Soulfun AI Video Generator Tested and Reviewed

Curiosity led me to click “Video Generator” on SoulFun.ai hoping to find something that doesn’t feel like a sanitized version of your imagination.

If you want AI video tools that push past polite boundaries—nudity, risque character interactions, erotic fantasy—this is the kind of feature people are watching closely. I went in expecting some restrictions but hoping enough freedom to make something daring. Here’s what I learned.

Soulfun Video Generator — In-Depth User Guide (3 Workflows)

This tool has three creation modes shown by the tabs at the top: Image to Video, Video Extend, and Text to Video. Each mode uses a large upload area and a Prompt box (up to 800 characters, counter at the bottom-right). I tested it and created this guide for you. Below is a complete walkthrough of every screen and how to get from idea to finished clip.

0) Quick Prep (recommended)

• Assets ready: have your key image(s) or base video(s) handy. Prefer clear, high-resolution sources.
• Prompt plan: write what you want to see (subject, motion, camera, mood, style, length cues).
• Galleries: you can pick from built-in Image Gallery/Video Gallery where noted.

1) Image to Video

Use a single image as the starting frame and let the AI animate it.

What you see

• Key Frame (Upload starting image.)
  A dashed upload panel with a cloud icon. You can Click to upload from your device or select from Image Gallery (blue link). A small (?) icon opens a tooltip for this feature.
• Prompt
  A large text box with the placeholder “Input a prompt to create a dynamic video—unleash your imagination now!” and a live 0/800 character counter.

Step-by-step

1. Upload the Key Frame
   • Click the panel and choose your image, or click Image Gallery to pick an existing asset.
   • Tip: choose a centered, well-lit image; the subject should be distinct from the background.
2. Write your Prompt
   • Describe motion and scene evolution:
     “Slow push-in on the astronaut, visor reflecting a neon city; dust particles drift; subtle head turn; cinematic lighting; shallow depth of field; 8-second loop.”
   • Add camera/mood/style if you care: “handheld feel, soft film grain, warm color grade.”
3. (If shown) Advanced/Help
   • Click the (?) near Key Frame for guidance on image requirements or behavior.
4. Generate
   • Click your platform’s Generate/Create button (usually below the prompt). The system will process and render a short clip based on your key frame and prompt.

Pro tips

• Keep prompts specific but concise (you have 800 chars).
• If the motion looks jittery, reduce conflicting instructions (“fast zoom + slow dolly + pan”).
• To keep identity consistent across attempts, reuse the same key frame and a similar prompt.

2) Video Extend

Continue or “grow” an existing video with new content.

What you see

• Upload Your Video (Video Gallery Only.)
  A dashed upload panel labeled Select from Video Gallery (blue link). This indicates you’ll choose a clip that already exists in your account’s gallery.
• Prompt
  Text box with the placeholder “Extend the sequence — describe anything to generate additional content” and the 0/800 counter.

Step-by-step

1. Choose a Base Clip
   • Click the upload panel, then Video Gallery to pick the clip you want to extend.
2. Describe the Extension in the Prompt
   • Be clear about continuity and timing:
     “Continue after the character closes the door; camera follows down the hallway; flickering lights; suspenseful pacing; add 5–7 more seconds.”
   • Mention look/feel to match the original: “same color grade, same aspect ratio, same character clothing.”
3. Generate
   • Start the render. The model will create the next segment and blend it with your original.

Pro tips

• Reference exact moments to avoid mismatches: “after the car passes the bridge”.
• If the transition is abrupt, try prompts like “smooth cross-fade from the last frame” or “seamless continuation with consistent lighting.”

3) Text to Video

Create a video from scratch with only text. Optionally guide the look.

What you see

• Looks like (Optional) with a (PRO) badge and a + button.
  This lets you attach a reference look (e.g., a style image or a character face) so the video’s visuals follow that appearance. It’s optional and may require a pro plan.
• Prompt
  A large text box with the standard 0/800 counter.

Step-by-step

1. (Optional) Add a “Looks like” Reference
   • Click + and upload a style/character reference if you want consistent identity or art direction (e.g., the same anime style or the same spokesperson face across videos).
2. Write the Prompt
   • Define subject, scene, motion, camera, mood, length cues:
     “Golden retriever runs along a beach at sunrise; gentle slow-motion splashes; low tracking shot; warm, soft light; 10 seconds; uplifting mood.”
3. Generate
   • Start the render to produce a fully AI-synthesized clip.

Pro tips

• If identity drifts, use a clear “Looks like” reference and remind the prompt: “match the attached look.”
• For complex scenes, break them into multiple shorter generations and stitch later.

Prompt Writing Cheatsheet (works in all tabs)

Use this simple structure to stay within 800 characters:

• Subject: who/what is on screen
• Action/Motion: what changes happen
• Camera: “slow dolly in”, “wide aerial”, “handheld close-up”
• Environment/Lighting: “foggy alley, neon rim light”
• Style/Mood: “documentary, cozy, whimsical, cyberpunk”
• Duration cue: “~8 seconds” or “short social clip”
• Continuity (if extending): “same grade/ratio as original”

Example:
“Moody skyline timelapse at night; clouds race past glass towers; stationary wide shot from rooftop; cool blue grade, subtle film grain; occasional airplane streaks; ~8 seconds.”

Managing Outputs

• After generation, your result typically appears in your account’s gallery. From there you can preview, download, rename, or re-run with adjusted prompts or different references.
• Keep a naming convention like project_mode_version (e.g., astro_itv_v3) to track iterations.

Troubleshooting

• Nothing happens after upload: ensure you selected from the correct Image/Video Gallery and filled the Prompt (some modes require it).
• Weird artifacts or warping: simplify the motion request; prefer a cleaner key frame; add “stable composition, natural motion.”
• Identity/style inconsistency: use Looks like (Text to Video) or stick to the same Key Frame (Image to Video); repeat key descriptors.
• Too long or complex: generate in shorter segments and assemble in an editor.
• Prompt too vague: specify camera and motion—these guide the model strongly.

What SoulFun.ai Claims / States Publicly

• On the “Image-to-Video AI” section, SoulFun clearly markets “Bring images of virtual characters to life and taking AI Sexting Into a next level of immersion with our Best NSFW AI Video Generator.” So they explicitly use “NSFW” and “AI Sexting” language.
• Key advertised features are:
  • 96%+ facial consistency with ArcFace; attribute consistency 97% for stable props/facial details.
  • 1080p @ 24fps output. Full HD video quality claimed.
  • Videos can be up to 20 seconds in length—“continuous video—no stitching, no pauses.”
  • Smooth, realistic motions, and “complex actions & emotions” (e.g. subtle smile, dance) are mentioned.
• The workflow as described: from the character gallery, pick or upload a photo of your virtual character, then use “Generate Videos” with a prompt.
• There is a “Video Gallery” where already-generated videos are shown. These expire in 30 days, so you have to save your work.

What Users / Community Reports Say

• On Reddit, someone wrote that SoulGen’s Video Generator (not SoulFun, but people sometimes mix them up) can create NSFW AI videos “without restrictions.” The caveat: the output might not always follow exactly what the prompt said.
• From what people report, there is sometimes mismatch between what is asked (prompt) and what is delivered: some desired sexual / erotic details can be softened or ignored.

What Is Unclear / Possible Restrictions

• While SoulFun uses “NSFW” and “AI sexting” in marketing, there is no well-documented public statement about exactly how explicit allowed content is. For example, do they allow full nudity, sexual acts, fetish-type content? No official detailed policy is visible.
• The content policy page of SoulFun doesn’t clearly list allowed vs disallowed erotic content in the video generator section as far as I saw. It’s vague.
• Since there is a “30 day expiration” for videos, it suggests content retention is limited, possibly due to legal or moderation concerns.

My Personal Opinion: What It Feels Like in Practice

If I were you wanting to use this for uncensored video generation, here’s how I see it: SoulFun Video Generator does allow NSFW/erotic video creation (based on what they claim).

Quality specifications (1080p, 24fps, facial consistency) are above average, which is promising. However, I believe there will be some filters in place—particularly for edgy, explicit prompts.

You’ll probably get more success with suggestive, sensual content (erotic fashion, mild nudity, intimate settings) than with hardcore or very explicit sexual acts. It seems built for immersion and flirting, not full graphic adult filmmaking.

Emotionally, this feels like a tool that wants to let you sketch your fantasy, but might not hand you the full canvas unless you push carefully.

Tips If You Decide to Try It

• Use a high quality photo of your character or person to start with (lighting, clear facial features, relaxed pose). That increases the chance facial consistency will hold.
• Phrase your prompt so it uses adult / NSFW cues but not necessarily ultra-graphic language. For example: “intimate bedroom lighting, soft skin exposure, sensual pose” rather than explicit actions. See what restrictions trigger.
• Try shorter clips first (20 seconds is long enough) so you don’t waste credits or run into render errors.
• Save your generated videos quickly (before the 30-day expiry) so you’re not scrambling.
• Test in free mode (if available) or small subscription to see how forgiving the system is. If the system starts censoring or distorting when you get bold, you know where their line is.

Conclusion: Would I Try It?

Yes—I would try SoulFun’s Video Generator if I were interested in NSFW videos. The features sound tempting, more so than many tools that talk about NSFW but don’t deliver video, or deliver only images.

But I go in expecting boundaries. If you go in with open eyes, try with gentler erotic prompts, and test how far you can push before censorship or distortion kicks in, you might land something impressive.
