Recording times for a 480GB SSD

[tammo]

Hi

Just wondered if anyone has a reference to recording times for a 480GB SSD in all the different codec and resolutions. At the DJI website there are a few examples but doesn't cover all the variations..

Many thanks!!

Do you mean this one?

I think that is for the 120 GB drive because it can’t record the larger formats which are missing from that char

This is the chart for the 480 GB.


I looked and DJI doesn’t even publish the bit rates for 24 and 25 FPS so no way to figure it out on paper.

@tammo if you have 1 or two formats you are dying to know I will tell you what the app thinks the capacity is for that format but I’m not gonna go through and do all of them.

Thanks guys. Yes, @Brett8883, that is the chart for 480GB but has alot of missing gaps. I've gone through all the H264/5 runtimes manually by inserting a MicroSD and seeing the recording times for each parameter. Would love to get an idea for the following based on a 480GB SSD:

- ProRes 4444XQ 2040 x 1080 @ 47.95, 50,59.94,60fps
- ProRes 4444XQ 1920 x 1080 @ 47.95, 50,59.94,60fps
- ProRes 422HQ 2704 x 1520 @ 47.95, 50,59.94,60fps
- ProRes 422HQ 2048 x 1080 @ 47.95, 50,59.94,60fps
- ProRes 422HQ 1920 x 1080 @ 47.95, 50,59.94,60fps

The Go App only gives you remaining capacity for the SSD and not remaining recording time which is really annoying as I always get asked how many minutes left on the card.

Thanks!

Oh that’s right I forgot.

According to the documentation changing the frame rate in ProRes doesn’t change the bit rate only resolution changes the bit rate. To a degree this would make sense. Just compresses down to certain bit rate and stops.



I haven’t tested if that is actually the case but the documentation does differentiate with CDNG by saying “up to” instead of “@“ so at least you know whoever wrote that was thinking about it.

At any rate 59.94 and 60 aren’t different enough to make a difference (I didn’t even realize those were options) and 47.95 and 50 would be a negligible difference.
