I get plenty of errors with QTs with bbox not set etc. I would convert once and
be done with them.

avoiding Quicktimes is still the best policy. On both OSX and Windows, Nuke
relies on a separate “helper” process to (presumably) handle encoding/decoding,
and I cannot count the number of times this helper process has gone off the
reservation and frozen Nuke (presumably while it’s waiting for a response of
some kind). There are even certain combinations of upstream nodes that can be
used to reliably break the helper when executing a Write.

(especially if they’re coming through a ProRes intermediate). EXR doesn’t
compress noise/grain well in ZIPS mode (since the compressed blocks are so
narrow), so the file size difference is usually fairly negligible, and you’re
still looking at the CPU decompression overhead on top of that.

> Hey all - we typically pull our plates from the above files and
output to dpx files for compositing. Someone here has been pushing for
just using the original quicktimes directly in comp(we've gotten a fix from the
latest release notes that addresses a subtle colour shift between nuke and
compressor). Apart from the arguments about speed(we found in the end it's
actually pretty similar) and workflow(head in and out and the rest we can
probably handle), it struck me that stability is a potential problem.
We're running windows here(win7 64 bit), and I was able to make some quicktime
crashes pretty trivially with Nuke 6.3v4 through 7.0v8(same triggers, same
crash, which suggests the issue is with quicktime).

works - just wondering if anyone here has done this with any success or wildly
wave their hands saying 'nooooooo!'.
