CTL Timecode?

Anyone has a workaround/plugin to zero a clip's timecode at a given point?

I am doing more and more production work and audio transcript files, usually mp3's for quick file sharing, do not retain the original TC stamp of the video they belong to _they just all start from 00.00

CTL isn't really the right term, it's just bad jargon carried over from the tape days. CT pulse would be more appropriate.

What I am really looking for is the possibility to not have to have a project for each interview to be able to match the transcription's TCs.


This is how I am doing it now and the floating TC window is helpful. I could make it out just from the timeline's time markers, but the floating window is a better experience: it has both TC stamp and gap info, and it's got big digits.


However this doesn't work on browser clips. I'd find it really useful if a similar behavior was possible in the browser as well, for example if the skimmer info callout had gap info just the same where I could see gap from in point and/or gap to out point, or simply if the floating window followed the skimmer, just like the viewer tab does

So you're basically looking for a way to visually "log" clips in the event browser with a "gap" timecode (or starting time) and perhaps the In and Out points (Source Timecodes) within the clip? Something like:


What you're looking at is an effect you can apply to clips in the storyline. You simply double click on the timecode clock in the inspector and type in a start time (it doesn't have to be exact... just a reference point):

[The Source Name Fit (X) is an X-scale slider to help squeeze in a long name in the space provided].


The "Source" is the clip name. You can change that by simply clicking the name in the Browser and typing a new one, or in the storyline, right-click on the clip and select Rename Clip from the popup menu. This effect automatically updates the Source and In/Out selection/trim points (In/Out). [Short descriptive names are very useful — if you rename a clip in a storyline, it does not change the name of the clip in the Event Browser — if you rename a clip in the Event Browser, name changes are only reflected in the storyline if the clips are added after the change...]


You can view the data in the Event Browser IF you save the clip as a Compound Clip. Don't worry about creating a bunch of CCs, they're more or less "weightless" (just kept as some XML descriptive text). You can "process" your imported clips by adding them to a storyline and creating the CCs — saving them to a different dedicated Project (for convenience). When you're finished using the log info, you can simply select your storyline, Break Apart Clip Items, and turn off all the Log Clip Effects in one move — Select Remove Attributes, click on the Effects checkbox to turn them all off then click on Log Clip to select only it, and remove.


If this looks like something you can use, let me know and I'll post it for you. If I completely missed the point... well... never mind. ;)

FCPX actually has two rather nice timecode plugins: one is an Effect that you apply directly to individual clips and one is a generator that you can place over the storyline. They both have a Timecode Offset parameter that you can set to make adjustments to the displayed time. Both have the option of using Source (the timecode of the individual clips [or the generator]) or Project (the running timecode of the current project the clips are placed in) plus you can choose which timebase you want to apply.


With the generator, which is placed over the storyline, you can set a "zero point" anywhere you place the first frame of the generator in your project (Timecode Base = Source). Getting negative offsets is the trick. That essentially means setting the Timecode Offset at a modulus of 24 hours. For instance, a Timecode offset of -1 minute would be 23.59.00.00 (technically, 22.59.00.00 because the Generator version accurately displays the "zero time" as 01:00:00:00).


My advice: don't try to set the Timecode Base to a specific time base— just stay with Project or Source.

Thanks, it's an interesting tool. Basically the SOT clips become CC SOT clips and then I start the logging process. I'd be quite happy to give it a go!


I do most of the work on "paper" (it's actually a word document), following the transcript, checking the original clip for expressions, writing in and out of soundbites, paraphrasing info, etc.


Going through a project timeline, I can't quickly mark things on the original clip - or I have to repeatedly match frame.

Just to give you an idea of the drudgery: I am working on about 10 interviews, 30-40min long - everyone has to appear in at least one of two 3min videos for a technical audience. It would really speed up my work if I could just go from paper to browser and TC's matched, mark favourite or reject, add keywords, markers, notes and do all the beautiful logging things you can do in the browser.


One other solution would be to avoid losing original TC info from the very start, but I haven't been immediately successful. I am sure there's a way of retaining original TC on export, maybe not inside FCPX, but there will be something out there to do the job. I would have to export an audio only .mov or .mp4.


Sending out for transcription/translation the entire clip file is not an option for my environment's connectivity. I could use a proxy video retaining the same timecode, but I have to find a way to do it and it is still a lot of recompression time on my part. Plusa lot of the times I am asked for youtube links, since typers are seldom tech people and more often than not I get distress calls. It's just so quick to pull out an .mp3 straight out of FCPX.
