Springtime Phantom 4 flight over a river.  No issues with VPS over the water.



Because of the blurry parts in the YouTube video I uploaded a copy to Vimeo.  The Vimeo upload plays much smoother.

Aloha hummingbird,

     Nice video.

Aloha and Drone On!  

Good jb

Very nice! I'm curious of what causes those random seconds of garbled image every few seconds though...

Nice video and music.

My guess for the garbled images is that the YouTube encoder is overwhelmed by the fine detail of the video and the speed at which the image changes.  When I encoded the original I used a 36mbps data rate and two passes and it plays crystal clear all the way through.  This is about a 50% data rate reduction from the original recorded with the phantom.

nice video, congrats

Hum,

Nice video! Why only 720p? It'd be awesome in 1080p.

Odd as it plays in 1080P for me.

Aloha hummingbird & jerry,

     It played in 1440 for me.  I was going to critique some parts like PAN speeds, but then I realized I was looking at it at 1440.  The artifacts mentioned earlier were also in 1440.

     As I said before, Good Job!  Sometimes display gets in the way of viewing good work.

Aloha and Drone On!

Very nice! Did you turn off VPS before going so low over water?

No VPS is on.   Didn't notice much altitude deviation but was ready on the throttle if required.

Thumbs up for your guts! It does make great shots when you fly low, but I don't feel ready for that yet.

Nice clip. I think you are right about the amount of fine detail swamping the encoder. BTW, is that a paid subscriptiobn to Vimeo? Last time is used it you could not get high definition clips unless you paid.

Yes I pay for the plus.

Aloha hummingbird,

     Yes, it was much better, almost no artifacts, really only the downward tilt to the river and it was much better than the YouTube one.

Aloha and Drone On!

Nice video, and yes much better than you tube... question, I uploaded 2 versions of a video, you tube and vimeo thinking that the vimeo version would look much clear, better, but I think they look about the same. any tips or suggestions on what to do next time?, thank you.

To get a good rendered video nothing beats a high data rate.  The YT clip uploaded had 56mbps single pass.  Surprisingly YT's re-render did not do a good job.
