Since the latest update, using the starlight sharp model, it just hangs up mid process. Timer keeps running, but nothing happens. In the logs it is showing at the denoising part each time.

Can you share the logs with the support team so that we can review what is going on and have the devs investigate? help@topazlabs.com To gather logs, please select Help > Logging > Get Logs for Support and attach the zip file to your reply. Here is a video to help with the steps of how to collect …

same thing happens here whenever try to upscale to resolution above 1080p. But it works if upscale to 1080p.

I am trying to upscale videos that are in 720p. There is no option for 1080p thru starlight sharp. Minimum is still 720p and the next option is 2x which makes it 1440p. This worked completely fine numerous times, up until I updated the app and models yesterday.

I understand, the more logs and information we at the support level have to pass onto the devs helps with the situations. However, they still have to sort out the cause and how to fix it with the research team. We are also seeing various different situations in logs from different systems and use ca…

I’m retired from being a product manager of corporate data warehousing and master data management products. I totally get the problem of trying to reproduce the problem. I volunteer to do anything I can to help solve this issue, since it is forcing me to have two PCs available - one for Starlight …

Yes we are having basically the same issue. I was also wondering how come not more people reported this issue since the release of 1.4.0 - maybe not so many are using Starlight Sharp… So far the workaround for me as well is to downgrade to 1.3 till the issue is being resolved with a patch. It is no…
