Part of it confuses me a little:
"Because all online video formats utilise lossy compression, published
videos cannot be edited further to correct or update them, and they
cannot be re-used by others for different projects – unless one is
willing to accept a dramatic degradation of quality.
This is kind of confusing, as MP4 is usually used in
lossy mode (Just
like webm), so neither is exactly ideal for video editing.
The issue discussed is just that re-encoding deteriorates quality, no
matter what codec is being used.
Many cameras use MP4 codecs, so allowing MP4 uploads to Commons would
allow people to store the original footage there which other could use
for remixes or to re-render existing video projects (if project files
were also made available).
Actually the mentioning of MP4 and the Commons consensus is confusing
here because it is just a side issue - the underlying problem has
nothing to do with MP4, many cameras also use different (non MP4)
formats, hence the Commons decision is just a secondary issue.
