Welcome to my 💫🔼 Friendly FLASHVSR Super-Resolution

✨ Less mess, more magic.

🆕 FLASHVSR v1.1 support added - enhanced stability + fidelity

⚡FLASHVSR is a new single-step 4K video upscaler that restores detail even without increasing resolution. It also works with long videos more than 1 minute length. Topaz Starlight now has a strong competitor! According to the developers, the upscaler can generate in real time on an Nvidia A100. This is all thanks to its unique architecture and a modified Wan 1.3b model.

At the same time, it runs quite fast even on low-end graphics cards and offers flexible settings.

Video upscaling to 4K works even with 10 GB of video memory! (tested on the 7-second video).

📌 8GB of VRAM and 32GB RAM are sufficient for operation, but the more the better.

• If you have 16GB+ VRAM use 4x upscale for better quality

• For less than 12GB VRAM 2x upscale recommended for first run, and 2x upscale again after. Finally it will be 4K video. 2x upscale is much lighter even with high resolution input videos

• For Low VRAM use mode "tiny" and "tiny long" (for long videos). You can use "full" mode with better quality but it's slower. You can switch on "tiled vae" for decrease VRAM peaks

💫 Benefits of Friendly FLASHVSR Super-Resolution workflow:

• User-friendly interface with detailed tooltips and links to everything you need to use the upscaler

• Ability to downscale the source video to reduce system load

• Ability to upscale long videos (longer than 1 min)

• Post-processing: interpolation, adding grain, brightness, contrast control, stylization, and much more

• FLASHVSR requires Triton and SageAttention installed. It's also important to install requirements.txt from the node folder
