Context

Users working with high-quality video formats like QuickTime ProRes 422 may want to maintain the original format throughout their workflow to avoid unnecessary quality degradation during processing.

Answer

Currently, the Premiere plugin and API always re-encode videos to H.264 as part of the standard processing pipeline. This means that original formats like ProRes 422 cannot be preserved on creator plans.

However, ProRes workflows are supported for enterprise customers. If maintaining ProRes or other high-end codecs is critical for your pipeline, you can contact the team to discuss enterprise options that support these workflows.
