Topaz Labs on TokenRex — common questions
Can Starlight Fast 2 make a video from a prompt?
No. It only restores and upscales a video you provide. There is no prompt, quality or audio control.
How is it charged?
By processed frames. Frames = end index − start index + 1. Units = frames ÷ 52.0833 at 1080p or ÷ 23.8357 at 4K, rounded up. Each unit has a fixed price.
Which upscaling factor can I use?
Only 1. The output size comes from the 1080p or 4K tier you choose.
Does my video need a public link?
Yes, a public HTTPS link. In the TokenRex Playground you can upload a file and TokenRex creates a private link that expires after 48 hours.
How long does a job take?
From minutes to hours, depending on length and tier. Results stay downloadable until the job's expiry time.
