Offline rendering using Unity Recorder

How is possible that UnityRecorder isn’t able to record offline rendering yet?
Are we forced to buy very expensive plugins on the assetstore to do this? I need to record 8K videos from the editor on an HD PC, and if I use Unity recorder obviously there are frame drops.
Am I missing something?

Thank you!

The offline recording is working fine with Unity Recorder 2.0.3. What version are you running?

You specify the framerate, resolution and click record. No frame drop at all.

Offline rendering doesn’t seem to work for image sequences - lots of dropped frames if it can’t keep up, but does for movies.
