    Mushrooming files on import!

    Hi, I'm currently importing mp4 files into Avid and for some reason they're taking up a HUGE amount of space (much larger than the original files).  What's going on here?  I'm concerned that I may run out of computer space.  In addition, once I've created a timeline and  after rendering special effects, if it's a huge file, how do I export it?  I think it would be too big for even a DVD.  Help please!

    Hi,

    What format/frame rate are the mp4 files, what format/frame rate is your project, and what resolution are you using when you import?

    How long is the sequence?

    Re: Mushrooming files on import!

    When you import, the MP4s are transcoded to DNxHD (or DNxHR, depending on the project settings). These are far less compressed and so take up a lot more space. Linking to the MP4s uses the files natively; no transcoding required. But playback performance may suffer, depending on exactly which format of MP4 was used (if you're forced to use the QuickTime plug-in, performance suffers).
