It's to leave room before first picture, for slates, countdowns, test signals etc, while still preserving an easy count of running time for the video. Yes, it traces historically to broadcast and in particular videotape. Many tape-based editing systems couldn't deal with 24-hour wraparound, so the next even hour became traditional 'time zero'. I suspect ...

Some projects use the hours field as a reel/tape/memory card indicator. Many cameras permit setting the TC hours number arbitrarily to support this usage. You could set the hours number in Pro Tools or FCP to conform to such a system if required.

The Timecode effect (effects>text>timecode) will add a timecode, but it's measured in HH:MM:SS:FF rather than milliseconds. You could do it with an expression by adding a text layer, and applying an expression to the Source Text property. Below is an expression that returns what you want. To apply it, alt-click on the stop watch for the text layers Source ...

Various places I've worked have found different solutions. Some record the LTC from a broadcast video tape to an unused track. Some will reuse a track from an earlier project. The first is slow (1:1), and both are inflexible. Hardware TC generators are flexible, but it's still real-time creation. I offer a free 32-bit Windows utility that can generate an ...

More and more cameras are including GPS time sync now that they almost all use them for location information. I am sure you can find a camera at any price range that includes this capability. The GPS should keep your cameras within a few hundred milliseconds of each other. Take them for a run at Best Buy or a similar store, letting them run for a while to ...

This doesn't cover the applications, but it gives a succint view into the nuts and bolts: Phil Rees

I know this is a very old Q, but it should be pointed out that a 'negative timecode' makes no sense. The SMPTE frame before 00:00:00:00 is 23:59:59:29. The namespace for drop frame (and non-drop) codes is already well-defined -- no need to postulate negative values. If there are systems or programs that use this notation, they should be rethought.

Taking into account that frame dropping works on a 10min-regular basis project offsetting by a multiple of 10min should keep frame dropping at the same positions I guess the correct way of doing this is on a regular basis.

Are you sure that there is not a problem with the actual recorded timecode? Under certain situations (such as two clips with a blank spot between them on the tape) the timecode can get screwed up. My guess is that this is what is happening. It is weird that you would end up with a problem with the final output as a result of this though. I've normally ...

Go into your capture settings and first try non VTR controllable device and if that does not work, there is a check box I believe for warn if there is dropped frames uncheck that, there may be another for stop capture if there is dropped frames, uncheck this as well

FFmpeg can do this. Example from the FFmpeg Filtering Guide: ffmpeg -i in.mp4 -vf "drawtext=fontfile=/usr/share/fonts/truetype/DroidSans.ttf: timecode='09\:57\:00\:00': r=25: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: box=1: boxcolor=0x00000000@1" -an -y out.mp4

The reason you cant get the durations is because a marker is just reference to a point in time, not a time range. This time around you will need to find the durations manually either by opening the clip or subtracting the time of the previous marker form the current one. You can give markers durations, but not as effortlessly as just placing a single ...

Libav has the tool avconv, which allows you to do that with the video filter setpts=PTS-STARTPTS. I haven't tried this, but the following should do the trick for you: avconv -i in.vob -vf 'setpts=PTS-STARTPTS' -c:a copy -c:v copy out.vob For more information you can check out http://manpages.ubuntu.com/manpages/precise/man1/avconv.1.html

If you have Compressor installed (comes with the Final Cut 7 Studio) you can burn-in a timecode to a video. You need to setup a preset at the beginning, but then you can make a droplet for further use.

Virtualdub will allow you to do this with the Add Frame Numbers filter (not just frame numbers, as implied by the name).
