Seems to be a codec problem

I'm trying to edit some video sourced from my Canon Legria HF R66 movie camera. I had nor problem editing MP4 files from this camera with previous version of Magix. I think it has worked with the current version, but not sure.

The symptom is sound works, video us a plain green screen.

Based on other posts in this forum, it sounds like codec problem.

MediaInfo analysis is:

Codec ID : mp4a-40-2

My questions, if this makes sense, are Where can i download a codec from and how do I install it in Magix.

Thanks.

Jim

@james-o7579

First, exactly which Magix program, version and edition do you own? And have you registered and activated it? And, if you have, did you also download and install all the additional content that is available for your version? The reason for asking these questions is the answers will help us to help you! Unless the file has a very unusual codec involved it would be very unusual for a fully-activated version of any Magix program to fail to display an .mp4 file

We also really need the FULL MediaInfo analysis (show us the Text view) to be able to assist further.
