 +==== Videogröße reduzieren: H.264 ===
 +
 +The CRF parameter sets quality and influences file size. Lower values mean higher quality.Typical values range from 18 to 28 [[https://trac.ffmpeg.org/wiki/Encode/H.264|(default is 23)]].

 +
 +Resize to 1080: ''-vf scale=1920:1080'', tune for slideshow: ''-tune stillimage'' (it seems only one -vf filter can be applied).\\
 +''-t 300'' encodes 5 minutes for quick quality control:
 +
 +<code bash>
 +ffmpeg -i input.mov -t 300 -vf scale=1920:1080 -crf 26 -tune stillimage -c:a aac -movflags +faststart output1080.mp4
