@Fredo no worries, it might be hard to follow how I explained it.
Take this scenario: DX tracks in a 2hr docu
We’re past picture lock. They want to switch out the narration, and it’s new words, so there’s no wave form matching. They give me the clip from the new VO recording and say the the replacement clip starts at Audio SRC TC 1:02:01:13. So I bring the clip into the track below. I can see the origin being 0:59:58:595 and offset 0. Now I need to trim the head so the event starts at origin 01:02:01:13. And I also know that in the NLE the clip started at 1:24:43:21 on the timeline (both data points may have come from a re-conform EDL or similar information).
Absent information that gives me the SRC TC of the event start, I can see that I need to trim 2:02:23 from the front - after using two calculators outside Nuendo (.595 is 14 frames @ 23.976). So I drag the front until offset reads 2:02.959, and then align that with snapping to the grid at timeline TC 1:24:43:21.
And I agree that frame boundary is not precise enough for the final edit. But I want to be frame aligned when I bring the clip in so I keep sync. Once I know it’s lined up properly the same way it was in the NLE, then I can refine the event start subframe to improve on that.
If Nuendo were to display the converted SRC TRC in the event description or in the status line, then I could simply trim, until that number matches what editorial gave me.
The math for what is displayed should be simple: Take the Origin TC, add the offset, and round to the nearest frame rate boundary (either based on audio meta data or project frame rate, or last resort override).
Also worth noting that the meta data of BWAV does contain the frame rate in the description field, so the display conversion could use that to round to the nearest frame:
Description : sSPEED=023.976-ND / sTAKE=01 / sUBITS=$00000000 / sSWVER=8.04.1993 / sSCENE=1 / sFILENAME=1T01_01.wav / sTAPE=AKGEN / sCIRCLED=FALSE / sNOTE= /
To clarify, I don’t need Nuendo to automate that trim based on information. But I’d like it to help me avoid having to math every time (by head or calculator). As long as it can display the effective Source Start TC of the event based on current trim, then I have enough information to efficiently trim the clip by hand (yes, if it’s an hour-long clip that may be a bit unwieldy, but still just a few clicks/drags).
