Field Display Bug When Compositing VFX On MultiCam Clip

The Display Field... option in the settings of the programme negatively affects the output of interlaced footage when applying an effect on the video tracks.

Taking multiple cameras (all 1080i50), group them into muli-cam sequence.

Place on 1080i50 sequence and above place a 1080i50 fill then 1080i50 matte on v3.

Use a Track Matte effect on the fill clip (set to matte on V3 and using Luma for cutout) to key the graphic over the multicam sequence.

Now adjust the Display Field setting to First Field. This will play fine.

Now adjust the same setting to either Second Field or Both Fields. Now the background will display field judder.

Rendering doesn't fix it and I've seen this in 2024 and 2025 Premiere Pro.

If a non-multicam clip is used on V1 for the background then the composite will play correctly using any of the above settings.

Thanks @Todd-Dalton.

Have you tried enabling "High Quality Playback" in the Program Monitor wrench menu?

1080i50 means you are using interlaced footage.

Most likely, the footage is upper field. So, setting display first (top) field will be the best option for preview.

You can read the field setting of a clip in the Preview window in the project panel.

(lower field = bottom field)
