    I'm working at a film festival where we receive a lot of mp4/H264 files with 5.1 sound.

    The files will be screened in cinemas with Dolby Digital Cinema Sound Processors, but also in other locations with only stereo systems. Also the playback system will be different in each location, some will have PCs, some Laptops.

    We are verifying every file before the festival so it doesn't have any drop frames, stuttering or audio errors.

    The problem is : can I verify on my home system (laptop with no sound card, VLC player, stereo system ) the video files with 5.1 and then play them in the locations without something going wrong then? Or should i keep converting the 5.1 into Stereo, as we did last editions and everything worked fine.

    Do you have any computing device that has a digital output? You can feed that into your receiver and see if it locks on to a Dolby Digital signal. VLC will say if the file has a multichannel stream. However you will not be able to actually verify it works without decoding and listening.

    I think your playback system is going to make some of your decisions for you.

    If the "stereo" systems are receivers capable of decoding Dolby Digital, but only configured for 2 channel then you should be fine with Dolby Digital as the receiver will down mix. But if they are traditional stereo devices that only understand left and right then you will have to do that ahead of time.

    I decided to keep it simple and downconvert to Stereo through Premiere the remux the video-audio.
    I'm just afraid some distortions/channels too low might appear in 5.1 cinema theatre. (errors I couldn't spot on my home stereo system)
