It was painful to sync data to video in the past for me too. The trick I learned back when my data was from OBD is listening to the engine sound while watching the rpm data channel. It was still time-consuming, but I was getting good results. (those HLT people are just lazy!!!111)
Since I started logging CAN data, which includes a data channel for the steering angle, it became very easy to sync video to the data perfectly. I first approximately sync audio vs video my checking the map, and then I only need to find one place in the data log where I do some quick steering correction (e.g. counter-steering). The whole process takes less than a minute for me now. You can gauge the quality of results in the examples I shared above.

Totally agree, this is why IMO mobile apps such as RaceChrono are superior to PC/Mac software for most people — they make the process of analyzing data between sessions much easier.

To be clear, video, even with overlaid data is not a substitute for data analysis but it can be very helpful "immediately" when at the track.
Just my experience.

I'm sure a lot of people can relate to that experience!
That's why Garmin Catalyst is so popular, despite being a $1000 product with no OBD connector.
