"How do I synchronize the video and data so the right values are shown at the right time?
To synchronize, locate a spot in the video that corresponds to a spot in the data. The slider below the video moves through video time, the slider in the Synchronization tab moves through the data time. I find the easiest is to look for where you first start moving in the video. Then locate where the speed first starts going up in the data. Click the “Sync with video” checkbox in the Sync tab to sync them together. Playback your video. If the data looks a little off, uncheck “Sync with video”, adjust, and then recheck “Sync with video”. You can make fine adjustments with the < and > buttons on either side of the play button (below video or in sync tab). By default they move by 0.1 seconds. Holding Alt makes them move by 1 second.

What’s the best way to use DashWare with another video editor, so I can do sophisticated edits?
How to make blue/green screen, gauge-only videos with DashWare:
-Add your video and data files to the DashWare project like usual: synchronize, set up your gauges how you like, etc
-Once you are ready to export, create a new “Green Screen” gauge. In this new, empty gauge add a Filled Rectangle component with the dimensions of your video (e.g. 1920 by 1080). I use a bright, neon green color for the fill. You want to pick a color that you are not using in any of your other gauges.
-Put this new gauge behind all the other gauges in your project and it will cover up your source video.
-Export and now you will have a green screen video with only gauges.
-In your favorite video editor use a chroma key filter to turn the green screen parts of the video transparent and presto you have a transparent video with your gauges
