_⚠️ Potential issue_ | _🔴 Critical_

**Critical bug: Variable shadowing in list comprehension.**

The loop variable `final_video_path` shadows the outer `final_video_path` variable defined on line 301. After the list comprehension executes, `final_video_path` will contain the last element from `all_video_paths` instead of the intended output path `"final_video.mp4"`.

```diff
-        video_clips = [VideoFileClip(final_video_path)
-                       for final_video_path in all_video_paths]
+        video_clips = [VideoFileClip(video_path)
+                       for video_path in all_video_paths]
```

In
`@issues/todo/ViMax_Complete_Integration_Package/src/pipelines/idea2video_pipeline.py`
around lines 306 - 307, The list comprehension that builds video_clips uses the
loop variable final_video_path which shadows the outer final_video_path variable
(defined near the creation of "final_video.mp4"), causing the outer variable to
be overwritten; change the comprehension to use a different loop variable name
(e.g., path or clip_path) when iterating over all_video_paths so the outer
final_video_path remains `"final_video.mp4"` and then use VideoFileClip(path) to
build video_clips.
