Hello,

I want to pass video projects back and forth between myself (I use kdenlive) and people
who use other NLEs. My most important need is interoperability between kdenlive and
Vegas Pro. I also desire to interoperate with other popular NLEs (this would be Adobe
Premiere Pro, then Final Cut Pro, then Avid, according to some survey
http://www.learningdslrvideo.com/nle-ma ... breakdown/
)

I believe that the way to do this is through AAF (Advanced Authoring Format). We should be
able to convert between AAF files and kdenlive XML files. I can imagine this being included
in kdenlive or taking the form of a standalone program, that does two-way conversion
between kdenlive XMLs and AAFs.

I am ready to offer $1000. However, this is not yet a firm offer, because the problem
to solve is not defined precisely:

- Which effects will be taken into account? The absolute minimum would be to convert
a project that nas multiple tracks with cuts, but the more effects will be correctly converted
between kdenlive and other NLEs, the better (audio volume, various audio corrections with
keyframes, fade to/from black, color correction, alpha blended titles, and more)

- On which NLEs will this be tested? Is the developer going to test it fully, or should I participate?

- How do we convert pathnames to clips? kdenlive runs on LInux, the other NLEs run on Windows
or Mac, so we need to design a conversion scheme.

At this point, I am asking for two things:

- Comments: does this proposal make sense to you?

- Offers. A good offer would look like this: "I want the bounty, I want to do this thing within two
months, it will be tested with the following NLEs ..., will work correctly with the following effects ...."
Or like this: "I will do it with no effects (you can only have cuts of clips), and will
test it on Vegas Pro only, for this I want $300 instead of the full bounty"

Any thoughts?

Thank you for making this offer Skubi - the Kdenlive community is starting to gather some steam as evidenced by your enthusiasm.

I will cross post this to the Kdenlive Dev-group. Presently, the focus is on getting Kdenlive ready for the KDE-5 rollout. There's also an upcoming effort to rework the Kdenlive project file format to more closely follow the mechanisms employed by MLT/Shotcut. I expect that this work would take precedence over any interoperability w/ AAF.

My initial thoughts on this are that an associated program could be created to accomplish the desired interoperability w/ AAF. The program would ingest a Kdenlive project and spit out an AAF document. Ideally, we would setup a rule-based mechanism that defines the transposition that takes place for each element in a Kdenlive project.

If that's all it takes, it may not be too difficult to accomplish this - time consuming though. Unfortunately, this feature will have to wait until the Kdenlive project file format gets reworked - IMO.

i am very interested in trying to find a solution to work with other editors as well. i started trying to first define a protocol or a way to address this issue. check it out:

https://bugs.freedesktop.org/show_bug.cgi?id=83111

your input would be much appreciated. lets join forces.

also check out this mlt to blender script: (it uses CMX 3600 EDL format )

https://eyeframeconverter.wordpress.com/mlt2edl/

cheers

Thank you for the answers to this thread.

By modifying some kdenlive->EDL converter found on the net, I obtained a script
that transforms a multi-track kdenlive project into EDLs that can be understood by
Vegas Pro. This is very limited, has hardcoded stuff in it, and is generally
very, very quick and dirty. Can be used only by those who understand python and
are willing to get their hands dirty tweaking the script. I am posting the script, because
of the lack of better stuff (I hope that my bounty will result in better stuff).
