Quick qns about VirtualDub and its variants

[ramian]

I currently use VirtualDub and VirtualDub MP3 Freeze concurrently for my various AVI/VBR MP3 editing needs. I however have VirtualDubMod around because I also use Avi.NET. I do understand the additional features that are available in VirtualDubMod, so there's no need to list them again.

My first question is whether VirtualDubMod can handle VBR MP3 without affecting sync. All my dealings with AVIs with VBR MP3 are only to trim/split/join (using direct stream copy) and thus I don't bother re-encoding the audio to CBR MP3. So, I use VirtualDub MP3 Freeze to work with such AVIs. Thus far, I've avoided using VirtualDubMod for such VBR MP3 AVIs because of the dialog box which pops up when I open such an avi file in the program. If I click "No", would VirtualDubMod be able to handle the VBR MP3 (to only trim/split/join AVIs) without causing it to go out of sync? I know for a fact that VirtualDub MP3 Freeze processes VBR MP3 using direct stream copy without affecting A-V sync. If VirtualDubMod was also capable of doing this, I could just ditch VirtualDub MP3 Freeze and stick with VirtualDubMod.

My second question is whether VirtualDub has any additional benefit whatsoever compared to VirtualDubMod. Is there anything that VirtualDub can do that VirtualDubMod cannot do? I have been using VirtualDub for a number of years already and have become comfortable with it. While VirtualDubMod is currently not as easy to use (for me at least), I'd be willing to switch over from VirtualDub if I won't lose out on anything (even something new I may potentially want to do in the future) by using VirtualDubMod over VirtualDub.

Thanks!

Hi-

My first question is whether VirtualDubMod can handle VBR MP3 without affecting sync.

Yes.

If I click "No", would VirtualDubMod be able to handle the VBR MP3 (to only trim/split/join AVIs) without causing it to go out of sync?

Yes.

Now, if there's a delay you don't know about, and you don't give it the same delay when splitting, they'll become out of synch. When you join 2 AVIs and the audio of Part 1 is shorter than the video of Part 1, then you'll get the 2nd part out of synch. But I've worked with 1000s of AVIs in VDubMod over the years, all my own creations, almost all with VBR MP3 (except for the AC3 ones), with nary a problem muxing, demuxing, cutting, joining, etc.

My second question is whether VirtualDub has any additional benefit whatsoever compared to VirtualDubMod.

I couldn't tell you, as all I use is VDubMod, and it does everything I want.

The newest VD, 1.6, can reportedly handle DV Type 1 files and transfer Type 2 from a camcorder, and may be able to handle some VBR audio like MP3 Freeze, though I haven't tried any of these options. The older VD has a problem with these. There are also a bunch of other tweaks.

I mostly use VD Mod for working with AVIs and converting an occasional MPEG to Xvid format. It will accept VOB files directly, also. VD Mod is built on the 1.5 version of VD. I like VDM's arrangement for handling audio better than the regular VD. I use VDM most of the time. If I deal with VBR audio, it's usually for conversion to DVD format, so I save it out as a WAV anyway and use ffmpeggui to convert to AC3. I've never used MP3 Freeze.

Thanks for all your replies.
Looks like I'll just stick to using VirtualDubMod.

@redwudz,
I capture in DV Type 2 using WinDV and so am not worried that VirtualDubMod can't capture in that format. But can it accept Type 2 DV files at all? (I would try it out myself, but don't have any available footage on the computer to try out, or time to record new ones.) Otherwise, if there's nothing mission-critical, I guess I'll be sticking with VirtualDubMod.

Also, is there any news about VirtualDubMod being updated to VirtualDub 1.6? The last update was in Feb this year.

Thanks!

If you are asking can VDM accept a DV Type-2 file that is on your hard drive, yes. That's how I process all my DV files. You need to add the Panasonic DV Codec, or similar, though. I edit and filter as needed, then frameserve the output directly to TMPGEnc encoder. This avoids having to store the extra edited file on the hard drive. You can also save AVI files to DV format, as long as they are the same framesize as DV. This is handy for frame accurate editing sometimes.

I haven't got around to trying VD 1.6 for transfers from a DV device, maybe tomorrow, if I get a chance.

Outside of a few bugfixes, there hasn't been much development lately for VDM.

Thanks for the quick reply redwudz.
I already am using the Panasonic DV codec. I should have guessed that VirtualDubMod thus indeed support Type 2 DV files given that it was based on VirtualDub 1.5 which I knew supported it.
You mentioned frameserving output from VirtualDubMod to TMPGEnc. I'm not really all that good with AviSynth scripts, so is there a guide available?

Thanks!

[manono]

I don't think he's using AviSynth, although he should be. For all the AviSynth info you'll need, read and learn everything here:

http://www.avisynth.org/

[ramian]

I think this guide: https://forum.videohelp.com/viewtopic.php?t=222898 will get me through the basics. If I need more advanced scripting, I'll probably dig through the link you gave above.

Thanks once again!

Edit: it is going quite OT, so I'll stop asking frameserving questions here. Sorry.

My second question is whether VirtualDub has any additional benefit whatsoever compared to VirtualDubMod.

VirtualDubMod will crash and die if you try to view the properties (File -> File Information) of an AVI that doesn't have audio.

Not in my case.

Oops, sorry, I remembered incorrectly. It crashes when you load an MPEG file with no audio (M2V).

I have 1.5.10.2, the one linked from this site. I found and downloaded 1.5.4.1 and it doesn't crash under the same circumstances.

[lordsmurf]

No problem here either, using 1.5.1, loads M2V fine.

[ramian]

In that case, there isn't really any additional benefit of having VirtualDub around right?

VirtualDub continues to evolve. VirtualDubMod hasn't been updated in years.
