Ask HN: Where is the industry to get large amounts of video data annotated?

[rdabane]

I'm looking for outsourcing firms to get hours of video data annotated .. on the topic, are there any good open source tools for video annotations ?

Have a look at https://www.scaleapi.com/ and https://www.crowdflower.com/use-cases/

Thanks. Would you happen to know where these firms source the human labor from?

Amazon Mechanical Turk (https://www.mturk.com/mturk/welcome) is pretty transparent on their homepage how you can earn money. Amazon also lets you decide how much money per task you're willing to spend.

https://gengo.com/ for example has a subpage linked in the footer to attract translators https://gengo.com/translators/

The others, especially with a premium appearance, keep that more separate. I assume they created separate brands or use subcontractors and run "easy money, work from home" classifieds ads in english speaking countries to get people in.
