If clicking "Resync" as shown below doesn't solve the issue, please continue reading
There are 2 possible reasons for Sync error.
1. The video couldn't be re-encoded (transcoded) to one of the formats needed in order to play it on the web or mobile.
It usually can happen with .mov file. Having it edited in editor software can increase the chance for sync error.
To solve the problem, please export your video in .mp4 format and upload it again to your Cincopa gallery
2. If you are using desktop agent , sync error can be caused by agent being down or by unsupported video format.
The solution is to upload your video directly to Cincopa gallery
