Hi ff22,
Having no documentation - I needed to Crashcourse the software in a Cut and Try way - Steep learning curve that got easier and easier as time went on.
SO heres what I learnt (the hard way) - to create VIDEOS with Live Telemetry in Dashware
---- lets assume you know very little about loggers -
* all loggers (GPS and drones etc) collect between 1 and ~15 Samples of data per second- There are up to 100's of types of Data collected (ie Latitude, speed, distance)
* These files are stored in different ways, DJI may use .Txt or csv - Litchi likes csv, older GPS devices may use gpx - etc.
Most of these files can be viewed in spreadsheets like Excel with the Titles on the top - and the data, seperated by commas, on each line below
Each line below the heading is a Unit of time.
* each type of column of info is given a Unique Name for that column of data - depending on the device (eg for 'Height above Ground' on one device - may be called ALT [above Takeoff] ) on another.
* These columns of data are collected from various sensors on the vehicle ie barometer, GPS, compass, speed gauges or spinners etc - at say 15x per second
* Dashware uses this stream of numbers to create certain effects on each GUAGE that is used- Lets say a BAR Guage for Altitude will show a Blue 10cm BAR, for 100m height and if the drone is at 12m alt then it will show 1,2cm- Lets Call this Gauge 'ALT-BAR'
The idea is to synchronize the Entire trip of say 20 minutes - (of Video) with the SAME 20 minutes of DATA collected (recorded 15x lines per second)
Don't worry too much about this concept - Dashware does it very well !
Dashware will do the synchronizing as long as you present it with start and end points of the Video - which visually looks like the start and end points of the data.

OKAY - so heres the tricky Part (at first)
---------------------------------------------------------------
As we said above - each file from a different device calls its data by different names. So the trick is to Look for the 'right' column in the logger file - which will match the same DATA for the right (dashware) gauge.
In our 'ALT-BAR' (gauge) above, we clearly need a height in meters above something- You need to see what these are called -
A drone for example collects:
a) Height above sea level (in m or ft )
b) Height above ground (in m or Ft )
c) Height above takeoff (in M or ft ) etc
Your Job Now - is to reference the GUAGE input - to the Logger's correct column Heading - per each guage. Sometimes a Gauge can have 2-4 inputs (like ALT, Distance and Heading) - to show multiple changes in one gauge.
That's (in essence) the story.
Heres the cool Part - (Wait for It)
Once the hard work has been done … and set up for your environment - ...
… then its done for all future flights and videos to be used again and again.
ie
- The video size (you often work on)
- The Telemetry you want to see - used in the Multip[le Gauges -
- the File type (DJI Go4 or Litchi -= has different file types - but you can standardize them with Airdata UAV download of a CSV )
===========
So in answer to your Question - Is it easy to setup - the Answer is a resounding NO !
However once set up - Like a Computer program - … Its INSTANTLY available for Future - for your setup. So that answer is YESSSSS ! - for reusing the setup on future missions (Very Easy)
Also if ur creative you can MAKE amazing Gauges of your Own - with some Thought-

FINALLY you can just EXPORT your VIDEO with the overlays of Guages- or alternatively you can export a background of BLUE or GREEN behind your gauges instead of video - which will create a GREEN Screen Alpha type Video to import with your Original Footage - into your favourite editor (then just Green screen (chromakey) out the background for transparency-
--- PS the more I typed the more I realised that you should have some computer background to do all this- but nothing too hard for the Drone Pilots who read these pages … !
ANyway hope this helps - Iv had fun playing with it -
