Premiere Pro doesn’t export markers of 0 duration to FCP XML

While doing research for a commission that I recently received, I found out that Premiere Pro CS6 does not export markers of 0 duration to FCP XML. This proved to be a bit of a surprise, and also turned out to be a major flaw for the software that I am supposed to develop.

I had to find out the way to automatically convert all the markers into the ones with specified duration. Fortunately, as I wrote many times, Premiere Pro’s project file itself is an XML. Of course, as it was kindly pointed out to me, it’s pretty complicated in comparison to the exchange standard promoted by Apple, however it is still possible to dabble in it, and if one knows what one is doing, to fix a thing or two.

Marker duration proved to be a relatively uncomplicated fix.

In the project file, markers are wrapped into the <DVAMarker> tag. What is present inside, is an object written down in JavaScript Object Notation. I’m not going to elaborate on this here, either you know what it is, or you most likely wouldn’t care. Suffice to say, that the typical 0 duration marker looks like this:

<DVAMarker>{“DVAMarker”: {“mMarkerID”: “3cd853f0-c855-46de-925c-f89998aade87″, “mStartTime”: {“ticks”: 6238632960000}, “mType”: “Comment”}}</DVAMarker>

and the typical 1 duration marker looks like this:

<DVAMarker>{“DVAMarker”: {“mComment”: “kjhkjhkjhj”, “mCuePointType”: “Event”, “mDuration”: {“ticks”: 10160640000}, “mMarkerID”: “7583ba75-81f5-4ef2-a810-399786f3a75d”, “mStartTime”: {“ticks”: 4049893512000}, “mType”: “Comment”}}</DVAMarker>

As you can see, the mDuration property is missing in the 0 duration marker, and the duration 1 marker is also labeled as “Event” in the “mCuePointType” property. It turns out, that it is enough to insert the following string:

“mDuration”: {“ticks”: 10160640000},

right after the second curly brace to create the proper 1 frame marker that gets exported. You can do it in your favourite text editor yourself, and then the corrected marker would look like this:

<DVAMarker>{“DVAMarker”: {“mDuration”: {“ticks”: 10160640000}, “mMarkerID”: “3cd853f0-c855-46de-925c-f89998aade87″, “mStartTime”: {“ticks”: 6238632960000}, “mType”: “Comment”}}</DVAMarker>

Granted, it’s a bit tedious to do it by hand for hundreds of markers (as was my client’s request), and unless Adobe decides to fix it in the near future (I already filed a bug report), or Josh from releases it first on his own, some time at the beginning of the next year I might have a piece of software that will automatically convert the 0 duration markers to 1 frame ones, so that they get easily exported to FCP XML. I understand that this is a pretty rare problem, but perhaps there are a few of you who could benefit from this solution.

The main bugger? Most likely it will be Windows only, unless there is specific interest for the Mac platform for something like this.
