Are exported files supposed to be so large?

Aug 27, 2013 8:29 PM

I recently completed my first video project using Premiere Pro CS5. (I had used iMovie before.) The video runs apprx 45 mins in length and I used at least two layers at all times with up to as many as 4. Every clip was scaled up to 600% as I didn't know what the output size would be like and I was under a slight time crunch. The finished/exported file was 9.69 GB!!! Is there a way to flatten layers (like in Illustrator or Photoshop), compress the file or anything else to make finished file smaller. I'm thinking scaling everything up to 600% might have been a big reason file was so large. Any info or input is welcome.

    What are you editing, and what is your output codec?

    Hi Sanders29,


    in MediaEncoder you can choose the codec you want it to use. Codecs like h264 give you smaller files with high compression. By adjusting the data rate you can

    control the quality and the size of the project. There is also a filesize caluclator that estimates the file size in the media encoder and it adjusts to the data rate you


    If you want to burn it on a DVD you can also chose the right codec and container which would be an mpeg2 (video) and ac3 (audio). This usually lets you select

    an option with "best for 60/90/120mins of video". Or you can adjust the data rate to the max. DVD capacity.


    The scaling or multi layering is not a problem for the file size of the final output. Everything will be rendered to one video and audiostream (unless you export Stero or 5.1 Audio).


    I reckon that the problem is the length of the video. 45mins is quite long so you might have to split the film on 2 DVDs or a double layer DVD if you want better image quality.


    If this was recorded on a A520 digital you probably have 1920x1080 resolution? why did you size it up to 600%? This results in a huge quality loss!

    Please give more information about the conversion to AVI and resolutions you use to edit (sequence settings) and the original resolutions of the files.
