This conversion typically involves decoding YUV pixel data, converting color and resolution to RGB, embedding images into an eBook layout or XHTML, and packaging as an AZW3-compliant EPUB/KF8 file suitable for Kindle devices and apps.

Keep individual image frames under ~5–10 MB before embedding to ensure responsive rendering on most Kindle devices and prevent slow open times.
Preserve quality by converting YUV to full-range RGB with correct color matrix (e.g., BT.601 vs BT.709) and avoid unnecessary recompression—use PNG for lossless needs.
