Frage von Gimbly:
Hello,
I'd like of my DV camcorder (Panasonic NV-GS280) with VirtualDub (under Win XP) to capture and compress with HuffYUV 2.1.1. The codec is installed and synonymous in the capture mode in VirtualDub Video / Compression selectablly.
If I but under Device "USB Video Device (Direct Show)" option, I was the only choice under Video / Compression Only "(No compression: dvsd)".
What should I do so I HuffYUV or other codecs synonymous choose?
Antwort von Andreas_Kiel:
Why do you want to capture the already compressed?
Antwort von Gimbly:
Due to memory requirements. Since HuffYUV lossless compression, this is so synonymous totally harmless.
Antwort von Quadruplex:
It is completely nonsensical, which data has already reduced IR signal with a loss-free codec to convert - disk space costs only and will Nullkommanix.
HuffYUV is' ne fine thing - but only interesting if you already videos (such as effects, etc.) must unpack. Then it bypasses with a loss-free codec possibly several new DV intermediate stages - whose errors can be added. But, as I said: Only the dubbing is HuffYUV fail s.Platze - DV DV as it throws to the plate - fettisch!
Edit: See just now that the initial question of the speech was USB. Supposedly it with current Panasonic camcorders indeed possible, synonymous computer via USB to transfer. Per Firewire is stress-free but ...
Antwort von Gimbly:
Is it absolutely no preference, with whatever codec you do?
Edit: I use USB, because my office computer has no FireWire. It works generally synonymous, but I can not select another codec. At home I tried it with FireWire, but was the same.
Antwort von Quadruplex:
Is it absolutely no preference, with whatever codec you do? There is no preference of course not - but, as has already been written: A data-reduced signal (a question is that DV) loss brings nothing to save.
Antwort von Gimbly:
There is no preference of course not - but, as has already been written: A data-reduced signal (a question is that DV) loss brings nothing to save. So I can keinerleih quality improvement through use of other codecs achieve (no improvement over the original, but compared to the standard MS codec)?
Antwort von Gimbly:
I think I've now understood: at the capture of DV cassettes is generally 1 to 1 on hard drive transfer. The codec has nothing to do. Right?
But what if you are want to work with filters (eg deinterlace). How do you then proceed? Or if, for example, directly into DivX would like to convert.

But what if you are want to work with filters (eg deinterlace). How do you then proceed? Then, the DV signal necessarily unpacked. What codec are you then save depends of your intentions and your software environment. Do you want the things back as a computerized archive and do not plan on finishing, the DV codec ideal. If the filtered / edited video is still in full-cut programs further or to be s.Ende a DVD coming out, it may make sense to lossless codecs such as HuffYUV use. Presupposes, however, that the following Programs synonymous HuffYUV accept. QuicktimePro under Winbugs zickt for example.
Or if, for example, directly into DivX would like to convert. Then you konvertierst to DivX - fettisch.
Antwort von cmbfilm:
Now closes the circle back to my original question, namely how to use VirtualDub for the desired codec choice.
If I, as a Device "USB Video Device (Direct Show)" or "DV-VCR (Direct Show)" (the latter if I connect via firewire) is one telle, I have to video / compression only "(No compression: dvsd)" for Choice.
Antwort von Quadruplex:
You have to start the video with the capture module as DV save, then open up with VirtualDub and select a destination codec. I do not know whether it is with the VirtualDub capture module would be possible in principle, synonymous direct dubbing to other formats like DivX to convert. Among quality aspects, it is not useful. Video data reduction works s.effizientesten when they are done in two passes. The time is now not in real time.
