problem with still photographs within a movie

Hi all,

just exported a sequence to QT7 256kbs mov yesterday. it included a series of stills, quite large jpegs taken directly from a panasonic lumix Tz5 cam ( about 5 meg each), that had some panning and zooming movements. The first thing I noticed was that the photos were very soft, unlike viewing the originals in a simple picture browser. I also found the pans and zooms to be not smooth at all.
Is this due to the QT format or another issue altogether?
Thanks!

It's due to the low bitrate you chose.
Try Sony AVC using the Internet 4:3 SD 30p preset.
Your file size will be smaller and I think you'll be much happier with the results.

Thanks a lot Mike.
The rendering options and formats are something I really need to get my head around, it all seems a bit confusing to me at this point. i thought the QT7 256kbs format was something quite standard and net friendly, until I saw that my 5 or so minute mov was 260 meg large...
is there a guideline somewhere that helps understanding and choosing the rendering formats? the manual is not very specific at all about it.

If it ended up at 260MB then the bitrate must have been 256KBps not 256Kbps (Bytes vs. bits).

In any case, rendering to a smaller video frame (320x240 or even 640x480, for example) is going to reduce your pictures to a tiny fraction of their original resolution. They're going to look softer with less details no matter what render settings you choose.

Dont forget also to select the highest quality rendering settings for smoother pans and zoom.
