LHi has the same upconvert engine, so it will work.

Much easier on your footage to add frames than to get rid of them. I would argue that converting your HD 23.98 footage to SD 29.97 first would allow you to preserve each bit of footage’s natural look. Since you are delivering 29.97 and some of your footage is 29.97, you should get everything to 29.97 before you edit. This is my opinion, and some people will tell you otherwise and have good reasons for it too, but this is what I would do in your scenario.

You can use a file based transcode or a hardware downconvert to get your HD 23.98 footage to SD 29.97. Transcoding is easy with Compressor – you create a preset that will output to the desired frame size (720×486), codec, and frame rate (29.97), with frame controls set to fast retiming, best resizing, and lower field first output. Hardware downconvert is also easy with the Kona – you make a sequence that is HD 23.98 and drop your footage onto it, then set the secondary output of Kona to SD NTSC (so that the Kona hardware does the pulldown insertion and downconvert). Then you can do an edit to tape of your footage out to a DigiBeta and capture it back in as SD from tape. That’s if you have a deck handy…

If you want to edit everything at 23.98, you can, just be aware that when you upconvert SD 29.97 to HD 23.98, you lose frames and perceived resolution. Your original SD footage is also not going to look so nice by the time you later downconvert your whole sequence.
