I use the Topaz astra video upscaling but it generates an image and it doesn't even generate in 4k.

Hi Alessandro.rugel.01,
 

Thank you so much for flagging this.
 

Using the video upscaling feature should not generate an image, so we’d love it if you could share the original video you used along with the image that was produced. (Feel free to send them privately if you’d prefer not to post them publicly.)
 

These details will help us better understand the nature of this behavior and get it looked into.
 

We appreciate your help, please keep us posted.
