Question 1

What is YUV color space?

Accepted Answer

YUV is a color encoding used in video and broadcasting, separating luma (Y) from chroma (U and V). It saves bandwidth compared to RGB by encoding brightness at full resolution and color at lower resolution.

Question 2

What's the difference between BT.601, BT.709 and BT.2020?

Accepted Answer

BT.601 is for standard-definition TV (SD), BT.709 is for HDTV, and BT.2020 is for 4K/UHD. Each defines different coefficients for converting between RGB and YUV based on the target gamut.

Question 3

Is this converter private?

Accepted Answer

Yes. All conversion runs in your browser. No pixel data, no values are uploaded to any server.

Question 4

Can I use this for FFmpeg or ffmpeg-python?

Accepted Answer

Yes. This tool uses the same BT.601/BT.709 conversion matrices that FFmpeg uses internally, so you can verify your pipeline values or sanity-check pixel math.
