4K video files (often in MKV or MP4 containers) are already heavily compressed codecs (like H.265/HEVC). Compressing an already

Historically, these platforms had strict file size limits for uploads (e.g., a maximum of 50MB or 100MB per post). To bypass these restrictions, archivers split large files into manageable chunks. Even with a 4K video file that could be 80GB, splitting it allows for easier indexing and propagation across servers. LAFBD-41-4K.part36.rar
