I use a P4P v2.  I find the yaw, or left/right turning control of the left stick, to be way too fast. I'd like to to have the total range of the movement to be only the first 25% of the current motion control.  Is there a way to set the upper limit that the stick will reach?  I want the maximum turning speed to be less than it is factory set. Is this possible?  The upper half of the speed range is useless to me, and makes gentle turns very difficult.  Would like to do the same for the forward throttle.  I am not talking about adjusting the EXP setting.  Thanks.

Change the value of yaw movement limit in your app.

For some reason I never saw that menu.  Thanks! Regarding braking, sometimes I inadvertently let go of the left stick after a smooth slow yaw movement and the craft jerks back to going straight, ruining my video.  Will setting the braking sensitivity to a lower value smooth that transition out if I move the stick back to neutral too quickly after a movement?  And same with the throttle?  And will a lower value for YAW sensitivity really lower the full speed of the turn when the stick is fully thrown left or right?  I sure hope so.  I need to try this tomorrow.

Aloha Jeffrey,

     Just out of curiosity, why are you not talking about the EXP setting?  What you describe is almost exclusive to the EXP settings.

     BTW, love the ukulele on the beach.

Hello Cetacean, the EXP setting controls the rate of acceleration and creates a response curve for the motion of the stick.  I want to limit the speed at full stick, which is also referred to as setting a limit on the speed at full stick..  Two different concepts though you can adjust each to work together as you wish.  Aloha. Yes, I am Ukulele player and instructor.

Aloha Jeffrey,

     Let me look at the EXP a little later today.  I think there is a way to limit the maximum speed as you indicate.  The EXP does have positive and negative values.  If the negative value (I think) is flat lined, there is no increase in speed beyond the flat line.  But then, you may loose out on the smooth transitions.  You may also be able to use the positive values and slide the end point of the X axis to reduce maximum speed.  Got to look at it.

     This is kind of an unusual request, since most others want the Phantoms to fly faster.  I was stoked to just learn that you can smooth out "SPORT" Mode!

Cetacean, how many videos have you watched that have real jerky moves and quick annoying turns? Most all of them!  The yaw stick is so sensitive that the only part of it that I want is the first 1/4" of movement or less.  But, it is difficult to move slowly to that point and then hold it there a bit before slowly moving back, all with your fingers.  I want that short range spread out over the entire travel of the stick and have the turning motion to be much slower when the stick is pegged. EXP will not do that.  I tried to move the endpoint of the curve but it is fixed and you can only adjust the curve that ends at FULL speed. Not for me.  I'm sure many people wanting professional results will want that was well.

Aloha Jeffrey,

     What you are saying can still be resolved with EXP.  I do understand the problem you describe and it is somewhat of a pet peeve for me.  Most of the problem is resolved with EXP but there are other options that can also help.  The slow YAW rotation of the camera probably has the most options available in the whole DJI GO 4 app.  Have you tried Tripod yet?

     I will get back to you tomorrow.

Tripod does not solve the problem.
Tripod reduces speed of all motions, but yaw.
I've had the same problem. Yaw speed is much too fast for nice video shots.

Depends on a drone which you fly with. MavAir turns (yaw) very quickly. Too fast for the nice video and I must cut off all those turns in post p.
While the Phantom can be turned L/R very smoothly, you just need to control your fingers. Not go without practicing.

If you pay attention to the work of professional cinematographers, you will find that they usually avoid the panning shot like the plague (the equivalent to yawing). In my work, I dso not use it at all if I can avoid it, because of the movement artifacts it introduces.

Aloha DJI_112,

     If YAW speed is too hard for you to control very well, try a Point of Interest.  I have used POI since it was introduced for very smooth PANs.  Just aim the camera straight across and let the computer generate the smoothest PAN you can imagine - and in perfect circles to.  By controlling the radius and speed of rotation, you can speed up or slow down the PAN to suit your needs.

     Interesting comment on Tripod.  I had never noticed that Tripod does not slow down YAW rates to.  When I get out again to test the EXP settings, I will take a look at YAW in Tripod to.

     This Forum has some very talented PAN rotation specialists.  They do amazing work.  Smooth as silk.

Aloha and Drone On!

Aloha andy,

     Have you tried a Point of Interest with the Mavic Air to get a smooth PAN.  Just aim the camera straight across and use the computer to control the radius and speed of rotation.  Very smooth.

Aloha Jeffrey,

     Smooth PANs are an art form and some operators on this forum consistently show extremely smooth PAN videos.  They are very patient and talented.  It can be done.

     Until I can get out and fly, have you tried a Point of Interest PAN yet?  Very smooth.  Just aim the camera straight across and let the computer control the speed and rotation.  Your input is setting the radius and adjusting the speed of rotation.  It works very well.

     Until I can get some testing done (very windy Trades these days), I will not be able to look at the EXP and other YAW options.  But try the POI, it really works well and makes a perfect circle.  Slowest rotations use large radii and slower speeds.

POI is a nice feature that I have used but it has nothing to do with the action that this thread is about.  Finally a few contributors here have recognized that smooth turns and slow yaw movements are a real challenge, but are also very professional looking when done right. Next time I'm out I'll try the Yaw limit setting.  I have actually placed a small ring of open cell packing foam around the stick to dampen the travel motion and help me keep it fixed throughout turns.  Temporary until I get the settings right.

Aloha Jeffrey,

     The wind is still blazing and gusting around here, plus we are getting more rain, so I have not gotten out to fly yet.  Your packing foam solution is useful but it is better to get the electronics working for you as you noted.  (I made YAW sticks to use like your packing foam.)

     Besides the EXP, there are something like three other adjustments to smooth out YAW.  It has been recommended to not adjust the "Gain" unless you have a clear understanding and unique need for that adjustment.  If you do make a bad combination, you can return the settings to "Default".  

     The best thing to do is record your settings when they do what you want.  Then when you get a good YAW adjustment, record it with the others that do what you want.  This way, if you have to restore defaults, you have the last ones that worked for you noted.

     You will probably find some really interesting combinations.  There is one combination that someone used that was amazing and they thought it was a problem.  Well, they solved their problem but did not tell us the combination (after we pointed out that it was a gem!)  I am still looking for that combination!

     BTW, when you get an EXP setting you like, remember you can apply it to "Sport Mode" to, just flip the switch.  It really tames the beast, so much more manageable.

I've made some progress. I set the yaw EXP to between 2.0 and 2.5 and set the Yaw limit (in Sensitivity, to a very low setting near the lower value limit).  I'm also just getting better at being very careful with the stick.  In this sample video I should have used a ND filter to allow a longer shutter speed of around 1/60.  I believe that's why the video is chugging when I am making turns. Still, it exemplifies the professional like pan and turns that make a video easier to watch.

Aloha Jeffrey,

     This video should not have had the "chugging" as you say.  I think the problem is in the recording and / or the editing.  Cut out a clip of one of the turns and edit in different ways that change the video speed so it is real speed when it is exported.  This video was in slow motion, which to me, seemed to make it chug.  Find a combination that gives you a real speed and no chugging.

     What was the recording frames per second?  Did you record in 1080p-60, or 1080p-120?  Try a similar but very slow moving video with 4K and 30 frames per second.  Render (export) it in 4K and 30 frames per second.  You can also try recording it at 1080p and 30 frames per second to and fly slow and smooth if your computer has a hard time with editing 4K videos.  (There are other tricks to editing 4K videos on slower computers, like "proxy".)

     Your flying was very smooth in the slow motion.  If you can fly that slowly and use 4K, you will have awesome videos just using 30 frames per second.  BTW, the flicker rate of the human eye is 25 frames per second.  For smooth video rotations, recording should be at 30 frames per second minimum.  Using 24 frames per second will give you chugging rotations in any film resolution.  Some people like the chugging.

Cetecean,

Thanks for the tips. I am not a video expert by far.  I know the frame rate was 30, but need to keep track of the other parameters.  Truth is, I was moving faster than the vid shows and I slowerd it down in edit, likely creating the problem. One thing I have heard from experienced videographers is that with these drones, the shutter speed should be about twice the frame rate. And, no, I don't like chugging!  I'll look more closely at my editing settings and export settings.  I use iMovie for now...

Yes, fast turn are often annoying, and disturbing to the eyes.

Changing direction of position, to appear smooth and practiced takes just that.

I think that’s why many choose to delete those moves and just go directly to the next scenes or video segments they wish to share...

Nothing good isn’t challenging, or is it everything good, needs effort?, in great video recording/editing.
