Creator Variant Studio — Batch Branded Images & Videos

One approved asset set. Consistent images and short videos.

Capabilities

A local production tool for social-content freelancers, small brands and creators who already have their assets and copy. Product spotlight, insight cards and event announcement templates rearrange content for 9:16, 1:1 and 16:9. Animated clips reveal separate elements over time and can include your short source video and one optional audio track.

Reuse brand colors, logo, licensed font, weight, spacing and CTA style. Browser forms and CLI share measured text/font checks, preview approval, per-job status, cancellation and verified partial reruns. Long text and missing glyphs are blocked rather than silently changed. English and Traditional Chinese interfaces, full Agent workflows and manuals are included in the same purchase.

Input → output

Five synthetic product visuals × two approved headlines × three ratios = 30 combinations. Each produces one PNG and one MP4: 60 final media files, plus a local gallery and per-job status. Change one headline: three affected final jobs rerender, 27 valid jobs are reused after hashes and full video decoding checks. Previews are regenerated for review. Exact price, date and CTA copy is preserved.

Use cases: recurring social batches, client content variants, product launches, educational tip cards and event announcements.

Before buying

Terminal setup is required: Python 3.12+, pinned Pillow/fonttools dependencies, FFmpeg/ffprobe with working H.264 encoding, and a licensed font you supply. No native one-click installer. Tested on macOS Apple Silicon; Windows and Linux are not acceptance-tested. Font and FFmpeg binaries are not bundled.

PNG: 1080×1920, 1080×1080, 1920×1080. MP4: H.264/yuv420p, 30 fps, 6/10/15 seconds; optional AAC audio. Maximum 10 items, two headlines each, 30 jobs and 450 output seconds per batch. JPEG/PNG/WebP ≤24 MP; SDR H.264 MP4 source video ≤60 seconds. HDR is refused. One audio track, no mixing or loudness guarantee.

This fixed-template workflow does not generate footage, write copy, provide a freeform timeline, import Canva templates or synthesize speech. It does not guarantee marketing results.

Real validation

45 automated tests passed. Three templates × three formats × two languages produced 18 PNG and 18 MP4. The 30-job test produced 60 formal media files in 256.598 seconds on an Apple M3 with 24 GiB RAM, including decode verification. Changing one headline rerendered exactly three jobs and reused 27 in 27.548 seconds, excluding new previews. Timings are observations, not a hardware-independent promise. A real six-second audio sample was listened to and confirmed normal. Actual bilingual demo images and videos are included in examples/rendered/.

FAQ

Does it write or translate my copy? No. Supply approved text. Interface language and content language are independent.

Do I need a paid API or subscription? No required media API, server or subscription. Setup, computing/storage and an optional AI client have their own costs.

Can I deliver the work to clients? Yes, rendered media can be used commercially under the original-product license. Do not resell or redistribute the tool/templates.

How do I start? Read docs/en/README.md, install dependencies, run doctor with your licensed font, then init-demo. Review previews before approving a final render.

Privacy, rights and support

The renderer runs locally with no telemetry or remote media URLs. Installation may use the internet; an AI client has its own provider/privacy behavior. The UI binds loopback only. Delivery ZIPs contain finished media and a gallery, excluding sources, fonts and private project records. Visible content may still identify people; this is not an anonymization tool.

Use authorized media, copy, logos, music and fonts. No impersonation, fake endorsements or deceptive biometric media. Review output before publishing. Future development is not promised; updates published to this same Agent remain free to existing Download buyers under platform policy.

Launch test price: US$29.99, Download, one-time purchase, same for both languages. Support: [email protected]. Send only safe synthetic reproductions and error codes, never private customer files or credentials.
