Four video models ship on Cravim today. We spent a week generating 200 identical prompts across Veo 3.1, Veo 3.1 Fast, Veo 3, and PixVerse v4.5 to see which one actually wins on what. Spoiler: they're all good at different things.
Test methodology
200 prompts split across five categories: product shots, food, people, abstract B-roll, and text-heavy branded content. Each prompt run on all four models with identical parameters (8 seconds, 16:9, aspectRatio-appropriate framing).
Three of us scored each output blind on a 1-5 scale across four axes: motion coherence, visual fidelity, prompt accuracy, and the feel of "finished" vs "janky".
Veo 3.1 — the new benchmark
Average score across all four axes: 4.2. Motion coherence is the big upgrade over 3.0 — camera pans feel intentional, characters don't morph between frames, and the model genuinely seems to understand cause and effect (a ball rolls, lands, bounces once, stops).
Native audio is also real now. Generated voiceovers sync to lip movement. Ambient audio (coffee shop chatter, street noise, ocean waves) matches the scene. This alone closes most of the gap between generated video and filmed video.
Veo 3.1 Fast — the pragmatic choice
Average score: 3.8. Ships in ~30 seconds instead of ~75 for full Veo 3.1. Quality drop is real but small — you'd notice it side-by-side, but you wouldn't notice it on a feed.
This is our daily-driver model. Generate a dozen variations, pick the best, regenerate the winner on full Veo 3.1 if it's going to a high-visibility slot.
Veo 3 — the reliable veteran
Average score: 3.6. Motion is rougher than 3.1 and audio is less convincing. But on two specific categories — product spins and macro food shots — Veo 3 scored higher than 3.1 in our blind tests. We think its training data weighting differs in a way that still favors certain niches.
PixVerse v4.5 — the creative wildcard
Average score: 3.2 on our technical axes, but a separate "creativity" axis where PixVerse scored 4.6. It doesn't win on realism, but for stylized, experimental, or explicitly-non-realistic content — cartoon-inspired edits, dreamlike sequences, exaggerated motion — PixVerse is the better pick.
When to use which
Default to Veo 3.1 Fast. Upgrade to full Veo 3.1 for high-visibility finals. Consider Veo 3 specifically for product spins and close-up food. Reach for PixVerse when realism isn't the goal.
Chain models for longer videos: generate Scene 1 with Veo 3.1 for the hero moment, continue with Veo 3.1 Fast for coverage. FFmpeg stitches them seamlessly inside Studio's multi-clip flow.
The gap between generated video and shot-on-camera video closed in 2026. Veo 3.1 with native audio is genuinely finished work. The question is no longer whether AI video is good enough — it's which model fits which shot.
