I love using my Osmo X3, butni would like to reiterate what others have said. There is definitely a problem with the codec or something. My video looks grest until it is uploaded to Vimeo or Youtube. Movement...especially grass is horribly pixelated. Please fix this dji!

Lance, please post an example. I feel I am having the same problem too on my first real world test. However, I have watched many online tutorials of experts and they suggest turning the sharpness down to -2, and I will try that. With other cameras I have owned I have seen pixellating and aliasing if the sharpness/detail setting is too high. Keep in touch with me on this.

Definitely film at -3 sharpness and add in post as necessary.
-3 movement looks much less pixelated in my tests

I'm fighting the same problem.

Recorded in 4k 24fps, exported from premiere pro using YouTube 1080p preset w/ max depth/render quality. CBR at 8Mbps which is what YT recommends. Default settings on the Osmo.

I've seen 1080p videos look much better than this.

Interesting that the backlit footage at the beginning doesn't look as sharp as when you spin around 180 degrees at :16 at which point the footage looks good to me. I always shoot 30p for additional crispness.That said, I have noticed my footage looks better when playing either in FCP or in QT Player rather than on Vimeo, I don't know why. I am used to uploading 1080 so maybe there's something extra we need to do when uploading 4K? But after :16 your footage looks good.

Let me see if I understand you correctly: when you look at your footage locally e.g. on your PC/iMac it looks OK -- but it's not OK once it's been uploaded? Is that correct?

For me, it looks better on my machine than YT. Obviously YT compresses it.
Additionally, I think shots of trees/leaves are the toughest for the Osmo to handle.
Maybe I'm just more critical of my own footage, but I feel like other people's 1080p Osmo video on YT looks much less pixelated.

Me too. My footage looks better when I play it in FCPX or drag the file into QT Player than it does on Vimeo. However, I have always had great results on Vimeo so perhaps we need to understand our export settings better? Something different about this? This is my first 4K experience plus my first FCPX export experience.

A combination of things is happening here...

1. Wide angle lens means more information is captured per frame than a regular lens.
2. Everything is in focus with Osmo, again this is more demanding for youtube compression.
3. Trees are very detailed and therefore difficult to compress.
  --- take a look at similar wide angle video from other video cameras: for example: youtu.be/wuTlkLo2DKs
4. Osmo is quite sharp by default. Try reducing the sharpness in Osmo settings.
5. Osmo lens is not super fancy like an X5, or DSLR. More noise will exist in the image, adding to compression difficulties for youtube processing.
6. Upload 4K video to youtube, apparently this will result in better quality 1080p video conversion. I have not tested this claim myself, but people were saying the data rate of resulting converted 4K video was higher than when uploading a 1080p source.
