[Athen] Cielo24

The biggest use I've countered so far is the captioning of 7000 videos on <http://classx.stanford.edu/>, which are short, independent video segments culled from engineering lectures. Engineering jargons and maths abound, as you can see from the thumbnails.

Even at 99% accuracy, Engineering still need their own SMEs to check the content and correct erroneous engineering terms. They provide a backend UI's to make your own corrections. I believe the reason for the lower 99% on specialised topics is because Cielo24 cuts up its video and crowd-source the segments, thus retaining very little context for their transcriptionists to do a good job.

Cielo24 is responsive to requests. When they encounter difficult audio, the client will be contacted about the delay.

Cielo24 has very speedy email responses, but no one answers the phone, and so it takes a long time to get a complicated issue resolved.

So, my recommendation:
1. Use Cielo24 for non-urgent videos.
2. Arrange for your own SME verification.
3. Don't give them anything you can't explain over email.
