Hi. In answer to your second question, yes.
Saying “how exactly”, I’ll no doubt be telling you things you already know, but here goes. First of all, this only seems to work on a PC. I’ve found no way of copying the transcript on Android, for example.
I open the video, click on more in the description below and scroll down to show transcript, and click on that. This then opens at the top right. I make sure it’s showing Dutch, and not Dutch (auto-generated), then click on the three vertical dots above the transcript. This allows me to toggle the time settings off.
I then copy the transcript, without the time settings, and upload it to Readlang, go back to YouTube, click on Share below the video, and click on Copy.
I now open the text on Readlang, open the YouTube page on the right, and paste in the link. I then go back to YouTube, toggle the time settings back on again, copy the transcript with its time settings, open the YouTube page on Readlang again, and paste it in, and Readlang does the rest.
This might all sound a bit fiddly, but I do it so often that it’s like second nature, and really only takes seconds.
Incidentally, when I want a reasonably good transcript , and YouTube only has auto-generated, or when there is none at all, I use TurboScribe (free version - up to 3, maximum 30 minutes each, per day).
I also sometimes record the audio with Audacity, and upload it to Readlang as an MP3, which Readlang then converts into text. This is a bit more fiddly, as I then need to copy Readlang’s generated text to a new Readlang upload, in order to enable the video, and then delete the first, audio, version. But again it only takes seconds. And would be an easy way of generating better, usable texts from Jeugdjournaal.
