Video Tutorial / Screencasting
Posted: Wed Dec 09, 2015 12:02 pm
Does anyone have a suggestion on how to make good screen castings or video tutorials?
I once saw a KICAD tutorial where the fellow used text to speech for the audio. I liked this as it should have allowed google translate to be used such that the text could be translated to different languages, then the text to speech would allow you to make the same video in multiple languages. I see espeak allows text to speech for multiple languages, but I don't know how to get these synced with the video. I'm kind of thinking of a script or some kind of program that takes a list of events, say in one text file called events.txt, with time stamps for each event one per line. Then the text to be converted in a different text file, again one utterances per line, which matches the event times. Then the script starts recording an audio file, and at each event, it plays the text file. The audio and video can be merged with a tool like nandub. However I don't know how to get that single audio file. Once you have the first video working, then you can copy the text to be spoken into google translate and re-run the script, making an audio file in a different language.
An alternative, which would be something like openshot, then add and remove audio tracks. You would need to create a pile of audio files, then manually put them into the video tracks. Then when you try a different language, you get to do it all again. Which is a way to get there, but a bit labor intensive especially if you try multiple languages.
Of course for windows some tools worth considering include, camstudio found here https://sourceforge.net/projects/camstudio/ (beware the other programs that claim to be camstudio) also see it's lossless codec found here https://sourceforge.net/projects/camstudio/files/legacy/, as well as nandub, audacity,
