I think the Closed Captions are absolutely great.
It helps me attract a way bigger audience, since people from all over
the world can now understand my videos, even if they can't understand
English.

However, making the captions is quite frustrating.
I agree with Whizz4u. You should be able to write them online while
logged into YouTube.

I use the programme recommended by YouTube: Subtitle Workshop.
It's free and easy to use. However, the captions made in that
programme appear different on YouTube than they do on the programme
itself.

For instance, I get nice clear 2 lines of text on Subtitle Workshop,
but 3 or sometimes even 4 lines on YouTube. And some lines only
contain 1 word!
It's very frustrating to keep fixing this, re-uploading the subtitles,
checking them again, editing them again, re-uploading, checking ect.
ect. It's very time-consuming.
Especially when you plan om making subtitles in multiple languages.
(for instance, I make them in German, Dutch, French, English and
Norwegian)
I don't want my closed captions to be 3 or 4 lines, because it makes
the text it's acting as a subtitle for harder to read, sometimes it
has them overlap. And I don't want to change my videos.

I guess I have to keep doing it this way but it would be great if
you'd try out Whizz4u's idea.
That would sure make things a lot easier.
