I am currently working on a project with 9 Multicam cameras. A number of errors make Premiere unusable for this.
I have a "Multicam" sequence in which the 9 camera tracks are located. This sequence is then integrated as a clip in the "Main" sequence, and Multicam is activated for the clip.
The first problem: When I select a clip from one of the nine camera tracks in the "Multicam" sequence, the corresponding effect settings are shown for the selected clip. As soon as I change even one value in the effect settings or click with the mouse, the effect settings disappear, but the clip is still selected. I first have to deselect the clip and then select it again to make the effect settings visible again.
The second problem: I want to correct the colors of the individual camera tracks in the "Multicam" sequence. As long as I don't use keyframes, this works fine. But as soon as I create a single keyframe, no value is applied and only the value that was used before the keyframe was created is used.
I have tested the whole thing with versions 23.6.2, 24.1 and 25.4, with all versions I have these problems.
I am testing on a Macbook Pro M1 Max 14" with 64GB RAM (Apple Silicon) mit macOS Monterey 12.7.2.
With these problems, Premiere is no longer usable for me and I have to switch to other software, although I would prefer to stay with Adobe.
