Does QuickTime support long file names?

The nominal maximum path length should be 255, but QTML actually fails on paths longer than 253 (I suspect it’s allowing for a drive letter at some level in the code). Don’t bother using short (8.3) pathnames to try to get around this; they aren’t always created, and anyway QT’s canonicalization code also expands the short names. You run into similar heartache with pathnames containing international characters. The only stable solution, which is quite a headache, is to temporarily create your files in a temp directory near the root, then move them to the destination after you’ve written to them with the QT API. This works for outputting movies, but loading them is also problematic; you could move them to a temp directory, but you might not have the privs to do so, and if you created a movie referencing your temp copy, it’s ve
