Am I right that the Mini 4K has 100 Mbps at those frame rates?

Yep, you’re correct. The DJI Mini 4K has a max bitrate of 100 Mbps.
Honestly, I don’t think there’s much difference between 130 Mbps and 150 Mbps for a drone. It matters more for action cameras or FPV drones since they fly faster and closer to objects.

But we’re talking about a drop from 70 to 90 Mbps for 4K 60 and 4K 30. You can’t assume how people will use the drone.
@Peyton
They could really benefit from adding support for AV1. I’ve been rendering FPV videos at 70 Mbps AV1 and the quality is just as good as the original 140 Mbps H.265.
But what’s this bitrate change really going to do?

It could lead to a loss of detail in fast-moving scenes or those with a lot of small details.

Funny thing is, I’ve watched a bunch of Air 3S videos on YouTube, and the footage actually looks more detailed than I expected, even after compression. Seems like DJI might be encoding H.265 differently now. At the end of the day, real-world results are what matter, not just numbers.

Nothing, really. The new format doesn’t need as much bitrate to deliver the same or better quality. People keep bringing this up.
@Ashton
That’s what they said about the Action 5 Pro, and its bitrate looked terrible.
@Ashton
You can say it as many times as you want, but H.265 is still H.265. Lowering bitrate by 60% is definitely going to hurt detail in fast-moving or detailed scenes. Stop spreading misinformation.

H.265 is a big standard, and there are many ways to encode it. DJI might have found a way to maintain quality with a lower bitrate. If detail is really lost, it should be easy to show.
@Flowky
If you really need proof, here’s a classic example: Tom Scott’s video shows how low bitrate can affect detail, like with confetti.

But DJI has new hardware and encoder tech. It’s not the same as Tom Scott’s example. Different encoding methods give different results.
@Flowky
Yeah, that’s what they said about the Action 5 too. How’d that turn out?

Actually, if you tweak settings like DLog, ISO, and shutter speed, the Action 5’s footage can look great, even at lower bitrates.

So you think DJI would make a new drone with worse video quality? They’ve said the new algorithm gives better quality at lower bitrates.
@Ashton
So you’re saying they invented a new codec that’s still called H.265? Sure, sounds like a huge leap in compression technology… not.

DJI isn’t going to ruin its reputation by downgrading video quality on newer drones. They’ve never done that before. The Action 5 isn’t the same situation.
