Camcorders forum: Can a regular DVD burner copy HD video to a Blu-ray DVD disc

can deal with burning data files to CDs (700 MB), single layer DVDs (4.7 gig) and double layer DVDs (8.5 gig). The laser is red.

Blu Ray discs start at 25 gig and require a blue laser to burn the data to the disc.

and are used by Blu Ray burners only

A regular DVD can write an MTS data file and the BluRay player should play it. Note the storage difference - even the double layer DVDs will hold only a few minutes of high quality MTS video file.

Personally, I am skipping Blu Ray and working the Network Attached Storage (NAS) multi-drive (RAID1) stuff... downloadable movies basically makes Blu Ray obsolete - unless used for gaming or you are really into the "extras" and behind the scenes stuff). But that's just my opinion.

whether that MTS file is stored on an optical disc, flash memory or hard disc drive.

"Blu Ray" is not a digital video file type - but it is a technology that allows high capacity data storage using a blue laser to read/write the data bits more densely that regular red-laser DVD devices.

Is the .MTS file same as Blu-ray or different?
They are mutually exclusive. But Blu Ray devices can read MTS data files on optical discs (Blu Ray-burnedonto Blu Ray disc or red-laser burned by regular DVD burners onto regular blank DVDs).

Does a regular DVD burner have a blue laser?
No. As stated, a regular DVD burner uses a red laser to read/write data files.

If no, how could it burn the Blu-ray disc?
The regular DVD burner cannot use Blu Ray discs - the regular DVD burner can use only regular (non Blu Ray) discs. There is no "Blu Ray data file" type. The regular DVD player can burn MTS data files to a regular blank disc - and the Blu Ray play can read that MTS file (backward compatible).

Because high definition video uses lots of space, using regular blank DVDs can be challenging because they don't hold much (compared to Blu Ray blanks). Remember, best video quality comes from least video compression.

If you need more, someone else will need to jump in. Like I said, I am skipping Blu Ray. In my environment, it is already obsolete and irrelevant.

In this case a video data file. A spreadsheet or text file does not change when it is copied to flash memory, hard disc drive, optical disc or other storage media... a video file won't change, either - unless you change it.

If there is no change to the data file, there cannot be any change to the video quality. Change the data file and the potential for video quality exists.

I am copying a DVD. (keep in mind my computer does not have a blue-ray player/burner.)

When I open My Computer it says the disc is only 1.7gigs. BUT, when I open the disc and check the properties it says the VIDEO_TS it is telling me the folder size is 22gigs. When I open the folder there was 12 sets of IFO/VOB files but they are all the same thing.

I can go the long way and just grab any of the 3 VOB files convert them to MPEG2s then back to DVD and it comes out to be around 2 gigs.

My question is how did they fit 22gigs on a DVD disc. And, can I even get a 22gig blank DVD. Never seen this before and am not sure what I am looking at. Any help would be grest.
