  1. I have a CD burner, and i dont think i'll be getting a dvd burner any time soon.
    I have downloaded a mini-DVD sample and tested it in my dvd players. 2 out of 3 of my players can play it, including the one i use most often. (CyberHome CH-LDV 700B)

    My question is...
    How do I author a cDVD? Is it just simply a matter of using a dvd authoring program and keeping the size under 700MB... then burning to a CD-r/rw?

    If i am incorrect on this assumption, please correct me. thanks...

    That's my belief also, though I've never done it so may be wrong.

    All I'd say is the audio probably needs to be at 48KHz for DVD specs...

    @ canadateck -

    SVCD is MPEG2, same as DVD, but a lower bitrate.

    As I undertand it, MPEG2 that exceeds the SVCD specs (in terms of bitrate) but is on a CD is cDVD or mini-DVD.

    In fact, SVCD is also at a lower resolution (480 x 480 / 576) where DVD is at 720 x 480 / 576 and the audio in a SVCD is at 44,100Hz whereas DVDs are 48,000Hz.

    So, no, not an SVCD.

    EDIT: See miniDVD in the Glossary, and also the difference in SVCD and DVD in the specs under "What Is... SVCD/DVD" in the top left of the page.

  8. A player that plays VCD/XVCD pretty much everything,what are the chances of it playing cDVD?

  9. So theres noway to burn DVD specs 720x480 48,000hz onto a CD? I always Burn to DVD.

    Yes there is - that's the whole point of this thread.

    A DVD compliant MPEG2 file authored to get your VIDEO_TS and AUDIO_TS folders burnt on to CD is a cDVD / mini-DVD.

    Only problem is you'll only get about 15 mins of footage on to a CD.

    No probs. Just be aware that, typically, not many DVD players play them...

    Remember, search is your friend

    To answer the OP, just author as per normal as if you were putting it to DVD. Then burn it to CD, keeping the VIDEO_TS and AUDIO_TS folder structures as-is, just as you would a DVD.
    If in doubt, Google it.

    So, just to verify... in Nero, I simply burn it as CD-ROM with the VIDEO_TS and AUDIO_TS folders in the root directory. Correct?

    Yep. Should create the exact same thing you downloaded. Good luck !

    ... that's only if you use exceptionally high bitrates ...

    If you use 352 * 240/288 video and 48KHz audio, you could get away with 74/80 minutes @ vcd bitrates - 1150 video, 224 audio.

    Similarly 352 * 480/576 and 48Khz audio, you could get away with just under 34 minutes using 3000kbps for video and 224kbps for audio.

    Lower the bitrate, squeeze more time on, squeeze more quality out though, unless you look at 2-Pass VBR ...
    If in doubt, Google it.

  22. yeah, i was thinking of 352x480 with relatively low bitrates, probably with VBR.

    I generally decide the bitrate i will use when i figure the length of the feature and the file size limit, which in this case is 700MB. 800MB if i use 90min CD-R's but i'm not sure if my burner supports them, as it is a no-name brand.

    Do this (assuming NTSC):

    1. Encode your video to either MPEG1 352x240,29.97fps or MPEG2 352x480,29.97fps or MPEG2 720x480,29.97fps--one of the valid specs for DVD.

    2. Encode your audio to 48kHz, either AC3 or MP2--somewhere around 192 or 224 kbp--also valid DVD spec.

    3. Main thing to worry about is acceptable bitrate. Start with short sample clip. Do 7000-8000 kbps, 5000-6000 kbps, 3000-4000 kbps, 2500 kbps, 2000 kbps, 1500 kpbs, then choose which one works best. It's not that the player can't decode fast enough, it's that the DVD drive isn't built to spin CD's that fast. When CD's and DVD's run at the same angular velocity DVD's are giving ~3x--9x more data AKA bitrate, so CD's to give same expected bitrate have to spin much faster and most settop players don't have standard computer ROM drives in them, so they aren't always built like most ROM's these days that would allow 24-56x CD reads.

    4. Author in your DVD authoring app of choice, but compile the title to VIDEO_TS folder (with the IFO's, BUP's and VOB's).

    5. Open Nero, select either [ CD-ROM (ISO) ] or [ CD-ROM (UDF/ISO) ] (as this is the filesystem an actual DVD would have). Put your VIDEO_TS and AUDIO_TS folder in the root of the disc and NOTHING ELSE. May even want to try it without AUDIO_TS folder. The Nero DVD-Video template knows to put the files in a particular, contiguous order on the disc, and to not put anything else in the VIDEO_TS folder, but the CD-ROM templates don't, so you'll have to be vigilant on this. You may also want to try padding the remainder of the disc so that the lead-out finishes at the true end of the disc (to make it act more like a compliant DVD). Burn.

    Let us know how it goes...

    HTH,
    Scott

    ********
    edit--to add padding, after 1st putting in the VIDEO_TS stuff, put in a file of all zeros of enough length to fill out the rest of the disc (use a calc.). This can be created by most audio apps (Cool Edit, etc) by creating a file of "Silence" and saving as raw LPCM (not wave). Then make sure after it is added to the disc image, the "Priority" of the file is set to "LOW" so it will be put at the end. Might as well make it hidden, too.

    Also has been already mentioned, but once again...

    Since you're already compromising the data somewhat--eek out every ounce of bitrate efficiency you can by do 2- or more pass VBR, with High search precision, 10bit DC, lots of DNR and smoothing, and Black cropping if needed. Also, sacrifice a little audio bitrate if it can make the difference in the video (I'll be shot by my Audio Pro peers if the hear that one!).

    Author a DVD, but keep size small enough for CD.
    DVDit! has an option for this too.

    You need to check that the DVD players can handle the rotational speed by building a miniDVD with bit rates of say double that of a SVCD.

    ok, I haven't tried burning a miniDVD as a CD-ROM, but in Nero you have one dedicated option for miniDVD. I have Nero in Italian so the terms may differ, but upon opening startsmart, go to CD in the top scrolldown menu, then video, and you should see "create miniDVD" or something to that extent. The few times I've tried it it never let me down.

    Actually, I did look at the videohelp.com page on miniDVD before posting. it did not give me specific details on how to author such a disc. And i did search the forums to find a thread similar to this one. didnt find one. so i searched the web, and found a website on miniDVD, where i found a sample image download, but no details on how to author.
    So then I came here to see if anyone would know how to do it.

    The only options I have there are VideoCD and Super VideoCD.

    Yeah, I was planning on using Half-D1 resolution with 224kbps MP2 audio @ 48kHz. I am using the TMPGEnc template for 'NTSC DVD Low Resolution', only I modified it to 352x480 resolution.
    3. Main thing to worry about is acceptable bitrate. Start with short sample clip.

    I intended to use a bitrate not too far from SVCD limits (2150/224) to be sure the disc can spin fast enough. most of the source material i work with is badly compressed, so i'm not too concerned about bitrate.
    4. Author in your DVD authoring app of choice, but compile the title to VIDEO_TS folder (with the IFO's, BUP's and VOB's).

    Let us know how it goes...

    HTH,
    Scott
    The UDF/ISO formatting sounds like a good idea. I'll try it. However, I don't see why I would have to use padding to fill the disc. It seems like a waste of time to me. The disc does not need to be filled to the brim in order for it to be playable...
    sorry if i missed the point on that one.

    When I burn a CD-ROM with the AUDIO_TS (which is empty for some reason) and VIDEO_TS folders... Nero says, before burning, "sorting DVD-Video files..."
    I'm assuming it does this when it notices the file structure?

    Well, I believe my post is long enough now. i wonder if anybody will even read the whole thing...

    I read it...

    ...and have to apologise for a curt response yesterday. Someone rattled my cage and you got a bit of what was left over after I laid into them...

    I'm not justifying my curt response, but it'd be useful if you say you've searched, what you've read etc. so people know you've done the leg work, and so they can read the same stuff too, to see if they can help explain it differently.

    Invariably, the AUDIO_TS folder is empty. This folder is a relic from the days when audio DVDs were on the cards. It's stil best to burn it, even though it's empty, coz some DVD players look for both folders to identify a DVD disc.

    So, you say you burn the AUDIO_TS and VIDEO_TS folders onto CD-ROM. Does it work OK now? Bearing in mind some (probably quite a few, from what I've read) DVD players don't play them...
