I imported a video into Motion that was 363 MB....all I did to it was add 30 shapes (circles) overlayed for 1 second each at various points in the vdieo. When I "exported" the movie it is NOW 5.7 GB....I exported it in the same file format/resolution as the original I had edited in Motion.
Why is it so large? What can I do when I export to have it not be so large yet retain the same resolution?
iMovie '11, OS X Mountain Lion
I did not "knowingly" change any codecs....I simply exported it...I assume at the same resolution as prior...1280x720....color profile (on Get Info) is HD (1-1-1)...duration is only 4 minutes 48 seconds.
When you use the "Export Movie" option the first setting in the export window is the codec. Even though it says "Same as Source" all projects default to ProRes 4444, even if you have another codec in your project for one of the clips. Basicly the default, a lossless codec with Color and Alpha, this will create a much larger file. If you want a smaller file you may need to switch to another codec from the Export menu. Since you didn't indicate what your original format was (HDV, H.264, ProRes 422, etc) I can't tell you what setting is right, but H.264 will be smallest, but is not lossless.
When I go to Get Info about the file, it says:
Size: 368.3 MB
Dimensions: 1280x720
Codecs: h.264, AAC
Color profile: HD (1-1-1)
Duration: 04:48
Audio channels: 2
When I edited the file in Motion and then saved it the file became 5.8 GB!
Understood. Like I said, your original file is H.264, but the default export (I can only assume that's what you used first) is ProRes 4444. You need to change the Export setting from "Same as Source" to "H.264".
What codec did you use? What you are describing sounds like you changed codecs, maybe from H.264 to ProRes 4444?
