Anyone whoâ€™s ever spent time making sure a DVD looks its best knows how important the bit-budgeting process is. Understanding exactly how much space will be taken up by the features you’re trying to cram into a disc is essential to tweaking the compression on your content for maximum visual impact. Maybe you have to sacrifice a smidgen of picture quality to get that secondary audio track, or you’re wondering just how many hours of content you can fit on that DVD-R before your instructional videos start to look like bad YouTube clips.
If you’ve got an iPhone, you’ll now be able to fiddle with all those trade-offs and compromises during your commute to work, on your flight, or while you’re waiting in line at Starbucks. EditGroove
has released DVD Bit Budget Assistant
