Hi people,

I just installed EMC 10 and it seems to work fine on this old computer of mine. ( an AMD XP 1.4 with 2Gb RAM and All In Wonder Pro 128 )

So my first task is that I need to open an AVI file that I recorded with my little palm sized camcorder, increase the brightness a little, then save it as an AVI file with that same name again.

I managed to open it and change the brightness, that part is fine, but I can't for the life of me figure out how to save it again as an AVI file, so my brightness changes are saved.

Later on in the evening: I found out that I had to first save it as a project, then it would allow me to export it to an AVI file format, BUT doing that takes a 1.8 meg AVI file and turns it into a 200 meg AVI file with my changes in brightness.

What the...?

You do not have to Save…

There are 2 ways to reach your goal, either use the Menu selection under File or use the Icon. For either one the option you want is:

Output As



As far as the change in file size it is actually a change in Quality. I am guessing your camcorder is set to very low quality or may not be capable of recording DVD Quality (720 X 480). Load your Raw clip into VW and right click on it to check the Properties. Also check your camcorder owners manual.

VW only offers one AVI quality setting for output.

You could choose another file type, but it would be better to know what you intend to do with these files before making wild guesses for you.

Actually I'm using one of these for field investigative work:

So it's not a large picture, but it's adequate for what I want and need.

But I absolutely need to keep the small file size after adjusting the brightness or whatever and there seems no reason why this program has to expand the file size on me by 200-300 times.

The size gets changed because of the format you selected.
A 200 meg avi file is small Why do absolutely need to keep a small file size? What do you intend to do with it?

Try ouputting to General AVI, normal size. That seems to give the same resolution (320x24) and 25fps as your camera

AVI files normally hold compressed video, which is why you need a decompressor to view or manipulate them. It looks as if you are saving yours as uncompressed AVI which would explain the relatively large size of the file.

I'm keeping video records of my serves, in case someone attacks me or denies they were served.  

And making a 1.8 meg file into 200-300 megs is just insane. I don't have infinite HD space for that. Who does?

Ok, so how do I store them as compressed AVI?

The video you are using is already very highly compressed

I told you above how to create the "small" video file.

Only 2GB free? You will not be able to do much video work on your computer with that amount of space. Its time to invest in a larger (500GB), perhaps external, hard drive.

[Brendon]

If your source AVI was 1.8 MB and your output is 200-300 MB then it needs to be recompressed. Try this and see if it does the trick.

Select the Video Guide from the Home menu, and Convert Video. That brings up Video Copy and Convert.
Select "Video compilation" and click on "Add Movies" Then navigate to where you have your source [big] AVI and select that.
Now on the destination side of the application select DivX and output to file/folder
Click "Save As" above that destination box and choose where you want your output file saved - somewhere different from where your source file is
Click OK, and the source AVI should be converted to a DivX compressed output AVI file.

p.s.


I tried this with a half-meg 3-second compressed AVI. When saved uncompressed it became 24.7 MB, but when put through the converter above it came out as 486 kB again.

I'm painfully aware of that.  

When I can get enough time to clean up this office, I plan on getting a whole new computer, with 250GB or so SATA drives and the latest dual core goodies etc.

Thanks Brendon.

I'll have to try that when I get a little time, I'm swamped at the moment, but it sounds like it should work.

The writers may want to consider a one-step solution for that, for future updates?

So, did you try what I suggested, Melissa?

Yes, just now, and thank you Brendon. It seems to have worked very nicely.

I actually tried it with a vob file and sent it to an avi file.

It took a 112 meg vob and made a nice 19 meg avi.

This afternoon I caught our baby lovebird Sam playing with his head inside a bell. Look!

LOL!

[Brendon]

Excellent!  That's the idea of DivX, to give you very good video with a very small file size.

Ouch!  Sam!!  Doesn't that shouting with his head inside the bell give him a headache??

I don't know. People use drugs for tripping, maybe birds use bells.
