Easily transcode and play multimedia files stored on your QNAP NAS—CAYIN Media Viewer enhances your viewing experience!

Enhance multimedia playback on your QNAP NAS

CAYIN Media Viewer supports a wide range of video and audio codecs. Its powerful transcoding engine converts various multimedia files on your NAS to MP4 (H.264 / H.265) format, delivering a smooth playback experience with resolutions up to 1080p.

HEIF/HEIC Photo and HEVC Video Format Support

HEIF/HEIC and HEVC are the most recommended formats for mobile devices, as they offer higher compression rates than JPEG and H.264 which significantly saves storage space. After uploading HEIF/HEIC photos and HEVC videos from your phone to a QNAP NAS, you can easily play them in File Station, QuMagie AI Photo Album, or Video Station by transcoding them to MP4 (H.264 / H.265) format with CAYIN Media Viewer.
