DVCorrector

DVCorrector takes a video clip (NTSC or PAL DV AVI file) as an input, displays a histogram of the DC coefficients of the video frames (Y - brightness, Cr - red and Cb - blue) and allows to modify these coefficients by applying a simple translation to all coefficients of the frame.

The resulting effect is a global brightness correction and/or color correction applied to the whole clip, without decompression/recompression, i.e. without introducing any quality loss.

DVCorrector input are exclusively AVI DV type 1 or 2 files. The output file is an AVI file of the same type as the input file, containing the either the full input file or a selected sequence within this file.

DVCorrector may also be used to fragment a large AVI file or to extract scenes from an AVI file.
