The first sample is a small clip of Sita Sings the Blues, a public domain work. The clip is served from this host, but the whole feature length animation is available at Archive.org. There are several formats available, including a prepared DVD Video filesystem ready to burn on a single layer blank.
The clip here was encoded at a low bitrate to reduce data transfer, and some compression artifacts are visible. Be assured that those artifacts are not present in the original available at Archive.org. Video to be displayed with SWFPut doesn’t need to be hosted on the same machine as the WordPress site. You can use an off-site URL (provided, of course, that it is your privilege to link to the material).
The second sample is a short stop-animation film served from Archive.org. The animation is done very well, and the film is amusing. And cute too. Watch the detail.
