免費線上 DV 轉 OPUS 轉換器

DV is a digital format of magnetic video recording and a type of video compression developed by the major video equipment manufacturers in 1995. The DV format uses an 8-bit digital component video signal with a resolution of 720x576 pixels. Data transfer is made in the form of a DIF-sequence that contains video, audio and subcode data. Date and time are recorded in the service area.

Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end ARM3 processors. Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC, and HE-AAC.
