In order to support live view, camera manufacturers had to build sensors capable of transferring image data at high rate. DSLRs also need to have a powerful image processing chip to do real time JPEG creation and noise processing at high frame rates for very high pixel density (e.g. 15 or 21MP) images. Writing firmware for the same processing chip to do video compression is incremental hardware and software development effort, especially for companies like Canon that already has both HW and SW for real time HD video compression.</p></blockquote><p></p>
