Hello. I own an iPad and an iPhone 4 and my Mac has a Dell UltraSharp 3008WFP 30-inch (2560x1600) display connected to it. I have a wealth of both 720p and 1080p MKV videos of various television shows and movies and I wanted to convert them to a format that would be compatible with both my iOS-based devices and would also look great on my Macs display. I started using HandBrake for converting episodes of my televisions shows. I made a new preset identical to the High Profile preset included by default and just changed the picture size to stay within 1280x720. The Constant Quality is set at 60.78% and everything else is also set at the default for the High Profile preset. Ive been using this setup for converting episodes of television shows for the past couple of months and it has worked great so far. However, when I try to convert my 1080p movies using the same preset, the resultant movie ends up with horribly clipped audio throughout its length. Can someone please help me out with this? Ive tried four movies so far and all four have been rendered useless for me by the same problem. Ive already wasted three days on this and dont want to proceed until Ive figured out how to fix this. Is my preset wrong? Is there a more ideal setting for this? Should I bump up the Constant Quality to 80%, maybe? Any help would be appreciated. Thank you.
