Your Casio is recording using MotionJPEG video compression in that AVI wrapper. MotionJPEG has a history of this type of problem. It is debatable whether the issue is the absence of the codec or the availability of the codec to the program. Nonetheless, the possible solutions include:
1. Checking the Casio for a utility that may have come with it which would supply the codec
2. Download and install the Morgan MotionJPEG codec (it is not free, but it comes as a tryout...if it works for you, you can decide whether or not it is worth the investment)
3. Convert the MotionJPEG.avi to another format that is compatable with Premiere Elements 12. What is the computer operating system on which 12 is running?
Please review, consider, and then let us know the outcome.
Add On...With all suggested downloads, check out the site information and the installation details carefully to avoid unwanted inclusions on your computer.
Do you have QuickTime installed? That has been proven necessary for MJPG.
Thanks to your advice I solved the problem.
I installed the codec Morgan M-JPG from an existing link (http://morgan-multimedia-mjpeg-codec.en.lo4d.com/download) different from what I have proposed, this link was continually blocked by my anti-virus.
After restarting Prenmiere Elements 12 (without reboot) AVI movies of my Casio have been read.
The operating system of my PC is Windows 7.
In fact I have not installed QuikTime, due to other ploblemi on my PC due (in my opinion) to such software.
QuickTime is a requirement for Premiere Elements (any version).
And you do want to be running Premiere Elements and QuickTime as Run As Administrator or from a User Account with Administrative Privileges.
Without the QuickTime install, you will not get the Premiere Elements share QuickTime choices and presets, and the absence of QuickTime on the same computer as Premiere Elements will results in other expected and unexpected mishaps.
Even if you have Windows 7 64 bit, this should be an appropriate download for you. Please check it out.
What computer problems have you believed were caused by QuickTime?
Very pleased that your MotionJPEG.avi import issue is resolved. Good job.
