1. Chroma Subsampling (YUV 4:2:0)
Standard video codecs (H.264, HEVC/H.265, ProRes, AV1) compress video using YUV 4:2:0 subsampling, where each 2×2 pixel quad shares one chrominance (color) sample. An odd pixel width or height creates a half-block, causing encoder crashes, rendering failures, or green artifact lines on exports.
2. Macroblock Alignment (mod 2 / mod 8 / mod 16)
Hardware decoders and encoders process video in 16×16 or 8×8 DCT blocks. Even dimensions (mod 2) are mandatory for export. Aligning with mod 8 (AI generation) or mod 16 (H.264) guarantees maximum compression efficiency.
