Integrating Google AdSense and WordPress without a plugin

Published by Eric under Blogs, Web 2.0

WordPress logoI was using Martin Fitzpatrick’s excellent plugin called AdSense Manager to handle Google ads on my blog. Version 2.x worked well but version 3.x stopped working properly with sidebar widgets and the admin interface failed to commit certain page changes.

My quest to find a solution was unsuccessful so I trashed the plugin and looked for an alternative. Other WordPress plugins looked weak in comparison so I went old-school and within 15 minutes I had a working replacement using a few lines of PHP and JavaScript code from Google. While it’s not as convenient as a plugin, it works fine with sidebar widgets.

Thanks to tamba2’s excellent (and brief) how-to guide.

Idiosyncracies with anamorphic TIFF image export in Final Cut Pro 6

Published by Eric under Editing, Graphics, Macintosh, VFX

Final Cut ProOur project is shot in DV PAL which has a frame size of 720×576. However, we’re using the footage in anamorphic aspect ratio and discovering that exporting to other formats has interesting side effects.

FCP handles the anamorphic aspect ratio as easily as clicking a checkbox. When exporting a QuickTime movie it will always have a frame size of 720×576 (the native resolution). If you want to create a QT Movie for viewing in anamorphic (1024×576 display size) the footage must be run through Compressor (or QuickTime Conversion) and specify the larger size. It’s not automatically done for you.

The business of handling anamorphic footage is becoming a problem for our visual effects shots. Some artists request TIFF sequences rather than QuickTime Movies and unfortunately TIFF export will render the image in anamorphic’s 1024×576 frame size which produces unwanted artifacts when scaled back down to 720×576.

After some experimentation I discovered the way to force a TIFF export to the native size is unchecking the Anamorphic setting on the clip. Strangely, this produces an image of 768×576 rather than the desired 720×576. Is this OK? I’m waiting for my VFX Supervisor to tell me.

A related bug with TIFF export is the handling of file names. Although Apple warns against the use of special characters in clip file names (i.e.: /, ?, *, etc.) it does nothing to stop you from using them. I haven’t encountered any issues with forward slashes until I began exporting TIFFs. These special characters must be removed during the TIFF export process but QuickTime Movie files are exported without error.

This was observed using FCP 6.02.

Shot detection in Final Cut Pro

Published by Eric under Editing, Macintosh

Final Cut ProFinal Cut Pro 6 has the ability to batch capture DV footage and separate clips by breaks in the time code. It’s far better to burn consistent time code before using a tape (striping or rewinding a bit) but if you’ve inherited media with inconsistent time code you may not realize how FCP handles certain nuances.

Time Code Break

Time code break detection works as expected: a new clip is created at the break, assuming a new shot was intended.

Blank Tape Detection

Suppose you have a DV tape without any time code and you have portions of unrecorded tape (i.e.: black between shots). FCP will treat these blank portions as time code breaks even though there is no time code.

The same is true for media with time code breaks and black breaks.

How Does FCP Assign Missing Time Code?

If your source media is sans time code Final Cut Pro will add its own. I’ve noticed it assigns Hour 12 and higher to such footage although I’m not sure why it chooses that number. This makes it easy to spot in the Browser.

When to buy anything Apple

Published by Eric under Macintosh

Apple logoI wrote about this topic before but it’s worth another post based on the frequency I’m asked about buying a new Mac.

The Mac product line is pretty well structured. The most powerful devices end with the word “Pro” and everything else is a good performer based on your preference of an attached monitor. If you’re a Windows gamer, it’s no contest: you need a Pro model.

However, the more important issue is when to buy your Apple product whether it’s a MacBook, iPod, Cinema Display, or iPhone. Apple releases new and updated products at MacWorld in January and June with product refreshes at points throughout the year.

Apple doesn’t usually change product pricing once a product is released (the first gen iPhone broke this rule) so don’t hold your breath for a cheaper MacBook Pro in June. Instead you’ll get a MacBook Pro with faster CPU, bigger hard drive, multi-touch, or whatever else Apple throws in for the same price as last year’s MacBook Pro.

Back to timing your purchase… Never buy an Apple product within 2-3 months of MacWorld or risk the disappointment of having last year’s feature set and performance. If your circumstance dictates a new device (ie: your MacBook Pro fell into the toilet) then do what’s necessary to get up-and-running.

The best resource for timing your Apple purchase is the MacRumors web site. Their Buyer’s Guide tracks the last product update, news items, and their opinion on when to buy.
