Hello Timo,
Thanks again for the response. I will attempt to help where possible.
Timestamp repro -
Set up identical Nuendo Live and Nuendo 5 systems fed from the same source, we use Madi.
Set up to chase LTC.
Do a test recording on both chasing code.
Import N5 and NL files into any workstation spotted to timestamps.
NLive files are offset significantly, a few frames.
Change buffer settings, record again.
NLive files are still offset but by a different amount.
Change MTC sync devices if you are able.
NLive files are still offset but by a different amount than the N5 files.
Change preRecord amount.
NLive files are still offset but by a different amount than the N5 files.
- To eliminate variables we simultaneously tested with NLive, N5, PTHD, Cinedeck, EVS, SonyHR, KiPro, and MetaCorder. They all were as close as could be expected except NLive which was a few frames off.
Dropped samples repro -
This one is more difficult because it’s not consistent.
Set up identical Nuendo Live and Nuendo 5 systems fed from the same source, we use Madi.
Set up to chase LTC.
Do a long test recording on both chasing code, we used 3 hours.
Import N5 and NL files into any workstation spotted to timestamps.
Move NLive files so that an audio hit at the beginning lines up with N5 files.
Examine a hit near the end of the files, look to see if they’re exactly lined up.
You may need to do this a number of times, it took us 5 tries before we found one that dropped samples. On the other hand Tom had it happen on quite a few recordings, there does not appear to be a pattern. The only thing we can guarantee is that all systems have been set up correctly and clocked correctly; we used identical hardware for our NL/N5 tests and we’re very good at clocking and synchronization issues.

Sincerely,
