Program/Source preview is zooming on playback. NOT sequence settings.
I'm hoping someone can help here, as I've found nothing else online.
Usually my paused resolution is full, playback is 1/4 - however when scanning through the footage, or playing the clip - it zooms into the top left corner. If i pause the footage, it then zooms back out again. This happens in program preview, and in the source preview.
If I select playback resolution as full, it doesn't zoom. But if I put the playback resolution on 1/4 or 1/2 - it zooms in (even if I lower the paused resolution to match the playback resolution).
If I drag the marker along the timeline to see the footage, it also zooms in again - until I let go of the marker and it zooms back out.
Sequence settings match the footage. It doesn't happen once the footage has been rendered. I've tried 'scale to frame'. No luck with that either. Magnification is to fit. I've tried with a variety of codecs.
Can anyone help me with this?
(I've also tried re-installing Premiere, and checked drivers for updates)
