Local AI video editing in 2025 — faster b-roll, captions, and cleanup
You can now generate b‑roll, smart captions, and remove noise locally. Here’s the gear and software setup that actually works.
What’s possible locally
- B‑roll generation at 720p/1080p with short prompts.
- Smart captions and speaker labels with diarization.
- Hum removal and voice isolation that’s good enough for YouTube.
Hardware sweet spot
- 16–24GB VRAM for snappy preview.
- Fast NVMe; keep footage and cache on separate drives if possible.
- Quiet cooling to avoid mic noise.
Software stack
- Local captioning and translate; export SRT and burn‑in.
- Effect chains: denoise → level → caption overlay → b‑roll cuts.
- Color last; AI can mislead if applied before balance.
Workflow tips
- Generate b‑roll in batches; pick the best 10s loops.
- Keep a “graphics” bin for reusable lower thirds and calls to action.
- Test renders at 0.5x speed to spot caption drift.
FAQs
- Is 8GB VRAM enough? For 1080p workflows with modest generation, yes.
- Can I run it on a laptop? If you have 16GB+ VRAM or you accept slower previews.
