Recommended settings in my case? mts files from camcorder

[Perenista]

Guys, I have purchased a camcorder from JVC, the GZ-EX210, and it saves all recorded videos in the highest quality in mts. MediaInfo about the mts file (it is 1080i if I am not mistaken). Using MPC-HC you cannot notice it is interlaced, but when converting to AVI/etc. it shows.

Using Sony Vegas PRO 11.0 I was able to open the MTS. And I found this screen after editing, but have no idea what to insert there.

Can you recommend the settings which will give me the best possible quality? I want something as much close to lossless as possible. Don't care if the filesize would be huge or if it will take more time.

In the 1st image I selected NONE (progressive scan) as Field order, pixel A.R. 1,0000 and FPS 29,970 (NTSC) / Interleave every 0,250 seconds. Are these settings OK?

Do you have any advice on what options I should use?

My goal is to upload the videos edited by Vegas to Youtube, and keep the original file with the best possible quality. ;)

To keep the original file -> I would just keep it, not transcode it and probably throw away the original.
The source was interlaced, and probably TFF, so I would keep any intermediate interlaced and TFF.
For max quality I would rather bob to 59,94p using (Q)TGMC.

Youtube transcodes and butchers anyways, no matter what you throw at it.
For this occasion only you still may want to have a progressive version.
and for this you may give the job of deinterlacing back to Vegas as you did.

But this throws away temporal information that was still there in your interlaced source.
Keep your source still.
