I have been looking for a script to be able to import some media, which I usually use during my compositions.
I found a script by Edward Troxel that did this, but using already present tracks on the timeline.
I am not very familiar with everything related to scripting, but taking a cue from that and also based on other scripts I had, I modified it to be able to get both the tracks and the media.
The problem I have now, however, is that the imported media has both video and audio ungrouped.
If anyone can give me a tip on how I could fix this, I would appreciate it!
I apologize for my less than perfect English!
