Don't use \fad on fades to black

Dear typesetters,

I have seen this countless times. Every time, it has bothered me. Please, don't do it anymore.

When the screen fades to black (or white, or any other solid colour, for that matter), DON'T use the \fad tag to fade the text along with it. When you use \fad, you're making the text translucent, and not darker. The result is that it will blend with the background - including all the usual associated bugs if you have borders and shadows - and get somewhat darker because the background itself is getting darker - it just won't get as dark as it SHOULD be, and the visual effect is that the text is getting brighter, relative to the background.




Original
With \fad
With \t(\c)


As you can see above, the CORRECT way to deal with this is by using \t to animate the colour (all relevant ones) to black (or whichever colour the screen is fading to). Also note that the background can be seen through the text in the \fad() case, which is not the correct behavior.

Keep in mind, though, \t(\c) is significantly slower than \fad() on VSFilter, so you might have softsub issues, depending on how complex is your text.

  1. Of course the same also applies to fading to white or any other solid colour screen... but it can't be applied to cross-fades where you'll have to do with looking a bit ugly.

  2. okay since this post i've since more than one person not willing to use colour fades because of this post so i'd like to point out that it is perfectly fine to use for softsubbing and anything above a p3 should play it just fine

  5. What to look out for in the example pictures is the lightness of the white fill in the text, compared to the lightness of the bright background.
    Those are clearly different on the two pictures, and the lightness of the text matches the lightness of the background much better on the \t(\c) one than on the \fad one. (Compare to the sample before the fade, the fill of the text and the background are about the same lightness.)

  6. He was not alone. “By 1860 there were 600 watchmakers and more than 40 families in Fleurier making watches for the Chinese,” said Michel Parmigiani, the founder Longchamp Bag and owner of the watch company Parmigiani Fleurier. “The town had the largest concentration of millionaires in Switzerland.”By the 1970s, things had changed. The arrival of the quartz watch was so catastrophic that local people still refer Michael Kors Handbags to it simply as The Crisis. Factories closed, residents moved, businesses shuttered.“People laughed at me back then when I said I wanted to be a watchmaker,” said Benoît Conrath, now 53 and working at Parmigiani. “Back then, Coach Outlet to be a watchmaker was to be unemployed. No one wanted mechanical watches. It was like using a horse and cart to travel.”It was Mr. Parmigiani who came to the rescue. He had grown up in a Coach Handbags neighboring village, graduated from Fleurier’s watch school and had his own workshop specializing in restoration. (He briefly owned Bovet, in 1989-1990.) Then in 1996, bucking the quartz trend, he decided to make his own watches, and to Coach Purses do so in Fleurier.Parmigiani Fleurier was established with headquarters in a mansion formerly owned by the Vaucher family. Vaucher, which now makes watch components, began making parts for the new company. That same year, Mr. Parmigiani persuaded Michael Kors Chopard to base its watchmaking in Fleurier. The town’s revival had begun.“People would stop him on the street and thank him,” recalled Mr. Parmigiani’s daughter, Anne-Laure.Then, Mr. Conrath said, a backlash began against quartz watches. “In the Coach Outlet Store 1990s people realized that a watch was not just an instant instrument, but a luxury product,” he said. “German and Italian journalists realized how beautiful a mechanical watch is and started writing about them.“They saved the watchmaking coach factory store industry in Switzerland,” Mr. Conrath continued. “The watchmaking school in La Chaux-de-Fonds, which was in danger of closing, is now turning away students.”In addition to scores of independent specialists, working on their own or under contract to Michael Kors Outlet the larger local companies, Fleurier also has its own watchmaking quality control center. It was founded in 2004 by the four local companies to establish standards and to certify watch quality, and it operates in Bovet’s former michael kors outlet clearance
