Default Reaper's strange approach to Timecode with Wildcards

Hi All,

I am trying to render multiple sections of video for a client using Reaper's rendering wildcard variable to append the timecode of the sections.

The problem is, the timecode of the wildcard is NOT the timecode I see on the timeline. For example:

My timecode at start of selection for render: 16:19:06:00
Reaper $Start wildcard timecode: 16-20-04.746

Same thing when I use the $minute $second variables.

Can someone enlighten me on this?

If you're looking for a wildcard that uses hours:minutes:seconds:frames format, there isn't one currently, unfortunately. The $start and $end wildcards will always be in hour-minute-second.thousandths format. The $hour, $minute, $second wildcards are for the time of day, not the timeline time.

But this is what I don't understand - if my timecode in Reaper is 09-59-00sec, why is the $Start wildcard giving me 09-59-35sec?

Check out the attached screencap...

I can't seem to reproduce this. Could you attach your .RPP or email it to support at cockos? We don't need any of the media, just the .RPP file.

Ah, sorry, it's because the project uses a 23.976 frame rate. At 23.976, frame 16:19:06:00 falls at time location 16:20:04.746.

What's needed, I suppose, is $timecodestart and $timecodeend wildcards.

Ok, so if I understand correctly, the discrepancy in the Clock (timecode) and the $Start variable is because they are not the same units? I'm struggling to see how this could be useful...

What is the unit used by the $Start wildcard then?

My advice would be to use 24fps or 30fps rather than 23.976/29.97, unless you have a reason to use 23.976... (Edit: ah, for a client, who probably requested 23.976? In any case, then, you should familiarize yourself with ND vs DF timecode, here's a link that might be helpful: http://www.bodenzord.com/archives/79)

As far as the use goes, it's a long story, buried in https://en.wikipedia.org/wiki/NTSC...

Thanks Justin - but I will be using the native resolutions and framerates requested by my client. Reaper should be able to adapt to that.

Which brings me back to my original questions:

1) of what use is the $START wildcard if the format does not match my project settings
2) what format *IS* the $START wildcard in?

Thanks in advance,
T

These were answered by schwa above:

v5.962 will have $starttimecode and $endtimecode wildcards in order to display the time in h-mm-ss-ff format. You can use a release candidate of that version (currently 5.962rc2) for testing via https://www.landoleet.org (you can visit the pre-release forum for more information on that).
