As an Odysee user, I got little to no interaction there. Yes, you require it's crypto valute to upload videos tho I am still unsure how this thing actually works.
Considering video uploading, it takes time and sometimes it does not work for whatever reason. This might be when I downloaded my video from youtube and tried to upload it to Odysee, but apparently URL upload is possible... untile Odysee recently released their notice that Youtube started to block that feature, so you need to upload videos on Odysee manualy.
Thumbnail uploading is practical since you can chose it straight from the video... but after uploading the said video, if you want to edit the thumbnail you'll need to put it manualy- and by manualy I mean by browsing trough files on your system trough Odysee, if you know what I mean.
There is no Shorts support.
Posts can be made but those are stashed alongside uploaded videos so... there's that. I don't know if they have the Poll option.
I only made Odysee since it was the only "Youtube alternative TM" that seemed promising, but judging my my own experience, if you don't already have an audience on a large scale, chances are you ain't get any recognition in there.
Odysee speaks about itself as a "wild west", but to this day I have no idea how to get any... correspondance with anyone. Also, I am unsure if that's changed, but commenting requires payment in their crypto too. Again, I am unsure how any of that works and while trying to study it in order to get a proper idea of it, Odysee team claimed that 'you don't need to understand how their crypto valute works in order to use Odysee', at least that's what they claimed at that time...
I will try to check and understand it's interface again in order to say more since right now I barely use it.
In their latest news they got rid of the ads and, according to them, exposed a large crypto scam. For now that's all I have.
