Video editor accidentally catches "white dots flying" - near beaumont

• When: February 27, 2013
• Where: Silsbee (near Beaumont)
• What: Two white orbs, slowly moving through sky, distance between them not changing

3/8 Update: You've chimed in, and the best guess so far is it's a pair of birds. Can't be sure, but birds would probably be flying with a pretty consistent distance between them, so that makes sense!

We've got a pretty neat "accidental" sighting to share today. A video editor was going through some footage and noticed something peculiar. Just 10 seconds after a normal, "identified" plane flies by, "two white dots" show up and move slowly through the sky (about as quickly as the plane). The orbs maintain the same distance between each other the entire time, and aren't going especially fast. Those qualities make me wonder if it's something that could be easily explained - but at the same time, it also has baffled me. What sort of craft could this be?? If you use the plane as a reference, this object is either gigantic or really close (which wouldn't make sense either). Ideas?

Here's the video - look out for the white dots at the 15 second mark!

Here's the video description:

I was editing a video shot for Lamar Institute of Technology up in Silsbee, TX and thought, oh cool, I got an airplane flying through my shot. Ten seconds later I see these two white dots fly across the other side of the screen. No idea what those are.
This was shot Wednesday afternoon February 27 2013. This clip is unedited.
