avifenc -l four-colors.png -o four-colors.avif Generated using MSPaint like a true professional. You can tell if you need to by whether or not tests pass.

If you use ffprobe -show_packets to get sample offsets, you may need to add 4 to each pos value.

Add 8 to offset and subtract 8 from the size to get the values the tests want.

avc1.avcC has an offset, size in the same view.

Description entries can be found under .stbl.stsd in box view.

Use a multi-line edit mode and clang-format to quickly format entries.

Sample offsets can be copied from the “Sample View” tab after unchecking all but offset and size.

When updating the sample offsets and descriptions for tests using mp4 files, it's easiest to use mp4box.js.
