In this video I show a quick comparison between three common DNN upscaling techniques on real-life footage. This was a ton of work, I would appreciate a like or a comment :).

00:00 Clip 1: Video-Comparison - Low-Res vs. Waifu2x, SRMD and RealSR
00:39 Clip 1: Waifu2x vs. Original 1440p
00:59 Clip 1: SRMD vs. Original 1440p
01:18 Clip 1: RealSR vs. Original 1440p
01:39 Clip 1: Waifu2x vs. SRMD
02:00 Clip 1: SRMD vs. RealSR
02:17 Clip 2: Video-Comparison - Low-Res vs. Waifu2x, SRMD and RealSR
02:48 Clip 2: Waifu2x vs. Original 1440p
03:08 Clip 2: SRMD vs. Original 1440p
03:28 Clip 2: RealSR vs. Original 1440p
03:50 Clip 2: Waifu2x vs. SRMD
04:08 Clip 2: SRMD vs. RealSR

My setup:
I downscaled two clips to 360p with the following settings: h.264, 4:4:4, 2-pass ABR @ 4000kBit/s, High Profile, Level 6.2, Slower Preset, Film Tune. Resize to 360p using Lanczos scaling.

I used those 360p clips for 4x upscaling 360p to 1440p via Waifu2x-Extension-GUI.

The following upsampling settings were used (remaining options at default):
Waifu2x: Waifu2x-Caffe, upconv_7_photo model, "1-" noise reduction.
SRMD: SRMD-NCNN-Vulkan, "-1" noise reduction.
RealSR: RealSR-NCNN-Vulkan, models-DF2K.
