Examples...


Simply convert the existing video from MOV to MP4.
ffmpeg.exe -i IMG_0551.MOV -c:a copy copy.mp4

Convert from MOV to MP4 and also scale it to 1280x720 (don't know what the original resolution was, but you get the idea; replace with 480 if you want even smaller).
ffmpeg.exe -i IMG_0551.MOV -c:a copy -vf scale=-1:720 copy.mp4

If original resolution is slightly non-standard and not evenly divisible by 2 and you're getting errors with the above command, this one gets around odd resolutions.
ffmpeg.exe -i IMG_0551.MOV -c:a copy -vf "scale=1280:trunc(ow/a/2)*2" copy.mp4


Cheers.

ffmpeg 
Sorry, no examples off the top of my head, but ffmpeg is the answer.

What is the best (quickest and most efficient) way to shrink the size of a video?

Someone sent a 11-second ".MOV" video that was 25-megabyte. I first tried to use mencoder to convert it, but it did not work. So I used

https://cloudconvert.com/mov-to-mp4

to convert it from .mov to .mp4 and that cut the size to about half.

Then I used www.videosmaller.com/ to convert it to a smaller mp4.

Surely there must be a quicker, more efficient, single-step way to get the best possible result that still has "reasonably" good quality video.

-rw-r--r--13196515 Jul  9 20:04 buffb4.mp4
-rw-r--r-- 7594494 Jul  9 20:07 buff.mp4

I uploaded the current 7.5-meg result here:
