Yes I have tried it.
- It takes a very long time to process a video. I recorded a 1 minute video and it took around 4 hours to process.
- I find it just blows out highlights and oversaturates colours in the day time and at night, it gets about as bright as the Galaxy S23U video.
- It's limited to 10 minute videos.
- You have to annoyingly go to the video section in the camera app, then press the settings button then turn it on every time you want to take a video boosted video. It's not one of the swipe options on the video settings.
It's better than the default video quality, but I don't think it's amazing. It just looks better because Pixels doesn't have great video to begin with.
