Useful tools for homebrew media – my OS X workflow

As I’m sure regular readers are aware, I’m producing a wider range of media than ever before, now that I’m a regular podcaster and creating a range of video content as well. I thought it would be useful to talk a little about the range of tools that I’m using – far from professional level Final Cut or anything!


The hardware is pretty varied. The core of the whole “system” is the MacBook Pro, which I use for pretty much all of my editing. That also has the iSight camera, which is adequate for videos which need to include my face, although I’d like something higher quality (any recommendations?). I’ve mentioned iGlasses before, which is useful for adjusting the iSight input. From an audio perspective I use a USB headset and also a Blue Snowflake USB microphone, which is absolutely great – compact, convenient, and it captures excellent quality sound.

If I need to capture video away from the computer, my current camcorder of choice is the Kodak Zi6 which can take HD 720p footage, albeit at a quality limited by the rest of the hardware (lens, sensor etc). I’ve yet to do a proper review of this, but as far as I’m concerned it’s a step up from either the Flip Mino or the older disgo Video Plus which I’d tried. I also sometimes grab snippets of video on my compact Canon camera.


For screencasts I use ScreenFlow. This is just a wonderful piece of software which is capable of recording both the screen, and from the iSight simultaneously. This allows the video to be overlaid into the screencast if required, so you can personally narrate what is going on. Even better than that, ScreenFlow lets you zoom in on windows and desktop features, and is really a general purpose compositing application… if you look at this video I made when I talked to a friend recently, you’ll see there are no desktop elements at all, just the video stream from the camera, a picture of him, and the audio, with some nice image tilt and reflection effects applied. ScreenFlow has also recently added text annotation features, which are really useful.

I’ve yet to use it for any practical purpose, but I also just downloaded OmniDazzle, which is now free. OmniDazzle lets you highlight areas of the screen with visual effects using a single keystroke – I can see this being useful in combination with ScreenFlow in the future.

Video editing

A few weeks ago I blogged about iMovie 09. I know a lot of people really dislike both iMovie 08 and 09, but I’m totally comfortable with both versions now, and I have to say that 09 is just beautiful. I’ve had no issues with it – it’s great for rapidly mixing and editing video, still images and audio. Watch my introductory series on YouTube or the whole thing as one movie on Viddler. I wrote a bit more about my use of iMovie back in December, too.

Here’s a tip: have you ever wanted to create some animated titles of your own? I have one word for you – Keynote! When I created the Home Camp TV title sequence it was a simple matter of creating a slide with some animated elements in Keynote, and exporting it as a Quicktime movie (which I did without sound, allowing me to overlay a choice of audio on the title sequence in iMovie). It’s great for quickly creating JPEG stills with text for titles, too.

In terms of finding audio to accompany videos… I’ve used both the pre-canned loops that come with iMovie, and also used some audio from Podsafe Audio. I do find that site a bit cumbersome to search though, so I’d be interested to know of any other useful, royalty-free resources.

Audio editing

I’ve not done a great deal on the audio-only side of things, but my essential tools here are Audacity for editing and cleanup; and Levelator for post-processing. That’s a really important point, by the way: only levelate your audio once everything is mixed together, the whole point is that it’s going to analyze everything and modulate the volume equally… if you have a bunch of snippets of audio and levelate them separately, then edit them together, you may well still end up with volume variations.

Another quick tip at this stage: to avoid issues with VBR MP3s showing up as weird (and incorrect) lengths in some tools, I bring the audio file into iTunes and do the MP3 export in there.


For “proper” RAW photo editing and management, regular readers will know that I’m a huge fan of Lightroom. I use Pixelmator for finer adjustments on exported images.

Beyond that, I find that iPhoto is useful for quickly grabbing snapshots from the digital compact camera for compositing into iMovie clips. Skitch and LittleSnapper are both very useful tools as well as they enable me to rapidly take, resize and annotate screenshots or clips of web pages. For diagrams and so forth, there’s nothing that can beat OmniGraffle.


Finally, a couple of other useful bits and pieces. Transcoding to different formats is through either VisualHub (now defunct) or ffmpegX. QuickTime Pro is an essential (and highly cost-effective) upgrade too, since it lets you make very quick edits to QuickTime movie files and control the output format more finely.

There. Now, I imagine this may attract a range of “have you heard of…?” “why aren’t you using…?” and other responses, but that’s how I’ve currently settled things. Hopefully some of the tips and thoughts here will be useful to other amateur content creators, too! 🙂


An example of the value of Twittering

Tara Hunt has posted a great piece recently on Twitter for companies (by the way, if you don’t follow Tara’s blog, you really should take a look). Here’s a a small illustrative anecdote from WSTC last week.

I gave a presentation at our internal WebSphere conference that talked about Twitter, among other things (ordinarily I’d Slideshare the presentation, but it did contain some stuff I can’t post externally, sorry about that… maybe I’ll write an external version sometime).

One slight technical hitch. The conference organisers were set up to record presentations from a Windows laptop and Powerpoint using Camtasia. I was presenting using Keynote on the Mac, so I chose to use ScreenFlow to record the session (I noticed that Jason McGee did the same thing for his WebSphere sMash pitch earlier in the week). I tested beforehand and everything seemed good, but just at the end I switched virtual desktops to do an unscripted demo of something, and found a stack dump from ScreenFlow on the screen. I’d spoken for an hour, taken 15 minutes of questions… and lost the lot.

I twittered my frustration and headed out into the corridor, thinking about re-recording.
Within minutes, I checked my email and found an email offering support from one of the guys at Vara Software, who produce ScreenFlow.

Well there’s yet another illustration of the power of Twitter. Let’s be clear, they haven’t in fact been able to recover the data for me, but that doesn’t matter… this level of responsiveness and support just makes the relationship I have to that particular piece of software much more positive and sticky. I’m pretty impressed. I assume that they were using Tweetscan or Summize (Twitter mashups / “search engines”) to watch for references to their software and decide whether to respond. This was just great.

Oh, and this worked brilliantly to illustrate my point about why folks should take a look (or second look) at Twitter in the talk itself. This is increasingly becoming an important channel of communication.
