Taking still photos in succession

[offtheback]

Hi All-mavic 2 Pro set to JPG+Raw Sandsik 64 GB Extreme UHS-1 Class 10 UHS 3.After I take a still shot,shutter 1/100 or faster it takes 2+ seconds before I can take another.When I set it to 3 or 5 in burst/sequential it takes those quickly but I have to wait maybe 5 seconds before I can take another photo.Is this normal or do I have something set wrong?

Digital cameras take a while to process RAW and burst. I had a DLSR that would take a minute to process a minute long exposure. The more expensive the camera, the shorter the processing time.

I am sure someone will jump in with actual M2P experience with appropriate suggestions but generally, that is how it works.

That's normal, takes time to flush the buffer to memory.
You'll save some if you shoot RAW only instead of RAW+JPG.

This is completely unrelated and was dark frame subtraction, can usually be disabled at the cost of more noise or smears.

Your drone has very little buffer so you have to wait for the files to be processed and written to the SD card before being able to shoot again.
If you shoot JPG only, you'll have less time to wait.
With fast moving subjects that's the best way to go.

Its a slow camera and definitely not a DSLR, even shooting jpg mode only takes time. Tried taking successive jpg only shots while moving around a outcrop to make 3d images of it and had to stop between shots, and each jpg file is about 14mb, no wonder why it is slow.

I will try raw only.The raw file is 40 MB-quite large for a 1" sensor.Maybe it's the geo location info stored with it?Looks like the Mavic has a very small buffer.The odd thing is the ability to tkle 5 shots immediately in a burst and then the buffer takes more time to clear of course.Thought I'd be able to fire off 5 shots myself which would be slower than the burst and then wait longer for the buffer to clear.Make sense to you?

2 bytes per pixel is pretty standard for uncompressed RAW. Geo info takes only a few bytes.
Most cameras don't queue writes, whether taking a single shot or bursts they wait until all the data is written before being ready for the next operation.

My high end cameras do clear buffer asynchronously, but then they each cost more than an MP and they don't fly...

Thanks Kilrah.Raw or JPG only take about the same 2 seconds before another shot can be taken.Raw+JPG takes about 3 seconds.Still curious as to how 5 shots can be recorded(in about 1 second)and then of course takes longer to clear buffer but can't press but every 2 seconds on single shot.I have a Canon point n shoot that's much quicker.

My high end camera flew briefly once when I dropped it.

Surprisingly JPG is about the same time delay.Odd since raw is about 40MB and JPG is about 9 or10.Something else is in play here I think.

JPG has to be processed and compressed first before storing it, RAW is bigger, but perhaps does not take that time preparing it for storage?

Yep, on the RAW the processing only has to run on the 960x720 low res preview.
