I’ve been experimenting with different options for uploading video to Tumblr. The service’s built-in video player with play Flash on the desktop, and H.264 for iOS devices, but it will not play H.264 for those of you who don’t have Flash installed on your Mac.
Vimeo Plus looked like a great option, but it doesn’t play nice with Tumblr.
Moving forward, I’ll be posting videos for Tap to Focus to YouTube, then embedding them within Tumblr’s dashboard. That way, they will play in Flash, or in H.264 for iOS devices.
If you run a Mac without Flash installed, I highly recommend the YouTube5 plugin for Safari.
