I'm new to video editing and I have Sony Vegas and Adobe Premiere available for me to use. I had problems in Vegas when deleting parts of a video clip (the first few frames of the remaining video would freeze/stutter), and in Premiere I'm also having problems. I've tried finding information about the possible causes and have narrowed it down to the fact that the video I'm using is compressed avi (using xvid or divx codecs). Apparently using compressed video for editing causes a range of problems and the best thing to do is use DV or 'Lossless AVI' as the standard format.
Is this correct, and if so what methods/software should I use to convert my videos? I've tried using 'Super' to convert to avi using 'DV Digital Video' as the codec but the available options were limited and as a result the aspect ratio was severely modified.
Thanks for any help you can give me :)
