Match Moving Is doing my head in...

Finding it really hard to match move the scenes that I want to use. Especially since they are in war movies. There are so many post production additions such as smoke that make it near impossible to create a 3d scene and match move.. I've tried 2 different programs and nothing seems to go as I plan. Not only that but I need an extremely good copy of most films to be able to match move accurately. Everything I find seems to be too blurry and unusable. I will try and find something with a higher quality to use instead. Fingers crossed.
