Mailchimp just launched some extra customization options for their automated video conversion.
That certainly saves times compared to getting a snapshot of the video (which at least I can get with pixel precision with Ashampoo Snap, so I don't have to actually edit it), uploading and using the image for the link.
It also supports converting videos out of RSS feeds – which is conceptually useful for me because both this blog and my personal blog are automatically e-mailed through their RSS feeds, without me doing anything.
I have also just changed the feed to this new server.
