Audio and video processing

Digital Watermark Copyright Protection

Watermark carrier

It supports embedding/extracting watermarks in images and videos.

Watermark Type

Support the embedding of image and text watermarks.

Anti attack of video extraction watermark

It can resist attacks such as bit rate change, image zoom, image occlusion, brightness/contrast change to a certain extent. It supports extracting digital watermarks from videos after recording.

Image Extraction Watermark Anti attack

It is able to resist a certain degree of screen clipping, blocking, scaling, and screenshot attacks

Standard audio video transcoding

Fast transcoding

The AI model predicts the slicing strategy, and the transcoding speed can reach 50 times.

Instant transcoding

Support h264/265 inter conversion to meet the user's demand for smooth player while saving storage costs in live stream recording and playback of live video scenes.

Perceptual coding

Realize the transmission of on-demand and live broadcast services at a lower bit rate, and at the same time bring users a higher quality experience.

AI video processing

Intelligent green screen matting

For green screen recording scene video, it supports automatic deduction of portrait and generation of transparent channel background video.webp. Add any background to the generated video.

Black edge detection and clipping

Solve the black edge phenomenon of picture redundancy caused by the change of equipment size during the secondary distribution of video. On the one hand, it can improve the user's perception, on the other hand, it can save the bit rate and reduce the file volume.

Intelligent subtitle removal/watermark removal

Intelligent removal of dominant watermarks/subtitles in the video is applied to video transportation, secondary editing and distribution scenes.

Intelligent horizontal to vertical rotation

Identify the important people and wonderful areas in the picture through the target detection algorithm, and dynamically adjust the window position to change the video from horizontal screen (16:9) to vertical screen (9:16).

Intelligent frame drawing

Brightness detection

Detect video clips that are too bright and dark (including full black screen and white screen) beyond the comfort range of human eyes.

Noise detection

Detect video images mixed with bands, ripples, meshes and other pieces with periodic superimposed noise.

Blocking/field effect detection

As the bit rate of the detection video decreases, there will be discontinuous segments at the boundary of the block, forming obvious defects in the reconstructed image. Detect interlaced segments in image motion caused by compression in video post-processing stage.

Volume detection

Detect audio clips with too high/too low volume that are beyond the comfort range of human ears. Detect the intermittent audio clips caused by unstable signal source input during recording.
