SUMMARY
STEPS TO REPRODUCE
1. Make a 2160p project
2. Insert a 2160p H264 clip
3. Make a proxy of the clip
4. Insert the clip into the timeline
5. Add transform to the clip
6. Switch preview resolution to 720p
OBSERVED RESULT
Preview resolution is unreasonably low. Once Transform is disabled the
resolution becomes normal.
EXPECTED RESULT
Adequate preview resolution when using the Transform effect.
