If you have the time VSGAN (https://forum.selur.net/Thread-Why-VSGAN-is-not-supported) with some models from https://upscale.wiki/wiki/Model_Database might be worth a try.

Hello Selur,
as suggested I tested VSGAN. The encoding speed is better, now a 30s movie is encoded in about 30m. This imply that a 1h movie is encoded in about 2.5 days.
But the faster speed is at cost of lower resizing quality.
For the comparison I performed a 4x resize of the following picture

Just for comparison the image encoded with Lanczos+sharpen is the following
![[Image: 0935-half-4-Lanczos.png]](https://i.postimg.cc/65D6NzpD/0935-half-4-Lanczos.png)
The image resized with VSGAN using the model 4xESRGAN.pth is the following
![[Image: 0935-half-4-ESRGAN.png]](https://i.postimg.cc/FHtCvJ5P/0935-half-4-ESRGAN.png)
The image resized with VSGAN using the model 4xPSNR.pth is the following
![[Image: 0935-half-4-PSNR.png]](https://i.postimg.cc/bvmKqNRs/0935-half-4-PSNR.png)
Finally the image resized with RealSR using the model DF2K_JPEG is the following
![[Image: 0935-half-4-Real-SR.png]](https://i.postimg.cc/50c8Y8gG/0935-half-4-Real-SR.png)
In my opinion the image obtained using RealSR is still the best among the tested resizer.

Speed wise you might also want to try RealSR_JPEG.pth (see: https://github.com/cszn/BSRGAN/tree/main/model_zoo).
Problem is to find the right model when using VSGAN.
For amusement I converted the suzie clip using the BSRGAN model a few days ago and it looked nice if you consider it's low start resolution.

(see: here for the video)
Sadly BSGRAN is mainly meant for faces, so it's really bad with everything else.
-> hoping there will be ports of tecogan, iSeeBetter and similar methods which are meant for video and not 'just' image upscaling.
