Question

Editing 4K clip on 1080 sequence in Source Monitor uses incorrect crop

Ran into this issue today and found a workaround but wondering if there's an easier way. I have a project with a 1080p timeline and 4K clips. I'm using the "Set to Frame Size" for my clips on the timeline so that I can pan/zoom the footage without loss of quality. If I double-click on a clip in the sequence to load it into the Source Monitor it displays just the crop, ignoring the "Set to Frame Size" setting, making source-monitor trimming/editing nearly impossible. However if I double-click the same click from my project window to load it into the Source Monitor it displays properly, fitting to size rather than showing a crop.

 

The workaround I'm using is to set the "Scale to Frame Size" setting for the clips in the project before adding them to my timline, then changing that to "Set to Frame Size" once they're on the timline. After that workaround if I double-click the clip on the timeline it loads properly into the source monitor, fitting to size rather than showing a crop.

 

Here's a quick screencast I did demonstrating this:

      The Source Monitor, by design, shows the source clip, and not the clip on the timeline. Once you place a clip on the timeline, it is an instance that only references the source clip. 

       

      Any edits made to a timeline clip do not affect the source clip in any way. For e.g. if you rotate the clip in the Timeline, it'll not show rotated in the Source Monitor, because that isn't applied to the source clip. Only Master Effects applied to the source clip will show up in the Source Monitor.

       

      Since your Source Monitor is 1080p, any 4K clip will show up cropped within that. The only way to get a larger clip to fit in a Source Monitor is to apply a Master Transform effect and scale it down. This is basically what the Scale to Frame Size option is doing - it's a pre-transform that modifies the source clip, so Premiere thinks it is of a different resolution.

       

      There are several techniques/workarounds you can use to assist with your editing - slip edits, markers, pancake editing with a 4K timeline, off the top of my head.

      Everything you wrote would make sense if it weren't for how the non-scaled clip still displays properly in the SM when loaded from the project window instead of from an instance in the timeline.

        You know what? You make a good point. The Source Monitor should be able to fit the clip, and I can't think of a good reason for it not to. Please submit a bug/feature request here, and link back to it and I'll upvote it: https://adobe-video.uservoice.com/

          What you are all seeing is by design.

           

          Why would you open the clip from the timeline into the SM to do what?

          Pan and zoom is done in the Program monitor.

          Not sure how it can be by design considering how the behavior is different depending on where the clip is loaded into the source monitor from and how that behavior changes based on the scaling setting even if that setting is overriden.

           

          Loading a clip from the timeline into the Source Monitor is done to edit the in/out points.

          I get the in and outpoint but you were asking for pan and zoom
