Building video sitemaps requires extra crawler configuration. However, beyond that,
making video XML Sitemaps for search engines such as Google is similar to the process for
generating normal XML sitemaps
Note: Depending on the website, it may not always be possible to generate video sitemaps.
For video sitemaps, you will first have make sure configuration includes relevant video
file extensions
and
MIME types in
output filters.
The list of video formats Google accepts include:
mpg,
mpeg,
mp4,
mov,
mv,
asf,
avi,
ra,
ram,
rm,
flv
and more as they are added.
To make things easy,
A1 Sitemap Generator contains a
preset option that configures all settings to work for most video websites.

Note: Even when using the
preset
button, you can still benefit from configuring the video sitemap crawler options.
Using
output filters
will help when multiple page URLs contain the same video file.
After website scan, you can create the Google video XML sitemap by choosing the correct sitemap file kind to create:

While
.swt flash movie files are not officially supported
if trusting the documentation provided by Google for video sitemaps, you can still include such files
as videos. To do that, add the
.swt file extension to
output filters.
