Hello, I have a problem: I have a sequence of grayscale images, all 768 equivalent x 576 large (434k) and with range that convert into a video, so usually 120 to 180 pieces. I've already tried all the codecs, the most ingenious is the encoding of RLE32 VidEdit. In an almost incredible speed of 120 images are compressed to 3.5 MB without significant quality losses. With the "Microsoft RLE" Codec takes much longer (it must indeed synonymous to write more), and the whole is 44 MB. Cinepak lasts 10x longer and is 11 MB.
Like das That does seem to be a normal codec. This codec Microsoft RLE [32] "appears only in 8bit video, and only under VidEdit. For all other video editing programs to not synonymous with my own AVI routines (not immersed C + +, MFC, AVISaveOptions (...)).
Perhaps I can enlighten someone here yes, I know I really really well with (picture -) compression, but amazed that procedure ...
Best regards
Harald
Antwort von Stefan:
Microsoft RLE codec is a lossless codec for sources with 8 bits per pixel, ie max. 256 colors (or gray).
There are not many Programs that work only with 8 bit color depth. VirtualDub eg can not, therefore, there can only be decoded with RLE and not encoded.
Refine Probably some video codecs for those programs that do not fit on the export or work settings. Or - what I do not believe - M $ has blocked the encoder for third-party applications to take part (locked) and you have licenses. Furthermore one would have in the old SDK Video4Windows find something, but I'm too lazy to find ;-)
The "32" in the name of the codec is only an identifier that the program code can work with 32 bit data words. Much earlier, the codec has been translated for 16-bit data words, there is missing the 32 in the name.
