Question about DV codecs relationshiop to AVI type, Vid For |
|
|
Trying to sort out various issues related to DV codecs.
I'm capturing with Pinnacle Studio 9. According to input I've gotten on the
Pinnacle forums, it's based on Directshow and only produces Type 2 DV avi
However, from what I've been able to divine, both the $49 Mainconcept DV
codec and (freebie) Panasonic DV codecs are designed for Video For WIndows.
So, why does DV captured on PS9 show the Panasonic codec or Mainconcept
Codec (whichever is installed) under file properties? Further, when
processing with Virtualdub, they're shown in the compression codecs list.
But if they're based on Video For WIndows, why do they even work with DV
video that was processed on an app that's based on Directshow?
Further, assuming my initial premises are correct (and if they're not,
please straighten me out), is there a DV codec that's designed for
Directshow that can be installed so I can process in Virtualdub, still edit
with PS9 and stay within the DV realm? Apparently whatever DV codec that PS9
uses isn't available to Virtualdub.
Thanks for all shared wisdom

Are you making an assumptive leap that Pinnacle 9 is an app that lives
only in the directshow world and therefore anything in and out is
incompatible with other apps? Pinnacle should just be capturing standard
Type II DV Avi's, and those files should be usable by any app that can
import Type II DV Avi's.
Perhaps you should illuminate more the steps you are taking and exactly
where its all going wrong. It seems you care capturing with Pinnacle, do
some processing step with Virtualdub and then wanting to edit some more
in Pinnacle.
There should be no specific reason that different, stable, codecs cannot
live happily on your computer. |

DirectShow apps are Video for Windows aware and Microsoft provides a
"wrapper" to allow VfW codecs to appear as DS ones.
The reverse ain't so!

Well, that's definitely one of the things that I'm trying to understand.

Yes, that's correct.
Ultimately, where it's going wrong is this out of sync audio I'm getting
when capturing to DV avi via passthrough from a VCR through a Sony Dig8
camcorder. As I outlined in a different thread, it didn't do this until I
did a clean reinstall of XP Home. Same machine, same sound card (Audigy2)
same Pinnacle PS9. Worked fine before, now it doesn't. Doesn't happen when
capturing mjpeg, just DV.
Now that I'm focusing on these issues, I've found more things that I don't
fully understand. |

Okay, that clears some things up. Given this, is there such a thing as a
Directshow DV codec? In particular, one that Virtualdub will recognize?
| Quote: | (Did you successfully uninstall the MainConcept codec?)

Yes. As it turns out, when installing the MC codec, it puts an uninstall
utility right in the start>programs menu. Uninstalling the Panasonic codec
was more involved. You have to go into the registry, simply removing it from
the codecs list doesn't get rid of it. |

A DirectShow DV codec comes with the OS but it isn't the best quality in the
world, hence why third parties offer alternatives. As far as Virtualdub
goes, I don't know - my limited (dangerous) knowledge of it tells me its a
Video for Windows app.

It sounds like you are trying to find a codec that will eradicate your sync |
problem. I don't think that will help. The problem seems to be more rooted
in the Type II vs. Type I issue. You state elsewhere that you did a clean
install - did you change any of the hard drive configurations and/or any
other hardware? If you have you OS, apps and video files on the same drive,
it *may* be that the physical layout of where the various bits are has
changed and the drive heads have to travel further at getting at the
separate parts of the file (or something like that).
Also, is your reinstall of XP the same as previous as far as service packs
and updates go? Are there any background programs running -
antivirus/spyware etc - that weren't previously?

Pinnicle has a small utility on their website that does something with the
PCI bus timing that you may find helps. It is called the PCI Performance
Enhancer.
I have found that with the same machine and a different build I have needed
it then not. Give it a whirl.

Try using the demo of Scenealyzer to capture and see if the same things
happens. It may just be the Pinnacle capture program.
http://www.scenalyzer.com/
The demo is fully functional. |

Ok, the way I understood it, in a simple firewire capture from the
camcorder, the codecs are not doing their magic. Its only after you
caputure and then have some specific command issued, such as "Render As"
that the codecs get into the act.
If your pass through captures are getting unsynced, it's probably not
your codecs that are doing the damage. Its somewhere else along the line.
Just as an odd question however, if your sound is unsynced, could you
possibly just move the audio track on the timeline until it is in sync?
Or is that not realistic in your situation. |

The C: drive that has the O/S and apps is now NTFS, before it was FAT32. The
separate capture drive was NTFS before and still is. Otherwise, I don't
believe anything else is different however, segueing into your other
question:

Not sure as to the updates - got the machine with XP installed.off ebay with
no discs, so it was sort of an ahem.... *cough cough*....not altogether
legitimate copy that the seller installed before shipping. Not sure if they
did any updates or not. However, now I'm running fully legal.

No, I'm using a dedicated 120 gig 7200 rpm drive. Same one as before. |

As a follow up, I just got word back from Mainconcept that their DV codec is
both Directshow and VFW. |
