EbSynth
Pros
- + Propagates painted keyframes across a shot with the style preserved literally — a single strong keyframe carried a long way on slow footage in my tests
- + Vendor is explicit that propagation uses texture synthesis, not generative AI or external training data — rare transparency in this category
- + Free plan includes all core functions with no time limit, and the browser workspace (timeline, multi-track keyframe layers, built-in painting) removes the old image-sequence-folder friction
- + Multi-track workflow with alpha keyframes lets you time background, face and eyes independently — this is what makes professional-grade results possible
- + Studio plan runs fully local on Windows for NDA work, an option almost no browser-based stylization tool offers
Cons
- - Propagation degrades into patch artifacts on fast motion and occlusion, and fixing it means hand-placing more keyframes — a real skill ceiling
- - Free exports cap at 720p MP4; 1080p/4K and PNG-with-alpha require Pro at $20/month
- - Fully offline processing costs $200/month per seat (Studio), a steep jump from Pro for solo users with privacy needs
- - No automatic masking, tracking or cut detection — every shot is broken up and masked by hand
- - Support ecosystem is thin: one official tutorial, no verifiable community forum, no plugin ecosystem
Runway ML
Pros
- + Aleph 2.0 edits footage you already have — I produced three campaign variants from one hero shot by changing background and product while the performance held
- + Deepest toolchain in the category: generation, workflows, canvas, Act-Two performance capture, ProRes/PNG export, and a documented API
- + Credit math is transparent: 12 credits/second for Gen-4.5 published, top-ups flat at $0.01 each with 1,000 minimum and no expiry
- + Honest help-center language — Runway itself calls Standard 'light, exploratory usage', which matched my measured yield of 3–4 usable shots/month
- + Strong institutional footing: founded 2018, ~$1.05B raised, $5.3B valuation (Feb 2026), Runway Studios and an AI film festival for ecosystem gravity
Cons
- - Expensive per finished second — Standard's 625 credits buy ~52s of Gen-4.5 before retries, so Pro ($28/mo annual) is the practical floor
- - Flagship generation is capped at 720p in-app while Aleph edits at 1080p; resolution runs backwards through the workflow
- - No native long-form generation (2–10s Gen-4.5 clips) — narrative sequences need external assembly
- - The Unlimited plan stopped selling on 1 June 2026 and its Unlimited/Explore Mode replacement excludes Gen-4.5 and covers a model list Runway says may change
- - Queues are noticeably slower at peak on lower tiers; priority is effectively a paid feature
