Help Guide Find How to Use Interchangeable Lens Digital Camera ILCE-7/ILCE-7R AVCHD format The AVCHD format was developed for high-definition digital video cameras when recording an HD (HighDefinition) signal using high-efficiency compression coding technology. The MPEG-4 AVC/H.264 format is used to compress video data, and the Dolby Digital or Linear PCM system is used to compress audio data. The MPEG-4 AVC/H.264 format is capable of compressing images at higher efficiency than that of the conventional image compressing format. As the AVCHD format uses compression coding technology, the picture may be unstable in scenes where the screen, angle of view, or brightness, etc. change drastically, but this is not a malfunction.
