Hi,

I'm totally new at this video editing. I'm about 3 years experienced in photography but not this HD thingy, so excuse my dumb questions. As for image editing, I prefer to shoot RAW and edit in RAW editor and finally convert to high quality Jpeg for sharing or printing...

So I'm wondering if let say, I edited bunches of clip in X2 and render them into AVCHD. Will it be a compressed video that is lower in quality compared to my original clips?

Thanks

First I prefer to convert any RAW photos to Bitmap or TIFF if I'm going to print, JPEG, or PNG for sharing on the internet..

AVCHD is a highly compressed MPEG file, and MPEG is a lossy format. The loss in quality results in successive or generations of rendering. Your initial rendering will not have any noticeable degradation. However further generations will.

Example, you take your Source video from your camcorder, edit it and render it to Video A, no noticeable loss. Later you take Video A, edit it and render it which would be Video B, it will start showing some loss. Continue this pattern and you will end up with a poor quality video...

Thanks vidoman... that's the answer I'm looking for...

Is that mean AVI file is an uncompressed file?

Thanks

There is an uncompressed AVI that measures a whopping 65GB per hour. The more common DV-AVI is compressed, but is considered a relatively lossless format. It is about 13GB per hour.

65GB per hour?? wowww....
