I've got a bit of a mini-crisis: I re-coded a plugin which relies on Lr4 features, but needs to run in Lr3.
As coded, I'm needing to know the extension that will be used upon export, before export actually commences, for the video files.
(I'm presently using videoExportPreset:extension(), but that's Lr4-only)
Thanks in advance for any help,
I think I figured this one out - Lr3 just copies videos in original format (export extension is same as source).
That sounds right. Video support in LR 3 was very limited so no format
conversion capability was provided.
