Smooth Transcoding & Playback

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.

FAQ

Playing videos using on-the-fly transcoding requires a GPU. If your NAS does not have a GPU this function will be unavailable.

Media Viewer only supports videos up to 1080p when using on-the-fly transcoding. Videos with resolutions higher than 4K should first be manually transcoded to 1080p for on-the-fly transcoding.

The video may have the rotate attribute. You can check for this attribute in the EXIF of the video file. On-the-fly transcoding forces the video to rotate and remove the rotate attribute, which causes high CPU usage, before it processes on-the-fly transcoding. You should manually transcode videos which have the rotate attribute.
