The size limit to send a file through email is 20MB. Not to worry however, you may send us the video through a Google Drive link, allowing anyone with that link to have access to its contents. If you are still having issues with your video sharing settings, then I recommend using WeTransfer.
If you have any other issue regarding this process, you can reach out to email@example.com. The Trust & Safety team is better equipped to answer these types of questions for you.
