|Target Version||3.X||Fixed in Version|
|Summary||0002652: AAF / OMF support|
|Description||AAF / OMF support in Ardour can't be at the moment developped because of a lack of sponsorship. |
So I've decided to create this features request in order to help its development.
Why this features is so important ?
Because EDL format like AAF/OMF allow project transfers from a software to another, with the wave track data, plugins and automation parameters saved inside.
Absolutly necessary to mix a project in ardour while tracks were recorded and edited with another DAW (Cubase, Protools, Nuendo), or to transfer the soundtrack of a video project from the video sofware (Avid, FinalCut, Premiere) into Ardour in order to edit and mix it.
Like the vst support question in Ardour was a bit conflictual (vst is a crappy system, it comes from the windows world, etc...) nevertheless AAF/OMF support is an essential condition for professional audio world to be able to switch on an Ardour/Linux based system production.
Ardour is a great system, I just want to make things progress!
There was a person called John E in the forum that was ready to start coding the AAF/OMF features for Ardour if some sponsors could be found.
So we just have to get involved and donate to see this great feature arrive !
|Additional Information||I founded some stuffs in the ardour forum that can be usefull :|
- an open source project to read and write OMF project : http://sourceforge.net/projects/deck2omf [^]
- Symek's EDL2SHK.py script

Hi LCut. Thanks for kickstarting the sponsorship for this issue but I've got some news that might get you up & running pretty soon. Check out my web site which gives some preliminary information about my AAF plugin which is now called ArdourXchange:-
At the time of writing it only supports importing (not exporting) and it's only available for Indamixx - but here's some great news....
If you've never heard of Indamixx it's a complete "studio-in-a-box" aimed at pro and semi-pro musicians. It includes Ardour, along with some other great Linux audio packages which all run under a distro called Transmission 2 (which I believe is a variant of 64studio).
Currently, you can buy Indamixx complete with suitable hardware (i.e. a laptop or handheld device) starting at around $499 - but even better, you'll soon be able to buy the software only (on a USB memory stick) for under $100. In fact, I think it's even less if you don't want the memory stick!! That'll get you a working, ready-to-go studio (including AAF support) for not much more than your sponsorship amount.
I've probably jumped the gun a bit here because the 's/ware only' version is still being tested - but anyway, I hope that's of interest.
Hi John. Thanks for your answer.
It's great that an AAF plugin exists, and the Indamixx system looks like an interesting Linux-based system.
But my aim here is to sponsor an Open Source AAF/OMF patch for Ardour. I'm a semi-professional sound engineer and use Cubase and Protools software, so AAF support is'nt a problem for me. But I believe in open source software, and try my best to support Ardour as a great open source DAW.
Sorry to tell that, but even if Indamixx cost 10 bocks, then it would'nt more interest me. I want to have the choice what hardware and software to use. It's a basic principle of open source world, and I don't want to use Ardour on a propriatary system, even with AAF format support.
I know that there're a lots of work to achieve, and all of that can't be free.
That's why I open this issue.
If there are ways to open your work to the community it would be great !
Well, introducing this feature to the community was the main reason for doing a deal with Indamixx. FWIW I'm treating any income generated by Indamixx as being sponsorship too. Therefore people can sponsor me the conventionsl way (i.e. making a pledge and waiting for others to join in). Or they can sponsor me by buying Indamixx.
From a developer's perspective the Indamixx connection delivers 2 important advantages:- (1) It gives users a choice and at least some kind of solution in the short term. (2) People can be using (and therefore testing) software that would otherwise just be sitting on my personal PC, waiting for enough sponsors to come forward. The end result is that people like you (who are happy to wait for the source code) should hopefully get a more stable product in reward for their patience.
I would recommend using the official SDK and manuals for interacting with AAF files. I know that there is some work to add this support to Blender as well and both using the same libraries would allow flawless transitions from Ardour for audio to Blender for video editing.
I mean why replicate work that has already been done.
Hi openmediaforge - you might have misunderstood the problem with Ardour and AAF. Ardour can already support AAF via a plugin (that I wrote) which does indeed use the AAF SDK. However, that plugin is an adaptation of something totally different that I wrote a long time ago for Windows. Therefore although it works, at present it has 3 drawbacks:-
1) It isn't open source.
2) Anyone who wants it would need to be able to build Ardour themselves.
3) Even when installed, it requires Wine (or Crossover Mac) to run.
The quest for sponsorship is to enable me (or someone else) to provide AAF support as a standard, open source feature within Ardour itself (i.e. not as a separate, closed source plugin). At the current level of sponsorship, around 300-400 sponsors would be needed to make this viable. But at the time of writing (and despite its apparent popularity) this feature has only 3 sponsors. That's what's holding us up at the moment.
IMPORTANT NOTE: If anyone's interested in helping to test my plugin, I've just released a time-limited version, FREE OF CHARGE for early adopters. You can get a copy COMPLETELY FREE as long as you satisfy the following conditions:-
1) You pledge at least $50 to this feature request; AND/OR
2) You already contribute to Ardour in some other way, either financially or technically (developer / translator / tester etc); AND
3) You will not be distributing the plugin for commercial gain
Depending on when you install it, the time-limited copy will work at least until the end of July 2010. Hopefully, that'll be enough time for enough people to come forward and sponsor an open source version. There are a few limitations, described in my preceding post (mostly, you need to be able to build Ardour from source).
If you'd like a free copy, use the 'Contact' link on my web page:-
Hello. I am interested in this being open source, and have pledged $50.
I would like to see OMF support too eventually, as my 'other daw' is Cubase, but first things first eh!
final cut and nuendo provide xml versions of their sessions
this could also be a way to go instead of omf or aaf support
maybe its more easy?
Just to say that a guy wrote some code for .OMF support in reaper daw, and I've thought it could be interesting here, because he decided to release the plugin's source code.

I don't consider this work to satisfy the feature request here, but it will soon. I thought that everyone attached to this bug should be aware of stuff I've just committed (to ardour3 only at this time). This is from my post to the ardour-dev mailing list.
Thanks to Hannes Breul, who developed code for Reaper under a BSD-ish
license, I have just added the ability to import OMF sessions as
Ardour sessions. This needs testing and it also needs further
development. Right now, its not even very easy to run it because of
its use of the uninstalled version of libpbd ...
* it imports ONLY OMF2 files. OMF1 is not supported
* it will not identify audio files that Ardour cannot read (e.g.
embedded MP3 files) but no[ problematic errors result from this
(requirements: sqlite3, sndfile)
LD_LIBRARY_PATH=/path/to/ardour/build/default/lib/pbd ./omftool [ -v
version ] [ -r sample rate ] [ -n session name ] OMF2_session_file
this will create an ardour session whose name will based on the omf
file name OR the -n argument. it will be created in the current
I don't have much time to spend on this myself. The basic stuff is all
there, I've been able to load at least a couple of test OMF sessions
from other DAWs and get audio from them. Someone needs to step up and
make this puppy their own. Bug fixes/integration with waf/usability
fixes/GUI ... its all yours for the taking. I may fix trivial errors,
but I need to get back to other things now that this is basically
Incidentally, this also provides a fairly good guide for how to create
an Ardour session from scratch, should anyone want to do this for
other "session" formats.
On a personal level, there were never enough sponsors to tempt me to get started on this - and now I'm too busy with other projects... :-(
Having said that, wasn't there another developer (last year sometime) who wanted to get involved in OMF development? I can't remember his name just now but I'm sure I remember someone who expressed an interest.
|this is a real newbie question, sorry: how can i sponsor on that issue? i just made an account on tracker, but i dont know how i can actually donate. when i click on sponsor, it shows the sum i d like to sponsor, do i have to sponsor then the same amount through the normal ardour sponsoring paypal thing? thx folks...|
@calimerox: you pledge an amount here and pay only once the issue is resolved (usually by making a donation to the person who fixed it or to ardour.org and Paul will re-distribute, but we'll get to that later).
Then again the chances that ardour will gain OMF/AAF support are slim, see the last comment at https://community.ardour.org/node/8491 [^] but since ardour is free-software, anyone can pick up this issue and claim the bounty.
|is there reference docs for AAF/OMF anywhere? thx, Arno|

I don't think there's anything available for OMF anywhere but AAF is still alive (though I'm not sure if it's being developed any more...) However, its previous owner (the AAF Association) changed its name about 10 years ago and is now known as AMWA (Advanced Media Workflow Association). You can contact them here and ask if they've got any documentation available:-
A word of caution though, if you're thinking about adding AAF support to Ardour... At various times I've offered to do this work myself (for Mixbus). What's stopping it is a conflict between the AAF licensing terms and Ardour's (GPL) license. I've forgotten what the conflict is (maybe someone else can explain better...)
AAF relies on some technology from Microsoft that is licensed in a way that prevents its use in open source projects. There was an attempted reimplementation (it is basically "filesystem in a file" stuff) by the GNU project, but it was never really finished and wasn't fully compatible with the MS stuff that AAF relies upon.
By the way, AAF is the WORST specification I have ever read. It is the epitome of design by committee. The people involved show no signs of understanding at least half of the technology their specification relies on. When I try to imagine a less elegant specification for this purpose, I cannot.
And to repeat what is written already: there has never been any documentation available for OMF. At once time, I made a stab at using the library developed in connection with Reaper, but soon found out that it was incredibly incomplete (there are lots and lots of OMF files it cannot open). This is partially because every implementation of OMF has no specification to adhere to, and so they all differ in incompatible ways.
Hi Paul - I've studied the AAF license quite extensively and I'm still not sure what the problem is. The license does state that AAF contains contributions from different parties but that each contributor grants a worldwide, compensation-free, nonexclusive license to the recipient, subject to certain requirements. AFAICT those requirements are:-
1) That you must not re-brand the AAF code as if it's your own.
2) If you modify the AAF code you must make those modifications available somehow.
3) If you incorporate the AAF code as part of some larger project, the larger project can use a different license as long as it's made clear that the AAF part is governed by its own (separate) license.
You're absolutely right about the design though!! And considering they're supposedly for multimedia use, AAF and OMF have some highly questionable limitations (e.g the fact that they don't support MIDI...)
