html - Can I have a video with transparent background using HTML5 video tag?

Question

We filmed a spokesperson on a green screen and have the video files ready in multiple formats.

With Flash we could use the wmode transparent within the param and embed tags, but is there something similar to this with the video and source tags in HTML5? Is it even possible to properly save .m4v or .ogv videos so that we can play these files with transparent backgrounds on our browsers?

Thanks

Yes, this sort of thing is possible without Flash:

However, only very modern browsers supports HTML5 videos, and this should be your consideration when deploying in HTML 5, and you should provide a fallback (probably Flash or just omit the transparency).
