Video quality is fixed to 720p @ 30fps with h264 compression, this is a hardware limit.

Both are using the same source, but video on top of that uses very strong compression, so good luck

Ok nvm, it just sucks no one made a workaround

Only way afaik would be to make an exlaunch plugin that can catch framebuffer, copy it from gpu only memory to memory accessible by cpu and save it as file.

Hi,

Thanks for your work so far, it's really helpful! How difficult would it be to modify the Switch's standard JPG saving functionality to save screenshots at Q100 (ideally without chroma subsampling), rather than saving a PNG file separately? When playing on my Wii U I found that this was the optimal way to get no visible artifacts while halving the save time relative to PNG. On Switch the save time has not been a problem so far, but PNG files have the new drawback of not being visible in the system album app (to browse and delete photos), or to most homebrew used to browse the entire gallery wirelessly from a PC.

I'd have to take a look at ways to save as jpegs. Not sure off the top of my head how configurable jpeg-turbo is.

I did at one point start adding code to see how lib-webp would work out, but dropped it for some reason. I was gonna add flags that would change what files got compiled and just add source files or modules for different formats that use the same function signatures to make it interchangeable.

I'll see sometime. I'm really tired right now. My cat was diagnosed with diabetes yesterday and I've been watching him like a hawk and barely sleeping for the past week to make sure he's OK. He's 16 years old and he's my buddy. He is priority number one right now.

issue with JPG is that it has fixed buffer size. It may start from 100% and reduce it until it fits.

Best wishes to your cat
