What I find surprising, but probably @MatHayward can shed some light on this matter, is why, 8 years on, Adobe Stock is still unable to provide a feature that every other stock footage agency has, namely the possibility of choosing a video thumbnail, with some of them even offering you the option to seek to the exact frame you want by using the video playhead.
I take it that the recent introduction of the video subscriptions is a direct response to dwindling (or disappointing) video sales on the platform. Yet, instead of focusing on why some videos don't sell (perhaps because the customer sees a black frame or a blur as a thumbnail, instead of the actual subject matter of the video), the preferred approach seems to be dumping video prices and "hoping for the best".
This coming from a primarily tech company is intriguing (shoemaker's son always goes barefoot?)
All the video agencies I work with repeatedly hammer on the importance of picking the right frame to drive sales, for the obvious reason customers won't have time to play or even hover on hundreds of videos to choose the one they like.
The fact that Adobe doesn't understand this is THE one priority item that would boost video sales is beyond me.
Sad, but true.
