Video of Still Images

Hi,

I am trying to make a Youtube video comprised almost entirely of still photos; the pictures were prepared in Photoshop and measure 1920 x 1080.

Initially, I saved the pics at 300dpi but later reduced them to 72dpi. The images weigh approximately 1.5 MB – 1.8 MB each, but with just three added to the clip, the file size reaches 28 MB when the “YouTube 1080p Full HD” preset is selected and 18 MB when “Match Source – High Bitrate” is chosen. In both cases, deselecting Export Audio helps a bit, but not much. Selecting “Use Maximum Render Quality” and “Render and Maximum Depth” doesn’t appear to affect file size.

I hope to include 50-100 pics in the clip, but at this rate, the file size will easily exceed the established limit. I don’t see how three pics weighing just 4.5 MB can translate into such a huge file. I tried adding nine images and the file size exploded to 55-85 MB.

Am I doing something wrong? What is the correct/best dpi setting for still images?

Thanks for any help you can provide.

Kind regards,

Mark
