FFmpeg Batch .mov > .gif conversion
26 juin 2022, par Bumblefoot89I am trying to batch convert a folder of .mov's into .gif's.


Input .mov's are 1920x1080 resolution and I would like to convert to 720x480 (to save file size). I have the following code, but not sure how to add the -vf scale=720 into this code :


for i in *.mov; do ffmpeg -ss 1 -i "$i" "${i%.*}.gif"; done



The above code works, just running it through terminal. Any help on adding the scale or any other optimizations to reduce file size would be greatly appreciated.


Thanks

Using ffmpeg to convert an SEC file
29 septembre 2023, par annaI need to convert an SEC file into any video format that I can share and/or upload to Youtube. MP4, etc.



I'm a complete newbie at all things terminal. I've tried :



ffmpeg -i video.sec video.mp4



ffmpeg -i video.sec -bsf:v h264_mp4toannexb -c:v copy video.avi



ffmpeg -i video.sec -b 256k -vcodec h264 -acodec aac video.mp4



I don't understand what any of these mean, they're just examples I found online. However, whatever I try returns this error :



Invalid data found when processing input



Any thoughts ? Thanks !
