DPReview TV: Why electronic image stabilization works better on your GoPro than your camera

I've always said, I would always want the best IBIS and low rolling shutter even if it meant a little more noise and less DR during video. Its not even close.
I don't want people getting headaches and motion sickness watching a video. And even a some jerkiness during video is a big distraction and major turn off.
If you don't want to pay for a Gimbal, the GoPros or an Olympus ILC is the best option. (although the GH5 is pretty good too)

I AM ALLERGIC TO TRIPODS.

That will be the new thing I say when people go "why not use a tripod?"

I hate those things.

Higher framerates make you look like an octopus with super-imposing images. I too am not 24 fps obsessed but I feel like framerate is a lot like shutter on a stills camera (in fact if you only use say 180 degree shuttle angle, they're all but equivalent). Why would you ever not shoot at 1/4000s shutter? Because water doesn't look still in your brain. Because motion blur makes a car look like it's moving fast rather than parked while going by at 200 mph. Because shutter is typically as SLOW as you can get away with in stills photography. Why do you think video quality would be any different?

Also, no more coffee for Chris.

can someone kindly identify the brand/model of the round lighting equiment that's shown in the beginning of the video?

I wish someone would build an aps-c camera in the format of the DJI Osmo Pocket. A gimbal camera with no viewfinder but a small and high res oled display on the handle. And much less than the weight of a full ILC on a gimbal.

Guys, I’m sorry to say it, but this is THE FIRST fail I observed in videos from you! I do not think you managed to pass through your point(s). (For the other videos, I enjoyed very much what you do — and I enjoy it “professionally”: my job is ALSO about presenting very heavy-weight topics in “deceivingly” simple ways.)

If I understand it correctly, you wanted to:
 • List particular shake-related defects of the resulting video.
 • Specify which of them can be fixed by EIS and which by OIS/IBIS.

With the first item, I feel you mostly succeeded — however, their differences between the types of the defects could have been stressed out a bit more.

I think with the second it was more or less a complete fail. IIUC, NONE of the issues you listed can be fully fixed by EIS — but the explanations of which of them CANNOT be fixed by OIS/IBIS was fully muffled!

Time to time it was sounding as if ALL of them may be fixed by OIS/IBIS, time to time — not. Sorry again to bear bad news!

I don't know about other folk but I found the weird posterizing effect in the studio background very distracting.

I don't know where this "24fps is best" obsession started, but that frame rate is terrible for action and panning.
Playing video at 60fps gives you a closer experience to the real thing when it comes to motion quality.
I'd use 24fps mostly in low light, but the more frame rates the better when looking for realism aka fidelity.

Look at what people are raving about the Apple ProMotion featured in high end iPads where the screen can go up to 120 fps refresh rate for instance.

By the way, you should have mention 360 cameras which are doing amazing stuff in EIS, much better than GoPros

I think you were wrong on some aspects. Like Nigel says, the reason why action camera do better job is mostly because of much wider angle. Also, post stabilization can show better result on stabilisation but I think it has 2 disadvantges that you did not mention: you will loose quality (recompression and/or pixels re-arranging to keep same size) and will also loose side frame rows and columns in order to stabilize image. More stabilization is required, more rows and columns you will loose (in good stabilization) - otherwise row and column count are fixed and not optimized (which could be worse). I think it is very incomplete and I'm not sure you explain reasons but more exposed facts based on experience. I was expecting something a little more accurate and more scientific.

Stabilization algorithm has great effects. Just the software behind electronic stabilisation can makes a huge difference (GoPro could be just better).

About rolling shutter, I can't see the relation with stab...

Stabilization on the gopro max is amazing

The only real reason that action cameras can do a much better job is that they are generally much wider angle and so there is less stabilisation required.

Rolling shutter is easily corrected in recent action cameras, stick one on a model aeroplane and compare on with off and it is obvious that it is not stabilising frame by frame, it does it on a line by line or maybe pixel by pixel basis based on the movement data from the gyro sensor (accelerometer), a short vibration half way down the frame gets canceled out by the EIS.

Software stabilisation normally can't get close to an action camera's internal stabilisation because it doesn't have the gyro sensor data so can only guess at movement on a frame by frame basis by analysing the image, which if there is a lot of vibration can easily go wrong and make things worse.

I have to say the stabilization on an EM1 Mark II is better than on my GoPro. I've seen extremely sharp 1 and 2 second exposures on the Olympus too, something I've never seen on a GoPro or smartphone.
Both the Oly and GoPros are excellent though.

Of course the Olympus has very little rolling shutter too.

Thanks for another great video tutorial Chris. I like the fast and effective tempo you have as it keeps me alert and is engaging to listen to.

Chris... Thanks for the quick class on image stabilization! My only complaint is that I cannot take notes as fast as you can talk... however with it being on video, I can go over areas my brain misses as often as needed :D Again THAHKS!!

Just a bit of a nitpick, you say around the 3:18 mark that "electronic stabilization cannot stabilize rolling shutter". This isn't entirely the case. Many phones and small format sensor cameras apply warping based on accelerometer data in order to remove the leaning effect you get from rolling shutter. Many video editing suites also offer this sort of correction. It's a bit more destructive than other forms of electronic correction as you have to warp the entire frame removing a certain amount of resolution from the final image, but it's definitely something you can correct for.
