I recommend Figshare which supports sharing scientific data in various formats (images, videos, structured data, code, etc). You have the option to share with ouror without creating a DOI. However, beware that in the context of blind peer-review this might allow authors to identify you.
Zenodo is also a good option, but in this case associating a DOI is not optional.
Alternatively, you could just send the video to the editor to share with the authors.
