CVD:What is it,how to test it & what to expect!

[campa]

Hi Boys,
please help me with making CVD in TMPEG. I can't set 2 PASS VBR. When I set it up it doesn't work. I have instaled Win XP. Please help me where shoulb be a problem. Thanks

[adam]

Load the unlock.mcf template. This will unlock all settings.

You didn't understund me. I can set 2 PASS VBR, but it doesn't work. It calculate nothing.

[Martyn1980]

Have you set a minimum maximum and average bitrate, because sometimes all three will be on zero and it wont do anything.

Explain your problem in a bit more detail or you will get people misunderstanding your question, what exactly does it say, can you set your bitrates, can you click on start, Tmpeg does nothing but analyse the video for the first pass, so dont expect to see a picture until it reaches 50%, in case thats your problem.

Just covering all bases

[campa]

Once again,
I set up 2 PASS VBR, I set max. bitrate , min. bitrate and average bitrate and when I started to calculate it doesn't calculate anythink. I think that the problem should be in WIn XP.

Campa, when you start encoding a video with 2 pass VBR, the 'encoding preview' screen will just be completely black for half of the encoding time, whilst it is doing the 1st pass. When I first started doing 2 pass VBR I too thought it wasn't working... are you sure it's not just this happening?

[campa]

Hi,
when I started it, it's really black, but elapsed time and source position are 0 and caltulated frame is also 0.

[adam]

Is the % progress increasing? If so then everything is fine. Once it gets to %50 then the encoding will actually start.

First I wanted to say ... woopie CVD does work.
I never though of using lower resolution to get better quality but ... it realy looks better from the SVCD's I tried to make.
Additionaly, I was able to view it on by brother "old" Toshiba SD1200.

I wanted to ask if anyone can explain the "Sharpen" function in the TMPGen.
I am using 2.56 and there are only 2 sliders or 2 values that I can enter (one Horizontal and the second Vertical)
I read in the article that:

"There is a way to to eliminate this :Use sharpn filters when you encode.
With TMPGenc plus for example, if you use the sharpen edge filter and the values 8/16/24/32"

What are the parameters to use?
Do I put 8 as vertical and horizontal or maybe it is 8 Horizontal and 16 vertical or vise versa.

Kind of a long question hope it will be uderstandable by some one.

[SatStorm]

Use 8, 16, 32 or more on BOTH sliders and also mark "Field base" if your source is interlace.
That way, you sharping the picture a lot.
Currently, I using values 32 and 48 myself.

[Cybid2001]

Hey guys,

I have a question conerncing a DVD-compliant CVD-file. I encoded the avi-file with all the parameters as described in the guide with TMPGEnc. When I try to author the resulting mpg-file with Ulead's VideoPack, though, I receive the following error in the compability check: "System [error, in red]: Muxrate 2222800 bit/sec".

What's the problem? Did I forget to alter a setting in TMPGEnc?

Thanks for your time,

Cybid

Newbie question:

If I capture at the appropriate specs for my MPEG2 file, how can I burn the CVD without NERO. I have Roxio CD creator paltinum which has VCD (No SVCD). Is there a freeware that I can use to do this? Do I simply treat it as a SVCD, but use the MPEG file encoded at 352x480 etc.? All the posts and guides kind of drop the ball at this stage of the process....

[energy80s]

No, you must have an SVCD capable burning program. CVD's can't be burnt as VCD's.

[magicmycote]

I believe TSCV (freeware) will accept a CVD, just burn it as an SVCD.

[Kevin Henry]

I just finished making a CVD of Lord of the Rings in CCE.

I used 1180/2520 & 1300 bitrates - 1300 was supposed to be 1600, but I screwed up but even so - the quality was brilliant. I'll redo it and see if there's a difference.

Also, if you have less than 50mins per cd, you can do one pass VBR in CCE and set Q=1 1180/2520 & that gives EXCELLENT quality - and is bloody fast. Can encode 50 mins in about 35 mins, as opposed to 3 pass which takes about 2 hours per CD.

I can post a link to my CCE templates if you want ...

CVD is the bomb!

Use TMPGEnc to mux the .mpv, .mpa files - I use the header trick to play in my standalone.

Then, add the file to VCDEasy but turn off the 'Perform some MPEG compliance checks' and you can burn it fine. I make a label & some chapters but cant be shagged with anything else.

[SatStorm]

Pushing CVD that low it might give some good results in some movies, but for most movies an average between 1700 - 2300 is needed.
Myself made the "imposibble" couple of times, for example I have in one CD @ CVD format movies like SHREK, DrDoolittle 2, Highlander 4, etc but those was 2 11 1 aspect and that way this is possible (the active window in the screen is about 1/2 of the whole, so half bitrate needed compared a full 4:3 picture). With typical 4:3 picture, any bitrate lower 1700 gonna look awfull

[Kevin Henry]

I'll keep that in mind, but most of the movies I've downloaded are widescreen format ...

[dvfan]

can someone please help me everytime i try to create a cvd and play it on my powerdvd on computer looks great but on my dvd player on tv the picture rolls, anyone know why?

[W_Eagle]

A dumb question, if I may:

CVD has all the efforts of the well known SVCD, but with 1/2 D1 resolution (some call this resolution D2).
This 1/2 D1 (352 X 576/480), happens to be a legal resolution for DVD - Video also.

The official D1, or DV, or DVD resolution is 720x576/480. My calculator says that 1/2 D1 should be 360x576/480. How come 1/2 D1 is 353, not 360?

BTW, I'm capturing and burning videos of great quality using official CVD resolution, am only curiouse.

Thanks.

[SatStorm]

We use as base the "other" D1 resolution (the cropped Full D1), which is 704 X 576/480. Read why in the answers of my other article (legal picture resolutions)

Well im writting here because i read some where and i heard you all saying that you cant burn a CVD as a VCD well i am gonna prove you all wrong. here goes my guide

How To Burn CVDS as VCD
First you input these settings on Tmpegenc I use version 2.57 plus I don’t know about you all well anyways this is how……..
First you will do this under the VIDEO tab where it says stream type you will put mpeg 2 video then the size 352*480 then use a 4:3 aspect ratio then 29.97 frames then well the bit rate set it at anything you want but just be careful cause too low will cause crappy video and to high well there ain’t nothing wrong with that only less minutes will fit on the cd. Yes I noticed that I kept on using then and then and then and I am just running on the sentence well I don’t care I am just typing this so back off ok anyways well these are the settings I input for my video bit rate on the frame rate I put MVBR {manual variable bit rate} then next to it is a settings box ok on the max bit rate I used 2,000 and minimum I used 1,500 and I enabled padding not to be lower than 1,500. ok now go to the audio tab on top and on the sampeling frequency put 48000 not 44000 ok now the audio bit rate well its up to you. Then on the tab where it says system change it from what ever it is to a mpeg 1 video cd(non-standard) everything else leave it as it is unless your experienced and know about the gop and the quantize matrix. I am not a newbie nor an expert I have learned the vcd ways and the svcd ways and the xvcd now I wanna move on to something maybe better quality and less bit rate. Anyways I heard that someone said that you cant burn a CVD as a VCD well huh I did it and the way I did it was actually stupid its cause I couldn’t burn it as a svcd and I said well let me try to burn it as a vcd and it worked. Oh and another thing I don’t like to burn movies in svcd the reason is because like yea the audio isn’t out of sync but when I am playing it in my dvd player and I fast forward the audio always messes up and not on the computer so that’s why I hate svcd. And if I would have burned the CVD in svcd I would probably have the same problem so I successfully burned it as a vcd and it came out in really excellent quality and the size was a little bit bigger than vcd and a little bit smaller than svcd but I think the quality was a little bit better than svcd. But remember I used max bit rate at 2,000 kb/s while the bit rate of svcd is 2,520 big difference. Well hey that’s my way of burning a CVD as a vcd and yes it was full screen and no the picture wasn’t cropped or nothing so I would say it works perfect.

You're not burning a CVD as VCD, you're only making a XVCD with the same resolution as a CVD...

hey well i guess i mean what did i do different its not a xvcd you know why cause xvcds are mpeg-1 not 2 i encoded it to mpeg-2 and i put on system MPEG-1 VIDEO CD(non-standard) and it worked.

[SatStorm]

You have created a xVCD.
This is also called "header trick" for those players ain't support mpeg 2 on CDs. It isn't new.

Just for your information: Beyond the mpeg 1/2 issue, CVD use a stracture similar to SVCD's one.
The VCD stracture is totally different. So, putting re-muxxed mpeg 2 as mpeg 1 on a VCD stracture, it is simply a xVCD which it might be playable on some flexible DVD standalones.

quote] hey well damn this sucks i thought i had a cvd burned on a vcd. well if it isnt a cvd what can i do to have it as a cvd. i am kinda new to the cvd but i already know about xvcd and vcd and svcd. but dont direct me to the cvd guide because i read it all and it didnt tell me step by step what to do. so can you tell me what i am missing. well you know in tmpegenc on the project wizard on the top tabs it says system what should i put then MPEG-2 Program or MPEG-2 VBR. i dont know. and another thing when ever i burn an svcd and i fast forward the audio messes up will this happen to cvd if i burn it as a svcd or no plz help me.

[joe444455555]

Need help making CVD display properly
I make it 352x240 all is good
720x480 all is good
352x480 and I have 352x240 with an extra 240 of border when I play on computer.
I want to use the 480 to up the verticle resolution/quality of video I will display on my dvd and not on black border that I will not display. Any advice would be appreciated. I've tried a number of settings (combinations of settings) for source and output aspect ratio (Including a number of Center Custom Size options).
again, thanks for the help (god this is a long chain

[hwoodwar]

joe444455555:

CVD is 352x480 NTSC or 352 x 576 PAL resolution period. Any other resolution and you are not making a CVD. 352x240 is NTSC VCD resolution and 720 x 480 is DVD resolution.

Many programs do not display certain resolutions on your computer properly, but they may be displayed properly on a standalone DVD player. My CVDs look taller than they are wide on the computer, but the display in the proper aspect ratio on my standalone DVD player.

[joe444455555]

Of course, I do understand that. Those were examples of what is should have looked liike, those resolutions produce a correct aspect ratio.
unfortunantly, I cannot get the 352x480 to produce a correct aspect ratio, most of the 480 verticle pixels are wasted. it's about a 16x9 aspect ratio source (Divx, Stargate episode), but the result on my Computer video player is that the aspect is as it should be PLUSS it has a LOT of black at the top and bottom, the window is unrealistically tall, though the image was not stretched or anything.(yes, mpeg2, blah blah blah, I know the settings, just seems no one address the aspect ratio problem I have

I think that the extra resolution is being wasted on the massively tall video shape, most of which is black. Any ideas, or could you help me correct any other misconception I may have
I'm very new to posting, but have tried to do as I have seen (though I did check the entire rest of this thread, and someother shorter threads).

I would think the massive black areas would be filled with double height (vertically stretched it would look like) image, then THAT would be resized on by the DVD player, giving a really crisp 240 pixels on my dinkey TV, but really 480 interlaced (hence the "Really Crisp", since it compressed double the height of encoded video information as is displayed at once)



Edited and added:
I have noticed that if I use mpeg-1 in 352x480 with 4x3 525 line aspect, all is good for apperance, (except, of course, it's mpeg-1, not CVD). It's a full 480 pixels of image, stretched and everything (which is of course good). But if I change to mpeg-2 4x3 (there is no 525 line option, just 4x3 when in mpeg-2 on TMPGenc), I get a 352x240 image with an extra 240 of black space, all wasted.
