Hi Pragi:
I may have misunderstood your question. If you're looking for video clips for personal videos read on.
I've been on videoblocks.com for two years or so. Yes, they do have a lot of bad reviews and I was reluctant to join.
But since most of the places selling video clips are $80 (and up) for a 10 second clip, I joined anyway.
The first year I really got my money's worth. I downloaded some nice 4K content that would have cost a fortune anyplace else. For $100 yearly it was a bargain.
They seem to have a new policy now. For the same yearly price there's still unlimited downloads but it's limited to certain clips. The clips I really want at this point cost extra. So the deal is not as good as it used to be.
For a decent selection of HD quality video clips at a reasonable cost I haven't found a better place.
