- RawRip v. 3.0 - By Mike Negus
-
- First read the DMPEG.DOC file to learn how a RAW file should be created from
- an MPEG. Once you have created a RAW file with DMPEG (either 8 or 24-bit with
- the -d4 option) you can run it through my RawRip program to create a DIB, TGA,
- or RAW sequence.
-
- The 24-bit RAW and TGA (TARGA by Truevision) sequence files can be edited by
- any editor supporting these formats and then reread by CMPEG again to recreate
- a bitmap. In effect you can decompress an MPEG edit it and the recompress it.
-
- The DIB files which my program can also create is compatible with the BMP file
- format. This sequence can then be used by Microsoft's Video for Windows to
- create an AVI or each DIB file can be edited by any Bitmap editor. You will
- need the full VFW in order to create an AVI. The VIDEDIT utility will read in
- DIB files.
-
- There are three options that I've incorporated with this program. The first is
- a promote option that will take an 8-bit RAW file created by DMPEG and
- automatically create 24-bit sequence files instead of 8-bit ones. 24-bit files
- are supported by CMPEG and the 8-bit TGA and RAW files would not work.
-
- Another option is the start frame option which allows you to start conversion at
- whatever frame in the sequence you choose.
-
- The other is a lightness option which lets you lighten up the sequence if it is
- too dark. The range of this option is from 0 to 255. 255 lightens the most
- and will give a bunch of white frames. I've allowed numbers greater than
- 255 because it creates "neat" effects like a negative does. Try a lightness
- factor of 450 or 1000 to see what I mean.
-
- USING RAWRIP:
-
- To use RAWRIP you need to use the command:
- rawrip <filename.raw> [t<type>] [p] [s#] [l#]
-
- filename.raw = The RAW that you want to rip.
- t<type> = You have three choices "td" for DIB sequence, "tt" for TGA
- sequence, "tr" for RAW sequence. Default is "td".
- p = promotes an 8-bit RAW to a 24-bit sequence. Default is no promotion.
- s# = starting frame #. "s29" will start at frame 29 counting from 0. So
- actually it is frame 30 that it starts at. Frames start at 0 by default.
- l# = lightness factor. Range is from 0-255 and lightens the sequence. I found
- this useful at times so I left it in. Try a number > 255 and cool
- things happen to the colors of the images.
-
- for example:
-
- rawrip test.raw
-
- Creates DIB files starting at frame 0 w/no lightness factor and no promotion
- to 24-bit.
-
- avirip test.avi TT P S50 L30
-
- Creates TGA files starting at frame 50 and using a lightness factor of 30.
- If test.avi is 8-bit then 24-bit sequence TGA files are created.
-
- Both commands create a test.txt file with a listing of sequence names. But
- the last one creates a batch file to make an MPEG since CMPEG compatible
- TGA files were created.
-
- I had a lot of fun making this program and figuring out the DIB/BMP formats so
- this is FREE to whoever wants it. If you have a program that creates MPEG's
- or does what my program does but better AND IS SHAREWARE then please post it on
- the INTERNET for others like myself to get and use.
