Unless you're using the mp4 output setting of Jing Pro to create your Screencast.com content, you won't be able to send the files to YouTube.
The technical reason is that Jing creates it's videos and wraps them in a SWF player. YouTube does not know how to extract the video it needs from a SWF file.
If this is something you're interested in doing, we have another product called Snagit which will record video and send it directly to YouTube. It also has a boatload of other functionality. It is not free, but we do have a 30 day free trial which is not limited in any way.
Camtasia Studio would also meet your needs and is more geared around screen recording and video production. It also has a free trial period. http://www.techsmith.com/camtasia.html
I hope this helps,
What version of snagit do you need to create a youtube supported "video"? I have same question as Nat and I have Snagit (v10). I recorded a couple of videos via Jing and placed them on screencast but would like them to get to youtube too.
So is the suggestion that I use Snagit to capture the screen movements? How do I add voice over? Does Snagit support this too?
Snagit 11 has the video features you're asking about. It will also record audio, but only audio that occurs during the recording; you can't lay down a separate audio track afterward.
Here's a link to a two minute video that shows the how video recording works in Snagit 11:
Be aware, Snagit's recording features are more geared toward quick videos, so there's no ability to edit videos you record. If you need the ability to edit, add effects and more advanced video features you'd want to use Camtasia Studio.
I'd say download the Snagit 11 trial and put it through its paces (the trial is fully-featured). If you like it, you'd qualify for upgrade pricing because you have Snagit 10.
Let me know how it goes.
