The documentation indicates it uses nearest neighbor, bilinear, 4-tap,
or Lanczos:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-videoscale.html#GstVideoScaleMethod

The code can be seen here:

Resizing and encoding aren't related, except that both might reduce file size.
