Script access to timeline items

Im trying to programmatically set keyframes for timeline clips, for things like Transform->Position/Zoom and Composite->Opacity

Using the following script I can access the timeline item, but none of the members of 'Timeline item' (GetDuration, GetFlags, GetMarkers, etc) appear to point to these properties. How can I modify these values?

It would also be useful if, instead of "timeline.GetItemsInTrack("video",1)" I could use something like "GetCurrentlySelectedItem()" but that also seems un-doable.

Code: Select all

import imp
dr = imp.load_source('DaVinciResolveScript', 'C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\Developer\Scripting\Modules\DaVinciResolveScript.py')
resolve = dr.scriptapp('Resolve')

projectManager = resolve.GetProjectManager()
project = projectManager.GetCurrentProject()
timeline = project.GetCurrentTimeline()

items = timeline.GetItemsInTrack("video",1)
item = items[1]
print(item.GetName()) #Item successfully acquired


I'm trying to do something similar. Did you find a solution?

Those item properties are not exposed via the API.

I responded to your question in another thread, but are you trying to access the current item, not the current clip? The OP is talking about accessing the timeline item.

To access the current item you use GetCurrentVideoItem() on the timeline instance.

To access the current item you use GetCurrentVideoItem() on the timeline instance.

GetCurrentVideoItem() retrieves the topmost item at the playhead position - not the currently selected clip!

I would like to be able to access the selected clip(s) in the timeline.
It would also be nice to be able to retrieve the selected clip(s) in a bin.

So please BMD, add the following to the API:
- MediaPool.GetSelectedItems()
- Timeline.GetSelectedItems()

For timeline-items that are Multicams,
is there any way to find out what camera angle and position within the Multicam they are?

As far as I know, there is no direct way to determine the camera or angle used in the timeline.
For the MediaPool item, there is a property for "Angle" and "Camera #"

Code: Select all

item.GetProperty('Angle')

or

Code: Select all

item.GetProperty('Camera #')

but unfortunately the clips in the timeline refer to the multi-camera clip and not to the source clips.

But there is a small workaround:

The angle or camera# (depending on the setting when creating a multi-camera clip)
is appended to the name of the timeline element.

So you can use this python code to get the information:

Code: Select all

import DaVinciResolveScript
resolve = DaVinciResolveScript.scriptapp('Resolve')
project_manager = resolve.GetProjectManager()
project = project_manager.GetCurrentProject()
current_timeline = project.GetCurrentTimeline()
current_item = current_timeline.GetCurrentVideoItem()
current_mp_item = current_item.GetMediaPoolItem()
clipname = current_item.GetName()
multiclipname = current_mp_item.GetName()
angle = clipname.replace(multiclipname  + " - ", "")
print(angle)


Very indirect and not exactly robust. But it could actually solve half of what we need.

Currently we access the database directly because the API is way too limited.

The Properties are clip-metadata and not Multicam track names.
So we can't rely on them even to be non-blank. Let alone correct or unique.
Way too often a camera is moved to a different position ad-hoc without anyone entering the
metadata screen with the tiny on-screen keyboard while a live show is about to start any second.
(It's more important to check focus, be level with the stage, adjust interkom and make sure jam-syncing timecode was not forgotten about at that moment. ...and check that the internal micophone in not off, as a backup to timecode.)

The Properties are clip-metadata and not Multicam track names.

Yes, but Davinci uses the clip-metadata to generate the Multicam Clip Name (in timeline).

So we can't rely on them even to be non-blank.

The same applies to the metadata - if it is not filled in correctly...
