Sync Problem with VT

Postby Masato.Y » Sun Feb 22, 2009 08:53

HI,
I use a VCube and a PMX with VT(virtual transport). I Usually set "follow VT" on.
When I 'm editing on PMX sometimes VCube runs in vari-speed so not in sync with PMX.
I set "follow VT" off then VCube runs in normal speed but when I repeat rewind and fast forward on PMX VT stops different position from PMX.
Is it bug?

Thanks for your help.

Hello Masato.Y

Few questions:

1) Are you running pmx and vcube on a single or multiple computers?

2) If two computers what is each machine clocking from?

3) What sample-rate and frame-rate are you working at?

I have been unable to duplicate your problem, but our set-ups may be completely different.

Best,

Mark

Hello Mark

Thanks for your reply.
1) Are you running pmx and vcube on a single or multiple computers?
2) If two computers what is each machine clocking from?

My pmx and Vcube are running on each computer (2 computers).
Each machine is locking on video reference and PMX is set in clockmaster/timecode master and VCube is set in clockmaster/follow VT(not timecode master).

3) What sample-rate and frame-rate are you working at?

I'm working at 48khz / 29.97dfs .

Thanks for your help.

Hello Masato.Y

As I rarely ff/rw (since I use my keyboard mouse for locating/playing etc... as opposed to the transport panel on my controller) I don't really experience these issues. However:

This definitely happens - in this case the v-cube will not necessarily park where pyramix stops after play/ff/rew.

This I cannot seem to reproduce. You said you are working at 29.97 locked to video ref. Is the actual video you are working from 29.97? or is it something else 23.98, 24 etc...? Is it possible that you could send me a screenshot of both your pyramix and v-cube screens with the vt clients window open as well? And the information window open in addition for the video file on the vcube? mark@pin3hot.com
