I have written a Vegas 14 project that will do this.

You cannot stream interlaced video by any normal means. Hardware only afaik.

It is for 1080p 29.970 source, rendering to 1080i, Top field first. You would have to modify for other uses. AlI assets are included for a working demo, including a sample output file. Can do it this week, time permitting. You may PM me your email address.
It's only a proof-of-concept, so I can provide only minimal support.

ffmpeg can do this with the tinterlace filter, i.e. (this will double your frame rate):

Code: Select all

ffmpeg -i input.mov -vf tinterlace=interlacex2 -x264opts interlaced=1 output.mp4
