Useing Scanned pictures in Edius?

[Ingwe]

Hope some body can give me advise, I am currently busy with a production, the company has given me certificates to use in the production , I did scan them high res (48bit tiff 600dpi) , then reduced the pictures down to 150dpi 720 x576 8bit rgb in PS and saved it as a psd, to use in Edius 4.5. but I get a very poor end result when it is used in Edius on SD as a end product.Should I use tag file or tiff and what rez ?

Thanks

never change the dpi after scanning

simply change the dimension to 768x576 for 4:3 (do not use 720x576)

apply 90deg x 1pix motion blur

check levels, around 16 for blackest and 235 for brightest

use tga 24bit

or leave image at full res and do a slow move over it with IM2

Thanks for this tip, Anton.

I am into scanning this weekend, so I am happy to know this already.

The above scanning settings are illegal for SD NTSC or PAL. Remember that there's a pixel aspect ratio difference that must be taken into consideration: 0.9:1 vs 1:1. Assuming you're scanning for PAL, then you should crop/scale your photo in Photoshop at 768 x 576, then import it in Edius. (There's another school of taught advocating the size of 788 x 576 for PAL, also taking into account the Digital Blanking Space of 18 pixels).

Anton Strauss suggestion above is an excellent one, particularly the white and black levels.

In short, I use the following table to scale from/to TV/Photoshop: (sRGB color space and scanning at 300spi)

601 NTSC 4:3 720 x 486 <-> 720 x 540
DV NTSC 4:3 720 x 480 <-> 720 x 534
601 NTSC 16:9 anamorphic 720 x 486 <-> 960 x 533
DV NTSC 16:9 anamorphic 720 x 480 <-> 960 x 540
601/DV PAL 720 x 576 <-> 768 x 576
601/DV PAL Anamorphic 720 x 576 <-> 1024 x 576
720i/p high definition 1280 x 720 <-> N/A
1080i/p high definition 1920 x 1080 <-> N/A

Other tables, advocating slightly different numbers here (depending how much of a purist you want to be)

To avoid color artifacts, for NTSC work, I then apply a filter to compress the out-of-gamut saturated blue&red colors:
Filter > Video > NTSC Colors

If you're involved in a production company and do a lot of scanning for video, I highly recommend using ScanGuide Pro. These scanning tables will tell you at what resolution, dpi, etc to scan (and much more than you ever cared or wanted to know) in order to achieve optimal results for your video stills.

Thanks Dimitri - good addition.

If you have a later version of Photoshop, it already has presets for you so no need to use correct aspect ratio files, it does it for you with a "preview" mode.

I usually scan pictures, color correct them, and leave them in the original resolution...I then load it up into After Effects and do photo stuff there. I try to scan the files at 300dpi so the computer doesn't have to work as hard to render it out or give me errors (Which is usual for AE and large images).

Thanks to all , this has help me a stack.
