A simple workflow for using the spatial upscale stage in LTX 2.3 to upscale any video. The LTX2.3 model upscales videos but adds its minor details and variations to the video.

V2.0

• Played around with sigmas for the upscale. Consistency to original video has been improved significantly.

• No need to bypass individual nodes anymore. Use the Groups bypasser node to enable or disable the generate audio module

• Works better with prompts describing the video or the audio you want

• LoRA dependency is reduced, but will do better with them for specific scenarios

V1.0

• LTX2.3 model adds realism to the video while upscaling with added details

• The workflow can upscale to 1.5x or 2x, depending on the spatial model used (Download from LTX2.3 Huggingface repo)

• One of these nodes needs to be bypassed depending on whether the original video has audio - LTXV Audio VAE Encode or LTXV Empty Latent Audio

• A LoRA might be needed based on the content of the video

• A brief description of video for positive prompt or can be left empty
