Sony Vegas: Audio but no video from iPhone?

I recorded multiple clips from my iPhone 4s and imported them, edited them and completed my movie although when I render the video into any format it only plays my title and maybe the first clip (only in quicktime) and then the rest of the film is in black with only audio playing in the background. What can I do to render it and play it completely? I'm currently using Sony Vegas 12.

Why won't my music sync to my iphone?

I have 400 something songs on my phone and laptop from a mixture of itunes and websites or whatever, and i downloaded some more from a site onto my laptop. I put them in a folder and added the folder to my itunes library.everything showed up and looked fine, but when i try to sync my phone to add the new music to my phone it says that everything will be erased and only the new 49 songs will be on there. I did it anyway and now my phone as 71 songs. The 49 new ones plus my most recent others for some reason.except only the 49 new ones will play, my phone skips over the others. All of the songs are still on my computer but i don't know how to get them all on my phone. I also tried backing up my phone and then redoing it, but it just wasted time.

Is eating less than 1000 calories a day bad?

I'm a 15 year old girl, 5'6, 130 lbs and almost a month ago I decided to start eating healthier. I cut out all wheat products and dairy(I'm lactose intolerant). I feel really good and have lost 8 pounds so far. On a daily basis I eat fruits, veggies, nuts, rice products, and meat. I count my calories on this iPhone app because I tend to over eat when I'm bored so I decided to keep track and make sure I don't go over 1, 300. But on most days I find that I don't go anywhere near that number. I do eat a lot. 3 meals, and lots of snacks but they're all low in calories because of my new eating habits. On the days where I don't eat lots of rice products and nuts, I don't go over 1000 calories, even without exercising. I exercise 6-7 days a week. I burn 250-300 calories at the gym every time I go. Physically, I feel great and healthy but I want more opinions to see if this is healthy for me or not. Should I be eating more? What do you guys suggest?
