buzzz from animation image
Hi there folks.
I’ve run into an problem with a couple of files that I’m currently working on. A while ago the company I work for put together a bunch of promotional animations for a client to be delivered via the web and on DVD.
Now they’ve come back wanting a copy of them all on DV-CAM. So I’ve imported all the full size animation codec files into FCP rendered them out onto a DV timeline and prepared myself to play them back to tape….. however on a small part of one of the sequences there is a very audible buzz coming from the TV monitor (it’s the picture causing it not the audio as this is turned off) any ideas as to what is causing it?
When the opacity drops the buzz/hum also drops and it’s only for about 2 seconds of a 1min piece. I’ve tried positioning the clip slightly differenctly in the frame and also appling a broadcast safe filter and a shift fields filter and a flicker filter none of which seem to make any difference. The buzz is on the original file so it’s not the rendering that has create it.
Also as a secondary thing just got a new Sony M-15 DV-CAM deck that is plugged into a FCP Duel G5 editing suite. I’ve previously been working off DigiBeta through an AJA I/o box…. I’m having trouble figuring out how to generate timecode onto the DV-CAM deck from Final Cut. Can you do this Via Firewire or is it only possible when running in SDI or Composite? Usually I’d just go into edit to tape and select black and code at which point I’d be asked to insert a start timecode set the deck’s regen/preset settings and away I’d go…. not any more. So how do I get the timelines timecode onto the tape so I can start my programmes at 10:00:00:00 do I need a new timecode generator to do this??
sorry that it’s a long one… feeling chattly at the mo

Check out your View>Range Check and see if any of the colors are out of safe for Saturation.

The buzz is from your monitor? Could be an issue with the monitor – how are you feeding it? I’ve seen analogue signals cause audible buzz on badly setup/older monitors. Is it accompanied by visual interference? If you really want to isolate this problem you’ll have to a) put the Mac output through a scope to check the levels and b) try another monitor. Sorry if this all seems obvious, but I just wanted to avoid you spending a lot of time tweaking things on the mac.
As to the deck issue – I don’t use the M15, but in order to receive timecode info from the Mac to the deck you will need to use 422 control on the 9-pin you used with the Digi – firewire won’t do it to the best of my knowledge. Hope this helps and isn’t more stating the bleeding obvious…
