To set up thumbnail seeking in Bitmovin Player

I’m using Bitmovin player. In order to show the thumbnail image on seek-bar, I’ve to generate VTT(Video Text Tracks) file from .mp4. Do we’ve documentation to generate it through the Nodejs client?
Thanks in advance.

Hi! Thanks for your question. How are you encoding your mp4 file? Our encoder can generate thumbnails as part of the encoding process. Depending on whether you’re using it, the instructions may be different.
