[FFmpeg-user] Question about progressive to interlaced

[Renvoi]

Dear ffmpeg-user at ffmpeg.org

I want to  progressive to interlaced conversion
is there any way?

Code I tried on how to convert a progressive sequentially
numbered PNG file to interlaced.

①-top 1 -flags:v +ilme+ildct-top 0 -flags:v +ilme+ildct
②-vf tinterlace=interleave_top
③telecine=pattern=23

but it doesn't work
