Modul8 has been one of the premier VJ applications for Mac OSX since version 2.0. Following is a review based on extensive use up to the latest version, which as of this review stands at 2.5.2.
Pros

• Ability to use native OpenGL Core Image and FreeFrame plugins.
• Extensible, highly-programmable user interface.
• Excellent keyboard and MIDI mapping.
• Can use multiple video cards to span video across multiple screens.
• Good learning curve.
• Plenty of preview options.
• Frame-accurate rendering to disk.

After a long wait we have finally received a very good xmas present: version 2.5 of modul8 has been released yesterday, and I can confidently say it's a corker.
Where to start? Well, let's look deep into the core of the new version.
The main engine has been completely rewritten to take full advantage of Tiger's CoreVideo technology. This has improved performance A LOT, even on my lowly iBook G4.

Veejay is a visual instrument and realtime video sampler It allows you to "play" the video like you would play a piano. While playing, you can record the resulting video directly to disk (video sampling).
Veejay can be used to manipulate video in a realtime environment for visual performances and/or for (automated) interactive video installations.

Veejay has the following powerfull features:

• While playing, you can record the resulting video directly to disk (video sampling)

UPDATE: new version ES-X 1.2 released
Here we go: ES-X 1.2 for Mac and Windows has been released, so its time to take a look at the new features and to bring this review up to date. Videokonferenz has brought some very usefull additions into this new version without breaking the paradigm of ESX - flexibility and ease of use. Many of the bugs present in the 1st version have been fixed and the performance has been improved dramatically.

So what's new?

My absolute favorite is the new live video input with frame buffer of 160 frames:

Modul8 offers ten fully adjustable and scalable layers to composite and position in a variety of different ways. The best thing about Modul8 is that its geared towards transparency and ease of use. It wants to be instrumental and based on playing, not thinking. I enjoy mixing with Modul8, not just the end result, I dig the process of getting there, too.

Built on the concept of a DJ mixer, this VJ application is appealing to people that have been looking for a simple and functional program but have been left in the cold by other softwares which include more functionality than is required. Bursting onto the forums only a matter of weeks ago, completely free, courtesy of its creator VJ fader, this nifty MAX/Jitter created Cross platform application is getting heads nodding and outputs cranking.

I don't know how many of you actually purchased MD3 but if MD4 is anything to go by, then don't be too seduced too early by the amazing packaging. Digitalstage have employed some nifty art graphic bods and I love the presentation, in fact maybe the packaging is too sexy! I spent too much time with the stickers, free demo dvd and posters which suggests this is no deep profesional tool....style over content? Should you be worried? Read on.
