Hi,

I've just read the FAQ, and there are several codecs available.

Does all have the same quality when uncompressing dv video ?

So which one is the best to use in avisynth

* DirectShowSource (works without any codec but slow when seek in video)
* ffdshow
* Canopus DV Codec
* Mainconcept DV Codec
* Panasonic DV Codec

Thanks

You can also add the Cedocida DV codec to your list. When is the last time someone did a comparison? Force of habit has stuck me with the Panasonic DV Codec, but I'm not married to it. Nevertheless, I find it to be quite reliable, and it seems to work well with a lot of video software. It will be interesting to see if others in this forum have made their own comparisons.

IIRC there's a comparison in the doom9 DV forum.

Panasonic DV codec is buggy and always converts to RGB. This loses the darkest and lightest shades within the DV data. The conversion is a waste of CPU cycles if you don't need/want it (when feeding CCE for example).

Cedocida is my favorite because it gives you a lot of control over the colorspace output and colorspace conversions.
