Text-to-Video Generation
Sora (OpenAI)
OpenAI's Sora generates up to 20-second cinematic video clips from text prompts or images. The output quality for complex scenes — camera movement, lighting, realistic physics — is significantly ahead of competitors. Available to ChatGPT Plus and Pro subscribers. Still limited in resolution and duration, but the trajectory is steep.
Pricing: Included with ChatGPT Plus ($20/month). Priority generation with Pro ($200/month).
Best for: Concept visualization, social media clips, creative directors testing ideas quickly.
Runway Gen-3 Alpha
Runway is the professional's choice for AI video generation. Gen-3 Alpha produces the most stylistically controllable output of any model — you can specify camera movement, lighting conditions, and visual style with precision. Its image-to-video feature is particularly strong for product visualization and creative projects.
Pricing: Free tier (125 credits). Standard at $15/month (625 credits). Unlimited at $95/month.
Best for: Creative professionals, filmmakers, marketers needing controlled visual output.
AI Video Editing
Descript
Descript edits video by editing a transcript. Delete a sentence from the text, the corresponding clip disappears. Its AI features include automatic filler-word removal, studio sound (background noise elimination), and "Overdub" — correcting spoken mistakes by typing new text in your voice. The most accessible professional editing tool available.
Pricing: Free tier. Creator at $24/month. Business at $40/month.
Best for: YouTubers, podcasters, anyone who edits talking-head or interview video.
Video Repurposing
Opus Clip
Opus Clip takes a long video and auto-generates short-form clips for TikTok, Reels, and Shorts. Its AI identifies the most engaging moments using virality scoring, adds animated captions, and crops to vertical format automatically. For anyone with existing long-form content, it's the highest-ROI AI tool in the video category.
Pricing: Free tier (60 minutes/month). Pro at $19/month.
AI Avatars and Presenters
HeyGen
HeyGen generates photorealistic AI avatar videos from a script. Choose from 100+ pre-built avatars or create one from your own likeness. For training videos, product demos, and explainers that don't require a camera, HeyGen cuts production time from days to minutes. Its video translation feature translates a presenter's video into another language while lip-syncing to the new audio.
Pricing: Free tier (1 video/month). Essential at $24/month.
Best for: Corporate training, product demos, international content, scale content production without on-camera talent.
Captions and Accessibility
Submagic / Captions
Both tools automatically generate animated, stylized captions for short-form video — the kind you see on every TikTok. The AI identifies the current word, animates it, and applies the styling creators expect from viral content. What used to take hours of manual SRT editing takes seconds.
Pricing: Both offer free tiers. Paid plans from $17/month.
AI Voice for Video
ElevenLabs
ElevenLabs produces AI voiceover that passes for human at the highest tier. Clone your own voice for consistent narration across videos, or use their library of 1,000+ voices. For explainers, ads, and course content, it eliminates the recording setup entirely.
Pricing: Free (10,000 characters/month). Starter at $5/month. Creator at $22/month.
