In some tasks for TV broadcast in interlace formats 576i and 1080i a have some problem with vMix:
1) there is no settings for Aspect radio (1:1, 4:3 and 16:9) in format 720*576i stream to internal RTMP-server of broadcast company.
2) there is no settings for Interlace encoding in format 576i and 1080i for stream to internal RTMP-server of broadcast company.
3) Playing files with interlace with lower field first (AVI DV PAL format and MP4 PAL format) ooccurs with trembling picture output and there is no way to change fields order.

Please consider adding these options in future releases of vMix.
Thanks.

If your vMix project is 576i, it will stream interlaced signals
OR
You can use FMLE along with vMix (if I remember correctly, not used it for a very long time), it does what you need
OR
Just use EXT out to feed another encoder with appropriate settings/parameters. I would use FFMPEG or VLC or an hardware encoder.

I just make a project 576i, external settings is 576i, then add output stream to the input - in the pucture I see what it is interlaced, but there is no interlace flag in the stream, and vMix shows what it is 25p stream.
