I've captured a video from a source and I want to convert it into MP2 file to author it and burn on a DVDR. As I'm not interested in high quality, I was wondering to put 2 clips into a single DVDR. When I convert using TMPGEnc, I can select how much space in % the video has to be. If I use 50% for first video and 50% for second video, I'm not sure if I'll find the space to author it and then burn it. Any suggestions ? Using 49% and 49% ? How much space does the authoring take ? I plan to make a simple menu with clip 1 or clip 2 choice. Thanks for your answers !
