That is good to know but I am terminal challenged. Care to give a little bit more detail or a link to more info on doing this? thanks
Ok, first you need to install FFmpeg. It's an open source project, so the 'official' way is to download source code and build it yourself. Because it requires Xcode and lots of patience, the easier way is to get a precompiled binary. This site seems to have one:
http://ffmpegmac.net/
You can put it anywhere you want, but the common preferred location is /usr/local/bin. Open Terminal and execute (sudo will prompt you for admin password):
Code:
sudo mkdir /usr/local
sudo mkdir /usr/local/bin
sudo mv [B]~/Downloads/ffmpeg[/B] /usr/local/bin/
sudo chown root:wheel /usr/local/bin/ffmpeg
sudo chmod 755 /usr/local/bin/ffmpeg
Replace ~/Downloads/ffmpeg with the location you downloaded it to (you can simply drag the file into Terminal window).
Now you can run ffmpeg from any directory.
Let's assume you have a sequence of images in a folder named "images" on your desktop. The files are named img-0001.jpg, img-0002.jpg and so on. To make a movie "movie.mov" from these images you would type the following commands:
Code:
cd ~/Desktop/images
ffmpeg -r 30 -i img-%04d.jpg -vcodec copy movie.mov
-r 30 means rate of 30 frames per second
-i img-%04d.jpg is the input, %04d is a pattern meaning a 4-digit number with leading zeroes
-vcodec copy instructs ffmpeg to simply copy the source frames without re-encoding, creating MJPEG file. If you want something else, e.g. H.264, you need to specify x264 instead (there are lots of guides about H.264 encoding with ffmpeg).
movie.mov is the output file (you can also other extensions like .avi if you need another container format)
For more information about working with image sequences, see
http://ffmpeg.org/faq.html#SEC14 and
http://en.wikibooks.org/wiki/FFMPEG_An_Intermediate_Guide/image_sequence.
Other common use cases for ffmpeg are: extracting audio tracks from videos (MP3 from FLV or AAC from MP4), changing container format without re-encoding (e.g. MKV to MP4), resizing and cropping video, converting between various formats, creating thumbnails, etc. It's a very powerful tool.
