I have a Galaxy S2 and have difficulty editing the files on my phone. I want to edit the video files on my Windows 7 PC. I can do this at present using the free Windows Live Movie Maker - but this insists on converting them into .wmv files, and seems to reduce the quality significantly. I have tried and failed with VirtualDub & some other Open Source software. I want to edit these files in their native .mp4 format. Does anyone know of any normal software that I can buy (preferably from Amazon) to do this 'out of the box'? For example would Adobe Premiere Elements 9 support this particular flavour of .mp4? Which of the normal Windows video editing software applications are known to successfully edit Galaxy S2 video? All advice gratefully accepted.
