create a thumbnail for my video, is it possible?

[florencep7267147]

hello

for videos, I understood that adobe stock generates its own thumbnail,
 mine are often black at the beginning, (they are motion graphics on a black background) 
and even if the mouse hover (a customer visit) probably triggers the animated video preview, 
is there a way to create a preview thumbnail ourselves or to modify it?, if so, where? and how? thank you.

It is not possible. Adobe selects a frame out of your video. I do not know if it is random or not.

No, that is a long-standing request from the community, but it is still not possible. You could try if setting a first image will change something here and does not augment the refusal rate. The cover picture is chosen from the first 5 seconds of the video.

From the Adobe helpx pages:

Preview images

Do: Be aware that your video's preview image will be automatically selected from a frame 5 seconds into the video.

Add a still image to the first 5 seconds of your video clip.

thanks, I understand, I'll see if I can put a still image at the fifth second, but often it corresponded to the end of my vfx, or to a black transition between two vfx if I make a pack, I could maybe just lengthen the effect by one second, I'll try that too, . second question, is the preview of the video when we create the keywords to submit it the final preview? would that allow us to know if it's good or not?

[Abambo]

Well, if it's not working with the last image, it could work with the first one.

Making the first 5 seconds a single still image would eventually earn you a refusal.

[florencep7267147]

yes, ok, do you know if 

 the preview of the video when we create the keywords to submit , is the final preview? 

[Abambo]

You should know, as you submit video. I did submit exactly one video 6 years ago for testing. I'm not into videoshooting.

[florencep7267147]

you know, my images all look a bit similar, imagine an animated line.
 that's not a very helpful answer 🙂
 well, i'll figure it out and take a screenshot of my preview upon submission,
 and compare it to the final preview. 
have a great week and sorry for taking up your time

You're welcome.
