Hi all,

I have a DJI Spark - It's in warranty and also has DJI Care valid.

While recording videos i noticed the video is a bit blurry - like i get a slight blurry wave and then it get's cleared

I'm a bit confused - shall i send it to dji as i have the dji care still valid

can dji give me an upgrade to mavic air if i return the dji spark - I mean is that possible?

Check the focus, tap the center of the the screen while flying. The focus might be locked, if so un lock it.

I don't think DJI Go 4 has a tap focus capability...there is a double tap that locks the exposure...and a single tap to unlock exposure, but I'm not aware of tap focus.

The spark does not focus.  It's locked in to focus at infinity.

Are you talking about what you're seeing on your phone while you're flying or the video that you're pulling off of the SD card?  The phone changes resolution often depending on signal strength.  You can never trust the quality of what you're seeing 100%, because it always looks better when you pull from the SD card itself.

Can you share an example from your SD card with us to check it?

No, DJI don't do part exchange and won't refund your purchase to buy another drone. Can you upload the footage so we can see what the problem is?

Hi all,

thanks for your inputs


Is this the cached video from your phone or the raw video from the SD card?  As mentioned from posts above, the video taken from my phone seems to be a lot less of quality than the video from the SD card.  Although, I have noticed some of my raw footage from the SD card is a little "grainy" from time to time.  I have just chalked it up to being alittle too breezy or interference from the city's WiFi and other electronic interference.

Hi,

I did a camera reset + IMU Caliberation.

I guess now it's ok.

Please have a look at the latest footage.

To be honest, I don't really see a difference between the first video posted vs the last video posted.  To me, they both look good.  The only thing I can think of is maybe the lighting is affecting the picture and you aren't getting the image that you are looking for?  I have noticed that I too get some "less than par" video quality than I anticipate and I am not sure why.  I hope it all works out for you, stick in there!!

How does the focus lock setting differ from auto-focus unlocking it? So essentially locked focus is comparable to manual focus having shallow depth of view?

The focus lock is actually related to the auto focus but to keep a desired focusing not to be changed while the camera is moving, to keep the same depth of focusing.

So that wouldn't be something slightly similar to when the Mavic Pro is set to manual focus?

As mentioned before, Spark is fixed focus so there is no App setting to change that!
