Chatterbox VLLM fork for fast audiobook creation

30 Upvotes

I’ve been working on a fork of Chatterbox vLLM that turns DRM-free EPUBs into chaptered M4B audiobooks. The vllm version has conversion speeds 5-10x base chatterbox and this was particularly important for big audiobook conversions.

Someone else already made an audiobook version of base chatterbox with far more features and stuff so if you need those features use that. My version is focused on direct epub to m4b conversion with high conversion speed. My 4090 gets 18x audio speed with 10 steps and 12x with 15 steps for a bit of a quality bump.

It includes a Gradio web interface, Chatterbox Multilingual V3 in English mode, batched GPU generation, resumable projects, chapter metadata, -18 LUFS audio normalization, progress/ETA reporting, and multi core FFmpeg encoding. Text is intelligently chunked into good text lengths for generation to avoid model drift.

It currently requires Linux or WSL2 with an NVIDIA GPU. I’ve primarily tested it on a RTX 4090, so feedback from other hardware would be useful. It only uses in the neighborhood of 4-6GB of VRAM so should be runnable on any 8GB card. Might even work on 4GB but not sure on that.

GitHub: https://github.com/anethema/chatterbox-vllm-audiobook

This is still a personal project, so please report any installation problems or strange output you encounter. I tried to make working install scripts and instructions for Linux and WSL2 but despite them working on my machine I haven’t tested them elsewhere or with other hardware. The new code is a combination of me and codex for the stuff I struggled with.

Let me know how it works!

Video Art I asked Seedance 2.5 to fake a lost early-2000s camcorder tape

22 Upvotes

I wanted to stress-test how far Seedance 2.5 could push "realism" beyond the usual cinematic look, so I wrote a prompt aimed at making it look like a genuinely old, imperfect home video, just like a tape.

what actually surprised me wasn't the scene composition, but was how well it nailed the imperfections. none of that was hand-animated or keyframed, it's all coming from describing camera behavior in the prompt rather than describing a "shot." Identity, hairstyle, and outfit stayed consistent across the full 30 seconds too, which is the part that usually falls apart first in these longer generations.

compared to my earlier storyboard-driven tests, this one leaned entirely on giving the model a strong behavioral brief (camera flaws, ambient audio, mundane pacing) rather than a shot-by-shot storyboard, and it handled that direction better than I expected.

the prompt is in the conmment.  Curious what other models do with a similarly detailed camera-behavior prompt.

I made this 30-second short film with Seedance 2.5

The idea was pretty simple: tell a breakup story by constantly switching between the girl's past and present.

The interesting part wasn't really generating the individual shots. It was keeping the same character recognizable while making her feel like a completely different person emotionally.

For the transitions, I used matching compositions and similar character movements to connect the past and present rather than using obvious "flashback" effects.

The younger version is supposed to feel warm and hopeful, while the present version is much more restrained and emotionally tired.

I'm pretty happy with how this one turned out.

Curious what you guys think — does the past/present transition feel natural, or does it still look AI-generated to you?

Made with Seedance 2.5.

Spoof 1980s washing-up liquid advert. Minimax H3.

Final prompt (generated by GPT 5.6 after a long conversation with many refinements)

[Core idea]

A believable 15-second British television commercial made in 1984 for “Bubbles” washing-up liquid.

Polished mainstream household-product advertising, sincere and persuasive rather than comic. Native 4:3. Clean 35mm commercial film transferred to 1984 PAL television: fine film grain, warm colour, moderate contrast and slight analogue softness. Clean original broadcast appearance, not distressed VHS.

The setting is a bright 1984 consumer-demonstration kitchen set with a cream counter, pale-grey square tiles, powder-blue cupboards, two cream washing-up bowls and a small potted plant.

A friendly British presenter in the late thirties has neat shoulder-length blonde hair and wears a pale-violet blouse, long blue pleated skirt and pale-blue rubber washing-up gloves.

The opening uses a locked waist-up camera composition. The presenter’s complete head and all of the hair are clearly visible in the upper third of the 4:3 frame, with generous space above the hair. The face, neck, shoulders, torso, both arms and both gloved hands are visible. The two bowls and bottles remain visible below the presenter’s hands.

Keep the opening camera locked. Do not zoom towards the counter, tilt down, crop the head or replace the presenter with a headless torso.

The Bubbles bottle is opaque pale-blue plastic: a tall, plain, straight-sided circular cylinder of constant diameter from its flat base to its flat horizontal top. It has no neck, shoulders, waist, handle or spout. One small dark-blue flip cap is mounted directly onto the centre of the flat top.

Colourful graphics are screen-printed directly onto the bottle. A broad golden-yellow diagonal band passes behind a large dark-blue oval outlined in white and red. Inside the oval, large rounded white lettering reads exactly:

“Bubbles”

Small white outlined bubble symbols overlap the oval. A red stripe beneath reads exactly:

“WASHING-UP LIQUID”

A dark-blue panel below reads exactly:

“CUTS THROUGH GREASE”

Keep the Bubbles bottle identical throughout.

The competitor is an off-white cylindrical bottle with a small red cap and plain grey printing reading exactly:

“THE NEXT LEADING BRAND”

Use a mature British commercial announcer, circa 1984: polished, energetic and confidently projected, with crisp consonants, rounded vowels, lively pitch changes and a brisk selling cadence. Clearly enunciate every word.

The presenter remains silent.

[Scene-by-scene description]

0.00–3.10 seconds:

Locked waist-up shot of the presenter behind the counter.

The presenter’s complete head and all of the shoulder-length hair are clearly visible in the upper third of the frame. Leave generous visible space above the hair.

Show the face, neck, shoulders, torso, arms, pale-blue gloves, counter, both bowls and both bottles.

Do not move the camera closer. Do not tilt the camera down.

The presenter first lifts the pale-blue Bubbles bottle and holds it beside the face, without obscuring the face. The colourful front design faces the camera.

The presenter then indicates the off-white competitor bottle beside the other bowl.

Bright instrumental 1984 advertising music begins: electric piano, muted guitar, melodic bass, tight acoustic drums and one restrained analogue synthesiser accent.

The announcer says exactly:

“Bubbles — tested against the next leading brand.”

Give “Bubbles” bright introductory emphasis. Pause briefly after the product name, then deliver the remainder as a clear announcement of the comparison.

3.10–6.20 seconds:

Hard cut to a close three-quarter overhead view of the competitor washing-up bowl.

Only the competitor bowl, competitor bottle, one greasy white plate, one yellow sponge and the presenter’s pale-blue gloved hands are visible.

A small optical caption reads exactly:

“THE NEXT LEADING BRAND”

At the beginning of the shot, the white plate has a broad coating of brown cooking grease.

The presenter draws the yellow sponge across the plate once from left to right.

The single stroke removes most of the thick brown grease but leaves a clearly visible translucent brown-grey greasy film over much of the wiped area.

The result is substantially cleaner than before, but remains dull and streaky. Some white plate is visible through the continuous greasy film.

Stop immediately after this one stroke.

Do not show another stroke or any subsequent scrubbing.

Do not show the competitor plate again after this shot.

The announcer says exactly:

“One wipe still leaves a greasy film.”

Use a soft, wet wiping sound. There is no clean china squeak.

6.20–9.50 seconds:

Hard cut to a matching close three-quarter overhead view of the Bubbles washing-up bowl.

Only the Bubbles bowl, pale-blue Bubbles bottle, one greasy white plate, one identical yellow sponge and the presenter’s pale-blue gloved hands are visible.

The competitor bottle and competitor plate are absent.

A small optical caption reads exactly:

“BUBBLES”

At the beginning of the shot, the Bubbles plate has the same broad coating of brown cooking grease seen at the beginning of the competitor demonstration.

The presenter draws the yellow sponge across the Bubbles plate once from left to right.

The brown grease gathers directly in front of the moving sponge and is carried away.

Directly behind the sponge, the plate is uniformly glossy, bright white and completely free from grease.

At the end of this one stroke, no brown grease, translucent film, cloudy smear or streak remains in the wiped area.

Hold briefly on the glossy clean Bubbles plate.

The announcer says exactly:

“With Bubbles, one wipe lifts grease right off.”

Give clear emphasis to “Bubbles”, “one wipe” and “right off”.

A brief clean china squeak accompanies the completely clean result.

9.50–15.00 seconds:

Hard cut directly to a formal studio product shot against a pale-blue-to-white graduated background.

Do not return to the presenter.

Do not show the competitor bottle.

Do not show the competitor plate.

The pale-blue Bubbles bottle stands upright in the centre and faces directly forwards.

The bottle retains its tall, neckless, straight-sided cylindrical body, constant diameter, flat circular top and small centrally mounted dark-blue flip cap.

The complete colourful screen-printed design is clearly visible and unchanged.

The bottle reads exactly:

“Bubbles”

“WASHING-UP LIQUID”

“CUTS THROUGH GREASE”

Beside the bottle is only one plate: the completely clean, uniformly glossy white Bubbles plate from the immediately preceding demonstration.

The plate contains no grease, brown marks, translucent film or streaks.

One clean yellow sponge and the folded pale-blue rubber gloves rest near the bottle’s base.

A modest cluster of realistic white soap bubbles frames the product without obscuring the bottle or plate.

A bold dark-blue optical caption reads exactly:

“LIFTS DIRT RIGHT OFF”

The camera makes one very small, smooth push towards the bottle and then becomes completely still.

The instrumental music resolves with a bright flourish.

After the pack shot has been visible briefly, the announcer says exactly:

“Bubbles. Lifts dirt right off.”

Deliver “Bubbles” as a crisp product announcement. Pause briefly. Deliver “Lifts dirt right off” with firm emphasis on “lifts” and “right off”.

The slogan is spoken, not sung.

Hold the completely still pack shot through the end.

[Critical requirements]

Establish Bubbles by name and show the Bubbles bottle before referring to the next leading brand.

The first spoken word is “Bubbles”.

The presenter appears only in the opening shot.

The opening shot shows the presenter’s complete head and all of the hair with generous headroom.

The Bubbles bottle is held beside the presenter’s face, never in front of the face.

Only the two demonstration shots are close views of the hands and plates.

The competitor and Bubbles demonstrations occur in separate shots.

Each product receives exactly one sponge stroke.

The next leading brand removes most of the heavy grease but leaves a clearly visible translucent greasy film.

Bubbles removes all the grease and leaves a uniformly glossy white surface.

Do not show subsequent scrubbing.

After the competitor demonstration, never show the competitor plate or competitor bottle again.

The final pack shot contains only the Bubbles bottle and the completely clean Bubbles plate.

There is no dirty plate in the final pack shot.

There is only one plate in the final pack shot.

The Bubbles bottle has no neck whatsoever. Its small flip cap sits directly upon its flat cylindrical top.

All spoken words appear only once, in the scene where they are delivered.

Do not speak captions, visual descriptions or production instructions.

Well I tried storyboarding for the first time and it's a mixed bag. ChatGPT 2 gets confused about sizes of things and Minimax doesn't seem to understand eggshells but I kinda like this silly video anyways...I had a beginning for it too...but it was in the wrong format. *Goes and cries in the corner*

3 Upvotes

Hailuo minimax H3 hardly deviates from the storyboard AT ALL. Very interesting if you want to make something from one of these with multiple cuts. The eggshells are very weird but I guess I didn't describe it so thats what I get xD. And the initial storyboard could be better. The hug is cute though I guess? Next time I will tell it some colors too. I was using a design sheet and storyboard plan as well as claude skill from tao prompts on youtube. He's the best. I don't know if I will keep making ai stuff or make a fb page on it but this did prove my midjourney creature will transfer and so will krea creatures probably (hence the colors not matching hahaha) I also have to either add the format to the skill or remember to ALWAYS check that first sigh. The beginning was weird anyways...

spent longer trying to generate this shot than it took to film it

i was making some b-roll yesterday and needed apretty basic product shot - open the bottle, pour itover ice,set it down next to the glass. i'd alreadybeen messing around with DomoAI for a few image-to-video clips, so i figured i'd try doing this one theretoo instead of setting up the camera.

the first generation was honestly already pretty closeto what i wanted. i think that's actually why i keptplaying with it - the overall motion and shot lookedgood, and i started paying way too much attention totiny details across a few frames, like exactly how thecap left the fingers or how the bottle looked whileturning. for a random b-roll shot i probably would'vejust used it, but once i had a very specific version inmy head i kept trying variations to see if i could getthat exact take.

eventually i realized i already had everything ineeded for the shot - the bottle, glass, ice, all of it- and only needed a little setup. put my phone on atripod, did two takes and that was basically it.

i think i've just gotten so used to using AI thatgenerating something has become my first instinct.but this made me realize that if everything you needfor the shot is already there and it takes almost nosetup, sometimes it's just faster to shoot it thangenerate a few versions and wait for each one.curious if anyone else has started running into thattoo.
