Hey, thank you so much really glad it's been useful! 🙏
Found the bug, the frames are saved as a numbered sequence, and if a gap slipped in (which could happen around heavy layer work where a snapshot occasionally failed to save), the encoder stopped at the first missing frame but still reported success so you'd get a fraction of the frames with a "done" popup.
Just pushed an update that fixes it: if you re-download and install the plugin the export now stitches the full sequence together across any gaps. No need to re-record just update and re-export your existing session and all the frames will be there.
Thanks for the great report! 🙌
If you still have problems let me know
