Frequently asked

How is this different from a regular video maker?+
Two things. First, the video generation is shaped for 9:16 vertical from the prompt — no awkward cropping. Second, Caption Studio inside getvivix auto-generates burned-in captions sized correctly for Shorts / Reels / TikTok in seconds, with full editing control.
Which models support vertical 9:16?+
Veo 3.1 + Veo 3.1 Lite, Sora 2, Kling VIDEO 3.0/O3, Runway Gen-4.5, Wan 2.7, Seedance 2.0 + Fast, MiniMax Hailuo 2.3 + Fast, LTX-2.3, Vidu Q3 Turbo, HappyHorse 1.0. All let you pick portrait aspect ratio at generation time.
Can I auto-caption a clip I already have?+
Yes. Upload your MP4 to Caption Studio, transcribe with one click (using Whisper), and we burn in captions matched to the speaker's timing. You get clip credits separate from your normal credits — every plan includes a clip-credit allowance.
How long can the videos be?+
Most generations are 5-10 seconds — perfect for Shorts. For longer assemblies, generate multiple clips and stitch them together in Caption Studio.
Do generations include sound?+
Yes for Veo, Sora, Kling, Seedance 2.0, LTX-2.3, Hailuo 2.3, Vidu Q3 — all generate native audio. For older silent models, getvivix TTS (ElevenLabs Flash, MiniMax Speech) gives you voice-overs you can layer in Caption Studio.
Is the output ready to upload?+
Yes. Output is MP4 in the aspect ratio you picked, with optional burned-in captions. Drag-and-drop into YouTube Shorts, TikTok, Instagram Reels — no further conversion.
Is this a free YouTube Shorts maker?+
There's a real free tier: 30 credits when you sign up plus 30 more dropped daily, no card required. That's enough to generate and caption short clips every day. Paid plans add more credits, faster queues, and a commercial-use license. The exact credit cost for each model is shown before you hit generate, so nothing surprises you.
Can this work as an AI YouTube Shorts generator from text?+
Yes. Type a description of the scene you want and a text-to-video model builds the 9:16 clip — no footage needed. Veo 3.1, Sora 2, Kling 3.0, Seedance 2.0, Wan 2.7 and more all run from a text prompt. You see the credit cost for the model you picked before generating, then send the result straight to Caption Studio.
Can I turn a long video into Shorts with AI?+
You can repurpose long-form footage: upload your MP4 to Caption Studio, Whisper transcribes it, then you trim the moments worth clipping, crop to 9:16 with auto face-tracking, and export each as its own Short. For fully AI clips you generate fresh 5-10 second scenes instead. We don't auto-detect viral moments for you yet — you pick the segments.
How many models can I use to make Shorts?+
getvivix hosts 100+ image, video, and audio models in one studio on a single subscription — over a dozen of them generate 9:16 vertical video with native audio. You can switch between Veo, Sora, Kling, Seedance, Wan, Hailuo and others without leaving the page or paying for separate tools.
