CCE SP 2.70 field order-My conclusion.

[SerbianBoss]

Best regard to all.

I want to share my conclusion about CCE 2.70 SP and with DV avi input(bottom field).

So, i capture with ADVC 110 in DV avi format which is Bottom field order.

Than i make this script:

LoadPlugin("Convolution3d.dll")
avisource("D:\CAPTURE\capture.avi")
ConvertToYuY2(interlaced=true)
SeparateFields()
odd=SelectOdd.Convolution3D (1, 32, 128, 16, 64, 10, 0)
evn=SelectEven.Convolution3D (1, 32, 128, 16, 64, 10, 0)
Interleave(evn,odd)
Weave()

Than this script load in CCE 2.70 SP

Because DV avi which i used is Bottom field in CCE in Advanced Tab i set:
UnChecked option Output top field first stream and Offset line i set to 0.

I do this because the quote from CCE SP 2.70 documention, page 49
First said:

Specify the field order of output stream. If it is selected, an output
stream is top field first. If not, an output is bottom field first. This
setting works on MPEG-2 output.

If it is true you must Unchecked Output top field first stream(if your source is bottom field first)

Second I use Offset line 0 because this (CCE SP 2.70 documention, page 49)

To set field order correctly, you have
to care about Offset line setting.
• If the field order is same between the source and the output,
Offset line should be 0 or even number.
• If the field order is different between the source and the output,
Offset line should be 1 or odd number.

So, my source (DV avi) is Bottom field and I want to make Bottom field output so I use Offset line 0 because my input source is the same like output. So you must select 0

With that way, my DVD is not jerky on computer or TV.

I think that this is correct for for DV avi sources. If my conclusion isnt correct then you said what is correct.

Best regard.
P.S I must say when I using the offset line as 1 my output was jerky.
Second i am from Europe so i use PAL picture

I'm going to guess that your capture card is really capturing TFF and not BFF that you believe.

CCE only encodes TFF, no matter what settings you use. It's silly, but true. The Offset line setting of 1 will clip one scan line effectively converting TFF to BFF or BFF to TFF.

All Mini dv-cams output BFF, but many capture cards output TFF. Since your videos playback jerky with Offset Line set to 1, I'd guess your source is actually TFF, in witch case Offset Line set to 0 would be best.

I am 100% sure that Canopus ADVC 110 capture bottom field.

Because when i import my DV avi in Sony Vegas and when i click right click on my DV avi i chose properties. And it write Low field first(which is bottom field first)


So In CCE i unchecked Unchecked Output top field first stream and Offset line must be set to 0.

This is my conclusion and i think that this is correct.

One more thing. When i finish encode in CCE, that MPEG file i opet again in Vegas just to see field order. And in Vegas again write Low field order (bottom field).

If it is true CCE is output Bottom field order when you unchecked Output top field first stream and offset line set to 0

Sorry, I don't use Vegas. Is that the actual properties of the video clip, or is it the project settings? It looks like the field order can be changed.

Open the Mpeg file in Bitrate Viewer to see the encoded field order. You can even use Restream to see field order.

As far as i've always known, DV is bottom field, regardless of capture device..
Whether it's your Canopus, or my ADS Pyro A/V Link...

If it is true CCE is output Bottom field order when you unchecked Output top field first stream and offset line set to 0

Yes, same with me...
The eventual test is on a television screen..

If you get jerky motion on panning action, than that's a dead giveaway..
You would therefore have to check that option..

So enjoy, be happy, and don't strain your brain any further...

Ciao!!!

This is the actual properties of video clip, not project settings.

Vegas correct show field.
I downloaded ReStream and its show the same field like vegas.


When i import movies which i encoded in CCE SP with settings -Unchecked Output top field first stream and Offset line 0, ReStream show this picture:



As you see mpeg2 is stay bottom field first.

Canopus is BFF, as mentioned above i think that is true of all DV devices.

It looks like they changed the Field Order options for CCE 2.70.........

The last version I've tried was 2.69 and that version would only output TFF.

I dont know for older versions, but version 2.70 100% produce bottom field first when you set these two parameters.

See, the manual for CCE SP 2.70, page 49

Specify the field order of output stream. If it is selected, an output
stream is top field first. If not, an output is bottom field first. This
setting works on MPEG-2 output.
It is important to set correct field order, because incorrect field
order causes stuttered motion. To set field order correctly, you have
to care about Offset line setting.
• If the field order is same between the source and the output,
Offset line should be 0 or even number.
• If the field order is different between the source and the output,
Offset line should be 1 or odd number.
