Hello all I have just gotten mainconcept because the speed of TMPGenc is just too unbearable... i read through the quick guides available to the product but have not really gotten a thorough understanding of how to use the program... i understand how to use it other than how to fix aspect ratios to fit the picture so it does not stretch... any suggestions?
Look in the crop and scale section. Don't change the output, leave it at 720x480/576, but hit the Crop and Scale button, and resize it to what you need, so it's letterboxed properly. You'll have to open the video in Gspot first, to see what the framesize/aspect really is.
