Overlay delay even with 0s

[benybendebou]

Hello,

I tried several parameters to overlay my video. I changed the "Overlay Sync" in the expert configuration until 0sec because the OBD data were a bit earlier than the video.

It's much better now but it has still a delay. The OBD data are approx 0,5 sec earlier than the video. I tried the configure -0,5 but it obviously doesn't work.

Can I tweak in the "Sensor Delays" ? If yes, should I add 0,5 or take off 0,5 to the OBD sensor? It is for now at 1sec.

Thanks

In case data is earlier, video is late. This in turn means video has a bigger delay than configured and it needs to be *increased*.

Any sensor delays except Video are applied during recording and will have no effect "after the fact".

I don't understand, but the best result I got is when I set on 0s for video delay. The OBD is still earlier than the image, but if I increase the video delay, it get worst!

On this one, the delay is fixed to 0sec

And on the one is set to 2sec

As you can see it seems that the video is more and more late if I increase the delay.

Hard to recognize for these short sequences with multiple shifts... A difference of 2 seconds (zero to 2) is huge, adjustments required are typically +- 0.5 seconds or less. You may provide a track day video which makes it easier to recognize. Furthermore this part can be adjusted after the fact and should be done once you have the real stuff.

I understand, I made many tries with +-0,5s steps, and it is oubvious for me that the lower the delay is, the best sync I got.

If 0 is better than 0,5 , I don't understand why I should try 0,2 or 0,3.

I'm a little bit confused with those parameters.

I'll make some more tries.

Thank you very much for the help
