Thanks for your question.
If you have made individual videos you will need a third party video editing tool to combine them.
Hi again Suaidah,
There are many video editing tools.
Microsoft Movie maker is a basic one.
You may want to search around to see the best one suited to you.
Camtasia seems to be a popular choice when making video edits.
Sorry that you are having this issue- are you getting an error message when you try and import a video? If you are getting one something like "cannot load file.... It is either an unsupported media type or required codecs are not found", please ensure that you have updated your video codecs, or if this does not resolve the issue try rendering your scribe as a MOV, then use some video conversion software (such as Freemake video converter) to convert it into a WMV and then importing this video file into Camtasia. Alternatively you could try using Windows Movie Maker, or iMovie (if you are on a mac).
If you are making each scribe with only one drawing, you may want to watch the tutorial videos: Videoscribe version 2 tutorials .
You would need to use a Video Editing tool to do that. There are many our there some are free and some cost money and it would depend on your specific needs as to which would work best. A few examples of software that is used fairly widely by other VideoScribers can be found futher up this forum.
