Great news, UniFab AI users! Our Video Upscaler now supports upscaling up to 16K resolution , delivering unprecedented clarity, sharpness, and detail for you...

Nice but there is a bug currently as if you upscale a video for example to 4K, the upscaler does not keep the picture ratio and the outcome is a distorted image which is not acceptable. When you upscale, you must keep the picture ratio. So please fix that bug.

Working with support on this one.

Another nice bug encounter today, I am trying to upscale a 1080p H265 DoVi profile 8 video to 4k, there are two bugs there.

If using autopilot, the conversion works till reaching 100% and then it is stuck there forever
IF using the dedicated app, this works, but the resulting video is a 4K H265 file but no more DoVi profile 8, conversion just dropped it completely, very nice bug.
The file to test is there: https://drive.google.com/drive/folders/1ZVJpyLRYdIgTmESNnB8kPFolRrmMPSIg?usp=sharing

Which models are applied in Autopilot? Which mode got stuck at 100%?
Currently, only retention of source HDR10 is supported. Files with source HDR10+ (HDR10 Plus) or source Dolby Vision (DOVI) are not supported.

Alex_Videoman

No HDR model I just tried to upscale my video which is a DoVi 1080p one.
It seems that you say it is not supported by upscaler, but yet it is not advertised anywhere in the notes or lack of.
When are you going to support these then?
What solution do you offer me to do this?

vivi

Alex_Videoman Video Upscaler does not currently support retaining DoVi profile 8. We are unsure when this feature will be added.

Alex_Videoman

vivi ok this would be good to have at one point, please add this into the FAQ or release notes…

Alex_Videoman

Also does it retain Dovi Profile 5 or HDR10+ so that we have all the data?

vivi

Alex_Videoman It doesn’t retain Dovi Profile 5 or HDR10+ at present.

ok good to know
