No worries. It is why I'm using Manjaro (an arch derivated) because I have arrived at the same conclusion. For sample, watching the same video on SMplayer on the both system and you notice a different result, perfect on Manjaro.
You should use/try FFmpeg and not his fork (like now). It will be removed OS and all software using it but after you could reinstall them easily.
