[Feature]: Video NFT previews

[CedarMist]

Is there an existing issue for this?

• [X] I have searched the existing issues

SUMMARY

Viewing NFT images on Oasis Explorer is amazing, but it only supports images. Videos (e.g. mp4 files) are becoming used more frequently but no preview is shown

DESCRIPTION

If we look at this example NFT:

• https://explorer.oasis.io/mainnet/sapphire/token/oasis1qqn6h6mavvcc38z82q330drf3jjlx2zmlyzukqj9/instance/0

It shows 'No preview available'.

This is because the frontend will only show previews for images, this is implemented at:
