I'm wondering what exactly it is.I know it syncs stuff together, but isn't it a 1/4 jack?How does it work :confused:
 
Society of Motion Picture and Television Engineers (SMPTE) time code does indeed come in the form of a 1/4" cable, but you need a SMPTE reader/writer on each end for it to do any kind of syncing. It is usually used to sync audio to video, but has been used for many other syncronization applications as well.
 
it means something like.......

society of motion picture technical experts, except it is (i think) in french (you did not ask, and I'm not going to say).

simpte usually means simpte time code. this is a unique time code generated sequentially for every frame of video and written on the tape with that frame.

usually it starts with the first frame of a segment of video, but some systems let you number it from the start of a group of sequences, so they fit together and do not have duplicate time code numbers. in other words if you record 2 one minute segments on the same tape, the simpte time code will have duplicate numbers in the two segments. of course on tape, you know which one is first, but if you transfer it to disk with hundreds of others, eeeiuuwww.

most consumer dv format cameras don't bother with simpte, some prosumers do, almost all pro (all I know of) let you gen simpte code.

simpte lets you absolutly identify one frame from possibly many others that may look very similar.

its very old tech, but still useful.

I know i'm spelling it simpte, but that the way most people say it (sim-tee).
You can also sync a specific clip of audio to a specific clip of video with simpte.
