Bug 356314

This bug is still present in most recent git master. As I'm grading either individual clips in the timeline or a complete track, I cannot do this with a before/after split view. In some situations, the project monitor only shows a quartered after view, sometimes it shows a full monitor after view. But it never shows a split screen.

Project monitor not showing split screen despite active split screen mode

Ok, there is probably some confusion here. The project monitor's "split view" option was introduced long before the clip monitor's "Split" feature and is a completely different feature.

The project monitor's "split view" function is in fact a multi track view. it splits the monitor in 4 parts, displaying the 4 top video tracks individually in a quarter of the monitor. This was designed as some kind of multi-cam utility. However, the introduction of the composite transition in tracks kind of breaks the view, and you need to disable track's composite option to make it work properly - That could be done automatically at some point.

So I guess you are asking for a "split view" in project monitor that would behave like in the clip monitor ?

Jean-Baptiste, as you describe at the end, I'm asking for a "split view" in the project monitor in the same way as for the clip monitor. This would help me and hopefully also other users in their workflow. The rationale is that I have a set of raw footage clips shot under the same conditions, so grading each clip individually is a pain, especially when later doing some last-minute corrections.

Now that I've learned what the original "split screen" means I would ask to rename this to something like "multitrack view"? It would be great if such a multitrack or transition view could be made to show the A, B frames going into the transition, as well as the outcome ... so kind of triple view?

A note on the existing multitrack view: I'm constantly working with between 5 to 8 tracks in my projects. In this setup I use tracks for dedicated purposes. Most "live" clips are on bottom tracks, while upper tracks contain different overlays, such a paper background getting multiplied into a clip, or a title bar, et cetera. In consequence, a four corner display typically doesn't work for me.

It would be great if the multitrack view could be developed further.

1. For instance, what about controlling the tracks to monitor in multitrack view using a new "view" toggle in the track headers? Such as an eye in a window as an indication? This way, the editor has close control over the tracks getting monitored.

2. What about modifying multi track view to have three states? a. multi-track view off; b. 2x2 multi-track view; c. 3x3 multi-track view?

Jean-Baptiste, on another note: shall I draw up a new icon for multi-view mode? My idea is to take the existing single window metaphor, but with dotted lines that divide this window into four quadrants. What do you think?

Can be closed as fixed.
