mpeg2enc Deinterlace error... it's not working

[jcpudd]

Every since updating to the most recent version of ffmpegX (version 0.0.9w) and the mpeg2enc.intel version deinterlacing causes me to get an error.

The inputs I have used is divx, H.264, and an MPEG4 mov. I have used all of these inputs before and it worked just fine.

This is the error I get from ffmpegX Process:

Thanks again

The framerate is detected as 23.976 fps (NTSC Film) which is never interlaced. So likewise you won't have to deinterlace this specific clip at all.

Well, I didn't know that 23.97 fps is not ever interlaced. Thanks...

Well, never say 'not ever'. You or anyone could write a spec and implementation for 23.976 fps interlaced content. It's just not practical, as interlacing was developed specificly for slow refresh rates on TVs with 29.97 fps (NTSC) and 25 fps (PAL) framerates.
If you can't see combing in scenes with movement (and de-interlace filters off), then you source video must be progressive and doesn't need de-interlacing.

I also understanded 29.95hz used colour NTSC and 29.97hz for black&white NTSC. I not found place where i get this info. But i am very sure is accurate info.
