I'm having a problem with deinterlacing and I hope someone can help. I'm trying to convert to xvid avi or wmv (both show the same behavior). The issue is that on some animations or cartoons (Dr. Katz, Dilbert, thx intro from nemo) the picture breaks up along horizontal lines when there is any motion if I convert with deinterlacing off. When I turn deinterlacing on and convert, the line artifacts go away, but there are significant jagged edges. I've been using the THX sample from the beginning of Nemo as my test case since it is very short and displays the issue clearly. You can see the jaggies on the robot's shirt line and on the cow box. (I had used this to test the sound as well for the 5.1 wmv issue which Ting has fixed --thanks!)
The problem *seems* to be with the particular deinterlacing mode used. As a test, I played the Non-di converted video with VLC and used different DI modes to see what worked. Some worked perfectly while some produced the jaggies.
I searched the forums here and found a thread that I thought would help:
indicates that this:
"...deinterlace mode="1" method="0" to force deinterlace with method 0.
(blend, bob, weave/0,1,2 ?? )..."
can be used in a profile to select some "unsupported" DI modes.
and later in the same thread the author appears to have had success with this:
"...5. Insert a new line between the <video> line and the <size list="" /> line.
6. In the new line, insert the following text:
<deinterlace mode="1" method="1"/>..."
So I created a profile per the instructions and tried several different DI modes (1,2,3) but I keep getting the same result (including the exact same file size). So I'm wondering if this deinterlace mode feature has been removed (if so, can we bring it back?) or if the UI is not honoring that profile line any longer?
I should note that I've converted this clip with other software and it looks fine (no jaggies, no horizontal lines) so I really do think it's just a DI algorithm issue. Also, I've tried various (high) resolutions and bitrates and 1 and 2 pass with all basically the same results. Thanks in advance for any insights and sorry about the long-winded post.
