OK, so, Kdenlive is using about 33% of the time, and thumbnail
retrieval would only be a portion of that - I estimate less than 20%
of the overall time. In MLT, I could make an alias for the avformat
producer, for example "avformat-validate", that will be the new
default. Then, have it serialize itself to xml as simply "avformat."
Next, when it sees it has been loaded through "avformat" instead of
"avformat-validate" it will skip the validation and expect the
properties it needs to be deserialized. I do not expect it to be too
much work, but it will have to wait until just after the next release.
