looking and cant find the perfect one.
i have 100 gig of 4K image-sequence to process.
found imagizer2 on sourceforge. multi-thread but not 64bit (does matter?).
i guess the fastest one will be using intel's IPP image core lib .
i am on windows, but if some crazy fast linux option is available i'll consider (benchmarks?).
included benchmarks i ran on a test batch of 100 5k (4.3MB) files
- image resizer for windows = 20sec
- batch picture resizer = 30sec
- imagizer2 = 64sec
- irfanView = 80sec
- Fast image sizer= 110 sec
- imageMagick-6.7.1-Q16x64 = 149sec
ffmpeg -i d:\g\25\g_%%04d.jpg -r 15 -s hd720 -vcodec libx264 -fpre "libx264-hq.ffpreset" -crf 16 Day01_720.mp4
but fmpeg is hard coded to support images no larger then 5012pixels. hence the resize.
