Converting tga files to an .avi file is a relatively painless process using tga2avi. The tga2avi software available locally here as well as here. Examples of it's use are:
usage: tga2avi <outfile> <framerate> <pattern> <start> <end> <step> examples: >tga2avi out.avi 25 abcd%04d.tga 1 100 1 Will convert abcd0001.tga through abcd0100.tga into out.avi using 25 fps. >tga2avi out.avi 24 a%03d.tga 1 900 1 Will convert a001.tga through a900.tga into out.avi using 24pfs >tga2avi out.avi 25 img.%d.tga 2 12 2 Will convert img.2.tga through img.12.tga (only evens) into out.avi
There is no documentation included with tga2avi other than the examples on the command line. Internally tga2avi uses the c sprintf function:
int sprintf( char *buffer, const char *format [, argument] ... );
The <pattern> you enter when you invoke the program is used as the format in sprintf. format and has the form:
%[flags] [width] [.precision] [{h | l | I64 | L}]type
In the above examples, 0 (zero) is used as a flag with the following definition:
0 - If width is prefixed with 0, zeros are added until the minimum width is reached.
The type used is d (integer).
Once invoked, tga2avi uses the Windows video compression utilities. The window:
Allows a compresion technique to be selected. Uncompressed appears to work universally. Other compression options may or may not work depending on compression schemes you have available. Uncompressed files are large.
