Another 4K test of the Irish Sea.

This one was sent to me by SJCAM. I've already bought two of their other cameras so thought it would be interesting to look at. It claims to be the full 4K sensor and they're one of the better cameras, but I've no plans to use it on my bench.

I really don't like these Camera's, Most of them are only a 1080p or 2k Sensor if you lucky then they are intupulating 1080p to 4K. I have been sent a few for review, But never did any Video reviews due to the poor quality! Please don't use this for your videos, You 1080p footage is brilliant since your last camera swap :) What ever you use currently is brilliant quality :)

"So, Mr Mitchell, you say you were lurking in the long grass on the dunes testing a camera, were you?" "Yes, officer"

With my system 4K is tricky but 1440p looks lovely.

Fixed focus camera.

Very nice downsampled to 1080p on my teevee

That could easily be mistaken for Ocean City NJ, not far from where I live. NICE

I can't be sure - without some flames, smoke or some spudging going on. (looks good although without strong light it's hard to know if it's going to handle color well.

Me too! I would absolutely LOVE to live in Scotland, but alas, I'm stuck in the worst drought we've had for 100 years, with 40° daytime temps. :/ I really am SO over this hellscape.

lots of artifacts and an bit out of focus especially the center distant reeds.

I was getting odd areas fluttering like a previous post mentioned. I watch everything set to 720p since my laptop is 1366x768 and it is not worth the small improvement of 1080p I did try running it at 4k and it was buffering on my talktalk connection at 36Mbps Set me reminiscing about Port Soderick and our Stonyhurst dive club visits on the ferry back in the 1970s . Thanks Clive for all that you do John

This is indeed true, however, it would be much 'cheaper' (bandwidth- and storage-wise) and more effective to increase the frame rate of the 1080p stream, at least for scene prone to motion artifacting, like this.

One advantage of uploading at 4k is that viewers then have the option (on PCs, at least) of watching the 4k stream even if it's down sampled to a 1080p screen, which results in much higher quality than just watching a 1080 stream because there's comparatively less compression going on. That waving grass is a prime example. Setting my 2560x1440p phone to the 1440p quality option greatly reduced the compression artifacts of the grass over watching the 1080p stream. How much any of that will matter will depend on the scene, of course!

These days I use a Moto G4 to record and upload my videos. Apple's "updates" rendered the iPad unusable for the task. Over time resolution and frame rate will increase, but file size is still an issue for uploading, even with a new 4G data connection.

Big Clive

I may try it at the bench, but the angle is so wide it will cover too large an area.

Big Clive

Hmm, the motion artifacting on the grass seems to be pretty bad, but obviously it's still a huge improvement over the ipad (you are still using the ipad to film your usual videos, right?). Is there any way at all that I would be able to twist your arm to start recording and uploading at 60Hz (1080p60)? It will increase the stationary detail of objects by giving YouTube's compression algorithm more frames to distribute the compression errors over; but it will also make the videos quite a bit smoother, which will make the video footage fit even better with your calm, soothing voice (okay, I see how weird that sounds but seriously, ask anyone on here, your whole teaching style is so chilled and soothing!). It will also, obviously, help to reduce aliasing from PWM modulated LEDs, giving at least a somewhat improved perception of the flickery-ness (or lack thereof) of lighting solutions.

Caww... caww.... looks bleedin' freezing. Fast movement doesn't seem to be the camera's strong point. But perfectly adequate.

I'm sure the file off the camera would look amazing, but unfortunately YouTube compression destroys this one where the grass and waves are moving so much

Nice scene. Wish I were there instead of here

Nice image quality. But what's it like at the bench?
