Your questions answered
I don't see the embed tab shown in this video. What gives?
Embed code is normally only available for video in a public collection. You can also make private content embeddable if you specify a domain on which it will be public. Contact dartfish.tv support to do this as described in the above video.
Can I change the size of the embedded player to better fit my website?
Yes. There are a number of parameters in the embed code that you can adjust to suit you needs.
