AutoGK (avi) sound/other problems

[Deepak]

Hi,

I converted "The Day After Tomorrow" using AutoGK. I am facing a strange problem, the dialogues are almost like whispers but the background noise/sound is normal. This is the log:

I use either my headphone or 2.1 system. Maybe I selected AC3 6ch, that why? Another thing, what is the difference between wide and letbox subtitiles? And which is better, DivX or XviD?

Thanks,

Deepak

Welcome to the forum.

Your audio track was inserted into the final .avi file unchanged. Use AC3Filter to adjust your playback settings for your PC sound system.

The difference between subtitle tracks is the playback position on DVD. For .avi converions, it will make little or no difference which you select.

The difference between XviD and DivX? These are two different MPEG-4 codec implementations -- there are many different MPEG-4 codecs. See Doom9's general descriptions in his MPEG-4 backup guides (http://www.doom9.org/divx-encoding.htm), and for much more information, see his Codec Comparisons (http://www.doom9.org/codec-comparisons.htm).

Thanks, it is better now. But still I am having to set volume to max to hear it. Maybe I didn't change AC3filter settings correctly?

Am I correct in assuming that audio won't be audible without installing AC3Filter (if I copy it on any other PC) and the file won't play without XviD codec? Was I right in opting for AC3 6ch sound which converting?

[jggimi]

You could try setting the AC3Filter Preset to "loud" -- see if that helps. For more information on configuring AC3Filter, please read the included documentation.

You are correct that AC3Filter is needed if a commercial Dolby Digital decoder is not installed. You are also correct that an MPEG-4 ASP decoder is also needed for playback. This can be XviD, ffdshow, or others that support XviD playback.

Were you right to use a DD 5.1ch soundtrack? I cannot answer that question, based on what little I know so far. Since your included log shows a quality-based encode, I do not know if file size is of any value to you or not. Here's what I do know: Your content has 177914 frames. At 23.976fps, this is 7421 seconds (123:41). DD 5.1ch soundtracks are typically either 384 or 448 kbps. Your 5.1ch soundtrack will consume 340 or 396 MB of space for that length of time. If a DD 2.1ch or DD2.0ch soundtrack is available on this DVD, it is possible that it may have a better stereo downmix than AC3Filter will produce. They are typically 192kpbs, and would only consume 170MB for that length of time. A 128kbps MP3 soundtrack, if you decided to convert to an MP3 with that average bitrate, will only consume 113MB.For more on audio, please see our Audio Encoding forum -- questions of this nature are better handled there.

seems evrything i try i get nothing but an audio sync problem cant get any tool to work now without this problem AGK is out of sync what do i need to look for

[CWR03]

Deepak, when you open your AC3 Filter controls click the Mixer tab - there is a slider bar for Voice that you can adjust individually, as well as auto gain controls that you can disable, which together should solve your problem.

As far as playing them back on other computers, yes, you'll need AC3 Filter and XviD installed on it - they're not basic components of Windows. Personally I recommend the GordianKnot codec pack, AC3 Filter, XviD and ffdshow installed, at which point you'll be able to play any file you can lay your hands on.

Nrmf, there are already many, many threads on audio synch, including one you've already started, that deal with your specific problem.

Thanks CWR03, its works fine now. And thanks jggimi. Great!

The folder where I stored the converted avi also has one agk_tmp folder, can I delete it and other files except the avi?
