// Extract audio to our video folder

// Scale images: -s valid options are 1 2 4 8 16 or 32

// Put video back together lower -crf means better quality but larger file sizes
// MAKE SURE YOU CHANGE THE FRAME RATES FROM 24 TO THE ACTUAL VIDEO FRAME RATE!

==== LINUX ====

// Make the 3 additional subdirectories we will be using
mkdir video
mkdir frames
mkdir scaled

// Install ffmpeg directly - no need to download it like with Windows!
sudo apt install ffmpeg

// Get info about video: i.e. frame rate and dimensions

// Extract images to our frames folder

// Extract audio to our video folder

// Scale images: -s valid options are 1 2 4 8 16 or 32
./waifu2x-ncnn-vulkan -i frames/ -o scaled/ -n 2 -s 2

million thanks for the cmd tip you gave at around 10:00, never knew that after being soooo many years in windows, shame for me haha.

Hi, thank you very much for the wonderfully explained video, I manage to convert some really old 352x240 videos to 720p! I got a question you might be able to help me with though. The upscaled video plays just fine with mpv (in linux), but the screen is black if I play it with VLC. Any ideas?

Edit: I just though to copy and paste the video to a Windows PC and try to play it there, same issues with all the players. So it looks like the ffmpeg conversion from frames to video did not work as expected! I will investigate further.

Edit 2: I just had to add `-pix_fmt yuv420p` in the final ffmpeg command before the `output/`. Hope this helps somebody one day!

So for some reason at 13:00 i have stream #0:2 whereas you have only stream #0:0 and 0:1. Is it possible to delete the extra stream in the commands?

Awesome instructions. It worked all the way, but does it only work on VLC player? What codec will allow it to play on QuickTime Player?

Hi thanks for you tutorial and the tool of course. I followed every step but when making the resize step i got the following error: vkCreateInstance failed -9

Hi! Is there a difference between this one and Waifu2x GUI from your vid in November 2022?

How did you get your background like that? It's so cool. Thanks for the tutorial.

Do you have any suggestions for interlaced video? I've got some laserdisc captures of anime.

Hey man! Nice video! What is the main difference between this and the other tutorial you made 6 months back?

[billbundle]

How can I do this in VirtualBox? Do I have to download and install some other video driver?

[PigTownSports]

will this upgrade a 1080 video to 4k ? and is there a noticeable difference in quality?

[Shise-]

Any different with this vs the GUI one?

I have this error "../src/intel/isl/isl.c:2216: FINISHME: CCS for 3D textures is disabled, but a workaround is available."

I use waifu2x, and it'll upscale without all this extra steps

I always trust a video with no examples.
