Video previews for open edition?

I plan to mint a video as an open edition using a CSV for an existing collection to claim.

  • will the preview be a short clip or the entire video?
    Also, if I use the max limit for video, will it still be compatible with platforms like Foundation and Opensea?
    Thank you!

preview is probabably an image file. something like a gif or jpeg. you can always give it a shot and edit it if it doesn’t look the way you want
