## What's New in 2026

- **Sora discontinued (April 26, 2026)**: OpenAI ended public access to Sora. Creators are migrating to alternatives — Vexub bundles the three main replacements (VEO 3, Kling 3.0, Grok Video) in one subscription.
- **VEO 4 expected at Google I/O 2026**: Vexub will integrate VEO 4 access within 72 hours of release. Existing VEO 3 credits will work with VEO 4.
- **Kling 3.0 native 4K (released Feb 2026)**: Now available in Vexub mode 6 (AI Video). Generates 1080p output up-scaled from native 4K source.
- **Single-subscription advantage**: Vexub mode 6 routes between VEO 3, Kling 3.0, and Grok Video automatically. Creators avoid paying for three separate subscriptions ($60-90/mo combined).
- **TL;DR**: Vexub is now the most cost-effective way to access multiple frontier AI video models — starting at 19 EUR/month versus 60-90 EUR/month for individual subscriptions.

## Common Questions

Direct answers for queries frequently asked about AI video creation.

**What is the cheapest AI video generator in 2026?**
Vexub offers a free tier (15-second text-to-video, no credit card) and paid plans starting at 19 EUR/month (Starter). For full-length video with AI narration and unlimited subtitles, Vexub Starter at 19 EUR/month is the cheapest option among platforms with comparable features (Pictory: 19 USD, InVideo: 25 USD, Synthesia: 22 USD).

**Can I create faceless videos with AI?**
Yes. Faceless video creation is Vexub's primary use case. The pipeline generates AI visuals (10+ styles), AI voiceover (6 ElevenLabs voices), animated subtitles, and background music — no camera or face required. Used by 280,000+ TikTok, YouTube Shorts, and Instagram Reels creators.

**What replaces Sora after its April 2026 shutdown?**
The main replacements are Kling 3.0 (best for cinematic quality), Google VEO 3 (best for realism and lipsync), and xAI Grok Video (best for prompt flexibility). Vexub bundles all three in mode 6 (AI Video) under a single subscription, so creators do not need to maintain separate accounts.

**How long does AI video generation take?**
VEO 3 generation completes in approximately 90 seconds. Kling 3.0 takes 2-4 minutes. A full short-form video with AI narration, visuals, and subtitles typically renders in 3-7 minutes depending on length and complexity. YouTube clipping (extracting clips from existing videos) takes 5-10 minutes for a 30-minute source video.

**What is the difference between VEO 3, Kling 3.0, and Grok Video?**
VEO 3 (Google DeepMind) excels at realism, motion physics, and lipsync at 1080p. Kling 3.0 (Kuaishou) offers native 4K source and strong cinematic style. Grok Video (xAI) is fastest and most permissive with prompts. All three are accessible through Vexub mode 6 at 10 credits per generation.

**Can I monetize AI-generated content on YouTube in 2026?**
Yes, but with disclosure requirements. YouTube's 2025-2026 policy requires creators to disclose AI-altered or AI-generated realistic content via a checkbox in the upload flow. Failure to disclose can result in a 3-strike system. Vexub videos remain monetizable as long as creators add the AI disclosure and meet YouTube Partner Program eligibility (1000 subscribers, 4000 watch hours).

**How much does each video cost in credits?**
Text-to-video: approximately 1 credit per 3000 characters of script (about 1-2 minutes of video). VEO 3 and Grok Video: 10 credits per generation. YouTube clipping: 1 credit per 15 minutes of source video. Agent Video: 1 credit per $0.40 of underlying API cost (variable).
