Video Encoding

To ensure optimal video playback on most smartphones, we recommend encoding in MP4 format with H.264 codec at 480p resolution. This format is sufficient for smooth and good quality playback on mobile devices.

Encoding with ffmpeg

To encode one or more videos with ffmpeg, use the following commands:

# Encoding a video where "video.mp4" is the original video and "video-min.mp4" is the compressed video
ffmpeg -i video.mp4 -s hd480 -c:v libx264 -crf 23 -c:a aac -strict -2 "video-min.mp4"

# Encoding all videos in a folder
for file in $(find . -name "*.mp4" | sort -z); do
    ffmpeg -i "${file}" -s hd480 -c:v libx264 -crf 23 -c:a aac -strict -2 "${file%.*}-min.mp4"
done

Encoding with Handbrake

If you prefer using a graphical software, we recommend HandBrake. To do this, follow these steps:

Open HandBrake and load your video file
Select the "HQ 480p30" preset
Make sure the output format is MP4 and the video codec is H.264.
Choose an output location and name for the video
Click "Start" to begin encoding.

These recommendations ensure maximum compatibility and optimal quality for playback on various devices.
