It might be scaling artifacts... the higher-quality filters can introduce overshoot + undershoot ringing. Maybe this is the cause The Teranex device might give you control over the filtering... extrem

Make sure you export via **Scripting**, not file-- save as. FCP may or may not need to re-capture from tape. Not sure about that. If you need to re-capture from tape, there are some issues to watch ou

There are essentially three modes in Vegas: 8-bit (always 2.222 compositing gamma) 32-bit 2.222 32-bit 1.000 (this is the slowest AFAIK) The underlying difference is: 8-bit mode versus 32-bit mode 2.2

Re: Problem with my deck

On some DVCPRO VTRs I've used, they do a terrible job of playing back mini-DV (and fine with DVCPRO). There are dropouts even if the deck has time to get the tape speed right. Maybe something similar

Hey David, Thanks for the reply- I think the monitor may be able to apply the appropriate conversion. Didnt think of that. Hopefully I can make it to the next FCPUGTO meeting and bump into you there.

If you have the money, a Teranex conversion box will do a very good job. Resolution-wise, it noticeably gives a little extra resolution and no motion artifacts. The Teranex website has information on

In FCP, you can switch the waveform monitor between its two different modes. There is a setting for either "luminance" or "saturation". Luminance should correspond to Y mode, or "low pass" or "lpass"
