Pick the right engine for your brief: runtime, motion quality, and how fast you need iterations. Below is a practical breakdown with real sample outputs you can preview in LetsTok Studio.

Guide
Not every AI video model is interchangeable. Some are tuned for short, punchy product reveals; others shine when you need more time on screen for storytelling, demos, or multiple beats in one clip.
In LetsTok’s e-commerce video flow you can switch between engines before you generate. Use this guide to narrow the field: start from your target length and placement (e.g. Meta, TikTok, YouTube Shorts), then weigh motion fidelity versus iteration speed and cost.
The samples below are the same previews we surface in the product for each tier — so what you see here is representative of what you’ll get in the studio.
Samples are vertical (9:16), typical for paid social. Use the link under each clip to open the full LetsTok Studio preview player.
Lean, fast generations for simple product motion
Veo Lite is aimed at quick-turn e-commerce ads: a clear hero shot, light camera movement, and enough time for a hook plus product payoff in about eight seconds.
Choose it when you’re testing many hooks or formats, need predictable runtime for short placements, and want to keep generations efficient while still looking polished.
Same eight-second format with a faster iteration profile
Veo Fast stays in the same eight-second lane as Lite but is optimized for speed when you’re batching ideas or racing a launch calendar.
Use it when velocity matters most — more variants per hour, same vertical format — and you’re still building ads that lean on strong product framing rather than long narrative scenes.
Extra room for pacing and on-screen story beats
Sora 2 Standard unlocks longer cuts — ten or fifteen seconds — so you can let the product breathe, add a second idea, or sync more naturally with voiceover and music.
Reach for Standard when eight seconds feels tight, you care about smoother motion and scene coherence, and you’re okay with a step up in generation weight compared to the Veo lane.
Highest fidelity when the creative needs to carry the brand
Sora 2 Pro targets premium outcomes: longer options (fifteen or twenty-five seconds) and the headroom for richer lighting, detail, and camera language.
Pick Pro for flagship campaigns, hero products, or any ad where viewers should feel a “big budget” look — especially when the final edit will be reused across channels.
Strong motion alternative in the mid-length band
Seedance 2 sits in a similar duration band to Sora Standard (ten or fifteen seconds) and is useful when you want another aesthetic or motion signature for the same media plan.
Try it alongside Sora Standard in split tests: same script and product, different engine — then keep the winner that converts for your account.
Alternative look and motion from xAI’s video model
Grok video is another option when you want a fresh creative direction on the same product and script — useful for split tests against Veo or Sora outputs.
Use it when you’re exploring style diversity across your ad account: generate the same brief on Grok, compare pacing and visuals, then scale the variant that wins on CTR or CPA.
Use this as a default decision order, then refine with your own data.
LetsTok keeps pricing transparent — compare plans and run a few generations on the tier that fits your volume.
