This is my first movie made in Vision Lab Studio.

I use a Samsung L830 digital camera for my movies for now, since I don't have a proffesional video cam yet wink

Getting to the point, I made a 1 -minute long film of me "shooting" a gun and swinging around a lightsaber, which I later edited in Vision Lab Studio. The original file was about 4 MB, 800x600 in resolution, yet after I saved it in both .AVI and .MOV the file turns out to be over 700 MB! That's a way too big file size! I reinstalled all my video codecs but something is still wrong, 700 MB is way too big for a 1-minute long movie!! Now I can't brag to my friends about it because it won't fit on my pendrive! wink and it takes up a lot of space on my disk, too!

Will somebody please help me!?

I'm certainly no expert, but I suggest you re-render it in your NLE, not in VisionLab. I use Vegas Pro and I know I can reduce the size of a clip by re-rendering it.

It is very odd, though, that a 4mb clip would render that large. Maybe some of the experts can help you sort through this better than I.

You may have your render settings at "uncompressed"

No, it's perfectly normal. Uncompressed video files are supposed to be huge. Just compress it if you need a 'travel' version.

To clarify a bit from what has already been said, the reason your file is so big is that it is uncompressed. This is a good thing in terms of quality, but as you have noted, the file sizes are quite large. That is the reason that lots of different companies have created lots of different codecs that use many different methods to compress your movie into a smaller file.

As a rule, codecs make your file smaller by throwing away some data; in the case of video, various amounts of the color information from each frame are cut out and thrown away to make the files smaller. Due to the clever methods they use to do this, after a single compression you often won't notice a significant difference in quality. But if you do this repeatedly, such as happens during editing when you have to swap files between programs for effects work/compositing/grading/etc., each time info is thrown out while saving the file the quality starts to degrade.

There are exceptions to this, of course, as there are a few codecs that are lossless. In other words, they don't discard any info, yet are still able to compress the files somewhat. You won't see nearly as small of files from these codecs, but they are still noticeably reduced from the uncompressed file sizes. In your case, the solution to your problem is to select a different codec when you render from VisionLab. Quicktime Animation is an example of a lossless codec, good for use during the editing process, but as a final distribution codec, to create a movie that you can play for your friends, you will probably want something with higher compression, such as h.264 or mpeg-4.

One second... thanks for all the replies but I sitll don't know HOW to make it smaller.... I mean there's no option in the program as far as I'm concerned?

In that case, what do I do to make a "travel" version like the h.264 or mpeg-4?

That is exactly how you make it smaller. Select a different codec. Unless you are running an ancient version of the software, this is pretty straightforward. You are running the latest version, downloaded from this site, yes?

Click on render, in 'Save as type', select the desired format then, on the last pop-up box headed 'export video settings', change the compressor from 'uncompressed' to 'DV Video encoder' and see if that sorts it.

Hope that helps.
