tiff vs jpeg in Premiere Pro

[louisk15879142]

I have a set of 50 year old slides I want to scan and use for b-roll in Premiere.  I'm importing HD video and working in HD during editing.  This allows me to get good quality when I use the Ken Burns effect.  I want to be able to do the same on the stills I import.

Some professionals I ask insist on using tiffs for this.  Others say jpegs are fine. 

Secondly as I understand it now my HD gives me a total of 2 Megapixels.  Therefor I should scan my slides so that I get the approximate same number of pixels.

Feed back appreciated.  At this point I'm exporting at H-264 for uploading to the Internet.  I have no plans on any "big screen" showing of this work.

I  use jpegs as tiffs are for printing. Scan them and edit them in Photoshop for the sizes and quality. You can do them as individual layers as jpegs  or psd in a Photoshop composition with layers in a 1920 x 1080 frame master psd file. I use the psd as I can go back to fix the pictures while in Premiere until finishing.

My two cents:

Scan the images as high quality master tiffs. Take the scanned image files into Photoshop and create files for use in Premiere as 72 dpi* .png files that are at least twice the pixel dimension of the sequence you want to edit them in. This will allow you to zoom in by scaling to 150% without degrading the image.

Example: if editing on a 1920x1080 time line, I would make the stills 3840x2160 .png files.

Since the aspect ratio of your slides will not likely be 16:9, you'll need to use your judgment as to either cropping the image in PS to a 16:9 aspect, or creating a larger .png (3840x3000 to preserver that slides original aspect ratio.

*All video is 72 dpi. Higher dpi is irrelevant working in video.
