Hi, I want to record screencasts on my MAC. I'm planning to use my external screen which has 1920x1080 solution. I have the iShowu application to record. I reduced its frame rate to 4 since I believe it still creates good quality movies with small file size. Here are my problems: When I upload the movie to Youtube the result is a movie with horrible quality. My aim is to embed the video using Longtail's FLV player. ( I use visualhub as a converter ) But then I don't know what people with smaller screen resolution will see when they start watching the videos created with 1920x1080 .
