Video Encoding

Encoding in H.265

I've seen very good quality and significantly smaller file sizes in videos encoded with H.265.

ffmpeg -i infile.mp4 -c:v libx265 outfile.mp4

Deinterlacing

ffmpeg -i 000000.MTS -vf yadif -c:v libx265 outfile.mp4

Timelapse From Image Files

In the terminal, go into your folder full of images.

neuro@gamma:~/timelapse$ ls

Create a timelapse of all files, with a framerate of 20fps:

ffmpeg -r 20 -f image2 -pattern_type glob -i "*.JPG" -c:v libx265 ../out.mp4

Create a timelapse starting from file 05200, with a total of 30 frames:

ffmpeg -r 20 -f image2 -start_number 05200 -i DSC%05d.JPG -frames:v 30 -c:v libx265 ../out.mp4

Note: the "%05d" means zero-padded 5-digit number.

I decided this section would be cleaner if I put it on its own page: AV1 Codec Testing
