I want this video but don't need a recurring subscription.
If you only need one video, you can subscribe to any Unlimited plan and cancel right after.
You will be able to use the benefits of your subscription for the next 30 days and the completed videos will remain available for download from the My Videos page. The commercial license for the videos will also apply in perpetuity.
However, if you wish to make changes to any of your videos after your subscription expires, you will need to subscribe again in order to produce the new video at high resolution and download it without a watermark.
