Wait are you saying that increasing the bitrate won't increase the quality of the video?There is nothing to be gained from using the 100 Mbps bitrate some people are clamoring for.

An unstabilized action camera like the GoPro would certainly struggle with long GOPs because the inter-frame differences often are enormous. Eventually you run out of bandwidth to encode them or you just don't have the horsepower to analyze the motion vectors in realtime, and the picture breaks up until you get the next i-frame.
But our drones have stabilized gimbals, and our footage doesn't have snow or water droplets flying across the field of view. We can tolerate long GOPs, and that allows very good quality to be delivered at a relatively low bitrate. There is nothing to be gained from using the 100 Mbps bitrate some people are clamoring for. As you said, these are acquisition and delivery formats, not editing formats.
Artifacts are primarily the result of not having enough bandwidth to encode the inter-frame differences. You can increase the bandwidth, or add more i-frames. The latter will often need more bandwidth as well since the i-frames take a lot more space.You want lower GOP frames when you have motion. Have a long GOP frame interval when shooting say a tree, grass, a field of wheat you will get motion artifacts.
In an ideal world we would all be using uncompressed or lossless codecs. Unfortunately that isn't practical, so we have to make do with various compression schemes -- this is why we get 4:2:0 color subsampling and GOPs. Yes, shorter GOPs deal with motion better because artifacts don't compound between i-frames, but long GOPs are more efficient and can deliver a visually indistinguishable image in less bandwidth under most circumstances. Netflix delivers premium 4K content using about 15 Mbps of bandwidth -- granted they use a more efficient codec, but by all accounts HEVC is only roughly twice as efficient as AVC. What makes you think that 50 Mbps isn't sufficient for prosumer drone video?Once again you are proving that you don't understand why you want a higher bit rate (its for image quality)
If you still think that that is what I have been saying then you have reading comprehension issues.You and Tuna are VERY confused as to what makes "image quality" you have a general lack of understand motion frames. to keep saying that a low bit rate and long GOP intervals is not only fine but preferred is both ignorant and a disservice to anyone that reads these boards
DJI and their sycophants are well known for bankrolling trolls. There are also narcissists who are legends in their own minds that write novels on forums believing that people actually read them or give a rat's behind.I wonder who derstig works for, he will not substantiate his claims of working in film/television. His every post is a criticism of all hardware and software associated with the imaging system used on the typhoon, with direct comparisons to DJI. Why he would even look at this class of consumer multirotor as merely a buyer or enthusiast is itself suspect.
He opened with discussion of his use of cameras with bitrates thirty times greater than the typhoon, but now incessantly posts how 60 mbps is wholly adequate, failing to find any issue with a rate that is still orders of magnitude lower than what he ostensibly finds necessary for professional use.
He criticized the lens for not allowing enough information to reach the sensor, but has abandoned that tact as aftermarket alternatives are available and the rumor mill has posited that yuneec is changing the lens on new units.
Now, it isn't an issue with the data reaching the sensor, it's an issue with the codec. Somehow the codec needs improvement because it can't handle the insufficient image data reaching the hardware to begin with.
Such a vociferous, muddled, and chameleonic assault on every comprehensible feature is hopefully bankrolled, because the level of effort is disturbingly high otherwise.

The answer is, don't feed the troll. Until he starts posting constructive advice, or using his extensive experience to help people rather than shout them down, the ignore button makes the forum far more pleasant.
It's a shame, because Yuneec could do a lot of things to improve the platform, and genuine input from real experts could help make that happen. Unfortunately he rubbishes absolutely everything and anything, so who's going to pay attention the one time he actually makes a useful point?
That's interesting i'm no pixel pro. My professional experience with cameras reflects better performance with increased bitrate.I started with panasonic GH2's.. The GH2 shooting at it's native bitrate versus the same camera using hacked software to increase bitrate shows a very noticeable diffeence. Especially where there is movement. Running water etc....Correct.
The codec has a given amount of space (the bitrate) to work with, if it isn't having to throw away any information (or throwing away information that would be imperceptible to the viewer), then taking up more space to encode the video simply reduces efficiency without a gain in quality.
I work in Film and Television and you have seen the products of my work. I also consult for equipment manufactures and cameras and support has been redesigned due to my involvement. 60Mbps can look fine, it will look like a gopro but Yuneec has missed that mark while initially selling us on a 100Mbps camera
In a comparable price range from the Typhoon H and the DJI P4 I like the AUTEL ROBOTICS X-STAR 4K WIFI CAMERA, (ORANGE) a whole lot better for video quality. Just my opinion. From what I see coming out of the CGO3+ is not any different than the CGO3 camera.
Really enjoying my premium, and buying on prime day puts me at 900 for the platform, removable gimbal, case, two batteries, charger, 64 gb micro sd, two sets of props and smaller items. No way I could justify the P4 with that deal, putting on the brakes for something immediately in front of it isn't worth hundreds of additional dollars to me for a small quad that is otherwise similar in utility to the autel, outside of using thinner plastics overall and being stuck with the one camera and gimbal.I was looking at that one too.
What I am saying is that if the codec isn't requiring the full 50 Mbps available to encode the video, then giving it 100 Mbps isn't going to improve the quality.Thats's not true at all and only shows a lack of understanding
