60FPS video file to a 30FPS intelaced video, possble?

[lostless]

I have a video that i shot with digital camera and is 60fps i want to convert it to edit and then burn to dvd, but when i do, i lose the smooth playback cuase when converting to DV, it drops half the frames. I have mac osx, and was wondering if any app out there can interlace 60fps of video down to 30fps interlaced.
The way im doing now to plug my ibook into my set top dvd recorder and let the ibook interlace in real time with its s-vdeo out. But i wanted to avoid going through an analog medium, the to a compressed video back into DV for editing.
Thank you

If you are using the Mac OS and Mac software only, you would be better off asking this in the Mac Forum. I can move it if you like. And please fill out your computer information to make this type of question easier to answer in the future, or you will likely get mostly PC solutions.

And welcome to our forums.

I can use a pc if needed, but perfer not too since an old crappy laptop thats slow. Ill be happy to have this moved to teh mac forums as well. If anyone here knows an answer to my ?, feel free to let me know, mac or pc.

Explain better how you recorded this video. What camera? What format tape?

Normal DV camcorders record 60 fields per second (interlaced) each field offset in time by 1/59.94sec. This is also known as 480i/29.97 frames per second. This is directly compatible with DVD and will play smoothly. If you deinterlace this video to 29.97 progressive frames per second, it will appear studdered in action sequences. You can still put this on DVD by splitting back into fields but the motion resolution will remain 1/29.97sec and still be studdered on playback.

High end progressive digital camcorders are capable of shooting 720p or 480p at 59.94 progressive frames per second. This is what ABC, FOX and ESPN use for 720p or 480p ATSC sports coverage. Motion resolution is 1/59.94. This is not compatible with DVD unless converted to 480i.

NTSC DVD only supports 480i/29.97 and 480p/23.976. Normally 480i has field motion resolution of 1/59.94sec. The DVD player frame repeats 480p frames 3-2-3-2-3-2 to play at 59.94 frames per second. This is done to minimize flicker. Motion resolution is still 1/23.976sec.

its an avi file, 320x240, uisng motion jpeg compression at 59.94FPS . I was just curious if thre was any way to make an interlaced video out of the 60FFS (59.94 to be exact) to 30 (29.97) inerlaced frames with each field contining 2 frames of the original source in software. Im well aware how video works and all the differant formats, and what interlaceing and deinterlacing, 3:2 plulldown ect. I know at 320x240 there isnt much to work with. Just looking for a software solution. as i siad, i could always use the ibook s-video (which interlaces all video coming from the ibook) into my dvd recorder and works pretty well.
Thank you

Easy to do in Premiere, FCP, Vegas and probably in iMovie or Virtualdub.

Set project timeline to 320x240 progressive 59.94 fps and export (MPeg2 encode) as 720x480 or 352x480 interlace 29.97 fps. The software will create an even field from frame one and an odd field from frame two and so on. The MPeg2 encoder does the interpolation.

Or set project timeline to 720x480 or 352x480 and import the 320x240 progressive. In this case the editing software does the interpolation.

Found a mac program that does it!!!! JES deinterlacer. Works great. I just used standard conversion to ntsc and it interlaced teh video very well. Im impressed. So for all mac users, jes interlacer is a very nice and free reinterlacing program.
