    • This includes DVDs or BluRays you own. Even if you own the DVD or BluRay, it is still technically illegal under the DMCA to break the encryption. While some may argue otherwise, until the law is rewritten or the US Supreme Court strikes it down, we will adhere to the current intent of the law.

iMovie problems.

Okay, bear with me, this may just be me being the newbie of iMovie but anyway, I am a frequent youtube user, I have my own account and I am a big fan of the Sims 3 series. When another youtuber gave me the inspiration to start making my own sims 3 videos I was really interested. Then, I started finding difficulty of getting the videos I had created onto youtube. But then, today, as I realized the SAME youtuber uses iMovie to edit and sort his videos the problem of not being able to upload it to youtube went away, because I knew I could import my videos onto iMovie - This is where my problem arose. I had the saved videos in a folder on my computer, but - these files were .avi files. Which, I soon realized weren't compatible with iMovie, because when I tried to open the file, it didn't give me the option to.

So, what it all boils down to is, does anybody know a website that you can convert your files. Also, which file extensions do Youtube and iMovie accept? After looking around Yahoo Answers and Wikianswers, most people were saying it was .mp4

- iMaisie.


iMovie accepts *certain kinds* of AVI files, but AVI is a container not a codec, so who knows what codecs are being used by that file.

I would suggest converting the videos to MP4, which iMovie likes fine. Once you're done editing, the built-in YouTube uploader in iMovie will set the movie to your options for high quality.

Look into Handbrake to convert the movie files. It should be able to convert those files for you with ease.
