Still Frames: Leopard Grab with higher quality than FCP7!?

[johnwhite]

Why a freezed frame from FCP seems skecthier than with Grab?

Lookin' for the perfect frame grab i've come up to this "problem"..

Example
Video Format: DVCPro HD 1920x1080
Same video section (slow movement)

FCP: Modify: Make Freeze frames: Export using quick time conversion: Still Image: Best Depth
(on de-interlaced & interlaced video):an 8MB TIFF

Leopard Grab: Capture: Window
generates: a 2.7MB TIFF


Comparing these, with extreme zooming on video watermark text:
1. TIFF from Grab is much clearer
2. TIFF from Grab it also comes brighter than image from FCP

Any comments are apreciated. Obrigado

 

[johnwhite]

is this the answer?

Well,

forgot to mention images have the same number of pixels.

Well, a general answer to this question should be,
because FCP provides visualization with variable settings, while Grab is straight forward.

with this in mind I re-confirmed sequence settings (they were matching video), and used codec ProRes 4444

still, the frame isn't so good! .. Grab 1 - FCP7 0

I'm I on the right way?

Can you post the two still frames or link to them for comparative reasons?

Hmmm...

Also try this:

Position the playhead on the frame you want to capture as a still image and then choose File > Export > Using Quicktime Conversion and choose "Still Image" from the pulldown list in the dialog box that appears. It defaults to PNG so you'll have to click the Options button to change it to TIFF. This has always yielded pretty good still images for me.
