Exporting OMF - "Unable to Open A Required File"

[wtm5012]

Hey all - I'm trying to export an OMF for another mixer, and when I try to export the program gets to "generating audio files" and gives me an error that says "Unable to open a required file". In the bin, my sesx file has the red exclamation next to it. I've tried everything I can think of to fix it. Anyone know a fix or have any ideas for me to try?

If you are going to embed the audio, the total file size can't go over 2GB, and sometimes on big projects that's not much of a limit. If that's likely to happen, then the thing to do is to use the separate audio option. Yeah, not quite as neat but could get you out of trouble. But as a check, that may well be worth trying anyway if you aren't already doing it. Other things to consider are where the file you are trying to include is stored. If the OMF generator requires immediate access to a file and it's stored remotely and not available at the absolute instant it's required, then this is the sort of message you're likely to get. The answer to that is simple; make sure that all the files you want to include are stored on a local drive, and if it started out as a compressed format, that the copy that was decoded is the one that's available for the OMF - I'm pretty sure that the files have to be in the working format before you can include them.

I can't think of anything else obvious, though.

I'm having the same issue as the OP. I've tried reducing the size (it's nowhere near 2GB), ensuring all tracks are aif or wav, and making sure they're all stored on a local disk, but I'm still getting that error message. I'm trying to find a way to get my session to a usable format for my mixer, who works in Pro Tools, and I'm at the end of my abilities/rope with this issue.

Hopefully the OMF specialist here (SuiteSpot) will spot this - he's definitely the best person to advise on these sorts of difficulties...

Thanks SteveG

"it's nowhere near 2GB" 

When you say that you need to be sure that the total of all files that are referenced in the session don't total 2gb.

You MAY also find that if a file has several clips the entire file may be embedded more than once.

If you are really stuck send me the session (ie sesx and media) and I will convert it to a PTX for you for use in ProTools

You have a number of tracks which contain a mix of both mono & stereo on the same track.  Convert the stereo clips to mono.  The OMF will be in mono so these stereo clips mixed with mono clips on the same track will result in additional tracks, clips and size which may be enough to take you over the 2gb limit

Oh my goodness, you're right. I'm so silly. Thanks very much!

Hello

I'm having the same issue as OP. 

Could you please elaborate on " use he seperate audio option".

I'm afraid I don't understand.

The WAV. file I edited is 2,05 GB and has 4 audio tracks + a WAV. file of 1, 91 MB with 1 track.

Thanks!

OMF has 2gb limit and even having your total media size under 2gb doesn't mean it will still be under 2gb

You could try

1. exporting a 'reference' OMF (where the media is seperate from the OMF) rather than an encapulated/embedded OMF

2. AATranslator and just convert from sesx to whatever format you want (eg PTX for ProTools rather than a useless OMF)

Hello

thank you for responding so fast!

The exporting as reference OMF worked, It was going to take 18 hours "generating audiofiles for OMF" then got a "traject directory not writable" but it exported anyway!

Thank you so much!
