VirtualDub Output question...

[nharikrishna]

I have a very highly grainy VHS Video that I captured as DV AVI format using Canopus ADVC 110. So the size is 13 GB/1 Hr.

After capturing, I loaded the NeatVideo Filter in VirtualDub, and then when I saved the "filtered" video (by chosing "Save as AVI" in VirtualDub), the output video is coming out 2 GB per 1 minute of video!

My intention is to get the same DV AVI back (13GB/1 Hr) after filteration.

How do I achieve that in VirtualDub? I am sure I am missing some output setting here but not sure which one. The "Compression" option in VirtualDub doesn't contain anything like "DV AVI"...

Regards

install cedocida

select video=>compression=>cedocida , before you use file=>save as avi

OK thanks. I will try that...but I have a few further questions...

1. I use Premiere Pro for editing and since Premiere uses mainConcept DV codec, why is the same not listed under available codes in VirtualDub? (I am interested in this as I read somewhere that MainConcept DV codec is very good and is better than some others)

2. Windows would have come with Microsoft's DV codec. Why is this not listed under VirtualDub either?

3. Is there a way I can find out what DV codec is used by my Panasonic MiniDV Camcorder while 'shooting the video'? Even if I can find out, is it useful to know it?

4. Is any DV codec coming into play while capturing from my MiniDV Camcorder through Firewire cable into my computer from the programs WinDV or Premiere Pro? or the codec comes into picture only at the time of "exporting" to the final AVI after edits (if export to DV AVI is the option I choose from PPro)?

Thanks.

I have no reason to believe MC DV codec is any better than Cedocida. And you have no choice when using VirtualDub anyway.

There are two video subsystems under Windows: VFW and DirectShow. Each uses different codecs. VFW programs cannot access DirectShow codecs, and vice versa. Windows does not come with a VFW DV codec, only a DirectShow decoder. If you are using 64 bit Windows there is the further complication of there being separate 32 bit and 64 bit subsystems. Each with their own VFW and DirectShow codecs. 32 bit programs cannont access 64 bit codecs and vice versa. In this case you have four separate video subsystems. If you use XP Mode that adds two more, for six separate video subsystems, all of which cannot access each others codecs.

Your camcorder has a built in hardware DV encoder and decoder chip.

When done properly, capturing DV via firewire does not involve and DV codec going from the port to the file. But most programs also display the video while it's being captured. A DirectShow DV decoder is usually used for that. What's going into the DV AVI file is still the original compressed DV data from the camcorder.

What about the OP's other question:

1. I use Premiere Pro for editing and since Premiere uses mainConcept DV codec, why is the same not listed under available codes in VirtualDub?

According to the link to the Tools section, MainConcept DV Codec is a VfW codec.
Why doesn't it show up as available in VirtualDub?
(Perhaps Premiere Pro uses it directly, rather than installing it for anything to use?)

I think Premiere uses private dlls, not system installed codecs (although it can also access installed VFW codecs). That gives them better control over version compatibility issues.

That's excellent. Thanks a lot for the clarifications.

neat video comes available as a plugin for premiere pro as well, it might simplify your workflow - unless you're doing something else in vdub that can't be done in premiere?

Yes, I thought so too...Will try VDub in PPro. Thanks.
