20fps ?!?

[joecross98]

I've inherited a 20fps AVI file and can't seem to get a compliant VCD out of it. I have no idea how or why it is now 20fps, but I can't get a different copy anywhere.

I've tried TMPGEnc and CCE, but neither supports 20fps.

Is there a way to convert to 24,25 or 30fps without knocking the audio out of whack?

What is the audio frequency, sampling rate, mode (stereo or mono)?

It appears to be Layer 3, 48K, stereo. This is from VirtualDub...

If you first set TMPGEnc's "System" tab to "MPEG1-VideoCD and then load your video, you'll note that under the "Video" tab, it's changed the frame rate to an artificial 60fps.

1) Change that rate to either 24fps or 30fps

2) Change the audio to compliant 44,100Hz

3) Set the resolution to 352x240 (NTSC) or 352x288 (PAL) under both the "Video" and "Advanced" tabs

4) Save your MPEG1-VideoCD-compliant file with a new filename

Let us know of your success ;>}

Actually, this is my main problem - TMPGEnc won't open the file. The message says, "[Filename] can't open or unsupported". I get a similar message with CCE.

VirtualDub can open it and process it, but it warns that changing the frame rate will knock the audio out of synch.

My current thinking is to process the audio and video seperately. Change the frame rate in VirtualDub and the audio in BeSweet. Then put them back together. I've never done this with an AVI (only MPEG) before, so I'm guessing there is a better way.

Any advice?

"Actually, this is my main problem - TMPGEnc won't open the file. The message says, '[Filename] can't open or unsupported'."

It would have saved a lot of time (and effort) if you had mentioned this in your initial post.

Your .AVI file contains a Variable Bot rate (VBR-Mp3 audiostream, which TMPGEnc cannot process.

Do the following to convert .AVIs with VBR-MP3 Audio:

Simply use VirtualDub to save the audio stream as an Uncompressed PCM (WAV) file.
Then set "Video" to "Direct Stream Copying"
Then save the .AVI as a silent .AVI (set "Audio" to "No audio" after you've saved the WAV file).

Then close VirtualDub and restart it
Set "Audio" to "No audio"
Load your silent .AVI
Set "Video" to "Direct Stream Copying"
Under "Audio" click on "WAV Audio" and load your .WAV
Set "Audio" to "Full Processing Mode"
From the "Audio" dropdown menu, select "Compression" and choose the appropriate .MP3 settings. Click on "OK"
From the "File" dropdown menu, select "Save as AVI" and save your file with a new filename.

This method worked great!

I went ahead and re-saved the original with uncompressed audio, just to save some steps, but TMPGEnc is behaving perfectly.

Thanks again!
