16:9 pal dv encoding problem

[Daniel Low]

Why are you resizing and deinterlacing?

As Daniel said, why deinterlace? More than likely, there is no interfield motion in your frames (i don’t know what camera you shot with), which makes deinterlacing a moot point.

Anyway, to directly answer your specific question:
The field order is getting swapped.

Here is an updated summary of what you should do.

Encoder
MPEG2
Video format pal
Frame rate 25
16:9
Bottom first (CHANGE TO TOP FIELD FIRST)
2 pass vbr 5.5 7.2 (CHANGE AVERAGE TO 6.4 Mbps, MAXIMUM TO 7.5 Mbps)

Frame controls (ALL FRAME CONTROLS OFF)
Resize filter better (liner)
Output fields same as source
deinterlace fast liner averaging

Adaptive details checked

Let us know if this helps.

[Michael Magallon] “Bottom first (CHANGE TO TOP FIELD FIRST)”

Ignore this. PAL DV is Lower (Bottom) field first

Turn of deinterlacing

MPEG2 PAL field dominance is TFF.

He is creating an MPEG2 file, not a PAL DV file.

“The problem is I have a clip with a small wind turbine which is spinning very fast. Aster encoding and authoring a DVD using DVD studio pro 4 this one clip looks bad, very bad. What am I doing wrong ”

However, the above comment is a little vague, so I will wait on responding further until he gives us more details. Does it look bad on a CRT, LCD, plasma or your computer monitor? Is the motion jittery on pans or is the overall quality not acceptable to your standards?

But please show a little courtesy Daniel Low, as I do to everyone on this board.

Thanks!

[Michael Magallon] “MPEG2 PAL field dominance is TFF.”

With all due respect, you are wrong, for DVD it’s LFF.

There are of course MPEG-2 based PAL broadcast formats that are TFF and I assume that is why you are confused.

If you or the OP are uncertain it’s best to set this to ‘Automatic’ in compressor.

Sorry for the lack of details.
I have filmed a 6 min video its been shot on a sony z1e the camera was set to down convert and I captured the footage as 16:9 dv pal.

The footage has been edited using fcp on a Mac book pro. I exported a self contained QuickTime movie.

I used the settings I posted and on my Mac book pro it looked ok, on lcd monitors it looks ok but this one clip looks really bad on normal TVs (crt).

I am now just about to try all the suggestions in this post.
I will post later with the results.

Thanks again for all info.

Just trying out what you suggested.
How do I turn off the deinterlace if I have frame controls off?)
