Pr [Beta] Rotoscoping not included in batch exports via Adobe Media Encoder

[Bingoconcept]

I have a batch of videos that required rotoscoping with the new Rotoscoping tool in Premiere Pro Beta. When I send the batch to Adobe Media Encoder for export, the files are produced without error messages, but the rotoscoping is missing in the final renders.
If I export clips one-by-one from Premiere Pro’s own Export panel, the rotoscoping is included correctly. However, exporting individually is not a viable workflow for me because I handle large batches of videos. This suggests the problem is specific to Adobe Media Encoder in batch exports.

Steps to reproduce the issue:

1. Import a batch of videos into Premiere Pro Beta.

2. Apply the new Rotoscoping tool to each clip.

3. Select the clips and choose Send to Adobe Media Encoder.

4. Export the batch from Media Encoder → the final files are missing the rotoscoping.

5. Control test: export the same clips individually from Premiere Pro’s Export panel → the rotoscoping appears correctly.

What should have happened:
All exported files should include the applied rotoscoping, including when queued and exported via Adobe Media Encoder.

What actually happened:
Rotoscoping is omitted when exporting via Media Encoder. It does appear when exporting one by one from Premiere Pro’s Export panel, but that is not practical for large batches.

Third-party plugins or panels installed:
None.

Hi @Bingoconcept - If you’re exporting with AME, go to the Beta menu in the menu bar and make sure masking is enabled.
