What Is This Tool?
This resource provides free sample files in the UYVY format, a packed YUV 4:2:2 image representation. These samples help developers and users test video capture, processing, and encoding scenarios where UYVY is commonly used.
How to Use This Tool?
-
Download UYVY sample files to evaluate video capture and processing pipelines
-
Use samples for testing GPU/ASIC-accelerated video effects and framebuffer workflows
-
Apply files as input for encoders, decoders, and video APIs before compression
-
Experiment with offline transcoding and raw video frame manipulation
Key Features
-
Uncompressed 8-bit Y'CbCr 4:2:2 packed pixel format
-
Efficient pixel storage in U0 Y0 V0 Y1 order for pairs of pixels
-
Preserves full horizontal luminance detail for sharp image quality
-
Supported by many video capture devices, APIs, and libraries
-
Lower memory and bandwidth usage compared to full RGB color
Examples
-
Capturing live video input using UYVY frames from a camera or capture card
-
Processing frames in real-time with hardware acceleration preserving luminance data
-
Using UYVY format in FFmpeg or V4L2 applications prior to encoding
-
Transcoding stored raw UYVY video frames for offline editing
Common Use Cases
-
Live video capture and streaming with multimedia pipelines
-
Intermediate framebuffer format in hardware-accelerated video processing
-
Input/output format for video API workflows and encoding tools
-
Storage of raw video frames for offline processing and analysis
Tips & Best Practices
-
Remember that UYVY uses 4:2:2 chroma subsampling, which reduces horizontal color resolution
-
Convert UYVY files to RGB format when required for display or compatibility with image tools
-
Be cautious of the specific component byte order to avoid interoperability issues
-
Use these samples to validate hardware and software that support UYVY format handling
Limitations
-
Reduced horizontal chroma resolution due to 4:2:2 subsampling may impact color accuracy
-
Uncompressed nature results in large frame sizes compared to compressed video codecs
-
Requires conversion to RGB for display and many image processing applications
-
Component ordering differs from similar formats like YUY2, which can cause compatibility errors
Frequently Asked Questions
-
What is UYVY format used for?
-
UYVY is mainly used for video capture, intermediate video processing, and as an input/output format for video APIs and encoders before compression.
-
Why does UYVY have lower memory usage than RGB?
-
Because UYVY employs 4:2:2 chroma subsampling, it reduces the color resolution horizontally, lowering memory and bandwidth requirements compared to full 4:4:4 RGB.
-
Do UYVY files require conversion for display?
-
Yes, UYVY files generally need to be converted to RGB format for display or use in many image-processing tools.
Key Terminology

-
Chroma Subsampling
-
Technique reducing color detail in images by sampling chrominance components at lower resolution than luminance.
-
Framebuffer
-
A memory buffer containing pixel data used in video processing and display pipelines.
