Ghosting Problem with Interlaced Frames
I posted this a while back – am still getting this problem. I’ve tried exporting to M2V through both Compressor 2 and using DVD Studio Pro’s own embedded M2V encoding. The output is the same.
The ghosting does not appear in Final Cut Pro (the interlacing is visible on computer monitor, you can see the lines and such) – but after being encoded to M2V – and output to DVD, this is the image you get if you pause the frame on TV in certain spots. It’s not really visible when in motion, only paused on moving frames.

We’re pulling it SDI through a KonaLH capture card at 10-bit, uncompressed. I’ve tried outputting it with various different bit-rate settings – and have tried many of the presets – the result is the same — changing the field order doesn’t seem to help either.

We have material that doesn’t exhibit this problem — and when watching it on the monitors we have, the interlacing isn’t visible. (so when watching movement, you don’t see the scanlines – even just framing through it, you won’t see the scanlines)
BUT, the material that DOES exhibit the problem shows visible interlacing on the monitor (you can see the scanlines during movement).

I’m a little confused on the particulars – but I would copy the MPEG-2 setting, and switch the field order. so instead of evens, or automatic, have it go on the odds.

I’ve tried even (bottom), odd (top), and none (progressive) — even (bottom) is what it’s supposed to take, but gives me the problem I have currently… odd results in a very shakey picture… and progressive makes the image flicker on the (B?) frames.
