y262 can encode interlaced content just fine.

Well maybe I am the wrong one to answer that. As far as I know a field picture in the context of Mpeg-2 is a coded picture where picture_structure is equal to "Top field" or "Bottom field".

Anyway, have you tried true interlaced (with combing artifacts when you weave/overlay) with y262? How well does it perform, say at 4mbps for 720x576 during motion scenes? Last edited by kurkosdr; 4th February 2025 at 17:33. |

I would not call that 'true interlaced'. I would call that treating interlaced video as progressive. It is never good. If a codec cannot encode as fields it is better to bob deinterlace than encode the two fields from different timepoints in the same frame.

What kurkosdr described, with is own words, appears to be interlaced content. I do not know why you suddenly come along with treating it as progressive content. No one talked about that. Can you explain further?

I mean encoding an interlaced frame as a single picture with combing artifacts (treating it as a single progressive frame) results in much worse quality than encoding the two fields as seperate pictures and weaving during decode.
The combing artifacts are very sharp high frequency detail that does not work well with our lossy frequency domain compression methods. This is even worse when considering 4:2:0 chroma sampling.
