Formats for uploading content
The Layers of London project recommends using the Heritage Lottery Fund: Using digital technology in heritage projects-Good practice guidance.
For uploading new content to records, it is recommended that:
- still images should have a horizontal resolution of 1024 pixels;
- audio should be in WAV format, 44.1kHz, 16-bit; and
- moving images should be MPEG-4 compression at a target bitrate of 56Mbit/s, progressive,
720 pixels horizontal resolution, 4:2:2 chroma subsampling, with audio as above.
Providing only lower resolution material free of charge provides less public benefit and it is
good practice in all cases to create a high resolution master.
