Thought the image from DJI FPV system look good? Now it will look even better with the higher bitrate setting from the latest 01.00.60 update on 8th of July 2020. The original 25Mbps bit-rate can be bumped up to 50Mbps.
Mbps = Mbit/s, this is the amount of data transferred per second. By doubling the data rate to 50Mbps, the image will look much clearer with more detail, however it doesn’t come without downsides.
Here is some sample footage how it looks. Recorded in DJI FPV Goggles, High Quality, Auto Focus, 50Mbps. This is what I see in the goggles!
How to Enable 50Mbps?
Flash the latest firmware on your DJI gear, V1.6 or newer (how to update firmware).
The 50Mbps bitrate option is only available in FCC mode, in CE mode, the bitrate option is greyed out and fixed at 25Mbps. How to enable FCC mode on your Air Unit or Caddx Vista.
Go to Settings in the OSD menu, under Transmission, Bitrate, and select 50Mbps.
For the ultimate experience, consider setting focus mode to Auto to minimize blur on the sides.
And make sure you select either Channel 1, Channel 2 or Channel 3. If you select Channel 8 (public channel), your bitrate will be limited to 25Mbps.
Downsides of 50Mbps
In order to achieve double bitrate, the DJI FPV system uses two channels to transmit the video signal and therefore the number of channels available in your DJI FPV goggles will be reduced to 3 (plus public channel 8).
If you only see 2 channels instead of 3, just reset your goggles.
This also means more interference to people flying analogue since the band DJI is using is now much wider. To play well with analogue pilots, it’s better to use 25Mbps.
If you don’t normally fly with other people, this shouldn’t be a problem and there is no reason not to use 50Mbps.
As for latency, it seems to be on par with 25Mbps.
However, Audience mode doesn’t work when 50Mbps mode enabled (on the date of publishing).

I have a dji fpv racer on firmware 0103 and goggles v2 on 0106 but don’t have nowhere close to the same look in my goggles as the picture above and can’t find the bitrate option nowhere or get it up on my screen no matter what channel I’m in. Is it possible the drone or goggles is on the wrong firmware?
I feel ya, I can’t find any information on it either. Integra owner here…
Hi people. İ have caddx polar nano hd with dji air Unit. İ cant change max power and 25mbps to 50mbps.İmage quality is so bad. İ upgrade my caddx and google V2. Can someone help me. I choose channel 1 2 3 but doesnt work.What should i do?
Sounds like you are not in FCC mode: Enable FCC mode on DJI FPV System (700mW 8 Channels)
I did everything up there, the thing is that I already select 50mpbs on the DJI Goggles V2 with the caddx nebula pro, the thing is that right below on the goggles sais that is only at 25mbps even when I arm my kwad.
Which channel you are on? It won’t work on channel 8.
I tried and did everything that is explained, I added naco txt file with 1 in it, it doesn’t work. I tried installing the firmware again and it doesn’t work, I tried both 1, 2, 3 channels, the 50 mbps and 8 channels are not available. I don’t know what to do and where I am wrong.
The only thing is that I do not use the official dji antennas but trueRCs with mmcx to sma extension cables.
I have solved it updating the air unit- Caddx firmware.
I have the 50mbps in the V2 goggles but only in the bottom far right corner which is impossible to read and not possible to move in betaflight osd tab.. How can I see this info better in the goggles. Thanks
I’m experiencing the same issue as Anderson above. I’m only getting a max of 25.4mbs. Under the transmission setting i do in fact have 50mbs selected, but 25.4 is the max rate i’m getting.
Have you tried restarting both goggles and Air Unit? Sometimes it takes a cycle to work after selecting 50mbps. And try flying it as well see if that changes to 50mbps.
MAKE SURE you are NOT in channel 8!
you should select either CH1, 2 or 3.
You need to add the naco.txt file to the air units SD card and a it needs is the number 1 on the text file, then restart the goggles only then restart the air unit and you will get 8 channels
So I was able to do all the above, but no matter what channel I’m in (Ch1,2, or 3), the mbps only goes up to 25.4mbps max? Anyone else have a similar issue with this?
50mbps is chosen under “Transmission”. I did have to “Reset all” in order to get all the right channels to be available.
How to you ensure you’re in fcc mode? Dont see that option. Thanks!
Hello, thank you for your nice tutorials and reviews.
I set the transmission to 50Mb/s, but then i just have 2 channels and the public one. Turning on and off is not helping, do you mean you have to do a factory reset in this case?
Does it work with Caddx vista airunit as well?
Yes
Saludos yo tengo el modo FCC se supone, ya que mis gafas si me dan la opcion hasta 700 mw, tengo el vista ya actualice el software pero cuando entro a la opcion de transmision no me deja seleccionar los 50mps no se que hacer? o seria buena idea hacer el paso de cambiar a fcc en el vista aunque se supone ya lo tiene? espero me puedas ayudar
Hi, the bcc mode still work with this update? i used the hack for 8 channels but i’m afraid to update my system and being limited.
other question, do you know where can i find a cli file for my titan DC5 ? i’m looking everywhere but it’s look like nobody share there files. I don’t understand why.
I did my setup myself and my drone fly but why i put the full gaz , my drone is shaking, i think i could get better settings.
50Mbps is a feature of FCC mode.
Contact your vendor for the CLI, or ask in their support FB group.
I have version 1.6 but i can’t enable 50mbit. it’s just grayed out at 25mbit
Need FCC mode.
Hi Oscar, I’m in Canada. 25 mbps is greyed out. Done the hack file in both air unit & goggles. Only channels 1, 2, 3 & 8. i have the 1200 mW power. But 25mbps is greyed out. So cannot change to 50. Is this a region restriction that the hacks do not unlock???
Did you update firmware on both VTX and Goggles?
What does bitrate on the OSD tell you at the corner of the screen? Is it already on 50mbps?
Hi Oscar. Can you share a simple flight with 50Mbps enabled, from the DJI Goggles DVR? Big thank you.
Sure, I added footage sample to this post a few days ago :)
Has the range been effected at all?
Not that I heard of.
