Hi Scraggy,

VirtualDub is freeware... and can be downloaded here... -->
https://www.virtualdub.org/

e.g. this tutorial on how to use VirtualDub to compress it with DivX... -->
https://www.jhepple.com/support/divxvirtualdub.htm

some other information...
https://www.jhepple.com/virtualdub.htm

just make sure your rendered images from Maya, is in bmp format, and that they have cronolygical numbers...

e.g. file001.bmp file002.bmp .... file999.bmp, and then when you want to open it in VirtualDub use "DIB Imagesequence .bmp" and click on file001.bmp, and then VirtualDub will load all the images as a movie/film... which you then can compress... VirtualDub can also add sound to the movie...

I don't know which soundeditor program you use, but I can suggest you this fine freeware program... "Audacity"... -->

if you e.g. want other format's than avi, you can e.g. get this "MPEG-2 Upgrade for VirtualDub" here... -->

I have heard VirtualDub also should support, Targa, but if is's true I don't know... I can't see it in selected file options... It can maybe be one of those modifications of virtualdub which exist out there on the net...

regards

Strarup
