To those who think this can be done automatically, no such luck. Everything is manual and it is a very repetitive process.
First, we need to extract the data of the dive.
Go into Shearwater Desktop, select your dive and go into File->Export Dive->CSV
Shearwater will ask you for a directory to save the data to. In that directory you will find a csv file that you can open either with a text editor or excel.
Here are the columns that I used for the video:
Time (seconds), the shearwater internally save the data every 10 seconds, on the display the TIME is in minutes.
Depth: This translates directly into the DEPTH field
FirstStopDepth: translates to STOP
TTS Mins: translates to TTS field
Average PPO2: translates to the Gas PO2 field
Current NDL: translates to the NDL field
Fraction O2/FractionHe: permit to reconstruct the gas and the O2/HE field
In Final Cut pro, I created 2 titles that mimics the shearwater display (available here), Why 2, because the shearwater will change the color of the gas, when there is a better gas that can be used.
Now the boring part:
You have to sync the data that you have in the excel with the movie. What I do is that I use the moment I look at my shearwater in the dive to sync it the excel data. When this is done you can go backward and forward from that point with the excel data.
I do a title every 10 seconds that is overlaid on top of the video, in each title, I look in the excel to find the corresponding data from the timestamp and I update one by one every title.
Have fun!
