Replace With Clip From Bin - Not respecting In/Out Points?

I'm not totally sure what you mean by insufficient matrerial?

There is no shortage of ways of lining up footage manually, just wondering if the way this feature is functioning is how it is supposed to.

In other words, the scenario I'm in right now, is I'm just replacing Stock footage that has a watermark, with the newly purchased stock clips that are the exact same clip but clean.

So, in the scenario of a more complex edit, using "Replace With Clip" would be amazing if it repected the exact In/Out points that are already on the timeline.

Instead, I have to do it manually. (fwiw I'm just double clicking the clip on timeline, opening it in Source monitor, noting the In TC like 0:24 and matching it on new footage and dragging).

Wondering if I should do a feature request then. It's just weird because I swear this worked in the past. Maybe I'm wrong tho.

If you have insufficient material, just drag the new clip to the timeline and watch the Program monitor for the correct frame.

I see, so this is intentional?

That is correct.

Easiest way is to use from Source Monitor, Match Frame.
