#codec issues

I can never forget the time when half asleep I saw a flickering fluro light tube and said “must be a codec issue”

So, I figured I'd put this here. Currently everyone working on our short film is hustlin' to make it work for our premiere, but we ran into an issue. While burning the Blu-ray, the film kind of quit working on us. It stops. I'll post what has been written about it between us currently. If anyone can hand out advice, that'd be cool.

So I'm in the audio labs with _________ and trying to burn the Blu Ray. Every single file works and imported to the burner fine, except the actual film. We checked the info on the film file compared to the other files and they're all identical except that the film file carries time code, but I dont know if that even effects it. In the burner it works only as an audio file, and when we tried to open the file on the lab computer, and ___'s laptop, it opened and worked in VLC, which is great, cuz now we know it works and is there, but every other program, handbreak, quicktime, final cut, all read it only as either missing audio, missing video, or both. We're currently trying to export is out of VLC and see if that somehow relink them but I've never seen a finalized .mov file that doesn't carry audio and video together in every place. (it didn't.) 2 questions. 1, has anyone EVER seen something like this and what can we do to fix it, and 2, if this doesn't work, the only thing I can think is to re-export from the original final cut timeline and try again. Of course that means tomorrow is almost a no go. Lemme know.
