Can I put 720x480 resolution on CD-R??

[rolando1]

When I burn a DVD, the resolution is 720x480. High bitrate creates a nice picture. But what if what I want to save on a disk is only 20 - 30 minutes long. I dont want to waste a whole DVD disk, so I was wondering if I could get the same quality and resolution on to a CD-R.

yeah, but your dvd player probably wont handle it or it may not play correctly.

its known as a mini-dvd.

I just tried a 5 min clip encoded at 720x480 mpg2 at 4000kbps on a cdrw and burned as non compliant svcd on nero and it plays perfectly.Dvd player is apex 1500.

Often the limit is the speed that the DVD player spins the CD. To get the same bitrate off a CD as to the DVD, the CD needs to spin faster than the DVD and a lot of players don't support the speed. Ultimately its a case of build a miniDVD and try it out. I suggest building one with a low bit rate to confirm that the player will recognise the miniDVD and then build a couple with progressively higher bit rates until you find the limit of your DVD player.

Thanks people, you make this site great!

If XVCD = 720 x 480 mpg-1
and XSVCD = 720 x 480 mpg-2

Then what is miniDVD?

From the l/h column glossary:

miniDVD
miniDVD is a DVD video written onto a CD-R(W) instead of a DVD disc. miniDVD is also sometimes called cDVD. A miniDVD only fits about 15 minutes of DVD quality video on a 650 MB CD-R(W). Not many DVD players will play miniDVD - see the DVD Players miniDVD list for compatible players. DVDRhelp.com miniDVD page

Then what is miniDVD?

Same file structure as a DVD but recorded on a CDR, so
only approx 15 minutes can be copied of DVD video and it will only
play on a small number of DVD players.

Ok, I started this topic, and with some of your help, I managed to gather all Idea's, and pick the one I found quick and easy. Now The quality is still not as good DVD but its a little better than my old SVCD's. Ok, as Jeex, and mikesbytes wrote, the problem is that when your stand alone DVD player recognizes an SVCD, it plans to spin it at a lower speed. I found that 2520 bitrate is the ideal and sometimes the max speed for SVCD's. Only problem is that 2520 bitrate equals bad quality. DVD bitrate can be set to 9696. So with those numbers alone you can see the difference in quality. OF COURSE, there are some stand alone DVD players that can spin SVCD's at a higher rate. In fact most PC DVD player do. But In my case, I dont have one of those so I must settle with a 2520 bitrate SVCD. I did manage to get 720x480 as my resolution. I used TMPGEnc. I used the unlock.mcf file. If your TMPGEnc does not have it, you might need to update.

Video quaility is a combination of resolution and bitrate. What many people forget is that at a higher resolution it takes a higher bitrate to produce the same quaility.

Think of a jpeg file with a resolution of 1600x1200 and 40kb in size. Compare that to a 200x160 jpeg thats 40kb in size.

It's important to think about the ratio of bitrate/pixel. A 352x480 (or 480x480) 4000kbit/s encode will often look better than a 720x480 4000kbit encode.

When it comes to digital video an x(S)VCD can have the same quaility as a DVD. At the same bitrate and resolution quaility it the same. So a xSVCD/xCVD 352x480 encode is normally the best way to go given the rather low bitrates used when authoring to CDRs.

rolando1,

check out CVD. For NTSC it is 352x480 at approx 2700 kps including audio. The is a guide by satstorm in the "how to' section.

I couldn't find any other forum discussing this. Sorry if its a little off topic and long. I've encoded many 4-5 min trial runs of a 20 min DIVX 23.976 fps 200 MB video (Dragonball Z Episode)(anime). I'm trying to find out which resolution is best, but for some reason I can't determine it from the results. I encoded MPEG2 using TMPGEnc Plus, Non-interlace, Highest Quality Motion Search Precision, CG/Animation Quantization Matrix.
I encoded the following resolutions at the 1250 KB/s, 2500 KB/s, 5000 KB/s, trying to find out how the video would be affected differently (I ONLY SEE A DIFFERENCE WHEN THE BITRATE CHANGES, BUT NOT WHEN THE RESOLUTIONS CHANGE): 720x480 ; 624x416 & 544x480 ; 576x384 & 480x480 ; 496x320 & 352x480. Which resolution is best and why? 624x416 & 544x480 are both 3/4 of 720x480. Why is one better than the other? Or are they the same? Same goes for
576x384 & 480x480, which are both 2/3 of 720x480; and 496x320 &
352x480, which are both 1/2 of 720x480. Furthermore, about the bit per pixel ratio, if you give the same bitrate in a smaller resolution, you'll obviously have a better ratio; however, doesn't the decoder then have to stretch the image anyway so it can play full screen on your 704 x 480 TV? So, is it better to provide the bitrate to the full resolution or allocate that bitrate to a smaller space and then let the decoder stretch it? My eyes are hurting from trying to tell the difference. That's why i'm asking. RECAP: 1.) Is the vertical resolution more important than the horizontal resolution? If so, Why?
2.) Is it better to encode the full resolution from the beginning, or stuff it into a smaller resolution and then let the decoder stretch the image? What happens to the bit/pixel ratio after stretching? SORRY AGAIN ABOUT THE LENGTH!!!!!!!!!!!!!!!
