I've been using Litchi since the first month I bought my Mavic and use it almost exclusively. I'm approaching 1 year ownership and hundreds of flights but still learning the nuances of flight tricks. I thought I'd start a thread with Litchi tips and tricks in hopes that others (and me) can improve flight and videography skills. Hope to keep this thread Litchi centric if possible and I hope it encourages some folks to submit their own refined tips.

I'll start with three that I hope are worthy. More to come if there is interest.

1. Simple orbit spiral. Use Litchi's orbit and set up an orbit (height, POI, speed, etc) but set the height fairly high, maybe 300' and as the drone gets to the set height of 300' and makes one revolution I hold the stick down so it descends at my desired speed until I get to where I want (maybe 100'). This creates a nice corkscrew effect of your POI. Obviously you should know your surroundings and make sure your descent is clear of any tall structures in the spiral down.

2. Waypoint action: rotate aircraft (multiple actions): It is a nice effect the set up a waypoint with several waypoint actions to rotate the aircraft in multiple steps. For example if I want a landscape/horizon 360 degree shot I can set up a waypoint action #1 to rotate to 0 degrees, pause 2 seconds, waypoint action #2 to rotate to 90 degrees, pause 2 seconds, and keep repeating until you're at full circle (360 degrees). Don't forget your initial gimbal angle and you can use whatever increments and pause times. Also don't forget that you can't use waypoint actions on curved path missions (only straight path). I've gotten some nice horizon shots this way.

3. Easier flight track sync: If you use a post production software like Dashware or Racerender to overlay telemetry data on your video sometimes it's hard to sync the video with the telemetry. I always start my first waypoint with some waypoint actions like gimbal angle changes or aircraft rotation changes. Then if there is a problem with the video & telemetry sync it's easier to overlay something like a compass or gimbal pitch display to see exactly when it changes and to sync it at those spots. *note* even in curved path missions you can still set waypoint actions on the first and last waypoint!

Hope this helps someone and inspires other Litchi tips/tricks.

Here's one I've got that I've used many times that is "similar" but not exactly as yours. It's a descending spiral with a focus on the POI at the center of the spiral at ground level:

The difference is this one is all pre-programmed and easily repeatable if needed. But I like your idea and plan to use it as well :)

Wow. exciting thread. I guess ppl are keeping their tips secret or there is a small Litchi audience here.

I love this one, how did you set this up as a program? is it a manually created waypoint mission with curved waypoint paths setting out the 3D spiral?

Another thing I do is to turn on the feature to automatically record upon flight start. Even with the additional video, it's not "wasted" because before I get in position to start the mission I can use that footage to help sync with the Airdata or Litchi (or Mavic) csv file when I'm overlaying data (RaceRender or Dashware). I usually rotate the AC or do a gimbal up/down, that makes it easier to spot in syncing video with telemetry data.

I've used Python to create csvs that can be imported into Litchi Mission Hub, complete with waypoint actions.

There's no neat interface, I just edit the script as required, but the results are pretty good.

Essentially if you can write a simple procedural script that can create a series of [x,y,z] points, then it's easy enough to convert those values to lat long, and then spit out a csv in the right format.

I've used mine to create flat flightpaths for composite aerial photography (i.e. only [x,y] points).

Very nice. How about sharing that one.

Come on BigAl, do tell how you did this one.

For us non-knowing and very interested it would be so great to get a glimpse in how that workflow works - i never used python so i really have no idea how to put that in. It sounds easy.

Could you please share that?

I desperately try to understand how to find a little workflow that is exactly THIS.
But no idea how to set that up. Please assist!
