@Brianhill4254254 Thanks for the feedback — both issues have been logged.
On the FabCloud version failing: we’ve flagged this for the engineering team to investigate. In the meantime, splitting the video into shorter segments before uploading may help work around the failure.
On the local version quality and speed: Video Colorizer AI’s local processing requires an NVIDIA RTX 30-series GPU or above (8 GB VRAM). If your RTX card is below the 30-series, that could explain the incomplete face colorization and the 3000+ hour estimate in Slow Speed mode.
We’d also recommend trying the Colorizer - FabCloud version — it processes faster and has had some fixes applied recently.
