Special characters in DaVinci Resolve bin names cause contents to disappear

There's a bug in the DaVinci Resolve 12 beta that can cause the contents of a bin to disappear if certain characters are used in the bin name. What makes it particularly concerning is that there is no indication that anything is amiss until the project is loaded again, so it is easy to lose hours of work this way.

And because the bug only occurs when a project is reloaded, you cannot load up an autosave to get the clips back either.

Here's how to reproduce it:

1. Create a new bin with a forward slash in the name, e.g. "1 / 2".

2. Drag some clips into it.

3. Save the project and close Resolve.

4. Reopen Resolve. The bin will now be called "1" (everything after the forward slash is omitted) and will be completely empty.

It's worth noting that the clips and sequences do not appear to actually be removed, just hidden. You can verify this by attempting to create a new sequence with the same name as one that disappeared, only to be told that a sequence of that name already exists.

I have not however been able to come up with a strategy for unhiding the bin contents again - renaming the bin back to the old name did not restore the clips. If anyone can come up with a way of doing this I'd be very interested to hear it.

OS X 10.9 network hanging bug

When copying certain files to a network volume on OS X 10.9, Finder (or indeed Path Finder) will copy the first 12 KB and then beachball for minutes before eventually completing the transfer.

Our testing has indicated that this seems to occur when overwriting files from a local disk to the network volume and seems to only occur with .app application bundles. We believe this may be something to do with resource forks because it is rare for files other than applications to have them and network volumes do not support them. It does not occur on file transfers between the same network drive or from one network drive to another.

It's a nasty bug because it not only causes Finder to hang for minutes but can also affect all other applications using files on that volume. It has even a couple of times completely prevented any network or internet access at all for the duration of the file transfer.

We've reported this to Apple and are waiting on a fix. In the meantime, the easiest way is to either delete the destination file and then copy it or compress the .app bundle, copy it and then decompress.

Bugs of the Week - 10-20-13

Here's another installment of bugs in your NLE you should know about.


Premiere will crash if you adjust the border on a wipe transition

Contiguous clips in an EDL will be imported without cuts (Avid has this behavior too but FCP 7 doesn't)

Media files corrupted by "Write XMP ID to Files on Import" feature (I always switch this off - it's damaged too many files to risk it)

Durations are wrong, nests must be pre-rendered

Crash when importing multichannel AVI files created by Blackmagic Media Express

TickTime error can occur on media where Interpret Footage is activated

It's better to license CS6 and CC on different Adobe IDs


Bins in subfolders move about as you navigate the project

Media creation setting not sticking for NTSC projects

Splitting stereo audio to dual mono may result in two A1 tracks

Background processing may not work if your DNS setup is incorrect

Perian can cause files to fail transcoding

Putting a blur filter on interlaced footage softens it, even if the blur is set to 0%. Softening also occurs in progressive but it's much less noticeable (thanks Andy).


When cutting multicam, switching angles after adding a 3rd party transition will cause a cut at the end of the transition and the rest of the clip will revert to a normal clip type. (from Strypes)
