Starlight HQ

Introducing Starlight HQ, for local desktop rendering! Starlight HQ is the fourth variant to the desktop Starlight Model Family. This diffusion model has a great balance of detail and sharpness while keeping the intent of the original video source. Provides higher quality outputs for a wide range of videos, though not necessarily intended for archival content it can still provide good results. Though addressing similar intentions as Starlight Fast2, outputs have generally been higher quality and consistent with this model’s longer processing time.

The following available outputs are multiplied relative to the original resolution or minimum/maximum resolution threshold for the model:

• Minimum
• 2x upscale
• 3x upscale
• 4x upscale

If your content is already at the max output, such as 4k, then no matter the scale factor, the max output will be rendered:

• Minimum (3840x2160)
• 2x upscale (3840x2160)
• 3x upscale (3840x2160)
• 4x upscale (3840x2160)

Things to know:

• Nvidia Only
• Supports 480p to 4k inputs.
• Recommended to use video inputs at or under 4K.
• Outputs between HD - 4K renders.
• This model works for Medium to High Quality content whether this is generative or live action videos.
• Processing speed is very similar to Starlight Mini.
• Requires a minimum of 10GB VRAM though 12GB VRAM and up is recommended.
• Model access via the cloud for all subscription models.
• Cloud Export supported

This model is less ideal for content with:

• Haloing issues common with vintage digital videos.
• Hair quality can vary in detail when content is on the lower medium spectrum.
• Not intended for very low/poor condition quality media.
• Interlaced content needs to be de-interlaced first.
• Small repeated patterns can flicker.

Starlight AI Model

Starlight HQ is a model variant of Starlight.

• You will need to first select the Starlight AI Model.

• Just a little below, you will see a section called Model Variant. This is where you will click on the caret to reveal the drop down menu. The fourth option is Starlight HQ.

• If this is your first time using the Starlight Model, you will be prompted to “Run system check” before you can download the model.

• Once you click on the button, the system check will conclude if your system can indeed run the model and you will be given access to download.
• When the download is complete, you can close out of this window.
• Now that you have the model downloaded, you can now use it on your videos.

Starlight HQ Notes and Reminders

• You will need a Pro account to render locally.
• Starlight HQ is currently only available for local rendering to Windows users with NVIDIA GPUs.
• This model is quite demanding in terms of VRAM, requiring a bare minimum of 10GB or more in order to run the model effectively.
• It is also recommended to have 12GB of RAM.
• This is still a diffusion model, so long render times are expected when rendering locally.
• Recommended to use square-pixel video footage at or under 4K UHD to avoid any aspect ratio shifts
• Ensure that you are using the latest driver for your graphics card.
• Currently capped at 4K resolution locally and in the cloud.
• Starlight HQ is a standalone enhancement and can’t be combined with other filters.
• It is not recommended to run Preview or Frame Preview with this model. It will not work. It is recommended to export a few seconds for Preview purposes.
• Please note that if you have text that is too small, blurry or inconsistent, the result may not be processed correctly. The AI model may interpret unclear text as a texture or pattern.

• If you have interlaced videos, it is recommended that you de-interlace first before enhancing with with this model.

Have a great time with Starlight HQ!
