用 dc 拍了一段 mpeg4 的片，但 1 分幾鐘的片已經有 20 多 mb。
請問有沒有 software 可以 convert 為其他較細的檔案呢？

mpeg4 file size is already the smallest. Is'nt it ?

If you use motion jpeg, the file size may as large as 140 MB.

Sure, but not from the quality (while MP4 is smallest enough), you can consider
1. convert it to small size.
e.g. original 240x320 change to 160x240 something like that.
2. Lower frame rate.
e.g. change it from 25f/sec to 15f/sec or 9f/sec.....
