I filmed a presentation where most of the content was slides scanned from old books and catalogs. To improve viewability I took the presenter's powerpoints, wrote them to .pdf and then individually scaled them in Photoshop. I then went into to each slide and saved the individual images as separate images (he had them all in .jpeg so I am stuck with that). It didn't look bad inside premiere but once I export it to an .mp4 the old images with lots of lines tend to crawl and its quite distracting. You did a little test video on the first slide:
Anyone know the best way to stop this before I jump into editing. I don't have access to the original documents--just the scans that were embedded in the slides. Also since there are 80 slides I am hoping the suggestion won't be something like "rescale all 80+ slides."
Thanks for any suggestions.
I suspect you may have resampled the images using Photoshop's default "Bicubic Automatic", which applies what some would say is an egregious amount of sharpening during downsampling.
I suggest changing the default resampling to just plain "Bicubic" and trying again. Bicubic resampling is better about not making artifacts.
No actually I used "Bicubic Sharpener" which is marked "Best for Reduction" since I was scaling the .pdf slide images down to frame size (670 pixel width)
But I care less about the slide images and more about the pictures that are on the slides which I imported directly from the scanned .jpgs. No retouching. I do a scale in Premiere to fit the frame width and then a pan up and down to show the detail. The image flashes in the video. Worse when the thing is static than when it is panning.
Maybe you could get more useful advice on the Premiere forum regarding prepping images for best video presentation. Not having done video myself, I'm just making educated guesses as to what might be the issue.
