Xvid audio

[qpito7]

hey guys,

i had a video file with a Xvid format with a AC3 (0x2000) audio and im encoding it to Vcd.. but when i used VirtualDub P4 to extract its audio it said that i dont have any audio codec to process the AC3...

But Gspot tells that a i had the codec to process it... what do you think can be wrong... i tried to installed another Ac3 codec but still the same result... VirtualDub P4 doesnt recognize any Ac3 codec... it said that i dont have any and it confuse me a lot..

Need all your expertise....

Actually, that version of VirtualDub is telling you that IT is incapable of processing .AC3 audio.

If you're intending to use TMPGEnc for conversion to VCD, trhere's no need to extract and convert the audiostream from your Xvid-compressed .AVI. Just do the following:

In TMPGEnc, under the "Environmental Settings" "VFAPI plugin" tab rightclick on the "Direct Show Multimedia Reader" and increase to the highest priority. This will enable TMPGEnc to accept a properly encoded .AVI with .AC3 audio for input...

ah.. ok, i will try that trick.... thanks set a rip.... for a while you stop my head going round.... hope it will work....

to demigod of digital video:

thanks Set arip it works well...... but i had aonther question if you dont mind. i encode it to 4:3 525 lines NTSC and it produce me a small frame of picture... how can i remove the black space from up and down side of the screen.... is there a way to remove and be in a full screen effect without loosing its quality...... i dont know what the format of the source file.. is there a way to know it.. Gspot tells that its a Xvid file with a AC3 audio... if the source is same size is there a way to enlarge it.... Is TMPGEnc capable of doing that? thanks again............

To create a VCD:

1) Load .AVI file into TMPGEnc
2) Set to "System Video and Audio" (lower right side)
3) Click on "Setting" radio button
4) Click on "System" tab, change mode to "MPEG1-VideoCD" (from default of "MPEG1")
5) Click on "Advanced" tab, change "Video arrange method" to "Center (Custom Size"), change dimensions to 352x288 or 352x240
6) 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
7) 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.
8) Change "Rate Control Mode" to "Automatic VBR (CQ_VBR)" and "Bitrate" to "1,150"
9) Under the "Audio" tab, set to "MPEG-1 Layer II", 44,100 224Kbps
10) Press "Start"


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 ;>}
