Nice! Extracting the max as usual  Video looks great to me. Not quite sure about the G bubble and how it relates to actual action, but speed is good and will make a useful comparison for future runs. Loton Park looking unusually sunny & parched. If the car has survived that long hill in those conditions it’s probably sorted!

Excellent video Hamish. And the car sounds fab too

John if yours is a hero 5 “black” you should be able do it.  this tells you how the GoPro has gps built in if enabled (a 5 black or newer) the detail is extracted using and App( rather than desktop) so phone or tablet app called GoPro Quik that’s free. i use Apple products ( they seamlessly link to each other MacBook, iPad and iPhone) and links to the GoPro by Bluetooth/wifi. thus I use iMovie which is very user friendly.    alternatively you can use  Videopad which is similar.

Indeed it is, Hamish! How very dare I for even suggesting it!   I watched again and it's clear from the start! Are these from an add-on app to your GoPro?     I have one, 'encouraged', almost required, in CSCC - so much for 'non-contact' motorsport!  Mine is a "Hero 5". And, if I may, what do you use to edit your videos?  Those I've tried - editing a 40 minute race is essential! - are clunky to say the least. John

Sorry John. Think it’s your end. Ok here and no other comments on a quality issue !?

Great Video Hamish! The graphics work really well. Looks like you had a great time

Fantastic!  All you need is a head up display! Initially blurry (low definition?) it went crystal clear at the last corner!  Or was that at my end?  

Here you go its seems to have worked and amazingly I seemed to have worked out how !!!  

Saw this Larson cartoon... Which reminded me of this.... (antonym?, antojoke??)  

Thanks guys i may have worked out how to add basic GoPro telemetry to the video loton appears to have a good gps signal - unlike SHELSLEY ! so watch this space as I need your opinion if it adds any enjoyment ? or clutters the screen that the speeds aren’t that impressive after all ? be honest - but gentle.    watch this space
