images quality degrade after exporting

[akuonie]

1. I have tried many times exporting and switching between compressors, but the images quality keeps degrading from the original (even from 2048 x ... resolution that i took from my digital camera).
2. and it gets worse after i burn them to VCD, does NERO have something to do with it? is there any special settings there?
3. What's the recommended compressor? FYI i use an 2,6 AthlonXP processor with 64mb Geforce4 Ti and 768Mb DDR, but my AMD Duron 750-32Mb Geforce2MX-128Mb DDR friend can have a better results than me. thx a bunch!

Hope these will answer your questions; Actually this is asked about every other week so searching through the archives here can probably yield some answers:

1. If you're using any other pic format than BMP or PNG , you are using a compressed file format. JPG and GIF are compressed formats for images, that way they are smaller to handle. And when you import these images into Premiere, whatever you are using as your codec and your compressions settings, you will again lost more quality

If you dont want to lose ANY quality at all, you must export as UNCOMPRESSED AVI. But at 10megs per second with sound, you will get VERY large file sizes.

Which is why codecs were invented.
Depending on your project type and what you plan on using the resulting stream for, will affect what kind of codec and quality you will want.

I highly suggest you put down some money and get DIVX (

) because it can take any AVI and compress it further without much quality loss. ITs the equivalent of what MP3 is to WAV or AU files.

If not, then you can use Microsoft's DV codec ( if you have Movie Maker on yoru system, its automatically installed )

2. VCD = worst than VHS quality. the resolution for VCD are 352x240 . And it uses MPG1 encoding. DVD's are Variable BIt Rate MPG2 and SVCD is Constant Bitrate MPEG2.

AGain depending on what you are doing, and what you plan on using it for, depends on the quaity of your end product. If you want to do VCD's you are going to have to live with it being worst than VHS quality.

If you want to retain quality as best as possible, then MPG2 SVCD's or DVD MPEG2 is your best choice; again they will be huge files.
