video/movie clip

is there any difference between a movie clip and a video clip please, if so what is it?
i have 1 of each, both around the same length but when burned to disc i uses nearly 4mb of space on the disc the outher only around 1.5

 

mpeg's

 

I'm not very familiar with video stuff but the following seems sensible to me.

If your two mpeg video clips are "identical" in content/time length/size on screen but they consume different amounts space on your hard drive, then I suspect they differ in "sampling rates" (also referred to as "bit rates "). Your media player might display the bit rates for the videos you watch.

• Wikipedia: Sampling rate

You can click on this link to see tables that list various bit rates for audio/video. (I have no familiarity with the software offered there. I only found the site via Google.)

Lower sampling/bit rates will yield smaller files sizes (and lower audio and/or video quality which may or may not be noticeable to you when listening/watching).

I used play with audio editing software years ago. Sampling audio recordings from CD at 8 KHz resulted in a much smaller .wav file size than than recording the same clip at 44.1 KHz (CD quality). Sampling audio at 22 KHz was better quality than 8 KHz but, to my ears, wasn't much worse than 44.1 KHz.

If I recall correctly, recording audio in mono yielded half the file size than recording in stereo too (for the same sampling rate).

 

thanks, the amount of space used is different when i try to burn the files they are almost the same on the hard drive. i was trying to put parts 1 and 2 together on the disc. normally i get 3 films per 4.7 gb disc. thanks for all the help though
