When you take a photo when playing back a tape, the jpeg image size is much smaller.

Under the right conditions, these cameras can take great photos.

Hmmm.... The manual did not give me that impression... I'll have to experiment. It looked like the jpegs would be just as big as long as the tape was made in HD and the photo to card settings were for LW and the image quality set to "super fine" (page 110)

Chris. It would be an honor, with all the useful info I've gotten on your site.
I would actually write in more if it were not for the wealth of info already available here.

Happy New Year & Thanks

In general terms, photo's taken live are over 1 megabyte jpg files.

Photo's taken from tape are generally under 1/2 megabyte in size.

Some examples:

Live:

1,101 KB
1,566 KB
1,217 KB

Photo Taken from HDV Tape:

483KB
480KB
484KB

As you can see, each file has a different size due to the jpg compression.

I see what you mean now, - not resolution but size.
Do you happen to have any comparisons you could post?

For my purposes, I often I don't notice the difference between reasonably well done jpeg compressions and the originals. Are the pictures taken directly from camera to card not compressed at all? I'm just wondering how noticable the size difference is.
