VFX significa efectos visuales, las imágenes que se crean o modifican después de rodar una escena. Abarca desde un cielo cambiado hasta una criatura totalmente digital, y aparece en casi todas las películas, series y anuncios que ves.
For most of its history, VFX meant a green screen, expensive software, and a team of specialists. That is changing fast, because AI can now do a large part of the same work from a single video upload.
This guide explains what VFX is, how it differs from CGI and SFX, the main types you will run into, and how AI video effects let you do it without a green screen setup or proper studio.
Conclusiones clave
- Los VFX (efectos visuales) son imágenes creadas o modificadas en posproducción, después de haber grabado el metraje.
- CGI is a subset of VFX (imagery made entirely by computer), and SFX is practical effects done live on set.
- The common types of VFX are compositing, CGI, motion capture, matte painting, and rotoscoping.
- Los VFX tradicionales necesitan una pantalla verde, un compositor y software como Nuke o After Effects.
- Los efectos de vídeo con IA se encargan de cambios de fondo, reiluminación y ediciones con máscara a partir de una sola subida, sin necesidad de croma ni experiencia en edición.
What is VFX?
VFX stands for visual effects. It is the process of creating or changing imagery outside of a live-action shot, then blending it into the footage so it looks real.
VFX exists because some shots are too expensive, too dangerous, or simply impossible to capture in camera. A destroyed city, a distant planet, or a clean background behind a messy room are all easier to build in post-production than on set.
The key detail is timing: VFX happens after filming, not during it. That is what separates it from practical effects, and it is also why AI has been able to take so much of the work over.
VFX vs CGI vs SFX
Estos tres términos se usan indistintamente, pero significan cosas distintas. Conocer la diferencia hace mucho más fácil entender qué hace realmente una herramienta de efectos de vídeo con IA.
VFX is the broad umbrella. It covers any imagery created or manipulated in post-production, including compositing, matte painting, motion tracking, and CGI.
CGI, or computer-generated imagery, is a subset of VFX. It refers to imagery made entirely by a computer, like a 3D creature or a fully digital environment. All CGI is VFX, but not all VFX is CGI.
SFX, o efectos especiales, son efectos prácticos logrados en directo en el set. Las explosiones controladas, la lluvia falsa, las prótesis y los animatronics son todos SFX, porque ocurren delante de la cámara en lugar de en posproducción.
The main types of VFX
Most visual effects fall into a handful of categories. AI video effects map onto the same ideas, so it helps to know the traditional versions first.
Compositing layers combinan imágenes separadas en un solo fotograma. La forma más común es el trabajo con croma, donde se graba a un sujeto sobre un fondo verde y luego se incrusta un nuevo fondo detrás de él.
CGI builds elements from scratch on a computer, from characters to entire worlds. Matte painting extends a set with a painted or digital landscape, and motion tracking locks CGI elements onto moving footage so they stay in place.
Motion capture records an actor's movement and maps it onto a digital character. Rotoscoping is the manual work of tracing a subject frame by frame to separate it from its background.
How traditional VFX works, and why it is hard
The classic VFX pipeline is powerful, but it is slow and expensive. That is the gap AI video effects are built to close.
A typical shot needs a green screen studio, controlled lighting, and a clean plate. After filming, a compositor keys out the background, cleans the edges by hand, and matches the lighting so the new scene looks believable.
That work runs through software like Nuke or Adobe After Effects, often on a render farm, and it can take days for a few seconds of footage. It also demands real training, which puts traditional VFX out of reach for most solo creators and small teams.
Cómo la IA cambió los VFX
AI video effects skip most of that pipeline. Instead of keying, rotoscoping, and compositing by hand, an AI model reads your footage and does the separation for you.
Modern video models are trained to isolate a subject, rebuild the lighting across a whole frame, and edit specific regions without a green screen or manual cutout. You upload a normal clip, describe the result you want, and the model generates it in minutes.
This is even handier if you're already producing video content on an Generador de vídeo con IA instead of traditional filming.
Activado OpenArt VFX, this runs on Beeble's SwitchX, un modelo de vídeo a vídeo pensado para un aislamiento limpio del sujeto, reiluminación de fotograma completo y ediciones de zonas enmascaradas. Usa tu material original como guía directa, así el movimiento y la identidad de tu sujeto se mantienen intactos en lugar de desviarse de un fotograma a otro.
The three AI VFX modes, mapped to classic VFX
OpenArt VFX gives you three modes from a single upload. Each one is the AI version of a traditional visual effects technique.
Swap the background without a green screen
Video background changer es la versión con IA de la composición y el chroma key. Aísla tu sujeto y sustituye la escena de fondo, sin croma y sin recortes manuales. Eliges un preajuste, subes una imagen o generas un nuevo entorno con IA.
Reiluminar toda la escena
Reiluminación de vídeo con IA mode does the job of a lighting setup and a color grade at once. It rebuilds the lighting, color, and mood across the full frame instead of adding a flat filter, so shadows and highlights look real. Your performance and camera motion stay exactly as shot.
Protect a masked region and transform the rest
Inpainting mode is the AI version of rotoscoping and masking. You paint a mask over the part of the frame you want to keep, like a face or a product, and that region stays exactly as shot while everything outside the mask transforms. You only mask the first frame, and the model tracks the protected region across every frame after it.

Upload your video.
Drop in any MP4 or MOV clip. AI video effects work on footage from any room, with no green screen or studio setup.
Pick your mode.
Choose Background, Relight, or Inpainting. Direct it with a preset, a reference image, or a text prompt.
Generate and compare.
SwitchX renders your clip in a few minutes. Preview the result in a side-by-side view, refine if needed, and download an MP4.
Quién usa los efectos de vídeo con IA
El atractivo es amplio, porque la barrera de entrada ahora es muy baja. Los creadores de redes sociales cambian fondos o reiluminan metraje casero para crear un estilo propio sin un plató.
Cineastas y directores obtienen composición y reiluminación sin Nuke ni After Effects, convirtiendo las regrabaciones en una máscara y un prompt. Los equipos de marca y marketing graban una vez y luego aplican distintos fondos y ambientes por campaña, así una sola sesión se convierte en toda una biblioteca de contenido.
The bottom line
El VFX es el arte de crear y modificar imágenes después de rodar una toma, y durante décadas requirió un estudio, un compositor y software especializado. Los efectos de vídeo con IA mantienen el mismo control eliminando el croma, el pipeline y la curva de aprendizaje.
If you want to try it on footage you already have, OpenArt VFX cambia fondos, reilumina y aplica ediciones con máscara desde una sola imagen, gracias al modelo SwitchX de Beeble.
Frequently asked questions
What does VFX stand for?
VFX stands for visual effects. It is the imagery that is created or changed after a scene is filmed, then blended into the footage so it looks like part of the original shot.
Is VFX the same as CGI?
No. CGI (computer-generated imagery) is one type of VFX, made entirely by a computer. VFX is the wider category that also includes compositing, matte painting, and motion tracking, so all CGI is VFX but not all VFX is CGI.
¿Cuál es la diferencia entre VFX y SFX?
VFX is done in post-production, after filming. SFX (special effects) are practical effects created live on set, like explosions, fake rain, or prosthetics.
¿Se pueden hacer VFX sin croma?
Yes. AI video effects isolate your subject and replace or relight the scene without a green screen or manual cutout. OpenArt VFX does background swaps, relighting, and masked edits from a single upload.
Do you need experience to make VFX?
Ya no. Los modos de fondo y reiluminación están pensados para usarse con un solo clic mediante un preset o una referencia. Las ediciones de regiones enmascaradas dan mejores resultados con un enmascarado cuidadoso, pero no se necesita software de composición ni formación en posproducción.
¿Qué software necesitas para los VFX?
Traditional VFX runs on tools like Nuke or Adobe After Effects, often with a render farm. AI video effects run in the browser, so you upload a clip, pick a mode, and download the result with nothing to install.
