DV decoder differences - update - Page 3

henryho_hk · 15th August 2006, 17:22

@WorBry, AviSynth does not know DV 4:2:0. It always takes it as MPEG2 4:2:0. Indeed, it does not know whether it is progressive or interlaced (which IMO is not equivalent to "field-based"). And I think AviSynth 2.56 will throw an error if you run ConvertToYV12(Interlaced=xxx) on an DV 4:2:0 source.

No it won't throw an error.
It simply doesn't know the difference between MPEG2 YV12 and DV YV12, because both are transferred to AVISynth using the YV12 FOURCC.

Actually, no it doesnt - I've just double-checked.

Cedocida set to 'forced YV12 (DV sampling)' output with

avisource("C:\DV Type II.avi")
ConvertToYV12(interlaced=true)

opens just fine in VdubMod. File Info gives 'DivX 6.2.5 YV12 Decoder' as the (stream) decompressor.

Edit: Sorry Scharfis, you got there before me.

Thanks for correcting me, scharfis_brain & WorBry.

This thread is confusing.

So did anyone come to any conclusions about what to use and what not to use?

swiego · 15th January 2007, 08:34

I'm wondering too.

I'm glad to have found this (I think), as I'd assumed that DV decoders wouldn't make a difference. Of course maybe that is the case after all... are the differences significant?

After studying this thread cedocida seems to be the best option.

To swiego:
The differences are significant. At least to a fairly experienced video encoder. For the casual observer they are probably only minor and in fact the added sharpness of some decoders only makes the stuff look better to them :P Chroma bugs can be noticeable on some material while on other they can be difficult to observe [under normal playback that is].

So, what decoder ships with Windows Vista? I installed Vista Ultimate and was able to play all my DV files out-of-the-box. I was wondering if this is one of the decoders described and tested in this thread, or something new. (I played the files with both windows home premium and windows ultimate.)

Just curious.

vlada · 14th February 2007, 18:07

I believe it is still the same:
5) MS DV codec (directshow codec) for W2K

I've been trying Cedocida, but I've had to disable it because vdub can't playback in real time with it. Anyone else had this problem?

Fizick · 5th March 2007, 21:55

yes, it is slow

wonkey_monkey · 6th March 2007, 01:23

Thanks Fizick... someone in another thread said it was fast, hence my confusion
