Mac OS: File Stocktaking: Equivalent of TREE (as in DOS)

Saturday, August 11th, 2012

How, on a Mac OS system, to do the equivalent of TREE in DOS:

  • find . -print | sed -e ‘s;[^/]*/;|____;g;s;____|; |;g’
    • And there is much more on ths in the article, including how to add this “command” to user profile.

My crude adaption of it, to list only the main directories in my [Media] area:

  • find . -type d \! -name “BPAV” \! -name “CLPR” \! -name “TAKR” \! -name “929*” -print | sed -e ‘s;[^/]*/;|____;g;s;____|; |;g’
    • Crude but delivered what I wanted.

Disk Space Usage / Inventory

Wednesday, April 21st, 2010

For Mac OS:

  • Disk Inventory X

For Windows:

  • WinDirStat
  • FolderSize

They are both pretty similar, in each case displaying filespace usage via a tree map looking like a patchwork of multicoloured PVC, each colour representing a different type of file (audio, video, application, document etc.).  Their advantage over traditional browser trees is you can see all the largest files and folders simultaneously (as a plan-view).  Tree maps (treemaps) are explained at – they are formed by subdividing in alternate dimensions (horizontal/vertical), each time in proportion to relative size of item, be it folder or file.  A variation on this, employed by the above tools, is a cushion treemap [], where shading reveals the directory structure.  A further variation is the squarified treemap [], where subdivision and grouping attempt (no guarantee of success) to make the rectangles as square as possible.

Home Network

Thursday, January 7th, 2010

Need to establish a better home network, e.g. so Parallels on my Mac can see my Windows laptop, so it can suck the XP out of it.  Also want shared printer etc. (I have a node for that).   Just a question of setting it all up…

FCP iTheatre: play an FCP timeline straight into a chat

Thursday, January 7th, 2010

Geographically separated team members of a Final Cut project can collaborate via iTheatre.   Suppose an editor is discussing with a client via Apple’s iChat.  Then the editor can play out of FCP straight into the iChat session.   It’s in FCP: View > iChat Theatre Preview.


There are some reputable video people covering this topic:


But iChat is only available for Macs.  What if the client doesn’t have a Mac?  I did some googling:

  • iChat is an Instant Messenger.
  • It is only available for Macs but it is compatible with AIM (AOL Instant Messenger), which is available for Windows.
    • ” iChat is only available on OS X” []
  • .mac accounts are just AIM accounts. Enter your .mac username with at the end while configuring an AIM account. []
  • Whatever is playing in your Viewer or Canvas window is sent via iChat to your remote viewer. []
  • But can the iChat Theatre option be used with Windows users?
    • This person believes it is not possible to interact with Windows users (I wonder if they know of the AIM option or whether it handles iTheatre) []
    • “If your collaborators are on Windows and don’t have access to a Mac, you’re out of luck.” []
  • “for iChat Theater Preview to work, both the host and remote computers much be running Mac OS X version 10.5 Leopard or later. Both computers must have iChat accounts and the remote user’s account must be added to the host computer’s buddy list (more detail from Apple here). ” []
  • []
    • “… is it possible to make videoconference between a PC using google video and a MAC using ichat ?”,
      • “No, it is not possible.  Video chat is only between Gmail chat users.” and furthermore “You need … the Newer Version interface of Gmail”
  • It has screen sharing, so both parties can observe and control a single desktop

Some links about iChat itself:

  • iChat itself:
      • Overview and context wrt other Instant Messengers (IMs).
      • Has great list of add-on tools e.g. encryption.
  • How to converse with Windows users
    • []
      • “I wish MSN Messenger was supported natively as hardly anyone I know in the UK uses AIM. I’ve only got 10 AIM buddies. I have to go through a Jabber server with an MSN transport to use it”
      • “I am same as the others. I use Adium as I have MSN and Google Talk friends mostly and very few on AIM.   Sure I can use iChat fo Google Talk”
      • “It seems most of us are using Adium because iChat doesn’t connect to MSN and/or Yahoo Messenger.”
      • “Skype doesn’t intereact with any other software as far as I know but for internet-based phone video calls, it is the best because so many people use it and it is on Windows as well as Mac.”
    • []
      • Adium is what Pidgin should be.
      • Adium is based on Pidgin’s libpurple (libgaim), which is already used in Pidgin on all three platforms.
      • Adium is the Cocoa client of libpurple. Pidgin is the GTK client, finch is the CLI client, etc… Same IM backend, multiple GUIs.
      • “AIM [] is about as close to iChat as you’re gonna get on Windows. That said, a better option would be to go with something more flexible like Pidgin. []”
  • AIM
    • []
      • If you’re using the AIM service, make sure you have port 5190 open on your router, NAT, firewall, cable modem, or DSL modem. You’ll need it open for incoming connections to send and outgoing connections to receive (yes, that is the right way round: the recipient connects to the sender).
  • Pidgin
    • Is open-source, has sometimes debatable deadlines and capabilities.  Many consider Adium better, and it has been stated that they are both front-ends onto the same core.
    • (formerly GAIM) []
    • [] “Pidgin is a chat program which lets you log in to accounts on multiple chat networks simultaneously. This means that you can be chatting with friends on MSN, talking to a friend on Google Talk, and sitting in a Yahoo chat room all at the same time.  Pidgin runs on Windows, Linux, and other UNIX operating systems”
    • There are third-party plugins for other protocols such as Skype and Twitter.

Codecs for Mac/PC/linux & FCP/Avid transfer

Wednesday, December 23rd, 2009

Eugenia recommended ([] as of September 2008) DNxHD and ProRes, among other codecs, for transfer between PC and Mac.   She also advises Lagarith for transfer to/from linux, though it sounds slightly tricky.According to BobRusso (Applications Specialist at Avid) []:<<< 

You can install the ProRes decoder on a system without FCP:


Make sure you have the latest version of the Avid codecs. They can be downloaded here:

I suggest using MPEG Streamclip to convert the files:



Ubuntu Studio

Wednesday, December 23rd, 2009

Just wondered what was happening video-wise in the linux world, for example how was Cinelerra going.  Last I looked (months or a year ago) it was possible to get Cinelerra working under Ubuntu.  So when I came across UbuntuStudio, I thought it was worth checking out, just to keep abreast of developments.


However it appears not to include Cinelerra, instead OpenMovieEditor


From []: 



  • openmovieeditor – Video editor
  • ffmpeg – Multimedia player, server and encoder
  • ffmpeg2theora – Theora video encoder using ffmpeg
  • kino – A non-linear editor for Digital Video data
  • stopmotion – A program for creating stop motion animation.
  • dvgrab – Grab digital video data via IEEE1394 links

It is only available as an Installer, not LiveCD [] . For more info:
