So I've been doing further research and maybe I'm wrong or right, but hopefully some of you can tell me.. it appears there's only so far a DVD-R can go, what I may have to look at is a BD-R. Is that so?
If you are looking to burn HD content to discs, then yes. DVDs support 480p, the types of discs for HD are HD-DVD and Blu-Ray. BR beat out HD-DVD and is superior to it for the following reasons:
- Blu-Ray single layer has 2x more capacity than HD-DVD; Blu-Ray dual layer has 4x more capacity than HD-DVD
- Blu-Ray has faster maximum bitrates, in terms of raw data transfer, audio, and video
- Blu-Ray supports MPEG-2, H.264 (MPEG-4 AVC) and VC-1 encoding as mandatory
Blu-Ray supports up to 1080p. This is different from 1080i, which is interlaced (two passes interlaced), while 1080p is progressively scanned. Progressive scans are superior to interlaced ones for action scenes, the motion is too fast.
So, if you try to burn some .h264 encoded video (also known as MPEG-4 HD AVC) to a DVD, it will actually be an MPEG-2 on the disc. The difference between DVD and Blu-Ray are with what type of laser is used to burn the information, what codecs are supported, and how the information is stored on the disc. Remember, it is all 1s and 0s (bits (now think of the term "bit rate")), and for there to be "true HD," there simply needs to be more "information." DVD will not be able to supply this to you.
So when you burn a DVD or are converting to a format for DVD, go for MPEG-2 with the largest bit rate available. I still use DVDs myself but am moving into Blu-Ray. BR makes some films come to life moreso than DVD, depending on your sound system and visual setup.
- DVD supports up to 480p
- Blu-Ray supports up to 1080p
- 1080p is not the same as 1080i -- 1080p is deemed by most as true HD
- VHS was mainstream and DVD was a luxury, then DVD was mainstream and Blu-Ray was luxury, now Blu-Ray is considered mainstream and 4K is luxury
