The transcoding feature converts a video stream into different codecs, resolutions, and bitrates for playback on different devices and under different network conditions. For more information, see Transcoding.
VOD supports the following transcoding formats:
|Input||Container format||WMV, RM, MOV, MPEG, MP4, 3GP, FLV, AVI, RMVB, TS, ASF, MPG, WebM, MKV, M3U8, WM, ASX, RAM, MPE, VOB, DAT, MP4V, M4V, F4V, MXF, QT, Ogg|
|Video codec||AV1, AVS2, H.264/AVC, H.263, H.263+, H.265, MPEG-1, MPEG-2, MPEG-4, MJPEG, VP8, VP9, QuickTime, RealVideo, Windows Media Video|
|Audio codec||AAC, ADPCM, AMR, DSD, MP1, MP2, MP3, PCM, RealAudio, Windows Media Audio, Vorbis|
|Output||Container format||Video: FLV, MP4, HLS (M3U8 + TS), MXF|
|Audio: MP3, MP4, Ogg, FLAC, M4A|
|Image: GIF, WebP|
|Video codec||H.264/AVC, H.265/HEVC, AV1|
|Audio codec||MP3, AAC, FLAC, MP2|
VOD allows you to splice and trim videos and perform other editing operations.
VOD supports AI-based video recognition and analysis.
Adaptive bitrate streaming is the process of transcoding video content into multi-bitrate streams. Its output includes audio/video files of different bitrates and a manifest file.
A player can dynamically select the most suitable bitrate for playback based on the current bandwidth. You can set the audio/video transcoding and other parameters of each output stream. To make configuration easier, VOD uses adaptive bitrate streaming templates to represent parameter sets. For more information, see Transcoding to Adaptive Bitrate Streaming.
The Tencent Extreme Speed High Definition (TESHD) feature of VOD uses AI algorithms to determine the optimal encoding parameters, improving video quality and reducing bandwidth loss. It takes into account the scene recognition results, the bitrate, frame rate, resolution, texture, and motion of the original video, as well as server load and ROI detection results.
Smart dynamic encoding, along with smart scene recognition, auto encoding parameter selection, and image enhancement technologies, allow you to stream content live or on demand in higher definition but at lower bitrate.
VOD allows you to quickly and easily scale and crop images by modifying their URLs.
VOD leverages AI technologies to detect inappropriate content in images. The result generated includes the recognition type, labels of the detected inappropriate content, confidence score, and handling suggestion.
