No, not particularly.

If you want to display just this image, use the 'freeze' element, which
we use for debugging image-related issues; it will continuously repeat
the first frame (which is exactly what you want). To merge an image over
a video, use the 'videomixer' or 'imagemixer' element, both handle still
images correctly (i.e. merge them over video 'forever').

Cheers,
Ronald
