Hi all,

Having sorted out my ivtc probs (thanks guys), a new problem seems to have appeared, and I just can't figure out what I am missing here:

After setting up everything for the encode (gknot), on the screen just before the encoding starts, where you configure the audio and video codec. On the AUDIO 1 tab, I tell it to use my .wav file to make the 128k vbr mp3. (The .wav that was created during the dvd2avi step). (Making sure bsweet isn't selected, as it's not ac3 ;)



As soon as I start the job, it barfs out with this message:

04:03:11 AM: IVTC: Re-Calculating Frame Count.
04:03:11 AM: IVTC: FrameRate was 29.970 fps
04:03:11 AM: IVTC: FrameRate now is 23.976 fps
04:03:11 AM: IVTC: 33518 Frames.

04:03:11 AM: Started Transcoding Audio.

04:03:11 AM: Finished. Duration: 0 seconds.

04:03:11 AM: Audio Done.
04:03:11 AM: ERROR: MP3-File-Size is zero! Transcoding failed.
04:03:11 AM: ERROR: Will not recalculate bitrate! - Maybe you can add audio later...
04:03:11 AM: Audio 1, determined: 0 kb
04:03:11 AM: Audio 1, calc: 21843 kb


If I encode this .mp3 manually with Lame and mux it with nandub, it works fine, but I can't understand why gknot is "dropping" this part, claiming the file is 0 size. It doesn't even attempt to transcode the .wav file, but the transcoding never starts! So obviously there is no .mp3 file as output.

Can anyone see anything here that might explain why it's doing this?
Some things I tried: rebooting ;), changing to 160 instead of 128.
Trying to make a complete new d2v file from scratch. etc

As soon as it's "skipped" the audio step, it just goes on with the nandub passes eventually giving further errors at the end when it tried to mux an audio .mp3 that isn't there.

My If there is any other info I can post to help clarify, let me know.

Thanks all

The only thing that comes to my mind is that the lame.exe you've got in Gknot's dir is too old to support --alt-preset?
Then this *will* happen...
Are you using *this* lame when encoding manually?

Hi,

Yeah, the lame I used to encode is the same one as in the gknot folder (V3.92).

Puzzled!
