Hi,
I was asked to record a concert the other night and i used my osmo pocket to record some video.

All was going great until i decided to film in 4K (30fps). Between songs i switched from 1080p (30fps) to 4k (30 fps).

All the songs i recorded in 1080P came out nicely, but all songs i later recorded in 4K came out too blurry to use. ( which i didn't realize until transferring files off the PC and watching them)

It was definately a 'low light' type situation, although the stage was well lit.

I have since filmed in 4K (30fps) to try and replicate the blur, but it's not blurry.

Any ideas on what might have caused this?

It almost seems as if switching between 1080p and 4K video without restarting the Osmo Pocket led to this.

I really hope there's some rational explanation for this and hopefully a fix.

Luckily i had other cameras going, but this has shaken my faith in the Osmo Pocket, which i really love.
Thanks for any feedback,
Colin

Were you on AFS?  If so did you check you had refocused?
