The invention discloses a
system for video material frame-accuracy
cutting, which comprises a video index creating module and a
cutting frame image set recreating module, wherein the video index creating module extracts frame index information of each video frame of video material and saves the information at the
tail part of the video material; and the
cutting frame image set recreating module reads the frame index information at the
tail part of the target video material, rapidly positions the cutting points of the target video material,
decodes and re-codes the video frames of the cutting points and the relevant frames of the video frames, encapsulates the re-coded video frames in the original image set and modifies reference
time information. The invention additionally discloses a method for frame-accuracy cutting by using the
system. When the invention is adopted to conduct frame-accuracy cutting, the video frames of the cutting points or the video frames close to the cutting points are required to be re-coded only, and thereby the real-
time frame-accuracy cutting of the video material is enabled to be more flexible, high-efficiency and accurate and the defects such as mosaics existing at the cutting points of the video material are avoided.
