Hello, I need to broadcast at the same time interlaced and progresive.

Interlaced in a local tv, and progresive at the same time in youtube.

I don't get this option, only get 2 of them interlaced, or 2 of them progresive.

My stream settings are:

The first is RMTP Server, with the addres of the local tv. In external output i have checked Vmix video /streaming and frame rate Pal50i 1920x1080. With this option I get a perfect interlaced video in the broadcast, but in youtube I get the same, so it appears the little annoying lines when there is some move.

If I check "use stream settings", the settings options are all progresive, so I get a perfect deinterlaced broadcast and progresive in youtube. In youtube is cool, quality is so good and better than in tv (we broadcast in SD) but I need to broadcast interlaced.

Is there a solution or I am doing something wrong?

Thanks in advance and sorry if my english is bad.
