By the way, since moderator RWAV has introduced BlackMagic Fusion as one possible option for motion tracking with Lightworks, just one little detail added from my side, which might or might not be important to those who want to follow the suggestion: The latest free version of Fusion is Fusion 9. The successor, Fusion 16, isn't free anymore at least not stand alone. Fusion 16 is available as paid Studio version stand alone or integrated as module into the free version of DaVinci Resolve 16.

Instead of invoking Blender directly, you need to invoke some user written application which translates what Lightworks writes into a plain text file into a Blender command line, which follows the rules below, and starts Blender afterwards.

docs.blender.org/manual/en/latest/advanced/command_line/arguments.html

I don't have any, maybe others have?

I just found that Blender is able to execute Python scripts on startup.

docs.blender.org/api/current/info_overview.html

I can imagine, if you are familiar with Python, which I am not, that creating something that parses the trivial text file created by Lightworks in order to create Blender commands accordingly shouldn't be rocket science?

oh! I am familiar with it but not very much but maybe RWAV is? I am not sure but I guess I will just wait, because I posted a question on the blender stack exchange so i will see if anyone responds.

(sorry for horrible grammar)

The way you use an assistant application is:

1. Add the effect to your timeline.
2. On the fx setting panel click the List Sources button.
3. The text file will open showing the clip file name(s) the fx is effecting and the frames from the clips that are used in the fx.
4. Click the Launch button.
5. The app will open just as if you launched it from the OS icon.
6. Load the clip(s) into the app.
7. Restrict the app to only affect the frames shown in the Sources List file.
8. Use the functions of the app to create the effect.
9. Render the affected frames into the folder set up in the Lightworks assistant app setup using a codec compatible with Lightworks.
10. Close the assistant app.
11. In Lightworks, right click the effect in the timeline and choose to replace the effect with the rendered file. The folder will open.
12. Select the rendered file.
Done.

This was from memory from use many years ago, so actual steps might be a little different.

I find, it would be really great, not only for the users of Lightworks Free, if we would have a properly working interface to Blender that uses the EDL data from Lightworks to invoke Blender with the proper media already in place.

Fingers crossed!

The assistant application feature isn't even documented in the current V14.5 user guide, but apparently it sill exists, don't know what that means.

Have been using Fusion since V2 in he late 1990's. V7 is more than enough for normal LW users and will run on quite modest computers - but it was a Win only.

BMD provide downloads of all versions - so if anyone wants the last V9 here are the links.
