Please be aware that studios often do not deliver production ready files, and the files may contain bars, tones, timecode or information slates. It is the responsibility of the partner to ensure that the contents of the submitted file are intended to be played out to end users. Magine doesn't modify the file´s content.

If you are insecure if your content material matches the below mentioned requirements you can use the Open Source VLC player to check e.g. the frame rate, resolution and track information.
