Camera conversion? 24p?

Question

how do you convert your camera's frame rate to 24p?
i dont noe if its possible..iown a Sony DCR-HC38 Minidv camcorder...I would like to know how to convert the frame rate to 24p please

Answer 1

you can make the coversion, but you might not be happy with the results. if the subject is moving, or the camera is moving, there will be bad artifacts.

the first comes from de-interlace. your 30i frame is actually made up of two fields, both fields capture the entire picture at slightly different time. this off-set causes the moving objects to be in slightly different position in field 1 and field 2 so when combined to make a frame, there is blur.

the second comes from the reverse telecine operation. in order to make 24 frames out of 30, you have to throw out 6 frames each second which is done by removing every 4th frame. This results in a stutter step jerkiness in what should be smooth motion.

a program that speciallizes in the frame rate conversion will do a slightly better job as it will combine de-interlace with reverse telecine to interpolate a smoother finished frame sequence.

pro sound is sampled at 48K which allows the audio samples do be divided smoothly over various frame rates and generally that can be converted without a lot of artifacts. potentially a loss of sync can eventually occur if not corrected by the software, but that is no more difficult than what it does when adding a 44.1 k sampled CD to the soundtrack.

Answer 2

If your camera don't have the 24p function you can't convert the frame rate, on the other side if you convert the video to 24 fps in a NLE you don't will have the same quality and the audio track could loose synchronization with the video track.
My English is terrible but i hope you understand my point of view.

Answer 3

Use an NLE system, such as Avid or Final Cut Pro, to process the 29.97 NTSC video as 24p by using the “reverse” or “inverse” telecine process.

Answer 4

You can't convert the camera itself. As the other person who answered before me states, you must use an aftermarket program likle the ones suggested.
