We're planning to make a good video howto section for our services but we have no idea what software to use?
Are there any free softwares around? A software that can be used to record only part of the screen action would be good in this case. The software must allow also adding comments to the videos(i.e "click here" etc).
I like Debugmode's Wink (I've not got enough posts to provide a link - but a Google search for "debugmode wink" will provide the results) myself - free of charge, record only set windows/screen areas, add comments etc.
Worth every penny and actually fairly 'cheap' for its capabilities and ease of use if you create demos constantly for clients. If you just want some random ones for your hosting service though, I agree with the above poster.
Demo Builder is missing some features that would be desirable (mainly for editing multiple files at once) but other than that it has worked great for us.
So I don't know about the other software, but I can attest to the fact that demo builder works great for creating tutorials, and it isn't that expensive.
Though if you are just looking for run of the mill tutorials you may want to look at a hosting tutorial provider because they would be cheaper (most likely) and would take the time out of creating the tutorials. However, being a web host myself it is very nice having tutorial software to create tutorials for specific things to our service.
