downloadtedvideo
I was able to download videos from TED simply by clicking on download button since couple days ago.
But suddenly it has been hidden now! [it was on the right hand]
So, How can I bring it back?
or there is another way to download these videos? [I tried ted downloader and Amara but I couldn't as well].
TED videos can be downloaded directly from their website:
You can also get it through their RSS feed if you want.
Because the premiss of the site is that you go back to view your favourite videos so you can see (more) advertising, sponsored links etc.
If you download the videos you could watch them as many times as you wanted without seeing all this.
There's also the small matter of copyright - you only have the right to view the videos, not copy and (potentially) redistribute it.
Best Answer
Since you already know the name of the video you want to download, you can go to the Ted Talks List and download it from there.
You can also use the Ted Talks Downloader to download multiple videos at once.
