You might be confused with the 30min recording time limitation, another annoying software-based limitation many cameras have. Starting from 30 minutes a camera was considered as a video camera and subject to an extra levy—this was scrapped not so long ago, and camera makers are starting to remove the limitation on their newer models. Having clean HDMI or not is just a matter of market segmentation, it used to be a premium feature. Canon is really bad in this regards—many camera’s don’t have clean HDMI and/or shut off the HDMI output after 30 minutes. Luckily CHDK allows to add clean HDMI and disable power off to the Canon M3 and a number of other cameras, worked like a charm for me. https://chdk.fandom.com/wiki/CHDK https://chdk.fandom.com/wiki/CHDK https://chdk.setepontos.com/index.php?topic=13489.0 https://chdk.setepontos.com/index.php?topic=13489.0
