Xvid to Vcd how do i .....

[crckdice]

Ok, so i'm a total newb to encoding and recoding and so on and so on, and last week i found a great article that linked to Digital Digest about DivX to VCD and it worked Great however, now i have an Xvid i need to switch over. From the few posts i've seen i guess u need all the info from virtualdub before being able to help so here it is.

Video Stream
Frame size: 576*320, 23.976 fps
Length :144432 frames 1:40:24:02
Decompressor : XviD MPEG-4 Codec
Number of Key Frames : 1750
Min/avg/max/total key frame size : 2014/11687/49527 (19974k)
Min/avg/max/total delta frame size : 103/4145/28029 (577583K)
Data Rate : 813 kbps (0.56% overhead)

Audio Stream
Sampling Rate : 48000Hz
Channels : 2(stereo)
Sample Precision : N/A
Compression : Fraunhofer IIS MPEG layer-3 Codec
Layout : 250996 chunks (0.02s preload)
length : 104403168 samples (1:40:24:07)
Min/avg/max/total frame size : 96/415/480 (101957K)
Data Rate : 139 kbps (5.46% overhead)

And that's all she wrote so hope someone can help TIA

Unless the MP3 audio is VBR, you can use TMPGEnc to encode and nero to burn. check out these nice guides http://dvdrhelp.com/tmpgenc

Thanks worked great altho my audio is couple milliseconds off but great otherwise thanks for the help

A few things you'll have to do, prior to using TMPGEnc to convert this file:

A) (If not yet done) Download and install an Xvid codec

B) (If not yet done) Download and install the FFDShow filter (and set it to be responsible for XviD playback

C) Based on the information you've posted (It's refreshing to come across someone who actually reads and follows prviously posted information!), your file's audiostream IS, in fact, a Variable Bitrate (VBR) .MP3 audiostream. (As David should know by now, if it was in Constant Bitrate [CBR], the number of audio "chunks [frames] would be almost identical to the number of video frames. VBR streams typically have up to twice as many frames as the videostream.) Therefore, do the the following to convert your Xvid-compressed .AVI with VBR-MP3 Audio for use with TMPGEnc:

Simply use NanDub (or VirtualDubMod) to save the audio stream as an Uncompressed PCM (WAV) file as follows:
Load your original .AVI into NanDub
Set "Video" to "Direct Stream Copy"
Set "Audio" to "Full Processing Mode"
From the "Audio" dropdown menu, select "Compression" and choose - and choose "No compression(PCM)"
From the "File" dropdown menu, select "Save WAV" (Enter a new filename with a ".WAV" extender).Click on "OK"
Then save the .AVI as a silent .AVI (set "Audio" to "No audio" after you've saved the WAV file).
Open TMPGEnc and FIRST "drag and drop" the silent .AVI onto it, then do the same with the .WAV file.

Let us know of your success ;>}

I still don't get why you should save the silent avi. Basically you haven't changed the video stream, the cmopression is still the same as it was before right? I just load the old video into TMPGenc and select a the brand new wav file for the audio. This works fine with me...

[shiny#3]

you are right mosthated.

but if you load a non silent stream into Tmpeg it chooses
the wrapped in audiostream by default.

a total newbie might think all is set up fine and I guess
when suggesting the mentioned method setarip just wants to
make sure to rule out all misleading possibilities.

I couldn't have said it better myself ;>}

[shiny#3]

on top of that... having hardware space problems
the mentioned method is good since it denies keeping the wav.

it might also be the fact that people fall for the temptation to
change the audiostream simply to wav with the new virtualdub mod. and then end up with an avi bigger than 2GB

just for the purpose of having dealt with all of likely problems

[Stained_Black]

As i'm in the same situation (newbie status), i've followed the instruction setarip has given us... up to the point where you save the silent avi. Using Virtualdub, I've added a filter to adjust the brightness/contrast. It prompts me with this: "Filters cannot be used if the video mode is set to Full Processing Mode"

How do i get around this issue?

EDIT: I should add that if i change the video mode to Full Processing Mode, the estimated size of the avi file is ridiculously huge... i think it said something like 68gb lol

[shiny#3]

changeing brighness and color settings of a video require the
full processing mode in the video dropdown menue.

using this mode you will have to choose a compression.
best is that you find out what codec has been used compressing your video with the fileinformation option in filedropdown menue
then use this codec and set it to approximatly the same bitrate
in the configuration window after you have chosen your codec.

(it says "configure" on the right hand side after you selected
the codec from the codeclist)!

Thanks for that shiny. I burnt off a copy of the movie, after converting the xvid avi to VCD (Pal). When i watch it on the tv, the video looks fine though it isn't smooth or flowing. It's hard to explain, but it kinda jumps every second or two. Should i try converting it to NTSC instead?

[shiny#3]

I guess the main issue on creating a VCD is that you can play it
on your standalone. make sure that your standalone is able
to display a ntsc vcd. if so do not change framerates and do
not do any ntsc pal conversion.

if the problem persists
download the newest xvid codec to decode your xvid and disable
the ffdshow filter. or since you do a reencode to avi to adjust brighness , anyway use a compatible codec like Divx pro.

in addition to that do also a downsampling from 48.000
to 44.100 khz in Tmpeg
