Exporting and final product quality. at DVinfo.net

OK. First of all I have to say I love my new vx2100. It is kind of like getting a new tool and trying to use it on everything in the house the first day. I am shooting everything. I am also stumbling my way through adobe premier. Having fun while I am at it but stumbling non the less. I finally edited my first 30 minute shoot. When I exported it and watched the footage the quality went way down. It is full of jaggies tearing and everything else. I tried to do a search but did not know what to search for. I purchased an adobe handbook but it does not give much detail on how to compress your project without loosing quality. I understand the higher the quality the larger the file. How do I insure the quality of my final product will look as good as possible when it is finally done? If someone could point me to a thread that addresses this or give me some advice I would appreciate it.

Are you watching it on a computer monitor or a TV? Video that is interlaced for TV will have "jaggies" when viewed on a computer monitor. Try exporting the final edit back to the VX2100 (using the dv .avi codec) and watch it on a TV. It'll probably look fine.

Thanks for the quick response. I am watching it on my l 15 inch LCD monitor. I did not know it would have that effect. Do you know of any good books that will give me a crash course on compression and decompression?

The interlacing ("jaggies") aren't a matter of compression, per se. It's a matter of how television sets display an image. If you are creating video to be viewed on a (non-progressive) TV, then interlacing is fine -- that's how TVs work. This is one reason why it is good to have an NTSC monitor (or just a regular ol' TV) when editing for television -- you can see how the video will *really* look, without the interlacing artifacts (jaggies).

If you are creating video for viewing on a computer monitor, such as for the web, then you want to deinterlace it. Premiere has deinterlacing capabilities, and programs like After Effects can help you get an even better deinterlaced image.

What did you want to know about compression? There are probably tons of threads about compression on this site for you to search -- I wouldn't necessarily recommend a book, mainly because you can get a lot of great information for *free* if you search through forums such as this one.

That makes since. Thanks for the links. They will keep me busy for awhile.
