<\/figure>\n<\/figure>\n\n\n\nBrush Strategy for Clean Animation<\/h2>\n\n\n\n
Most Motion Brush chaos starts before we ever touch the settings. It starts with where we paint.<\/p>\n\n\n\n
Think of the brush like seasoning: too much everywhere and the dish tastes blurry.<\/p>\n\n\n\n
What to mask<\/h3>\n\n\n\n
Our rule: paint motion on what actually needs to move, not the whole subject. That sounds obvious, but it’s easy to overpaint.<\/p>\n\n\n\n
For a clean animation mask, we usually:<\/p>\n\n\n\n
- \n
- Hair \/ fabric: Paint the edges and tips, not the whole head or body.<\/li>\n\n\n\n
- Product rotation: Paint outer contours and any reflections you want to shift.<\/li>\n\n\n\n
- Water \/ smoke: Paint the flow areas, leave solid surfaces unpainted.<\/li>\n<\/ul>\n\n\n\n
Here’s a simple workflow we use on almost every project:<\/p>\n\n\n\n
- \n
- Duplicate the frame (or import your still image) into PromeAI’s Image to Video<\/a><\/strong> tool.<\/li>\n<\/ol>\n\n\n\n
\n ![\"Using](\"https:\/\/www.promeai.pro\/blog\/wp-content\/uploads\/2026\/02\/1280X1280-1-4-1024x292.png\")
<\/figure>\n<\/figure>\n\n\n\n- \n
- Activate Motion Brush.<\/li>\n\n\n\n
- Do a rough first pass: paint only the zones that must move.<\/li>\n\n\n\n
- Hit preview at low settings just to see direction and coverage.<\/li>\n\n\n\n
- Refine the mask: erase any paint that’s creeping onto logo, text, eyes, or firm edges.<\/li>\n<\/ol>\n\n\n\n
Key idea: We’re drawing a permission zone for motion, not coloring in the subject like a coloring book.<\/p>\n\n\n\n
For more control, we often split the motion into layers:<\/p>\n\n\n\n
- \n
- Layer 1: Foreground subject movement (hair, clothes).<\/li>\n\n\n\n
- Layer 2: Secondary motion (background water, smoke, light).<\/li>\n<\/ul>\n\n\n\n
Run separate passes instead of trying to do everything in one mask. It keeps the motion cleaner and easier to tweak.<\/p>\n\n\n\n
Brush size selection<\/h3>\n\n\n\n
\n ![\"Detailed](\"https:\/\/www.promeai.pro\/blog\/wp-content\/uploads\/2026\/02\/1280X1280-3-1-1024x569.png\")
<\/figure>\n<\/figure>\n\n\n\nBrush size controls how precise your motion is and how much subject stability you keep.<\/p>\n\n\n\n
Our go\u2011to approach:<\/p>\n\n\n\n
- \n
- Fine details (eyelashes, logo edges, jewelry):<\/strong>\n
- \n
- Brush size: 5\u201310 px<\/li>\n\n\n\n
- Use this size near borders where you don’t want wobble.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Hair, fabric edges, small objects:<\/strong>\n
- \n
- Brush size: 20\u201340 px<\/li>\n\n\n\n
- This is our default for local motion control on people.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Large areas (water surface, big smoke plumes, sky):<\/strong>\n
- \n
- Brush size: 60\u2013120 px<\/li>\n\n\n\n
- Only for things that can afford to be a bit loose.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
Quick trick we use a lot:<\/p>\n\n\n\n
- \n
- Start with a medium brush.<\/li>\n\n\n\n
- Paint the area.<\/li>\n\n\n\n
- Then step down to a small brush and clean right up to:\n
- \n
- Facial outlines<\/li>\n\n\n\n
- Text blocks<\/li>\n\n\n\n
- Product edges<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
That “big first, small clean\u2011up” approach gives us expressive motion without sacrificing crisp edges.<\/p>\n\n\n\n
We’ve found that overly big brushes on faces or product labels are the fastest way to ruin subject stability. If we’re seeing wobble later, we almost always check: did we paint too far over the important stuff?<\/p>\n\n\n\n
Stability Settings<\/h2>\n\n\n\n
Once the mask is solid, the stability settings are where we turn chaos into something usable.<\/p>\n\n\n\n
PromeAI may adjust labels over time, but the core idea is the same across builds: there’s usually a strength or intensity slider, and a stability or coherence slider controlling how much the original frame holds.<\/p>\n\n\n\n
Our baseline starting point for most shots is:<\/p>\n\n\n\n
- \n
- Motion \/ strength: 0.35\u20130.45<\/li>\n\n\n\n
- Stability \/ coherence: 0.65\u20130.8<\/li>\n\n\n\n
- Duration: 2\u20134 seconds for product and social loops<\/li>\n<\/ul>\n\n\n\n
We nudge from there based on what we’re animating.<\/p>\n\n\n\n

<\/figure>\n<\/figure>\n\n\n\nPreserving faces<\/h3>\n\n\n\n
Faces are brutal. A tiny change in eyes or mouth shape looks “off” instantly.<\/p>\n\n\n\n
Our face\u2011safe recipe:<\/p>\n\n\n\n
- \n
- Don’t paint over the central face at all unless you want expression change.<\/li>\n\n\n\n
- Only paint hair, maybe a little around the shoulders.<\/li>\n\n\n\n
- Settings we like for portrait motion:\n
- \n
- Motion \/ strength: 0.25\u20130.35<\/li>\n\n\n\n
- Stability: 0.8\u20130.9<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
This keeps:<\/p>\n\n\n\n
- \n
- Eye shape consistent<\/li>\n\n\n\n
- Nose and jawline from “breathing”<\/li>\n\n\n\n
- Skin texture from smearing<\/li>\n<\/ul>\n\n\n\n
If we still see facial distortion, we try this sequence:<\/p>\n\n\n\n
- \n
- Reduce motion strength by ~0.05.<\/li>\n\n\n\n
- Increase stability by ~0.1.<\/li>\n\n\n\n
- Tighten the mask so it stops just before the cheeks and jaw.<\/li>\n<\/ol>\n\n\n\n
We also run quick A\/B tests: duplicate the project and try two stability versions side by side. It’s way easier than chasing tiny changes blindly.<\/p>\n\n\n\n
Keeping text sharp<\/h3>\n\n\n\n
Text and logos are even less forgiving than faces. One wobble and the whole design looks cheap.<\/p>\n\n\n\n
Our hard rule: never paint motion directly on text or logos. If we need motion near them:<\/p>\n\n\n\n
- \n
- Leave at least a 5\u201310 px buffer of unpainted space around any text.<\/li>\n\n\n\n
- If the background needs to move, only paint behind the text shape, not across its edges.<\/li>\n<\/ul>\n\n\n\n
Settings that usually keep typography solid:<\/p>\n\n\n\n
- \n
- Motion \/ strength: 0.2\u20130.3<\/li>\n\n\n\n
- Stability: 0.85\u20130.95<\/li>\n<\/ul>\n\n\n\n
If the logo still feels soft:<\/p>\n\n\n\n
- \n
- Drop motion strength even further.<\/li>\n\n\n\n
- Shorten the duration (less time means less chance for drift).<\/li>\n\n\n\n
- Render at a higher resolution and downscale: often the downscale hides micro\u2011wobble.<\/li>\n<\/ul>\n\n\n\n
For critical branding work, we sometimes export two passes:<\/p>\n\n\n\n
- \n
- Animated background.<\/li>\n\n\n\n
- Static logo\/text.<\/li>\n<\/ol>\n\n\n\n
Then we composite them in After Effects, Figma video, or any editor. That way PromeAI handles motion, and we handle pixel\u2011perfect brand control.<\/p>\n\n\n\n
If you want to check the current feature names, PromeAI’s official tutorial section<\/a><\/strong> are handy for the latest updates.<\/p>\n\n\n\n
Common Failure Fixes<\/h2>\n\n\n\n
Let’s be honest: the first run rarely works perfectly. Here are the two failures we keep seeing, and how we fix them.<\/p>\n\n\n\n
Background drift<\/h3>\n\n\n\n
Background drift is that slow, wobbly creep where the whole scene feels like it’s underwater, even though you only meant to move one part.<\/p>\n\n\n\n
Our background drift fix checklist:<\/p>\n\n\n\n
- \n
- Zoom in on the mask.<\/strong>\n
- \n
- Erase any brush strokes that accidentally touch walls, horizon lines, windows, or furniture.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
- Raise stability.<\/strong>\n
- \n
- Add +0.1 to the stability slider.<\/li>\n\n\n\n
- Lower motion strength slightly.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
- Shorten the shot.<\/strong>\n
- \n
- Trim duration from 4\u20135 seconds down to 2\u20133 seconds.<\/li>\n<\/ol>\n<\/li>\n\n\n\n
- Anchor lines:<\/strong>\n
- \n
- Avoid painting over straight lines (table edges, door frames, shelves). Those give away drift fastest.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n\n\n\n
We’ve noticed that even a tiny mask overlap on a straight edge can cause the entire background to “breathe.” Cleaning that overlap usually fixes it more than any setting tweak. For complex backgrounds, the Region Rendering<\/a><\/strong> feature can help isolate specific areas.<\/p>\n\n\n\n
\n ![\"PromeAI](\"https:\/\/www.promeai.pro\/blog\/wp-content\/uploads\/2026\/02\/893d6674-1347-4675-b3ae-2704167ca356-1024x524.png\")
<\/figure>\n<\/figure>\n\n\n\nGeometry warping<\/h3>\n\n\n\n
This is where furniture bends, phones curve, or bottles pulse like jelly. It happens most on:<\/p>\n\n\n\n
- \n
- Hard surfaces<\/li>\n\n\n\n
- Strong perspective lines<\/li>\n\n\n\n
- High\u2011contrast shapes<\/li>\n<\/ul>\n\n\n\n
To reduce geometry warping, we usually:<\/p>\n\n\n\n
- \n
- Keep motion away from rigid shapes.<\/li>\n\n\n\n
- If the product is not supposed to flex, don’t paint it.<\/li>\n\n\n\n
- Use smaller brushes near geometry.\n
- \n
- 5\u201315 px instead of a big soft brush.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Lower motion strength:\n
- \n
- Bring it down to 0.2\u20130.3 for scenes with strong structure.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
For tricky shots, we split the process:<\/p>\n\n\n\n
- \n
- Pass 1: Animate only soft elements (hair, fabric, water) with normal strength.<\/li>\n\n\n\n
- Pass 2: Very subtle motion for reflections or tiny highlights with ultra\u2011low strength.<\/li>\n<\/ol>\n\n\n\n
If we ever need to animate a rigid product (like a phone rotation), we treat it like a stop\u2011motion illusion:<\/p>\n\n\n\n
- \n
- Use local motion control only on edges and reflections.<\/li>\n\n\n\n
- Keep the core shape static.<\/li>\n\n\n\n
- Let the brain fill in the rotation from changing highlight positions.<\/li>\n<\/ul>\n\n\n\n
This trick gives the feeling of movement while keeping the geometry honest. For fixing specific areas that need correction, the Inpainting tool<\/a><\/strong> can be invaluable.<\/p>\n\n\n\n
Use-Case Examples<\/h2>\n\n\n\n
Here’s how we’d actually set this up on real projects.<\/p>\n\n\n\n
\n ![\"PromeAI](\"https:\/\/www.promeai.pro\/blog\/wp-content\/uploads\/2026\/02\/9c752523-ed52-4c2c-8ff7-03b2a1c2de7a-1024x529.png\")
<\/figure>\n<\/figure>\n\n\n\nProduct rotation<\/h3>\n\n\n\n
We did this for a skincare bottle hero shot:<\/p>\n\n\n\n
- \n
- What we masked:<\/strong>\n
- \n
- Just the left and right edges of the bottle and reflection on the table.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Brush sizes:<\/strong>\n
- \n
- 20\u201330 px on the edges<\/li>\n\n\n\n
- 10\u201315 px near the label<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Settings:<\/strong>\n
- \n
- Motion \/ strength: 0.35<\/li>\n\n\n\n
- Stability: 0.75<\/li>\n\n\n\n
- Duration: 3 seconds loop<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
Result:<\/strong> the bottle felt like it gently rotated, but the label text stayed sharp. No weird stretching.<\/p>\n\n\n\n
Hair movement<\/h3>\n\n\n\n
For a portrait where only the model’s hair waves:<\/p>\n\n\n\n
- \n
- What we masked:<\/strong>\n
- \n
- Hair edges, tips, stray strands<\/li>\n\n\n\n
- Zero paint on face, neck, or earrings<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Brush sizes:<\/strong>\n
- \n
- 25\u201340 px for outer hair<\/li>\n\n\n\n
- 10\u201315 px near the cheek and jaw<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Settings for strong subject stability:<\/strong>\n
- \n
- Motion \/ strength: 0.3<\/li>\n\n\n\n
- Stability: 0.85\u20130.9<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
This gave a subtle, looping motion that looked like a fan off\u2011camera. The face stayed locked and natural.<\/p>\n\n\n\n
Water\/smoke effects<\/h3>\n\n\n\n
For environmental motion, waterfalls, rivers, steam, smoke, Motion Brush really shines.<\/p>\n\n\n\n
A recent example: packaging photo with a smoky backdrop.<\/p>\n\n\n\n
- \n
- What we masked:<\/strong>\n
- \n
- Only the smoke plumes behind the product.<\/li>\n\n\n\n
- No paint on the bottle or logo.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Brush sizes:<\/strong>\n
- \n
- 40\u201380 px for big swirls<\/li>\n\n\n\n
- 20\u201330 px for smaller curls near edges<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Settings:<\/strong>\n
- \n
- Motion \/ strength: 0.45<\/li>\n\n\n\n
- Stability: 0.65\u20130.7<\/li>\n\n\n\n
- Duration: 4 seconds<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
Here we want softness and a bit of drift, just not over the subject. That’s where an accurate animation mask matters more than precise geometry.<\/p>\n\n\n\n
