Anyone got much experience with the Hero 4 or GoPros in general? I have noticed in low light conditions or quickly changing lighting the playback tends to stutter quite badly on my hero 4. Night time, going through tunnels/trees etc. Most recently a vid filmed at sunset kinda killed off my hero 4 and all the footage seems stuttery.

I film in linear mode if this is important, with Protune and auto light on.

Maybe @WEB will know something in as I know he still uses the older cameras.

Turn off auto light, stick it in 30 fps too... when rendering remember that isn't true 30 fps (60 fps is not true 60 either) so set your render fps to 29.97

Sorry bruh, mine doesn't have the stock lens, and the shutter speed is locked off so it doesn't do automatically do anything, I just open the aperture way up to let more light in rather than using the camera's electronicals

If it's on the cusp of card speed, it might be bumping up the bitrate when it gets darker (to prevent banding in the low light areas etc) and that's causing the card buffer to overflow? Not sure

Thanks for the advice chaps, will try the 30fps idea and turn auto light off for sure.

@WEB I have the fastest card I could get my hands on but might try increasing the bitrate in low light as you suggest.

Thanks!

On a side note, I did try rendering in a higher resolution which you have suggested before to improve quality when uploaded to YouTube. But my computer really struggles past 2k, but from my testing, still made a big difference! :D

Awesome, technically if you were keeping the raw bitrate, the file should be no larger if it is at 4k vs 1080 as the resolution is just the size of the box, it is the bitrate that fills the box! :)
If however you lower the bitrate to be more YouTube friendly for 1080... then yes... that vid would be a lot smaller than a 4k at native bitrate. My upload today was over 20GB with a bitrate of 60,000kbps, took a couple of hours to render that one! :D

Hi Pooley, do you have examples of the video stutter? I use a Hero4, and had a frame rate issue dealing with background lighting. I was able to fix it in post with Adobe Premiere.
