Slo-Mo video sometimes not working

I've had issues when viewing the videos in Google Photos as well. Not sure if it's related to the video or other HDR photos still processing, or just Google Photos doing whatever it does to index them. I have sync set to charging only and wifi only, but when I was at my grandma's house taking videos of her dog jumping and doing tricks, when I played them back they would play OK the first time, but if I started moving the sliders and jumping to different spots in the video, it would freeze up or get really choppy.

Hoping it will be fixed with an app update soon.

I am having the exact same issue you described. It's not a playback issue. It's choppy even played back on a computer.

It is supposed to capture at 240 fps and stretch that out into a 30 fps video file. Look at the properties of a slow-mo video file, it should say something like 29 fps. When mine isn't working correctly, and the playback isn't smooth, that video file's properties says 7 fps. So, it seems like it's capturing 4 times slower than it's supposed to, at 60 fps or something.

Restarting my phone fixes it, for a few days. I've only had the phone a couple weeks and have had this happen twice now. No clue why this happens. Surely it's more widespread than just us.

As for the grainy noise, you have to have a lot of light, more than you'd need for a normal video. Mine are pretty grainy unless there's a ton of light.

Yeah, mine becomes choppy too sometimes. A reboot fixes it for a while. I've seen this issue posted a few different places so I think it's a software/firmware problem that Google will need to resolve.

Just wanted to add that I have the exact same problem, meaning that it still hasn't been fixed.

I know this is an old post, but I just got a 6p and I too have this issue. I'm even on DP4 so it's not fixed yet in this release either... Reboot is the only temporary fix I've found.
