AVI two times to big after using Gknot

[JeeWee]

For my KiSS player I want to recode a DiVX3 movie into XviD. For this I try to use GKnot 0.28.7.

I follow the guide for XviD encoding on Gknot and used the settings in this guide. I use the AVI as input and set a target size of 700MB. Compressibility test runs fine.

If I then encode the movie I get an AVI file of around 1600MB. Two times the size i have set.

Does anyone have an idea.

Regards,
Jurgen

Hello, JeeWee, welcome to Doom9's forum!

:logfile: It can help us determine if there was a procedural or setting error of some kind. You'll find it in your working directory under the name <move-name>_Gknot.log.

Thanks!

Uhm... Where is your GK Log-file ??? ;)

PS: Did you compress the audio ??? :rolleyes:

[EDIT: Ohw... jggimi, you are fast !!!]

The requested size is 577536. The actual size after encoding is 1610376kb????

What I see in the log shows that only that you have not selected any audio, nor do you have any AVI frame overhead.

It looks like you are using "Calculate Average Bitrate" mode, and selected selected 564MB as your file size. (Had you selected "Calculate AVI File Size" mode and 861kbps, you would have a slightly different file size.)

Unless someone who can read the API information passed to VirtualDub sees something there untoward, then this looks like this was not a Gknot error, but something in the XviD encoding. Unfortunately, I can't read the information passed to VdbuMod in the API.

If you open your XviD AVI with [url=http://www.doom9.org/Soft21/Editing/gspot221.exe]GSpot[/url,, what does it tell you about the codec, bitrate, and resolution of the resulting file?

And, just in case there's something of interest in the .avs script, could you also post it here for us to look at? You can eliminate all of the comment lines that begin with the "#" character to make it easier to read.

I used a Divx3 encoded file with audio as input file.It looks like you are using "Calculate Average Bitrate" mode, and selected selected 564MB as your file size.That is correct
If you open your XviD AVI with [url=http://www.doom9.org/Soft21/Editing/gspot221.exe]GSpot[/url,, what does it tell you about the codec, bitrate, and resolution of the resulting file?Codec: 4CC=xvid, Name=XviD
bitrate=860kb/s, resolution=512x268
Audio Codec Name=PCM Audio
Audio Bitrate=1536kb/s
And, just in case there's something of interest in the .avs script, could you also post it here for us to look at? You can eliminate all of the comment lines that begin with the "#" character to make it easier to read.avs-file:
LoadPlugin("C:\PROGRA~1\GORDIA~1\mpeg2dec3.dll")

I hope you can tell from these files what I am doing wrong.

Here the problem lies. The problem is due to selecting fullprocessing mode in VirtualDubMode. That is, you might have selected in streams list -> audio streams -> full compression. This in default uses uncompressed wav as sound, increasing your final avi size.:)

[Soulhunter]

As I said before...

Well, I did not use VirtualDub. I used Gknot. I used an AVI file with audio as input file. How can I prevent that Gknot will include the PCM encoded audio. It should use MP3 encoded audio.

[Tuning]

Sorry JeeWee, exact solution is unknown to me bcoz, i never allow GK to mux audio automatically and i had never done avi -> avi encoding with GK.

One solution is to de-mux mp3 from original avi. Then mux the same file again to new avi using VirtualDubMod.

Hope that helps..

[jggimi]

It seems that the audio was included in the AviSynth frameserving process, and AviSynth produces uncompressed video (and audio). Run GSpot again, this time on your original DivX3 source, and let us know what it says about audio codecs.

You can stop the audio from being included in the .avs script by adding the lineKillAudio()to the script (press the Edit button before pressing Save&Encode in the Save AVS window).

If you demux the soundtrack from the source avi, you can then use that soundtrack file in Gknot to calculate proper overheads. Select the file in the Audio A box on the Bitrate tab, select the proper overheads, and then, in the Audio 1 tab when you Save&Encode, selet the file and "just mux."

The audio in this file is 160kb/s CBR MP3.

[jggimi]

I found this at www.avisynth.org:...From v2.04 up there is built-in support for ACM (Audio Compression Manager) audio (e.g. mp3-AVIs).And since you are using AVI as your source, AviSynth is picking up the MP3 audio track and frameserving uncompressed audio to VdubMod. I recommend you either start with a video only .avi source or use KillAudio(), and follow my prior recommendation for encoding and muxing the audio when in Gknot.

I have demuxed the audio from the AVI file using VirtualDub. I then used Gknot and changed the AVS script to include KillAudio(). Encoding now works fine and I obtain the exact size i set on the bitrate page.

It seems my problem is solved. Many thanks for all the help.

You're welcome! Thank you for letting us know the problem is solved.:goodpost:
