avoid blackbox since you have to pay a commission to them to upload your file to all the agencies...you can save money and do it by yourself...

And then pay 22% of your royalties FOREVER for every clip you submitted through them.  And get nothing at all in return.

OR... pay $5/month to submit up to 250 media per month to 30 agencies (a small increase in fee if you really want more than 250/mo) through StockSubmitter.  No loss in future royalty.  Better submission tools. Thousands of percent (yeah, possible) cheaper.

FWIW, I have no relation to either other than (1) I submitted 800 clips to BlackBox and get tiny sales, and (2) I submitted 900 clips - and counting - through StockSubmitter and make roughly 7X the total revenue that I get from BB (even though BB had the jump with the first clips going there).

Note that if you join BB and their Facebook forum, you will find nothing but Good Things said there. That is not because only good things happen, but rather because the owner of the group will immediately delete ANY post that is not rah-rah-ain't-we-great.  Ask the slightest question and you either get a canned "RTFM" or you will be deleted. There is very little in between.
