Gamut Error Fcp

NEXT >> • Gamut error rejection by nitin kulkarni on Apr 14, 2009 at 2:39:46 pm Hi, I got tape rejected for “RGB composite gamut” error. I have gone trough some forums and done some research but still some things are unclear for me. After got rejected I arranged for one scope with gamut indicator. 1. I have already applied broadcast safe trough out my program to 95%, even to text, flashes etc. 2. It’s not showing peaking anywhere above 100IRE. 3. I got lots of flashes effect (dither dissolve) and fire footage in my program where I am getting this gamut error. It’s all showing fine in waveform and I can not lower it any further as it will look bad creatively Dose this gamut error means there is some part exceeding 100IRE even after applying broadcast safe, but it not visible in normal FCP waveform? How can I make entire frame dull for this gamut? Or is there is there any another way, or I am missing something.

This required investing in some very expensive test equipment and logging software.Recently we finished editing a 1hr doco and mastered it to HDCAM. This involved a full colorgrade using Apple's 'Color' and Final Cut Pro. We had 'broadcast safe' turned on in 'Color' and everything worked just fine.After mastering we put it thru our QC and some Gamut errors were detected. https://forums.creativecow.net/thread/8/1031594 On closer inspection, using scopes we could not see any errors at the reported spots. But on sending the signal directly into the QC room all the alarms started ringing so we had a problem! As a matter of interest we set our Gamut detection to the BBC spec which is 3% but the default is 5%.Interestingly enough, while monitoring the QC readout I applied the FCP 'broadcast https://discussions.apple.com/thread/2750427?tstart=0 safe' and I still had Gamut errors. Then I applied a filter and reduced the 'saturation' by about 5% and voila!; Gamut errors gone!So the moral of the story is; don't always trust 'Broadcast safe'; in either 'Color' OR 'FCP'.But if it makes you feel any better we reject about 80% of outsourced masters, due to many errors, mainly audio. Be warned its a minefield out there and while more and more productions are edited and mastered on the kitchen table more and more masters are going to be rejected.Baz MacPro Octo, Mac OS X (10.6.2) Posted on Feb 10, 2011 4:57 PM I have this question too Close Q: When 'Broadcast safe' is NOT broadcast safe All replies Helpful answers by Studio X, Studio X Feb 10, 2011 5:27 PM in response to bazinoz Level 7 (27,074 points) Feb 10, 2011 5:27 PM in response to bazinoz Just so I'm clear - you have external scopes yet you rely on FCPs or Color's' (known to be suspect) internal scopes while you are doing your range checks during grading?x Helpful (0) Reply options Link to this post by Shane Ross, Shane Ross Feb 10, 2011 6:34 PM in response to b

first saw the news of the Digimetrics Eos plugin for Final Cut Pro we thought 'nothing new' as it has been done before. Today a video for the Eos audio 'legaliser' was brought to our http://www.fcp.co/final-cut-pro/news/398-fixing-video-and-audio-levels-to-broadcast-standards-in-final-cut-pro-using-digimetrics-eos-plugins attention, so we thought we'd take a quick look at both. Broadcasters will find any http://www.tek.com/support/faqs/why-do-some-test-signals-show-gamut-error-directly-generator-and-look-really-bad-when-c reason to reject a tape or file these days file for transmission. Gamut errors have been a particularly annoying reason for failures over the past few years. Sometimes watching the 'scopes isn't good enough, the internal ones in FCP aren't great and shouldn't be relied on for final mastering. So what can you do to make sure your project that gamut error you've spent weeks on gets the thumbs up from your broadcaster? You could run it through an external 'legaliser'or you could look to software to do the job for you. Digimetrics have brought out two plugins for Final Cut Pro that will make sure that your video and audio levels are within specific broadcast standards. First of all it is a bit confusing to call them 'Eos' - they have nothing to do with gamut error fcp Canon's DSLRS! Secondly pricing is a little high for the FCP ecosystem at $299 for each plugin. Toolfarm has had promotions running on both these plugins so we would check there first. Digimetrics has demo videos of both the video and the audio legalisers. We should also point out that broadcasters can reject a programme if it fails a Harding test. Kanye West's video 'All of the lights' has been flagged as particularly bad. (Since removed)The Eos plugin will not fix flashing pattern problems. Eos Broadcast Video Plugin for Final Cut Pro In regards toColor Gamut, Eos offers the ability to set limits for measurement and correction (and, by default, correct gamut usingAutoFix) relative to EBU R103 in several methods: Percentage of legal limits Millivolts (mV) IRE (absolute value adjusted to 0-255) You can choose to measure gamut against ITU color standards BT.601 or BT.709, or define your own custom color space using the Y', Cb' and Cr' coefficients for the RGB components. Measurement and correction results are provided in an XML-based report, showing which frames are out of gamut, and if AutoFix is enabled, which color components were adjusted. Safe Title/Action Area overlays are provided in the preview window for: NTSC 4:3 and 16:9 (525 line raster) PAL 4:3 and 16:9 (625 line raster) where applicable, overlays for 14
