how to edit a 2 channel projection?

[Mitch Michigan]

Hello everyone,
I will soon have to edit a 2-channel projection for an exhibition. This means that I will be delivering 2 files, which will then run synchronously side by side on 2 projectors. My question to you: how can 2 timelines be separated in one sequence? I will create the sequence twice as wide as the footage, so that I can see 2 streams side by side. But how can each stream be edited independently while both are playing synchronously? Is that somehow understandable? I would be happy to receive answers. cheers.

Hallo in die Runde, 

ich werde bald für eine Austellung eine 2 Kanal Proketion schneiden müssen. Das heißt, es werden 2 Files von mir geliefert werden, die anschließend auf 2 Beamern synchron nebeneinadner laufen. Meine Frage an euch: wie lassen sich 2 Timelines in einer Sequence scheiden? Ich werde die Sequence doppelt so breit anlegen wie das Footage, so dass ich 2 streams nebeneinadner sehen kann. Aber wie lässt sich jeder stream eigenständig bearbeiten, während beide synchron abspielen? Ist das irgenwie verständlich? Würde mich über Antworten freuen. cheers.

Ich würde sie für den Schnitt temporär einfach beide auf 50% runterskalieren, eins auf die rechte Seite schieben, eins auf die linke Seite und so kannst du immer sehen was grad im anderen Bild los ist.

Danke für die Antwort. Das klingt eigentlich erstmal nach einer guten Lösung. Ich würde nur ungern jeden Clip, den ich in die Timeline ziehe, auf 50% skalieren müssen. Das würde ja im Verhälntnis zum eigentlichen Schnitt sehr viel Zeit beanspruchen. Alternativ könnte ich auf jede der 2 Spuren eine verschachtelte Sequenz ziehen. Dann hätte ich aber das Problem, dass ich für jeden Schnitt erst in die jeweilge Sequence gehen müsste, was mir wieder nicht sehr praktikabel erscheint.

It seems like nested sequences would be the easiest way. Going between the main sequence and the nested sequences shouldn’t be a problem, if you arrange the workspace properly.

Open all sequences. You will see the Program panel, and also the Timeline panel with three tabs, one each for the timelines of the main sequence and the nested sequences. Rearrange the workspace by dragging out those tabs and dropping them so that the timelines are now stacked on top of each other, so that you can see all three timelines in parallel.

As you play back the main sequence, you will see a frame where you want to adjust one or both timelines. All you have to do is, in the main sequence, double-click the nested sequence you want to edit. That switches to the timeline and Program monitor of that nested sequence, but also moves the current time indicator to the frame you were looking at in the main sequence. You will be right where you need to be in time to make that edit. When you finish that edit, you can click the main sequence timeline and the Program panel shows you the side by side view again.

So there isn’t much going in and out of sequences, just leave all sequence timelines visible in parallel and click the one you need to work on at the moment.

Also, I see no need to scale anything. For example, if it’s two 1920 x 1080 projectors, I would just make the main sequence 3840 x 1080 px, or 2x width. After adding both 1920 x 1080 nested sequences, the only edit for the nested sequences in the main sequence is to use the Motion/Position property (in Effect Controls) to move one nested sequence 960px to the left, and the other one 960px to the right, so that they’re side by side. All other edits should then be made in the nested sequences, because the only purpose for the main sequence is to simulate the side-by-side projection. Because when it’s all finished, of course what you will export is each nested sequence separately for its own projection screen.
