Thanks for your replies. Now I need to find best workflow to move 2500 files to 4 agencies. Maybe someone can share his workflow?

Interesting thoughts. Thanks, it's look like it's time to cancel exclusivity.

Hi!
Don't want to start new topic about the same thing.
Now my video port is exclusive at iStock and Getty. I start 2017 with only 300 footages and now I had online about 2500 clips, but my income is not so good as I expected. June was my best month with $650 and august was my worst month with only $28, September and November $300 and $500. I don't want to quit my exclusivity, but my wife want to upload to another agencies. In 2018 we can produce about 4000 video clips, so I can upload 2000 as exclusive at iStock and 2000 my wife can upload  to SS, P5 and VB. My question is - is there any sense to work this way? Please share your thoughts.
