Direction of procedures

Post by seostudy2004 »

Hi everyone!

I'd like to get a simple instruction of steps I need to do to complete a change of background music of a video clip (mpeg file). Hope you could give me some guidance.

I have a video clip (not MTV) with a music background, like documentary with background music. However, I want to change that music to another one. This is what I did:

1. Open a new project.
2. Add a video section (the mpeg file).
3. I saw two tracks (video and sound).
4. I delete the sound section.
5. I add a new music (mp3 file) into this sound section.
6. Save a video --- here I did not see "mpeg" as file name, but "avi." But I saw the options underneath that I could choose audio and video format, so I did mp3 and Acroft Mpeg writer.
7. I tried to save this file, but crashed. Program was forced to close.

Please help!

Thanks so much!

I tried again...

and this time I tried to save the combined new files into a video file and save it as WMVideo, but I encountered "Direct X" error. So, I had to save it as Uncompressed Video, and created a really huge file (1.4GB), and the quality is not as good as orignial MPEG.

Please instruct, which is the correct video file to save as? Anyway to save as mpeg?

Thanks again!

If you want to save as AVI, you may need to use the Indeo, Cinepak, or MJPEG video encoders. The best solution is to install the free DivX encoder, which will give better quality and compression than the ones included with Windows.

Thanks Chris.
So DivX will work with Multiquence (3rd party software in their eyes) and will allow me to save video with their format?

DivX should work with most Windows video editing programs. I tested an older version of the encoder in Multiquence a while ago and it worked well.

thanks again, Chris. But I am puzzled by the larger file size after saving as divx 5.21 codec file.
The original is 33M mpeg file, for example, and after I saved (adjust the birate to 2000), it became 52M. Divx suppose to shrink your file to be 1/10 of the orignial size, but I just got bigger ones. :(

even larger file size

Post by seostudy2004 »

after I combine two video clips into one -- certainly it will be larger, but the size is just too large -- 150 MB after I combine two clips of 32MB each. I saved it as divx file, which should be much smaller. Could you figure out any possible reason? I saved it as 2000 birate.

Thanks!!

One of the problems when saving AVI files is that there is currently no way to compress the audio. You can use the Options | Playback command to set the rate to 22050Hz to reduce the amount of space required.

Also use a bitrate lower than 2000kbps. I would guess that something closer to 850kbps would give about the same file size.
