SVCD size on NERO6

[woodyalien]

I'm trying to burn a 688Mb AVI file into a SVCD using Nero.

Nero shows on size bar that he can fit the video on a 80 min CD but, actually, it CAN'T: after 3-4 hours of encoding process it issues a message that CD does not have enough space!

I've found the temporary file for burning: a little more than 1Gb!

Does anybody experienced this before?
How to correct handle its size?

[crazyman]

don;t use nero to encode avi files use tmpgenc and use it's unlock feature to adjust the bitrate to make a xvcd or xsvcd so it will fir on one disc.

[woodyalien]

I've found another kind of mismatch on TMPGEnc:
It calculates well the final file size, 732Mb, but makes no sense once it shows as occupying 93% of a 80 min disc... afaik 80 min cds can accommodate only 702Mb!

I should be wrong... Nero and TMPGEnc against me!
What's the logic for that?

[crazyman]

it calculates the percentage by how long the movie is so that 732meg vcd will fit on one disc.

[woodyalien]

well, crazyman... seems to me as a crazy concept but Ill try anyway...
btw, should this generated MPEG has audible audio on PC?
(my one has no sound but I can see on VirtualDub there is an audio stream there)

[crazyman]

if it ends up with no audio it must be ac3 which you will need to convert to wave.

[crazyman]

how long is the file anyway?I mean by time though.

[woodyalien]

it's Lame MP3 audio on Divx3 AVI
time: 55:29

[crazyman]

also if it still doesn't fit then use tmpgenc and make an xvcd so you can change the bitrate to fit one cd,use bitrate calculator to get the bitrate and then use tmpg's unlock feature to do it.

Your .AVI file contains a Variable Bitrate (VBR) .MP3, which TMPGEnc is unable to process. Therefore, in order to convert VBR-MP3 Audio for use with TMPGEnc (and then create a compliant VideoCD file):

Simply use NanDub or VirtualDubMOD (Different than standard VirtualDub), to save the audio stream as an Uncompressed PCM (WAV) file as follows:
1) Load your original .AVI into NanDub

2)Set "Video" to "Direct Stream Copy"

3) Set "Audio" to "Full Processing Mode" (NanDub only -For VirtualDubMOD>"Streams>"Stream list">>rightclick on the listed audiostream and then select "Full Processing Mode")
From the "Audio" dropdown menu, select "Compression" and choose "No compression(PCM)" (NanDub only - For VirtualDubMOD>"Streams>"Stream list">>rightclick on the listed audiostream and then select "Compression" and choose "No compression(PCM)")

4) From the "File" dropdown menu, select "Save WAV" (In VIrtualDubMOD, "Save WAV" is located under the "Streams" drodpown menu) (Enter a new filename with a ".WAV" extender).Click on "OK"

5) Then save the .AVI as a silent .AVI (NanDub - set "Audio" to "No audio" after you've saved the WAV file. - For VirtualDubMOD>"Streams>"Stream list">>click on the listed audiostream and then select "Disable").

6) Open TMPGEnc and FIRST "drag and drop" the silent .AVI onto it, then do the same with the .WAV file.

7) Set to "System Video and Audio" (lower right side)
8) Click on "Setting" radio button
9) Click on "System" tab, change mode to "MPEG1-VideoCD" (from default of "MPEG1")
10) Click on "Advanced" tab, change "Video arrange method" to "Center (Custom Size"), change dimensions to 352x288 or 352x240
11) Change "Source aspect ratio" to either "4:3 525 line (NTSC 704x480)", "4:3 525 line (NTSC)", or "16:9 525 line (NTSC)" - If you're in the PAL world choose either of the two similar PAL settings instead
12) Under the "Video" tab, change the dimensions to 352x288 or 352x240 (Note: "Video" tab mode of "MPEG1" is okay) - set "Motion Search Precision" to "Normal Quality". Change the "Aspect Ratio" to match, as closely as possible, the "Source Aspect Ratio" you set under the "Advanced" tab.
13) Change "Rate Control Mode" to "Automatic VBR (CQ_VBR)" and "Bitrate" to "1,150"
14) Under the "Audio" tab, set to 44,100 224Kbps
15) Press "Start"

(Or, instead of the steps 7)-15) above, you could attempt to use TMPGEnc's VCD "wizard"/template)

Note that if your video runs longer than 70-80 minutes, you'll have to subsequently split your VCD-MPG file in two. This too can be easily and precisely accomplished using TMPGEnc. Under the "Files" dropdown menu, click on "MPEG Tools" and select the "Merge & Cut" tab. Once again, make sure to change the mode to "MPEG1-Video CD". Load your file and enter a new (.MPG) name in the "Output file" box. Then doubleclick on the ORIGINAL file's name in the window, which will bring you to the cutting area. Select your desired start and end points for the first half, click on "Okay" which will bring you back to the first window and generate (in a sequence of three automated steps) the first new file. To create the second new file, repeat the steps starting with "Then doubleclick on the ORIGINAL..." (be extra patient with the second half, as the program has to do more seeking to establish the beginning of the new file).

Use a burning program, such as NERO to burn your CD-R or R/W CD as a VCD (DON'T ask NERO to format the file as a VCD, since you've already accomplished this!)

Let us know of your success ;>}

[woodyalien]

wow! I should need a week to do that! [lol]

@setarip: VirtualDubMod doesn't accuse this video as a VBR as it accuses other videos I have... whatever, I'm going to do that... makes sense reencoding the audio to make sure!

[woodyalien]

when trying to save the WAV from AVI file using VirtualDubMod:
"error initializing audio stream decompression: the requested conversion is not possible. check to make sure you have the required codec"

I think I have the needed codec once it's possible to play it video+audio...

(using BeSweet on its place...)

in addition to that and to make things even more complicated
I want to add that nero is able to burn a 820mb file of mpeg2
formatted data to a normal 700mb disc when using SVCD mode!!
this post is adressing all but setarip,.... and especially woodyalien
the tracks and pit and lands of a SVCD can be put closer together
gaining more data storage capacity out of the same DYE...


good luck

[woodyalien]

it's pretty amazing!!!
thanks for adding, shiny#3... and also complicating! ^^

[shiny#3]

ok......to be of any sufficient help , it would be good to know more
information of your avifile.....can you please get yourself "Gspot"
check it with gspot (by loading it into it ) and post here ANYTHING
it sais, or better do a screenshot??????

Gspot is available here
