how to export multiple pngs from preview mac os high sierra

I believe that's why it's almost impossible to see the quality on the fly, unless you use an uncompressed format, but then you don't need to preview anything. Most video codecs use algorithms, that are different from a still image, because most of them work temporally by calculating pixel values from one frame to another, or from one time point to another, and implementing the system of different levels of importance of frames. There shouldn't be guess work involved in either image options or animation, so I thought either there should be visible text or better yet, what Peter has suggested, and in that case a full size frame would give the most information IMO. true, and I haven't exported an image sequence in years, but would it be impossible to do the same for animation? I had to just take a guess which is most likely to be the best and have been lucky that my guess was a lucky one. To me this is very important! The export setting are often used at the end of a deadline where the pressure is highest and when settings like these are contradictory like this it can get us in awful trouble with clients to whom we often have to deliver these image sequences. Better to use the term 'Compression' instead,where the highest number is maximum compression and the lowest number has the least amount of compression.

Also the term 'Quality' is confusing in this context. This is unnecessarily confusing and counter-intuitive! The quality scale should be consistent for ALL image export settings. When selecting Jpeg export, the Quality Setting is completely reversed 1 is highest compression and 100 is least compressed. (Confusing because I would expect Quality 10 to have the maximum quality and thus least amount of compression.) When selecting PNG export, we can choose a Quality Setting from 1 to 10 where 1 is lowest compressed and 10 is highest compression. I just noticed that when exporting images through the Export Footage panel the quality setting are not consistent and confusing!
