Blu-ray is becoming a more accepted format these days, but many people still have more DVDs than Blu-ray. From time to time, we get requests for help on making compilations of DVD-Video to put on a Blu-ray disc. This guide is intended to show you how to do this.
Full resolution DVD-Video is, by definition, within the specifications set out for Blu-ray. This does not mean that putting it on a Blu-ray disc magically transforms the DVD into high definition. It simply means the Blu-ray standard can accept many different resolutions and types of audio and video, and most anything that is already in DVD-Video format is automatically compliant to the standard definition sections of the Blu-ray standard. There are exceptions of course, as DVD-Video also has some variations in resolution and can have MPEG-1 in certain instances, but commercially made DVDs will either be 720 x 480 or 720 x 576 resolution, with MPEG-2 video and compliant audio.
So, what does that wordy paragraph actually mean? Simply put, it means that you almost never have to re-encode DVD-Video or lose any picture quality when converting to Blu-ray, especially when working with commercially made DVDs.
The problems inherent to this process are centered around making a working menu to select each video in the compilation. There are several different ways of approaching the problem, and there is one program that can do all of the steps by itself. It is called MultiAVCHD, and it is free to download and use. Unfortunately, the output from MultiAVCHD is not universally accepted by Blu-ray players or media player programs in computers. But for most people, MultiAVCHD does a fine job. You would simply have to test its output in your players.
I am going to outline a different approach, using some other free programs. They are AVStoDVD, DVD2BD Express, Vob2MPG and possibly PgcDemux. I say possibly, because using PgcDemux is optional, and only necessary if you need subtitles.
