How JPEG to M4V Conversion Works
JPEG is an image format: it uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. M4V is a video format that stores data in the M4V format. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date is preserved where the target format supports it; features the target format cannot represent are dropped. Converting between these two formats is common when the source application does not support M4V natively or when the target platform only accepts M4V. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
