adventures with tgawarper

To go forward with the mirrordome project, purchased the tgawarper software for windows from LochNess. It appears to have some bugs, as the product page itself notes -

When using the "-o output filemask" option and the filemask contains a folder
structure or drive letter, the program will prepend its "w_" onto the filemask
instead of the actual filename — instead of creating "d:/output/w_filename.tga",
it will create "w_d:/output/filename.tga" (which will likely fail). So you may
have to be creative in order to use this feature in its current implementation.

My workaround was to copy the exe to the folder which had the input images, and run it from there without the -o option, so that output also goes to the same folder.

Time taken: for
tgawarper -w 1920 -a 5 s3_%04d.tga EP_xyuv_1920.map
it took approx 2.9 seconds per frame on my Athlon X2 Dual Core @ 1.9 GHz. 36 seconds of 30 fps video, 1100 frames in an hour. Later, using Virtualdub and AVISynth to make a 6 Mbps HD movie using XVid codec, approx 2.5 fps rendering speed. The AVISynth input avs file was using ImageSource, an avs file with the following lines:
video = ImageSource("w_s3_%04d.tga", 0000, 1110, 29.97)
audio = DirectShowSource("C:\My Path\myfilename.mov")
return AudioDub(video, audio)
