U.S. government works are
free of copyright (public domain). This includes all videos and films produced by federal employees as part of their official duty. However, limitations may still apply, if copyrighted material appears in a video.
Based on an extensive review of government video libraries, I recommend the following 11 collections. The video libraries are broken into four categories followed by six tips to improve government videos:

Top News Video Libraries

Very up-to-date military news in a television newscast format streamed online by the Department of Defense. The site includes several "channels" for top news, interviews, front line stories, and more. The production quality, timeliness, and anchorwoman are professional grade. On the downside: some videos do not have dates, and the "play" and "playlist" buttons are visually associated with the wrong videos.
Production Quality:
Excellent!
Update Frequency:
Several videos added daily
Accessible?:
No—neither captioning nor transcripts

Top Educational Video Libraries

Well-produced and informative videos on current scientific issues. NSF recently started offering their videos in Flash format, which has increased the speed and reliability of their new releases. The only downside to these must-see videos is that only one new video is released per month.

About 100 total. One new release monthly

The best NASA videos are their excellent short documentaries to explain most of their current missions. It can be a bit tedious to navigate to the videos through each "mission", but it beats hoping your mission is one of the lucky few that is
featured or sifting through hundreds of videos in the
archives.
Many missions make their videos relatively easy to spot, but for
Hubble videos, click into the
Hubble mission, then click "multimedia" on the left side of the screen. Closed captioning is available.
Production Quality:
Excellent!
Quantity:
A couple hundred

Yes—captioning provided

The Library of Congress has an extensive collection of distinguished speakers and scholars on subjects of History, Culture, Religion, Science, and more. The videos are generally in "talking head" format, but the content is educational and sometimes related to current events. You must navigate the videos by category. It would be nice to see which videos were added most recently.

Nice videos provide virtual tours of the White House. Many of the tours are "led" by high-ranking officials, including George W. Bush. Sometimes the server can be slow.

Through this large collection, viewers can learn about many careers. Each video explains and portrays a given career including what the work is like, what training is needed, and more. The most in-demand careers are promoted at the top of the collection.
This is excellent content that can help anyone choose a career. But the production quality and download speeds leave much to be desired.
Production Quality:
Poor — Fair
Quantity:
A couple hundred
Accessible?:
Yes—captioning provided

Tips for Government Videographers
The best government video collections are polished and professional. These are some rules of thumb observed by the best video collections:
- Be sure your videos work and load quickly. The most robust government video sites offer videos in multiple formats or in Flash.
- Make sure your videos have some narration, dialogue, or explanation. Silent movies, whether paired with orchestral accompaniment or not, are no longer innovative.
- Provide videos in high or relatively-high resolution.
- Do not provide too little content per video or per video library. A year-old video library that contains 3 or 4 videos is not impressive.
- Include the content date if possible.
- Make your videos 508 accessible with closed captioning or text transcripts.
- If you publish videos only a few times per year, do not call them "news". Call them "video press releases" instead.
