Few video producers have the budget for a custom musical score, or the time/equipment/musical skill to create one themselves, so Sony has released Cinescore 1.0.

Like SmartSound's QuickTracks, Cinescore lets you pick a theme and automatically arranges musical elements - like the intro, verse, chorus, break and finale - to create a custom soundtrack that fits the length of your scene perfectly.

Twenty themes are provided, ranging from wide cinematic audioscapes to tight, punchy soundtracks (with a couple of cheesy numbers for good measure), and further theme packs are on the horizon. Cinescore also comes with a wide selection of audio transitions, too.

Unlike QuickTracks, Cinescore allows for a much greater level of adjustment after the initial track is built. As well as selecting the starting section, mood and arrangement, you can add markers called "Hints" to the timeline, which allow you to tweak Section, Mood, Tempo and Intensity at key points, with a high degree of control.

For instance, Intensity has a sliding percentile scale that lets you adjust how "layered" the music is, with higher values bringing in more instruments. This can be a gradual climb or descent using the Generate setting, or you can use the Linear or Hold switches to hit specific values - to suddenly shift from a 100 per cent, full orchestral movement down to a 15 per cent flute solo, for example.

Altering the Mood setting lets you switch variations for the theme, moving seamlessly between "Live Rhythm Section" and "Massive Party" in the Blizzard of Sparks theme, for example. This can be really useful if you've assigned audio motifs to separate characters and you want the music to shift as the camera switches between their actions.

The degree of customisation available in Cinescore is immense, and it's here that the software struggles with poor interface design. Built on the same front end as Sony Vegas, the customisation takes place in two dialogue boxes, rather than directly on the timeline. Progress is bogged down in trial and error - particularly as the percentage values don't always provide a useful indication of the change that will occur - and it's often impossible to make changes at the exact point you need - which explains why they're called "Hints". The absence of a preview button for transition selection is also an annoying oversight.
