Freeze bug demo

SUMMARY
Freeze does performs unintended actions on clip due to the resolution of clip different than project resolution. Such as relocating clip or readjust clip to fit video resolution of the project.

Examples, when using Mobile video recording [Video resolution: 384x864] (9:16) and make a tutorial about it in 1080p project (16:9)

STEPS TO REPRODUCE
1. Create a new project, set resolution to (in this case) 1920 x 1080.
2. Have a video (not image) (in this case 384x864)
3. Add video to timeline
4. Apply freeze effect to video

OBSERVED RESULT
After applying effect, video relocates to left side. (Also freezes the frame).

EXPECTED RESULT
Video should remain in center, freeze the frame.
