There’s already a Fairphone 3 pictures gallery - so why not a video gallery, as well?
I just recorded a music video on my FP3. I think the video quality is acceptable, but not great.
For this recording, I used the standard camera app with the highest settings. I added some vignette effect afterwards and changed the colour settings a bit more red-ish and warmer tone.
As @Mixigodo has already stated, the audio recording of the FP3 is terrible for music. See also bis post with a solution to this: Very low quality audio recordings
In this video, i used an additional audio track from some decent recording equipment. You can listen to the original audio quality in comparison in some outtakes at the end of the Video.
