Summary

AI-assisted video editing workflows for cutting, structuring, and augmenting real footage. Covers the full pipeline from raw capture through FFmpeg, Remotion, ElevenLabs, fal.ai, and final polish in Descript or CapCut. Use when the user wants to edit video, cut footage, create vl

1	# Video Editing
2
3	AI-assisted editing for real footage. Not generation from prompts. Editing existing video fast.
4
5	## When to Activate
6
7	- User wants to edit, cut, or structure video footage
8	- Turning long recordings into short-form content
9	- Building vlogs, tutorials, or demo videos from raw capture
10	- Adding overlays, subtitles, music, or voiceover to existing video
11	- Reframing video for different platforms (YouTube, TikTok, Instagram)
12	- User says "edit video", "cut this footage", "make a vlog", or "video workflow"
13
14	## Core Thesis
15
16	AI video editing is useful when you stop asking it to create the whole video and start using it to compress, structure, and augment real footage. The value is not generation. The value is compression.
17
18	## The Pipeline
19
20	```
21	Screen Studio / raw footage
22	→ Claude / Codex
23	→ FFmpeg
24	→ Remotion
25	→ ElevenLabs / fal.ai
26	→ Descript or CapCut
27	```
28
29	Each layer has a specific job. Do not skip layers. Do not try to make one tool do everything.
30
31	## Layer 1: Capture (Screen Studio / Raw Footage)
32
33	Collect the source material:
34	- Screen Studio: polished screen recordings for app demos, coding sessions, browser workflows
35	- Raw camera footage: vlog footage, interviews, event recordings
36	- Desktop capture via VideoDB: session recording with real-time context (see `videodb` skill)
37
38	Output: raw files ready for organization.
39
40	## Layer 2: Organization (Claude / Codex)
41
42	Use Claude Code or Codex to:
43	- Transcribe and label: generate transcript, identify topics and themes
44	- Plan structure: decide what stays, what gets cut, what order works
45	- Identify dead sections: find pauses, tangents, repeated takes
46	- Generate edit decision list: timestamps for cuts, segments to keep
47	- Scaffold FFmpeg and Remotion code: generate the commands and compositions
48
49	```
50	Example prompt:
51	"Here's the transcript of a 4-hour recording. Identify the 8 strongest segments
52	for a 24-minute vlog. Give me FFmpeg cut commands for each segment."
53	```
54
55	This layer is about structure, not final creative taste.
56
57	## Layer 3: Deterministic Cuts (FFmpeg)
58
59	FFmpeg handles the boring but critical work: splitting, trimming, concatenating, and preprocessing.
60
61	### Extract segment by timestamp
62
63	```bash
64	ffmpeg -i raw.mp4 -ss 00:12:30 -to 00:15:45 -c copy segment_01.mp4
65	```
66
67	### Batch cut from edit decision list
68
69	```bash
70	#!/bin/bash
71	# cuts.txt: start,end,label
72	while IFS=, read -r start end label; do
73	ffmpeg -i raw.mp4 -ss "$start" -to "$end" -c copy "segments/${label}.mp4"
74	done < cuts.txt
75	```
76
77	### Concatenate segments
78
79	```bash
80	# Create file list
81	for f in segments/*.mp4; do echo "file '$f'"; done > concat.txt
82	ffmpeg -f concat -safe 0 -i concat.txt -c copy assembled.mp4
83	```
84
85	### Create proxy for faster editing
86
87	```bash
88	ffmpeg -i raw.mp4 -vf "scale=960:-2" -c:v libx264 -preset ultrafast -crf 28 proxy.mp4
89	```
90
91	### Extract audio for transcription
92
93	```bash
94	ffmpeg -i raw.mp4 -vn -acodec pcm_s16le -ar 16000 audio.wav
95	```
96
97	### Normalize audio levels
98
99	```bash
100	ffmpeg -i segment.mp4 -af loudnorm=I=-16:TP=-1.5:LRA=11 -c:v copy normalized.mp4
101	```
102
103	## Layer 4: Programmable Composition (Remotion)
104
105	Remotion turns editing problems into composable code. Use it for things that traditional editors make painful:
106
107	### When to use Remotion
108
109	- Overlays: text, images, branding, lower thirds
110	- Data visualizations: charts, stats, animated numbers
111	- Motion graphics: transitions, explainer animations
112	- Composable scenes: reusable templates across videos
113	- Product demos: annotated screenshots, UI highlights
114
115	### Basic Remotion composition
116
117	```tsx
118	import { AbsoluteFill, Sequence, Video, useCurrentFrame } from "remotion";
119
120	export const VlogComposition: React.FC = () => {
121	const frame = useCurrentFrame();
122
123	return (
124	<AbsoluteFill>
125	{/* Main footage */}
126	<Sequence from={0} durationInFrames={300}>
127	<Video src="/segments/intro.mp4" />
128	</Sequence>
129
130	{/* Title overlay */}
131	<Sequence from={30} durationInFrames={90}>
132	<AbsoluteFill style={{
133	justifyContent: "center",
134	alignItems: "center",
135	}}>
136	<h1 style={{
137	fontSize: 72,
138	color: "white",
139	textShadow: "2px 2px 8px rgba(0,0,0,0.8)",
140	}}>
141	The AI Editing Stack
142	</h1>
143	</AbsoluteFill>
144	</Sequence>
145
146	{/* Next segment */}
147	<Sequence from={300} durationInFrames={450}>
148	<Video src="/segments/demo.mp4" />
149	</Sequence>
150	</AbsoluteFill>
151	);
152	};
153	```
154
155	### Render output
156
157	```bash
158	npx remotion render src/index.ts VlogComposition output.mp4
159	```
