Currently have the x5 but already eyeing up the x5raw for the future uses but to be any use in tv / film it will need to do 120fps to get slowmo actions shots. Think sports etc. a rally car skidding on a muddy corner.


I know the sensor can do this as the GH4 which uses the same sensor does 120fps.

Please bring it out on the x5raw & hopefully the x5 too.

   I have an X3 camera on mine, and with the latest DJIGO App ver2.5.0, I noticed that a setting for 120fps is available under 1080p. From your comment above, does this mean that its selectable but the camera will not record at that rate? I understand the topic is X5, but I currently have the X3 mounted. Thank you.

In regad to the inspire-1 with the x3 camera, starting with firmware v1.5 it shows that 1920x1080 @ 120fps is available as a selectable option, BUT if you try to record in that setting it crops/magnifies the camera image significantly and records at only 30fps and at a very low bitrate producing poor video.  It is a shame tha DjI never explained this to anyone in the release notes.

Are your excellent results obtained using the x3 camera on the Inspire-1 aircraft OR do you obtain these results when using the Osmo.  I heard that the 120fps works well on the Osmo, but it does not work on my Inspire-1.

It is definitely NOT normal.  It is my belief that this feature of 120fps is at the current time, for the Osmo only since the Osmo (with the included Osmo camera) advertizes recording 1080p @ 120fps and that DJI has once again messed things up by trying to control too many different devices with one App and released firmware that was not quite right.
If you compare the clarity of the video that you are recording with the x3 camera on the Inspire-1 at this 120fps setting with video recorded at 60fps, you will see a dramatic difference in image quality, and that is aside from the picture being dramatically zoomed in.
You record at 60Mbps with the 60fps which is 5x more image information being recorded than you are getting with the 120fp at only 12.5Mbps.  For me the 120fps it is completely useless in its current form.
Of course when I sent an email to DJI about this, I got the usual NO Response.

A solution could be a burst 120fps mode? Although on the x5 / x5r it would be best to shoot full 120fps until card is full or battery is low.

DJI should just hire or borrow panasonic / sony engineers or maybe contract out the firmware. Having said that I'm very happy with it at the moment.

-- Edit --


Just looked up about the panasonic gh4 which I beleive the x5 is based on. It certainly uses the same sensor. It shoots at up to 96fps then you choose a framerate to output at i.e shoot 96 output 24. That may explain the 30fps your getting when using the 120fps setting?

I'm not sure I understand, are you saying the Osmo camera is different on a hardware level to the Inspire 1 camera? I know the gimbal is but I thought the actual recording hardware, sensor etc. was all the same.

I get the same results when it's attached to the Osmo handle as when it's on the drone and the same memory card is in there, it looks zoomed in on both. Also, 120 fps mode outputs as slow motion video on my phone, too. I thought that was normal... It captures 120 frames per second but then they get played back as 30 frames per second so you get 1/4 speed smoothly, that's why they make those million-fps videos, to show stuff in super slow motion.

I don't have the Osmo and I am no expert, but according to the DJI Osmo spec page, http://www.dji.com/product/osmo/info#specs , the OSMO CAMERA can record 1080p @ 120fps as a native resolution.  The spec page of the Inspire's x3 camera nor the x5 camera does NOT advertise that setting so I do not believe that the x3 on the Osmo handle will properly record at 120fps.
I would think that a camera made to shoot at 120fps would do so normally & NOT with a zoomed in image that only shows up as 30fps with a super low bitrate.  It is not up to the video file to slow itself down to 30fps, that is the editors job in post.  A 120fps video file should record & play back at 120fps and it should also record at the top bitrate of the camera sensors processors which is about 60Mbps.
I believe that the firmware that DJI uses in the Pilot App to control so many different devices has some errors in it and that is causing this problem.
I have been a beta tester for DJI on several occasions and still got no response from them when I sent them an email about this.

Are you sure this isn't an industry thing? I mean, GoPro 3/4 can record at 120 and 240fps but the video plays back at 30fps, I'm not sure what the bitrate is. My phone can also do 240fps at 720p and it, again, plays back at 30fps. What would you gain by editing to 30fps in post? You can still switch 30fps to 60 or 120fps in post.

Isn't the point of that to see slow-motion video? I mean, given that the GoPro and Osmo seem to be aimed at action and sports shots. If not, maybe I'm missing something.

The zoom is what bothers me, I'm not sure what that's all about but I wouldn't be disappointed with the video quality at 1080p 120fps if that's the quality we get. At 120fps, each frame gets half the exposure time of 60fps and that's the compromise for seeing slow-motion shots.

The whole idea of recording at 120 fps is to get super smooth video of fast moving scenes and to be able to slow it down in post if you so desire.
If I start with a 120fps video clip on my time line and I wish to slow a segment of it down to ½ speed, then that part of the clip will render at 60fps.  Likewise, if I choose to slow a portion of the video down to ¼ speed, then that part of the video will render at 30fps.  
The camera recording the video is not supposed to be cropping anything in the camera, nor giving me a super slowed down 30fps frame rate in the raw footage.
I would bet that the Osmo camera records the actual video file at 1920x1080p @ 120fps like it is advertized as doing and NOT the way the the x3 camera is implementing that setting.If someone here has an actual Osmo camera and can test this, I would be interested in hearing from you.  If the Osmo camera does record the improper way that the x3 camera records 1920x1080p 120fps video then there is someting wrong with DJI's camera firmware that needs to be fixed.
Maybe one of the DJI experts could chine in here.........

From what I have read on the Osmo, DJI are calling it a change of FOV for slo-mo. It is probable that with the limitations of the hardware, software, battery, etc. that they simply cannot capture full frame/full sensor images at 120 fps. Thus they use less sensor pixels, and deliver a 30 fps pseudo slo-mo. I think it's important to remember that the Osmo is an inexpensive camera. Much of the price/cost is in the gimbal. My Nikon can shoot only 720 p at 60 fps. My Panny pro vid cam, a couple years old, cant shoot 120 fps. I really think, like on the iPhone, DJI is simply putting this pseudo slo-mo on for general consumers. Maybe someday they can pull it off for real, but doesn't seem likely with the current hardware.

I confirmed today with my friend who has an actual Osmo camera and it's the same, it outputs at 30FPS. I don't see the problem with that, there's no difference between having 30FPS where each frame was actually taken in 0.25 seconds (for 1/4 speed) and then you can speed it back up to normal speed at 120FPS and your bitrate would go from 12.5 to 30.

Maybe the sensor just isn't capable of recording at 60Mbps with such short exposures or maybe the CPU isn't powerful enough to do it at that speed, I don't know.

Again, my issue is with the cropping/zoom (and it is the same with the Osmo), why does it do that? Is it deliberate to make it easier to see what you're trying to film (like a guy on a skateboard 20m away from the Inspire)?

What you say there about using less pixels makes a lot of sense, if instead of taking the full frame and reducing to 1080p it only took the central 1920x1080 pixels then it would look zoomed in as less of the lens would be used... You'd also lose some of the... I forget what it's called... Light averaging? Where it can sort of combine pixels nearby when recording at less than full frame to get more light data... But that obviously takes more CPU power and time to do.

It is simply a matter of miscommunication, labeling.  It would be clearer to me if DJI would just call this option "Slo-Mo".
Here's an edited clip of a "120 fps" capture with my I1:

Since this forum will only allow me to quote one person at a time, my response here is actually for nwhit, Hterag and Movin on.

It appears that what you guys are saying is pretty much correct.  I did some testing today and shot a short clip at 1920x1080p @ "120fps".  As I stated earlier, the clip was recorded at 30fps at a bitrate of 12Mbps.  Playing this clip back on my computer it did play at ¼ speed of a normal clip and at about a 100% zoom rate, however the image quality was very poor.  It was comparable to 640x480 standard definition and definitely NOT up to HD quality.

I next put this clip on a timeline in Premiere Pro and increased the speed by 400% to bring it up to the speed of a "normal" video clip only to find no change in the same poor image quality.

I next put this same SloMo clip in the timeline and this time added a lot of sharpening to it.  Only then did it start to look slightly better, more like a poor quality HD clip now.

I next took another clip that I recorded today at the 1920x1080p @ 60fps setting.  This clip was razor sharp & clear.  I put it on the timeline and slowed it down by 50% (half speed) and then by 75% (1/4 speed) and found that they both looked great!  They were 100% better than the crap that the x3 recorded at 120fps and without the zooming!

In my humble opinion DJI should not mislead people into thinking that they are getting a 1920x1080p recording at 120fps because they are not.  I know that I will never use it in any of my recordings, but I must say that in the video that "Movin on" posted it looked better that mine did after I sharpened it in post.

Time to move on........

I am having the same experience. 120fps is actually recording at 30fps (at about 12 MBps)   It looks terrible.  Not as advertised.  And unusable.  
DJI?  Anything being addressed here?  What does your R&D department find?  
Please explain what the heck is going on.  I so want to love this camera.  ...But the more I use it, the more I find it does not do what it advertises to do.   
1)  Is it a firmware issue?  
2)  Can we expect it to be fixed, or should we assume it will never really record 120fps?
3)  And why the silence?

Please do not tell me it is  not an OSMO issue.  

This is very frustrating since they advertise 120 fps. Why even include a setting of 120fps in the first place if the quality is horrible and it still only records at 30fps.
DJI- Can someone please explain this? There are many people online across the various forums complaining about this.

Tested this today.   A setting of 1080-120 will record at 120 fps.  When you play it back in Quicktime, it plays at 30 fps. This gives you 4X slo-mo which is what 120 fps is supposed to do.  The cropped file is a trick that DJI came up with because they probably can't push 120 fps at 1080 full frame  thru their current processors. Your getting 1080-120 but not full frame or high bitrate.

So are you guys saying your shooting 120fps on the X5??? because I'm not seeing the options?? Help me out.

Any update on this? Is 120fps coming to the x5??

My X5 does not have 120fps on my OSMO or Inspire.

Here is a test I did using 1080 120fps, I've noticed the quality is definitely suffering...

I've just tried selecting 120fps in the DJI GO App version 2.8.5 and I can now see the option under 720 (Video Resolution settings), and it is called 1920x1080 SLO (presume this is it. However, it is not selectable, it's not greyed out and can press it but no tick appears. Also no option for Slo Mo on the front screen of the App. Have I missed something? Has this option been removed or is something up with my Camera or the App? Thoughts please DJI Tim.

DJI have done the correct thing to default the playback to 30fps. The whole point is to have slow motion. You do not have any choice but to make it slow motion, unless you conform down it to 30 or 60p to play in real time, which would delete frames.

If you really do want it to play back at 120fps real time, put the footage on a 120fps NLE timeline and conform it to that framerate.
