Re: Scan lines during pans - 12 years ago
If i'm not mistaken, output from your graphics card is RGB (or R'G'B'), which is not the same as Y'CbCr, which is what the MXO2 may be expecting. You may drive a different device control setting, etc. It's hard to diagnose without having the same gear. I'm sure others will have much better input (pun not intended)... -Daveby D-Mac - Café LA
Re: Quick magical DVD burn - Andy Mees, where are you? - 12 years ago
Harry, Apple already did this... Set In and Out points in a sequence, then choose "File -> Share". Pick the DVD option and it will create a disc image for you that you can burn to a DVD or play on your computer... Of course, there aren't many options, but it works...

Re: Scan lines during pans - 12 years ago
Chris, Is there a reason you have chosen not to use a screen capture utility? It seems a bit convoluted and needlessly complicated doing what you've described. (Of course, I could be missing something subtle here.) For Windows, I can only recommend Camtasia as a screen recording utility. There may be some others that work as well as Camtasia, or better.

Re: Logging Software for Canon 5D - 12 years ago
QuoteAndreas Kiel A .dmg uses the Mac file system while an .iso as a raw copy keeps the original file system. Easiest would be to create an hybrid file system (HFS+/ISO/UDF). This way any machine/OS will find a mount point. You can do that with Disk Utility. In the Image Format popup just select "hybrid image (HFS+/ISO/UDF)" On OS X 10.6.6, my Disk Utility doesn't offer the "hyby D-Mac - Café LA
Re: 16:9 DVCProHD 720p (23.98) and 4:3 DV (29.97, same disc, same menu, different tracks - 12 years ago
QuoteLoren Miller The questions... Should I encode the 720p asset to 29.97 anamorphic 16:9? Or leave it 23.98? Should I encode the resulting pillarbox 4:3 to 29.97 anamorphic 16:9?

Re: QuickTime playback framerate artifacts - 12 years ago
dcouzin, Thanks for the nice post. Apparently, your monitor's refresh rate can vary by ±2 Hz (I am not sure what that means, exactly). The response rate of 6 ms implies a complete cycle of rising and falling, which is less than the 16.7 ms of a 60 fps frame rate. This discussion is starting to go beyond my level of knowledge. Though, I would have to agree with Gerard (strypes) andby D-Mac - Café LA
Re: Thin green edge around frame of MPEG2 output - 12 years ago
QuoteGreg It's like the Quicktime app/viewer doesn't actually show all pixels in my HD excerpt QT or something. QuickTime has a weird (non-obvious) way of presenting frames during playback. For analog video, it may make sense to slightly crop some of the "noise" at the edge of the frame (and analog TVs usually cropped the "overscan" area).

Re: Thin green edge around frame of MPEG2 output - 12 years ago
Greg, So, when exactly do the green fringes show up? If you could export a few seconds of your original sequence and post it on Dropbox or one of the free file sharing services, it would help (I'd do some quick testing). This would be your HD ProRes export from FCP. Then, copy your settings summary from Compressor for the step that results in the green fringing (or maybe save your batch,by D-Mac - Compressor - Media Compression and Conversion

QuoteGreg And yes that makes sense to me too to not nest and just copy/paste. Just making sure. So drop the 'color smoothing 4:1:1' filter across the board into all clips in FCP? Is that what you meant? Or is there a third party plugin filter you mean? Nesting is fine if used properly. In this case, it's probably better to copy and paste everything from one sequence into another. I'veby D-Mac - Compressor - Media Compression and Conversion
Re: Question about NTSC DVD footage / PAL conversion - 12 years ago
I just opened a couple of VOB files from theatrical film DVDs and they also say "upper field first" in MPEG Streamclip, but in VideoSpec or MediaInfo Mac they are shown as progressive (and they are, in fact, progressive). So, I believe this is an MPEG Streamclip notational quirk. I don't know how this may affect the output from MPEG Streamclip.

Re: Thin green edge around frame of MPEG2 output - 12 years ago
Greg, Re-read the end of my previous post (I just added a couple of bits of info). Yes, by using one of the default presets, we can try to determine why the fringing is occurring. This is separate from the quality optimization aspect of the workflow. I am not a fan of nesting sequences, except under certain conditions.

Re: Thin green edge around frame of MPEG2 output - 12 years ago
Why are you changing the GOP length and style from the default values? Only under very specific circumstances should you do that (and if you know a lot about compression). Take a few seconds of your QT output from FCP (you can trim it in QT Player 7, if you want). Take that trimmed clip into Compressor and just select one of the best quality VBR DVD presets. Don't make any changes to the settiby D-Mac - Compressor - Media Compression and Conversion

For 60 fps, the corresponding interval (1/60) is ~16.666 ms. Your monitor has a gray to gray response time of 6 ms.

Fred, Thanks for taking the time to report back on the issue. The ProKit update you installed on 25 Oct. was 6.0.1. Interesting. You then installed OS X 10.6.6 (which contains ProKit 6.0.2) and used FCP a few days later. So, it seems that you were able to use FCS with ProKit 6.0.1 and ProKit 6.0.2 until yesterday... hmm...

The computer system is an old Mac Pro with four 2.6 GHz cores, 7 GB RAM, OS 10.5.8, no extraneous processes. Should this be suspected? FCP does not report RT failure.

Re: QuickTime playback framerate artifacts - 12 years ago
Perhaps, I wasn't clear enough. QuickTime Player is not intended to be a frame accurate playback application. It dynamically tries to adjust quality, in order to provide the best user experience over a vast spectrum of systems. For frame accurate playback, you need to use FCP (and maybe a few other apps). But, with FCP, if your system isn't powerful enough, you may need to adjust the RT setby D-Mac - Café LA
