The verdict
Which one should you pick?
ChatGPT
Pick it for
- Writing shot lists, treatments, pitch decks and scripts with file output
- Generating look-development stills and poster or title-card mockups with readable text
- Analysing budget, schedule or audience spreadsheets with the Data plugin
Stands out
- Stills with reasoning: the Images 2.x line plans the composition and checks object counts and prompt constraints before drawing, and renders legible text, which helps with posters, title cards and storyboard labels.
- Agent that produces files: ChatGPT Work outputs real .docx, spreadsheet, slide and small web app deliverables from connected apps, not just chat answers.
Watch out
- No video generation after the Sora shutdown; shot generation needs another tool
- Plan limits are dynamic and hard to predict, especially for agent runs
Gemini
Pick it for
- Previs and fast B-roll drafts from a script line
- Extending a good 10-second shot into a longer continuous take
- Research and treatment writing with Deep Research before a shoot
Stands out
- Video with synced audio from the same chat box that does research and image editing, no separate tool to switch into
- Omni can use a short existing clip (up to 3 s) as a reference to keep a character or look consistent, and extend a scene from its last 10 seconds
Watch out
- Clips are short; scene extension is needed for anything over 10 seconds
- Video is metered by Flow credits, so heavy iteration runs out fast on Plus
Kling AI
Pick it for
- Character-driven short films that need the same actor across many shots
- Previs and storyboard visualisation from shot-by-shot prompts
- Multi-language talking-head and dubbed social content
Stands out
- Video 3.0 Omni reference system: carries a character's look, expressions and voice traits from reference clips into new shots
- Storyboarding sets duration, shot size, perspective and camera movement per shot, which few generators expose this directly
Watch out
- Free output is watermarked and not for commercial use
- Lip-sync and voice are less of a focus than dedicated voice tools (ElevenLabs, HeyGen)
Google Veo 3
Pick it for
- Previs and animatics for narrative scenes where audio matters from the first pass
- Short commercial or music-video B-roll at 4K on 8-second shots
- Exploring shot options cheaply with Veo 3.1 Lite before paying for Standard
Stands out
- Native audio is generated with the picture (dialogue, SFX, ambience) and is included in the listed per-second price, not a separate charge.
- 4K output on 8-second clips, where most competitors top out at 1080p in the same price band (Veo's own 4K tier costs $0.60 per second).
Watch out
- 8-second maximum per generation; longer shots need extensions or stitching
- Extension only works at 720p and only on Veo-generated footage
