RP40 (SMPTE 35PA) for the picture. Your best bet for sound would probably be the Dolby jiffy film since most of the sound alignment films are of little use without test instruments. How deep is your wallet?------------------

Even a cut up trailer could work for you, of course a still part, like right at the end, dont know what its called, but where the full screen credits come up listing actors/actresses, producer, you should know what i mean, this will show you focus and steadiness. If you want to check for ghosting, a simple Coming Soon still spliced into a loop works well, just frame it to the top and bottom edges of the screen.

A print made on a continuous contact printer can be very steady, if it is "Film Done Right". But the original must be "short pitch" (BH-1866 perforations) and the print film must be "long pitch" (KS-1870 or DH-1870 perforations), and the printer guide rollers and tensions set to specification. When a print is unsteady, it's likely some stage was printed short pitch to short pitch, or the printer was misadjusted. I have seen very steady prints from the highest speed printers, and unsteady prints from very slow printers, so speed is not the key factor.------------------

Trailers are acceptable for quick testing, not aligning, as I did mention, this MUST be a still section like credits, if that loop is perfectly focused accross the screen, then there no problem. Except not too many go to the outter limits of the screen. If you suspect a focus problem, the chances of a lab error ending up with perfect focus on your screen is highly unlikely. And as far as travel ghosts go, all your looking for is white ghosting into black, a coming soon clip (or date) from the end of a trailer is a good test for this. Be sure to frame the loop throughout the whole screen.
