  1. I have 1 video files. Both 700+mpg. they are SVCD streams in 480x480.

    Well dvd players cant read that so it needs to be in 720x480, i encode them along with the audio since SVCD audio is 44.1k. Well dvd needs to be in 48K and that leads to syncing problems.

    The files are m2v so i cant import them to imovie 4.0 . Sthe SVCD>DVD features try to slow down the audio, but the sync is way off.

    So no, ffmpegx, mpeg2works, imovie, and such dont work. What is the best way to convert the damn two to have em match up. and forget about bringina ny of those files into imovie, because i movie is sucky unless its off of a cam.

    I have asked this audio question before and NOONE can answer. I found it hard to believe that NOONE has done this before.
    Thanks

    lots, if not most DVD players can handle 480x480 video.
    If it isn't broken, take it apart and find out why.

  3. what you need to do is demux the audio and video streams.
    convert the mpg1 to mpg2 if it is an mpg1 stream. if it's svcd it should already be in mpg2 format.

    then you need to take the audio stream and resample to 48000 using goldwave or some other program that can resample. keep the audio as pcm or convert to ac3 audio.

    once you have the video and audio files converted to the proper formats, you want to multiplex the files together and author using a dvd authoring program such as tmpgenc dvd author.

    there are a lot of guides on this website that show you how to do this.
    So, I guess what I'm telling you is that there are a lot of people who have converted svcd to dvd.

    The question you should be asking yourself is have you tried looking through the various guides????!!!!

    dafreak,

    Perhaps you did not notice, but this posting is in the Mac Video Forum.

    I'm not familiar with doing these kinds of things on a Mac. I like macs, and I own one....but once I got serious about downloading video, burning SVCD's, encoding AVI's, and authoring DVD, I bought a PC! Maybe it's time for the originator of this thread to do the same -- PC's are cheap, and you can set it up so it shares monitor, keyboard, etc. with your mac.
    And "no one" is two words...

    Theres no good reason to buy a PC for working with video. More important, however, is the ability to write clearly and understandably, which I believe the topic starter lacks. And the ability to determine which forum one is in, but I guess thats asking to much. (referring to second post)

    Speaking of some thing totally different, I always read it as someone yelling NOON! NOON! with more emphasis on the 'O' section. Like a cow, but weirder. NOOOOOOON!

    As for the actual problem, as I stated earlier, I find it difficult to understand the poster, so this is just a guess as to what is really going on. You have SVCD files, and you need DVD files because your DVD player may or may not play SVCD files. So, we need to convert the video to DVD. Its too bad you're not using CVDs, but that can't be helped at this point. Okay, so you've got the encoded video and audio now, but apparently they don't sync nicely. You believe that the reason is that the audio is sped up, which seems weird to me, because that shouldn't happen. Maybe I'm just not experienced enough with encoding audio, but I've never noticed anything like that happen. Could you check to see what the exact lengths down to parts of a second if possible? For both the audio and video that is. Before and after, if possible. Use this table:

    Before
    Video: hh:mms.framenumber
    Audio: hh:mms:ms
    After
    Video: hh:mms.framenumber
    Audio: hh:mms:ms

    Okay, if you don't want to do that, try authoring your DVD with the valid 720x480 Video, and the 44.1Khz audio. Maybe your DVD player won't care, and that saves us a lot of work.

    Let us know how this works out.
    If it isn't broken, take it apart and find out why.

  6. It shouldn't be necessary to reconvert the video; most players can handle 480x480 even though it's not an official DVD resolution. The problem's more likely with the 44.1kHz audio, as most DVD players still expect 48kHz audio on DVD media.

    You said you've used ffmpegx, so try this with the first mpeg:

    * demux the mpeg (ffmpegx Tools tab).

    * keep the m2v file. throw away the mp2 file.

    * open the mpeg in ffmpegx. Choose the "movie audio to mp2" preset (best to Save As the same base filename as the m2v file) and hit Encode.

    * see if you can make a successful DVD image using the m2v and new mp2 using Sizzle .1's Elementary Streams setting.

    If the image works in the OS X DVD Player app, repeat the above process for the second mpeg, then add the resulting m2v and mp2 as the second chapter in the same Sizzle DVD setup.

    If you need to make this kind of conversion often, paying the ffmpegx shareware fee unlocks a feature that automates the demux/convert audio/remux process, then creates a VIDEO_TS folder for burning. It'll work on a single file or a folder full of mpegs and/or disk images.

    Both ffmpeg and mpeg2works can do what you're asking. Why do you say they dont work?

    That's weird. I thought I've seen most of your 7 posts. I don't remember you asking this question.

    Cheers!

    well if you want to author the dvd to proper specs and use a program like dvd studio pro you gotta re-encode the video.. i personally have never gotten the mpeg-2 mode to work with ffmpeg chosen as the encoder in ffmpegX, however i find that ffmpeg the binary itself is the best tool to use to re-encode mpeg-2... if you want to use it in the termy i suggest going to
    ffmpeg.sf.net/cvs and compile the binary yourself. If i was at my house i could give you settings to use to re-encode the entire thing without having to demux the audio and video. But i use ffmpeg to re-encode from SVCD->DVD all the time. This is totally possible, and no u dont have to buy a pc!

    Well, I looked at another of FatFreeVW's posts, and he already has a PC!

    In that case the solution is much simpler than what people are suggesting here. There is no reason to re-encode the video. You can author SVCD to DVD on a PC easily with only 2 apps: DVDPatcher (free) and TMPGEnc DVDAuthor (trial available). With DVDPatcher, you simply patch the video's so they *appear* to have resolution 720x480 (takes only a few seconds). Then you can easily import them into DVDAuthor (or any other authoring app you prefer). DVDAuthor will automatically re-encode the audio for you to 48k. Provided your source MPG's are not loaded with errors, there should be no problem with synch.

    If you re-encode SVCD to DVD, quality will go down and size will go up - don't do it!

    quality go down?!?! what are you talking about? as long as you use the same bitrate and some high quality settings the quality doesnt go down at all.. nor does the size go up, just cuz you use a higher resolution the size doesnt go up, and if it does its minimal at best. u can patch the video on mac too using gumby, but some dvd players wont properly display patched video.. hell sometimes my dvd player displays it properly and sometimes it doesnt, (its odd it seems like some progs patch it differently) but yeh you dont HAVE to re-encode but its preferrable to get the highest level of compatability.

    if you want to go the patch route u can still use a mac.

    Suggestion...use Gumby if you're on a MAC

    this way the VIDEO isn't re-encoded..
    THE HEADER is patched to fool the AUTHORING program
    RE-ENCODING increases file size and dulls quality for sure!

    im still going to disagree with it dulling quality.. i re-encode my tv-rips all the time and use hq settings and same bitrate and i never lose any quality or experience any dulling of video at all. i 100% disagree

    Look, whenever you re-encode something, quality will go down. If you use a very high bitrate, then the decrease in quality will probably not be noticeable.

    The only way size would not go up is if you used an SVCD bitrate for your DVD-resolution encode....quality will be noticeably degraded if you choose to do something like that.

    Whether or not the quality is noticeable depends heavily on what you're watching the result on. If you just have a standard TV, then yes, you can get away with encoding low-bitrate DVD and not notice a difference....but you'll regret this choice the day you upgrade to an HDTV.

    Re-encoding doesn't make it lose quality.
    Stupid re-encoding makes it lose quality.

    Maybe I shoulda said, "patching prevents accidental mistakes in re-encoding that may compromise quality"

    all i have to say is i do SVCD to DVD all the time... infact theres a tutorial on the subject on my website.

    so i am telling you "Most everyone has converted a SVCD to DVD"

    well lets see.. i cap tv eps on a regular basis, re-encode them and then watch on my 65 inch mitsubish HDTV and i do not see a quality decline.. so i beg to differ still.

    Smurf has pointed out that you may be in the right if you choose the correct setting, but Bilestile when you say:
    i cap tv eps on a regular basis, re-encode them and then watch on my 65 inch mitsubish HDTV and i do not see a quality decline
    You're not re encodeing but TRANSCODING..
    we were discussing changing resolution of a file already in the needed format hence RE-ENCODING

    I think unless you caputre direct to MPEG-2 with Wired Media Press orADS Instant USB, you're ending up with either a QUICKTIME MOVIE (mjpeg) or DV

    Re-encoding means converting from one lossy format to another lossy format. When you do your capping, you're capping to a very high-quality, probably lossless format. Of course you're not going to see any loss in quality if you're encoding (note, not re-encoding) to DVD from a high-quality DV source....you're already creating something that will have the highest quality possible....you're not trying to upscale the resolution, like the originator of this thread is trying to do.

    see you say "unless" like you KNOW im capping to DV or mov.. and i in fact have the ads instant dvd.. and please dont you people lecture me like i dont know what im doing i've been doing this shit for a LONG time.. I'm capping to mpeg-2 and REENCODING (yes you tards RE-ENCODING not TRANSCODING i know the difference) and i see ZERO quality loss on my HDTV so before you go thinking you know everything, be sure you know ANYTHING

  22. Well this thread has gone off the rails. If you are happy with your quality then Yaay! If not then study up on how to transcode, or re-encode with minimal loss. Finally read the f***ing sticky. See there where it says the topic SVCD to DVD has been discussed before and gives a handy link to Galactica's website? Use it. Yeesh everyone chill, take a swig off you beverage of choice. Lazy folks suck!

    okay im sorry i flew off the handle, i woke up this morning to a broken toilet and a two story house with both stories flooded and ALOT of water damage. and then had a grueling day of classes.. its easy to fly off the handle after that


    (but on a note of capping i used to cap in MOV uncompressed back in the day in os 8.5-9.2 on my ATI vr 128.. so i really have done it all ) but again didnt mean to sling mud (eventhough i know im notorious for a bad temper).. but seriously there is very little about mac video (excluding rouge open source containers like OGM and all the millions of codecs that can fit in the AVI container) so please if i say something i dont say it out of ignorance i say it out of tried and true tested YEARS of experience with every mpeg encoder that has ever been on the mac.. from astarte m.pack to ripping with astarte cd-copy and using astarte dvd copy (or whatever it was called before apple purchased it) or the early versions of cleaner, messed with almost every version of mediapipe out forwards and backwards.. know mpeg2enc and almost ffmpeg like the back of my hand... need i continue? every decoder- mplayer, movtoy4m ppmtoy4m all the mjpeg tools... enough said

    Good thing(NOT) I'm back on dialup...
    I RECCOMEND IT as a highly humbling experience....

    AS SOMEONE who also can fly off the handle I'd like to apologize for not realizing how much I could learn by keeping my mouth shut.
    Don't we love to type away and "show off"? Sorry...
    I'm RE-ENCODING NOW TOO!
