not sure what the issue is then..
was it out of sync one session or consistent across session

if you create a track around the block does that work?
I would remove the app; restart the phone and reinstall the app.

if you can recreate it around the block I would take it to the dealer and tell them it's a warranty issue with the car :-)

sorry to not be of more help

Also I can't figure out this ghost car thing or how the view my squiggly lines data and so forth. I see nothing in settings for this stuff.
Not sure this will answer any of your questions, but it's short so not a huge time investment. Use pause/play to see/read the details:

I had been using this with my 991.1 GT3 and it was ok, a bit spotty as everyone says, but I used it this weekend for the first time with my 991.2 GT3 and it was meh.

First, it worked only 3/4 sessions. I think the VBOX messed up on one part since it didn't even record on the SD card. And secondly, I can't export the videos, it goes through the exporting process and then when it goes to save, the app crashes...

Anyone else have these issues?

Yes, I turn my phone on airplane mode before I set off on the track.

I just got this setup today as I plan to track for the first time soon. I have a GT4...seems to work, did a test around the block and "made" a track. However while the playback of the video within the app is "smooth" the output overlay of the wheel for example is stuttered/stepped on my video... its like the output overlay gets updated every half a second instead of every frame of videos.. any ideas? Maybe it's a limitation of the app. Was recorded at 1280x720 30fps. I haven't read the whole thread here yet...airplane mode sounds like a good idea...but that shouldn't change my export.

@nlpamg When you are saying "exporting" and it crashes... is it actually crashed or just hung? I had some export videos where the export progress bar appeared and then immediately disappeared... but if I waited long enough the app actually finished the export. For others you can see the progress bar as it goes...

So is your situation when you play the video within the app, the wheel motion is smooth, but when you export it, it is not smooth? If the situation was it was chunky within the app and in export, I might guess the phone had problems using 100% of the cpu/grahics card or something like that...where maybe not being in airplane mode caused some communication that stole some cpu cycles from the app causing it to lag. I have not exported a ton of videos, but I have not noticed any chunkiness in the exports.

@aryork yes that is exactly the issue... it's smooth in app but having the app export the video to my iPhone photo gallery it is chunky. Anyhow i did the workaround above of recording to my Mac via iPhone cable and Quicktime and it works fine that way..so at least I have a workflow. Overall I'm impressed with this app. Lots of cool data, easy to use. Can easily bring in external video footage and overlay that etc etc... pretty cool. I just hope when I go to Thunderhill next month it actually records everything...

It actually crashes the program.

I noticed that it does this on the iPhone X. I Airdropped the file to my work phone which is an iPhone 7 Plus running iOS 10 and it was able to do the video export... BUT, the issue is, the speed is displayed in Metric and I can't change it to Imperial.
