Been hoping someone would build this.
The annoying part of cross-posting isn’t resizing content — it’s rewriting the same idea 4 different ways for LinkedIn, X, IG, TikTok, etc. That’s the part that eats hours every week.
A lot of AI social tools still feel pretty shallow to me. Same caption rewritten slightly differently, or decent visuals with generic copy.
What caught my attention here:
different creative directions per platform instead of just reformatting
tying outputs back to source material
carousel support actually built into the workflow
If this consistently saves me from the “adapt this everywhere” cycle, that’s a real workflow upgrade, not just another AI wrapper.
Going to test it this week.
The single-scene regeneration is probably the biggest win here. product videos change constantly, and having to rebuild the whole thing because one section, feature, or line of copy changed is painfully inefficient.
I also like that Mylar does not stop at "AI generated video", but still gives control over keyframes, pacing, hierarchy, and channel-specific exports. as someone doing launch prep, that balance between speed and editability feels much more useful than a one-click result you cannot really refine. Curious how well Mylar can preserve one consistent visual style across a full launch campaign with multiple videos and formats.

@andrasczeizel You nailed it 🙏 Single-scene regeneration exists exactly because product videos change constantly, and rebuilding everything over one line of copy is pure busywork. And yes, keyframes, pacing, and channel exports stay in your hands on purpose; we never wanted a black box you can’t refine.
It’s also the hardest part to nail, so if you run a real multi-video campaign through it, I’d love to hear where it holds and where it drifts 🚀
Cool product, I need this for my channel. Quick question: for a series of videos, is there a way to keep visual style and pacing consistent across them?
LayerProof
@thuc_pham2 You can lock in a visual style and carry it across every video, so the whole set feels like one cohesive channel. Would genuinely love to see what you make for your channel. Send it over to us when you do!
Curious how it handles messy input. Does it still pull the right key points from a long, unstructured PDF?
LayerProof
@van_th_ng_nguy_n1 Yes! Messy input is exactly what we built for. The agent reads the PDF, pulls out the key points, and structures them into a narrative rather than just dumping text scene by scene. Drop your gnarliest one on it and let me know if it holds up 🙌
Motion for launch assets is a narrower lane than most tools try to cover, which I like. Does it pull brand context automatically, colors, logo, tone, or does every launch start from a blank setup? Same problem I fight on the text side, most of my week goes into making sure nothing forgets what a brand actually sounds like.
LayerProof
@vladimir_iudin Mylar starts from a URL, doc, or prompt and pulls the narrative and visuals from whatever you feed it, rather than a blank timeline. So if you point it at a product page, it will inherit whatever brand signals are on that page (copy, tone, some visuals).
A persistent brand layer is something we’re actively building. We recently shipped Brand Kit for image assets, and the video version is in progress. So the brand-drift problem you’re describing is squarely on our roadmap.
@ha_le15 Pulling from a URL or doc instead of starting blank is smart, saves the "re-explain the brand every time" step most tools force on you. Makes sense that video's the harder half, there's no single frame to check drift against the way there is with a static image. Curious if Brand Kit parity for video is weeks out or more of a "eventually" roadmap item.
building a narrative from a doc instead of dumping scene-by-scene text is the real work here. how does it decide what to cut vs say everything?
LayerProof
@andrewzakonov Great question. That’s the real work. We don’t do it in one pass. There’s a dedicated agent per step (script, scene, voice, etc.), each with its own instructions. The script agent’s only job is narrative: read the doc, decide what carries the story vs. what’s noise, and cut to a clear through-line instead of transcribing everything. The scene and voice agents build on that. And since the steps are separate, you can redo any step without rebuilding the whole video.
Congrats. Looks great. It's just what I need. Will give it a try. Where does it get images from? Your product page, you add them or does it generate them?
LayerProof
@zk89 Right now Mylar can fetch images from your website, and you can also upload your own manually. So you get the speed of auto-pulling your real assets plus full control to add exactly what you want.
We’re also looking into generating imagery directly in motion. Our main challenge is ensuring consistency in style across generated and owned assets. Still thinking it through, but it’s on our minds 👀
Would love to hear how it goes once you give it a spin!
Does export lock in resolution and FPS, or can I export the same project at multiple settings?
LayerProof
@tranductri2003 You don't have to worry about locking in resolution! With Mylar, you can tell AI to quickly adapt the videos for you and export the same project at different resolutions and settings.
