doesn't work with it pressed - but I did hold it as I dropped it)

For what you're doing, first try Ann's option.

Second ... if you selected the clips in the bin, Offline, then relinked to the graded clips, I think that would also work. On batches of clips at a time. As it wouldn't be changing the sequence data. I ... think that would work.

Easy enough to test. And for this process, that would have been my first thing to test. One by one replacement sounds time-consuming.

Just OPT not shift+opt.

Have you tried to Replace with clip form source monitor with frame match.
