ASCII Glyph Video Renderer
ASCII Glyph Video Renderer is a paid API for AI agents from eg-pie-zero-ascii-glyph-video.hf.space, paid per call via MPP, $0.30/call, status unknown (last checked 2026-09-15).
Converts a source MP4 into a Speakeasy-style ASCII glyph animation where each frame cell is rendered as a single monospace character with luminance-driven opacity, returning a signed download URL for the output MP4.

How this service works
Fetches the source mp4 from `url`, decodes each frame, and re-emits an mp4 where every visible cell is a single monospace glyph with alpha proportional to source luminance. Returns a signed 24h download URL for the composited mp4.
Output
Returns a JSON object containing a signed 24-hour download URL for the composited ASCII glyph MP4, a unique glyphId, output video dimensions (width, height), frame count, fps, duration in seconds, file size in bytes, render time in milliseconds, and a tokenExpiresAt timestamp indicating when the download link expires.
Example use cases
Hero loop for product launch
“Grab the video at https://cdn.mycompany.com/launch-hero.mp4 and turn it into an ASCII glyph animation using the '@' character, dark background #0a0a0c, glyph color #e0e0e0, cell size 8 — keep the full clip and send me the download link when it's ready.”
Presentation stinger with glyph aesthetic
“Convert the mp4 at https://assets.studio.io/stinger-intro.mp4 into a Speakeasy-style ASCII animation — use the '#' character, background color #111114, glyph color #c8c8c8, cell size 6, and trim it to just the first 10 seconds so it works as a deck opener. Give me the signed download URL.”
Brand reel ASCII overlay effect
“I've got a brand reel at https://media.brand.co/reel-2024.mp4 — render it as an ASCII glyph animation with the '·' character, a near-black background (#080810), light glyph color #f0f0f0, and cell size 5. I want the whole 45-second clip preserved frame-for-frame. Drop the download link once it's done.”

Endpoint
POSThttps://eg-pie-zero-ascii-glyph-video.hf.space/v1/ascii-glyph-videoWhen to prefer
Choose this endpoint when you need to stylize a short-form video (up to 60 seconds) as a monospace ASCII glyph animation — especially for brand videos, hero loops, presentation stingers, or deck backdrops with a Zero/Speakeasy aesthetic. It is the right choice when the output must remain a properly encoded MP4 (not a GIF or image sequence) and when luminance-driven character opacity is the desired visual style. Prefer this over image-based ASCII converters when motion fidelity from the source footage must be preserved frame-by-frame.
Side effects
- Source URL is not publicly accessible or returns non-200 — server cannot fetch the MP4
- Source file exceeds 100 MB — rejected before rendering begins
- Source duration exceeds 60 seconds server-side cap — trimmed or rejected
- Invalid hex color format for fg/bg — parameter validation error
- Cell size or maxWidth outside allowed range — 400 validation error
- Download URL expired after 24 hours — token no longer valid for retrieval
- Source URL points to a non-MP4 format — decoding failure
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| bg | string | Background colour as `#hex` or `r,g,b`, or the literal `transparent` (output stays yuv420p but glyph opacity is premultiplied against black). |
| fg | string | Glyph colour as `#hex` or `r,g,b`. |
| fps | — | Override output frame rate. Omit or null to keep the source fps. |
| urlrequired | string | Publicly fetchable http(s) URL to the source mp4. Max 100 MB. |
| cell | integer | Pixels per glyph cell. Smaller = denser detail, more expensive to render. |
| glyph | string | The single character painted in each cell. Default `0` matches the Zero brand. |
| maxWidth | integer | Downscale the source to this width if larger (aspect preserved). Snaps to a whole-cell multiple. |
| threshold | number | Skip any cell whose luminance is below this. Lower = more dense output. |
| maxDurationSec | number | Trim the source to this duration (from the beginning). Hard-capped at 60 s server-side. |
