Resolve API - Working with Multiple Tracks in Timeline

I've been racking my brain on this for days. How do you add clips to a video track other than the bottom one?

This should be simple, but I've spent hours going through the README, and I've come up with nothing. The only thing I could find was the function call below, but it causes Resolve to freeze:
media_pool.AppendToTimeline({
"mediaPoolItem": media_pool.GetRootFolder().GetClipList()[0],
"startFrame": 0,
"endFrame": 30,
"mediaType": 1,
"trackIndex": 2,
"recordFrame": 90012})

Has anyone been able to add clips to different tracks in the timeline?

Bump. Anyone?

I've had success using this structure in Lua to append to timeline:

Code: Select all

            subClip = {}
            subClip["mediaPoolItem"] = clip
            subClip["startFrame"] = 0
            subClip["endFrame"] = clipFrames
            subClip["recordFrame"] = StartTimeCodeInFrames -- StartTime in frames
            subClip["trackIndex"] = trackIndexSelected -- select which track
            subClip["mediaType"] = 1 -- video only
   

            mediaPool:AppendToTimeline({ subClip })
