Even if a file has a compatible container format like mp3, mp4, or mov, it could still contain incompatible data (codec) that InqScribe's media player cannot parse. Converting, or transcoding, will rewrite the audio and/or video data into a new file that will hopefully be more compatible with InqScribe.
Note that InqScribe cannot convert the file for you, so you will have to use a third party conversion tool. There are free, open source options available, such as Audacity and Handbrake. Head over to our InqScribe blog below for a step-by-step guide to converting media files.
