De-Interlacing NTSC - Yes or No?

[Tchail]

I've finally gotten around to captuing my Star Wars THX laserdisc.

I have the Pinnacle PCTV USB 2.0 hardware, and have captured using Studio 9.

I did the capure using the S-Video input, and PMJPEG compression.

According to Video Vegas, the video has been captured with the bottom field first.

Now I want to crop to 720x360, then compress to 720x480 16:9

My question is:

In order to keep the highest quality possible, do I want to de-interlace the video?

Thanks in advance,

Umm, highest quality possible?

Issue 1:
Will the PCTV USB 2.0 capture 720x480 interlace?

Issue 2:
Does the PCTV USB 2.0 have a good comb filter for Y/C separation?

I ask because laserdisc is native composite. Most Y/C separators (S-Video out) in old laserdisc players were really bad.

Issue 3: Why MJPEG compression? Is that all you have? What bitrate will the hardware do?
I realize USB2 isn't up to uncompressed or DV capture which would be better.

Issue 4: Laserdisc is native analog, interlace, composite and letterbox. You will have highest quality keeping to native specs. This may vary depending on how you want to display the result. Keeping it native will work best with a high quality HDTV or high quality DVD recorder.

Issue 5: You shouldn't "deinterlace" telecined video (film original). You should inverse telecine to native 480p/23.976. This is something the HDTV will do for itself if you stay native. Studio 9 isn't going to have this option.
