Rotated video via master clip Transform effect, incorrect Source Monitor aspect ratio.

I've rotated footage to the left (-90° aka 270°) by applying a Transform effect to the master clip. While the rotation is working fine and Source Monitor correctly reflects the master clip rotation Transform, Source Monitor still considers the aspect ratio to be that of the original clip (and not the rotated footage).

This sort of makes sense when considering I'm applying a Transform effect which doesn't change the footage's aspect ratio (i.e., the Transform doesn't flip 16:9 to be 9:16) but the reality is that folks will use this technique, to apply a Transform to the master clip, as a way of coercing footage into the right aspect ratio through rotation... like for footage shot with the camera at an 90° etc. Yet, I don't see any way to use interpret footage or Source Monitor settings to tell SM to show me the clip as I truly intend it to be...

I'm not saying SM should such a change from my Transform effect... but I'm wondering if there's a way to do this? If not, I'll file a feature request... it isn't critical... I have workarounds... it's just a pain not to be able to "interpret" source footage in basic ways relating to rotation... where afterwards the clip just appears that way everywhere.

I can get around this by hosting the clip in a seq that's loaded into SM but... well... it's just another extra thing... given we try to use nesting judiciously, as one example, wrapping something in this way just forces me to, well, wrap... not the hugely difficult thing to work around... just seems like a natural to allow interpreting footage rotation in -90°/90° terms at the very least... footage stays rectangular/square ... it just flips the aspect ratio... 16:9 becomes 9:16 etc.

    The source monitor is designed to read the original ... source ... including for orientation. If I export a clip as a  vertical 720x1280, then it automatically shows in the source monitor as a vertical. That's as designed.

    A number of people have written posts about the Source monitor not reflecting their grading of a clip ... um, no, it's a source monitor. Same thing, really.

    Rotation is so easily handled other ways, I'm still not sure of the need to rotate the source monitor. If I'm going to need to rotate a clip then cut edits out of it to drop on a sequence, I'd rather use a twin-timeline "pancake" editing UI, with the top one the rotated media, bottom the edited media ... cut & drop ... cut & drop ... works slick. And doesn't use the source monitor at all.

    that's a great approach... and I'm fine with resolving my issues by relying on sequences to fix footage... but that's... well... using sequences to interpret footage aspect ratio rotation adjustments. I was hoping to avoid wrapping low-level source clips in sequences to do those adjustments through the use of a master clip effect (Yet I get why it doesn't work that way... I'm rotating via an effect, not an interpret footage setting). ...and... You raise a great point, source monitor isn't named so because it's the "source plus effects" monitor... it's just the source monitor.

    I get it... just seems like a not unheard of use case and we so often hear of the bear which can arise from too much nesting... so there I go starting everything off wrapped in one of those (what are effectively) nests I so wish to use judiciously. It should just always work but it seems we also try to focus on economy in working with Pr ... avoiding nesting, layering, etc., if they can be avoided.

    Note, your solution doesn't require me to avoid rotating in the master effect... I don't gain or lose anything it seems by keeping my rotation there... actually perhaps I gain forcing a rotate as early as possible for something I know I'll never use otherwise. The thing which stands out to me that you're pointing out is to wrap in sequences to use the seq in SM or Timeline/Preview where they will look correct/spiffy (assuming my sequences have the right dimensions which they do). I'm skipping benefits of using a pancake setup as that's more about organizing and building a rough cut or beyond (after the rotation/SM issue is understood or solved)... correct me if wrong.

      Might want to trash preferences and plugin cache.

      My clips with the transform effect on the master clip shows correct opened from the project window in the SM.

      Even shows the effects applied in the Project window (thumbnails)

      Try clips other then phone footage.
