I started looking at using webpagetest API for scripted testing but was wondering if it’s possible to get the comparison filmstrip image from the API ?
so
https://www.webpagetest.org/video/compare.php?tests=TESTID1,TESTID2
the resulting filmstrip that is produced ?
The compare.php page doesn’t generate a single image, each frame displayed is a separate image. There is a link on the page to get a filmstrip image though (just below the filmstrip). If you replace compare.php with filmstrip.php you should get a png of the comparison filmstrip (warning, it may be HUGE).
thanks Patrick for tip on filmstrip.php
