This should rather have gone into the mailling list than a bug report as it is
a question.
What you want to use is:
ges-launch-1.0 +test-clip smpte s=0 d=2 set-alpha 0.5 +test-clip blink s=0
d=2 +effect videocrop set-top 10
Arguably your line should work but our parser is not smart enough and this
command his how we imagine the feature.
> Also the "d" property seems to be a duplicate and the "e" property seems broken too.
What do you mean by that, the doc states:
* d=, bin-description The description of the effect bin with a
gst-launch-style pipeline description.
* e=, element-name The name of the element to apply the effect on.
So, `e=` is used to specify on what element (GESTimelineElement ie. clip most
probably) the and `d=` is the bin description.
