So I read that handbrake is the best video converter for iPhone 4 to keep the widescreen video format. I've tried everything to make it work, but it just doesn't want to cooperate for me, so maybe someone can help: I have an iPhone 4, and I'm trying to keep my "HD-ness" in the iphone 4's display, so I'm using handbrake to convert. I've tried converting an MKV, an XVID AVI, and a standard AVI, and all three output the video fine, but the audio is stripped from the mp4 that comes out, and the video plays silent on my mac and my iPhone. Any ideas as to what I'm doing wrong? If there's a better program or way to do this please let me know. Ideally free. Ideally designed for iPhone 4's resolution. Thanks as always!
