Does higher bitrate make any real difference.

I haven't noticed any real difference even flying FPV . Just wondered how others are getting on.

Hi there,

Thank You for reaching out. We are truly sorry for the inconvenience you are experiencing. High bitrate recording is only effective in video, Super Night, and slow motion modes.
* This function is supported after the firmware version is updated to v01.01.05.10.
I hope this information has helped to clarify your inquiries. If you have any other questions, kindly let us know. Thank You!

It does make a difference but it's still not high enough in certain situations. FPV needs even higher bitrates to be saturated IMO.

I did tests on a motorcycle at 100 km/h (I drove the same stretch of road twice with different bitrate settings) and realized that the high bitrate option doesn't change anything except the file size.
But a much bigger shame is that my old action camera from 2016 gives a more detailed picture at the same bitrate.

It did improve the image, I see less artifacts now. I would say it was a 20% improvement in image quality, you can see my comparison in the other thread this was discussed. This small gain is expected because bit-rate and quality doesn't have a linear return. With the current bit-rate the image can be improve even more by allowing a lower sharpness.

The image quality will probably not be that much better.
I do remember with the Mavic Pro that we got an update that bumped the bitrate which was noticeable, but those were the low bitrate years, so bumps were significant.

In the past, I’ve rendered videos at lower and lower bitrates just to see at what point, things start to look bad. What surprised me was just how low I could actually go with mostly still video. Moving the camera around was another story. At really low bitrates the picture went blocky with leaves and movement. Just by raising it a little, the blockiness became much less significant all of a sudden.

The old GoPros looked great most of the time until you walked past hedges and the leaves all became moving square blocks!

So a lot of the bitrate thing might be more to do with movement I think, rather than pure picture quality. That may account for varying attitudes towards bit rate for video and why some see it more than others.

These days, I render at ridiculously high bitrates really. Storage space is cheap so I habitually keep it high and don't think about it. It's not really discussed that much either....

Compression after export is also a major role when it comes to quality of a footage. There are some (atleast used to be) editors that could not export it high quality so shadows and dark areas would always have compression artifacts. And having lower quality footage to work with, will just make it looking worse.

I find its more then just a camera, it matter t everything you own to get the best quality that said

When bitrates where at 30mpbs and they increases to 50mbps an increase of approx 70% it was noticeable, but now increasing from 75 to 100 is not so noticeable except on file size and storage. Hardware storage is not so cheap when saving 4k 60fps video and cloud storage will be lost forever when we’re gone unless someone takes on the mantle of paying a monthly rental charge and I cannot see that being a welcome inclusion to someone’s inheritance

Nowadays a 8tb hdd is like 100$, videos doesn't need to be stored in a ssd. My current workflow is recording using high bit-rate and dlog-m. In post I apply the lut with ffmpeg and encode down to 60mpbs using nvenc. This results in a better looking image than doing the same with standard bit rate while also having a similar file size.

Thanks for the information, not sure 8tb would cost as little as $100 this side of the pond .

Yes my bad, 100$ is for 6tb which is still a lot. Last I bought was 8tb for 130$ couple of months ago. With some quick math using my workflow described above I can store more than 250 hours of footage or 125 hours if I don't reduce the bit-rate when applying the lut.

Well, storage costs nothing like it used to so it’s no longer such a big issue these days really.

This is an HD https://www.amazon.co.uk/Seagate ... mFtZT1zcF9hdGY&th=1 £153 for 8 tB in UK.

I’m currently using a Samsung SSD which is probably a bit safer and seeing that they can be bought 1Tb at a time, it’s not that big a deal.

My relatives will only need to is plug one of the drives into a TV with nothing online to download and no rental fees!!!

I compared between standard and high bitrate and there is a difference which I observed under "Supernight" mode when the surrounding is dark lit and the subject is moving. High bit rate has less artifacts and for some reason, less jitters. ...I had the EIS Sports option turned on as well rather than standard during these tests. Just sharing as I know opinion differs on this subject.
Under video mode, and if the surroundings are bright, high bit rate has very little effect on quality which I believe some of the folks are experiencing here. Perhaps, DJI may want to have the option to turn this off or on at the "mode' level rather at system level, so that users can have the option to select standard bit rate for the various custom set modes. I typically have several custom video modes depending on the EIS I need e.g. horizon balacing or rock steady, FOV and shutter/ISO settings.
