There are a lot of different software tools, plugins and stock footage packs I use for my film and visual effects projects. While there might be a few items that I forgot to mention, the list below contains pretty much everything I use on a fairly regular basis.
Probably the best known powerhouse for image editing, it provides all you need to layer, clone, blend, paint, process, correct and otherwise modify your images. I've used it to remove objects from my scene or create entire landscapes using the clone stamp and a few photos I took in different locations.
Badly recorded audio will generally remain badly recorded audio and you can't push the noise removal in Adobe Audition too far or it will start sounding rather electronic and unnatural. However, for most of my basic audio noise removal needs this tool is a life saver.
I am not a fan of the Adobe Creative Cloud Manager as it's a bit like iTunes: a necessary evil to get to the great software it contains, but I am a fan of having all of Adobe's tools accessible directly via the internet at the click of a button.
I have always struggled to find good free gun and fighting sounds and I think I'm sorted since I got my hands on those packs. They contain a huge amount of great sounding effects and Triune Stores offers these packs in all sorts of different shapes and sizes so you can pick the one that fits your budget.
Cubase, like any other fully fledged DAW, is not an easy tool to learn, but it provides me with much more flexibility and control than editing my audio in Adobe Premiere or Audition.
Since I admit that this might be due to my lack of skill in using Cinema 4D, I recommend giving the free Lite version a try to see if you like its workflow and rendering engine.
