Recently updated to program version 1.10.4 and hoped that movies with ac3 sound (stereo or 5.1) would be handled by the program. What can I say: It's worse than ever.
Any Movie containing a AC3 sound stream isn't handled correctly anymore. Even when the codec list shows, that AC3 is available, it doesn't mean, that this include a conversion, too. The program simply claims "the codec necessary for this conversion is not installed" ... how did it appear in the program's own list?
Pushing it to the limit: Asked the program to copy the sound stream from the original MP4-file and got the information from the program "VirtualDub Error: The file .....MP4 does not contain an audio track". No need to say, all other programs can play the file WITH SOUND and Mediainfo shows a perfectly available AC3 5.1 audio stream.
Even better: Did a test with an TS-Video file and - surprise - it was accepted by the import filter (also updated). All streams were shown correctly in the file information screen. Because of the a.m. problem I tried to copy an audio stream from the original file (no editing were necessary anyway): VirtualDub did the job, but what was the output? The Video codec was correctly converted to Xvid, the audio stream WAS NOT COPIED, but converted from AC3 5.1 to PCM 2.0.
If these bugs are caused by VirtualDub or the AC3 audio filter it's hard to say for the user. But as a matter of fact: For AC3 I am going to use something else in the future. |

Would have been more useful to mention what plugins and codecs you're using, mind reading is never a good way to solve problems and doesn't encourage anyone to help
But, here's some test info for you anyway
mp4 source, h264 video, ac3 5.1 audio
open with quicktime plugin, save in direct stream copy mode - fine (needs an acm ac3 codec installed, I use ffhandlers one in my sig)
directshow and ffmpeg plugins - don't need testing, as they deliver decompressed data to virtualdub, so direct stream copying would be useless anyway

Fcchandlers aac-acm decoder properties sometimes will show some encoder values although they are disabled for encoding use. With Fcchandlers acc-acm source code available having aac-acm encoding with Virtualdub and more would be useful for everyone |

Having fcchandlers ac3 stuff built into virtualdub would be up to Phaeron. And with fcchandler being unreachable, there's no way to get permission to do that.

sorry - just forgot to mention this things..
VirtualDub v 1.10.4
AC3 ACM codec v2.2 by fccHandler
AC3 ACM Extensible v 2.2 by fccHandler
AC3Filter 2.6.0b by Alexander Vigorsky
ffdshow_rev4530_20140209
ffmpeg-20140215
no further plugins installed
After your answer I installed now Quicktime plugin - but nothing has changed.
It's a surprise that some movies running correctly, means video conversion runs and the audio stream is copied correctly. The next movie recorded from the same sat receiver is running without any audio stream. Both input files contains a MP4-format with AC3 5.1.
How that? Why is VirtualDub not accepting the audio stream at all? ffmpeg was updated especially for MP4 and ts imports. As far I can see this works better than in the past.
And for your second question: I thought this is simply a forum for bug informations - I didn't expect any help, sorry again when this was wrong. |

File > Open Video File
Choose your video
Files Of Type > Quicktime Time Files
If still have problem after trying the above with Files Of Type > Quicktime Files and also FFmpeg if Quicktime has problems (FFmpeg plugin will need audio re-encoded otherwise it will save as PCM using Direct Copy)
If neither of the above work, maybe the audio has a problem in your video. You could test and verify this by the following...
File > File Information look at Audio Stream details noting the Sample Rate and Data Rate. Also confirm if it is 16bit and has 5.1 channels
Audio > select 'Full Processing Mode'
Audio > Compression
AC-3 ACM Extensible
Select same Sample Rate, Data Rate and channels of the audio as noted from File > File Information 'Audio Stream' (as mentioned above)
Video > Direct Copy
Save the video as avi after play the video to hear if audio is there. There after Virtualdub will be ok to use with Audio > Direct Copy no further audio encoding required |

There's quite a few who'll try and help out, but sometimes it is easier to use another tool when your having problems with a certain filetype/plugin
FccHandlers plugins etc are good, but he vanished quite a while ago and no further development has happened since
It can be something as simple as the way the files muxed that's causing problems - I'll use ffmpeg to remux or transcode to a different container and that can solve some problems
Trying different plugins can help, but about 50% do the decompressing themselves and deliver that to virtaldub so they're no help if you just want to do direct stream copying
As to your first point about virtualdub getting worse at coping, well it seems to be more like virtualdub hasn't really changed but there are more badly created files out there and they're causing more of a problem with virtualdub than they used to
Extra programmers would help but they're in short supply when they're not getting paid ;-)

Sorry for late reply. Thanks it worked, but....
Either the plugin isn't working correctly, or VirtualDub is doing some convertions without instructions.
check this out:
As you can see, I've imported an mp4.-movie (full hd, ac3 5.1 sound). The file properties window of VirtualDub is showing me strange data after importing. Without any given instructions the frame rate is changed from 25 to 50, the sound stream is called "5 channels" instead of existing 6 (or 5.1).
Is this already known (i couldn't find anything in the forum)? |

Not sure about the fps, does the 50fps one have duplicated frames?
Or, could be one is reporting 50i and the other 25p?
Same for the audio, 5.1 could be reported as 5, 5.1 or 6 - it all depends on who wrote the code deciding on how they wanted it displayed
So I'm not sure these are actual problems or just differences in the programs display information
You could test by loading into virtualdub, saving in direct stream copy mode and then comparing both with mediainfo
ps
better free img host that allows unresized images

On MediaInfo change the view to show as Text
Wondering Microsoft MP42 could be part of the problem though those codecs will be on every system since XP and newer
Found an mp4 file that has a fourcc MP42. Maybe yours is similar that the fps maximum is 50 and the minimum fps is 25. Would need to change MediaInfo view to know
When select the above image and when it shows larger, select the image again to make the writing more visible
Is there a better free image upload site that does it better such as web links so have same size images as uploaded on forums ? |

Couldn't say about image hosting - imageshack used to be good, but now is useless
This was just the first free one I found that allowed non-resized images
Looks like you can just add \full\ to that url to get the 100% view, but that may break the link if they change in the future as it isn't official
| QUOTE | | bitrate maximum is 50 and the minimum bitrate is 25 |
Did you typo fps, not bitrate?
Fps is an odd thing with variable frame rate files, it can be set as 25 in the container header, but vary wildly through the video
So there are 4 possible 'correct' values you could report - the headers fps, real minimum, real maximum and the real average
(Sigh, I miss the old avi days when it was just frame 1,2,3 etc)

here we go:
I had to use another recorded movie, since the old sources were gone already...
Funny stuff, because the new one now is showing up in VirtualDub Quicktime Import with 25 fps (instead of 50 fps before).
I repeat here the whole process and include pics (posted at Postimg.Org!) as requested:
At first you can see the source data how they appear in MediaInfo and by using the QuickTime Import plugin for a HD movie
Again - the wrong "5-channel-" audio remark... and in opposite of the assumption, that this is only a display error: I'll get only the following options for audio conversions - all 5 channels only!
To make the difference clear, here the import result, using the "FFMPEG compatible filter" instead of "QuickTime" for the same movie. Surprise, it shows up correctly with 6 channels
Consequentely VirtualDub offers me now in available codecs 6 channels, too.
Unfortunately the program drives you nuts from here on:
The import shows you 6 channels, available compression codecs gives you 6 (better 5.1) channels and still... and it won't matter if you take the same data in audio as imported.
As said before: I choosed "Direct Copy" for the audio stream instead - and it worked!
But you can be never sure about it. The next conversion a 720p HD movie, the same proceedings led to a "direct copy" output of 6 Channel PCM. I had to use "Xmedia Recode" instead to get it right.
You want to feel like someone is playing a joke on you, try the same with SD. The QuickTime Import plugin opens this movie like this
and just to show you, that there is no difference but the frame size
That's it for today. |

Audio Menu > Full Processing Compression > No Compression (PCM) > OK
File Menu > Save WAV
Audio Menu > Audio From Another File > Load the WAV.. file you have just saved
Now the audio should be 5.1 and is the only audio track for the video
Audio Menu > Compression > AC3 > Set 5.1 channels using the same bitrate as the original audio (448 kBit/s)
Video Menu > Direct Copy
File Menu > Save video as AVI
After save the video can load video avi as normal or drag and drop on to virtualdub to load |
