Community Wishlist Survey 2021/Multimedia and Commons/Increase file size limit

Increase file size limit

  • Problem: Currently file sizes are limited to 4 GB. That is a problem especially for high resolution and/or just long videos.
  • Who would benefit: Users who want to upload and use high resolution and/or long videos or other huge files.
  • Proposed solution:
  • More comments: Limitations to prevent abuse could be realized by limiting to user rights.(like it is currently for mp3 files) This would be a community discussion with the input of the tech team.
  • Phabricator tickets: task T191802

  • We can't even upload files this size reliably anyway, especially PDFs and DJVUs. MER-C (talk) 20:28, 16 November 2020 (UTC)Reply[reply]
  • While I want this too.. this is very unlikely to be picked up by that team, because it is a very complex, cross departmental and expensive problem. In my personal opinion, supporting this would require a significant investment of a dozen or so of engineers with specific domain knowledge, to bring this to 'the next' level. Such an engineering effort would also require continuous sustained development by a team of at least 8 people (eternally forward). (Remember something like Vimeo, is a company with 600 employees and this is the only thing they do). —TheDJ (talkcontribs) 21:29, 16 November 2020 (UTC)Reply[reply]
    There are non-video uses for this proposal of course. --Izno (talk) 22:04, 16 November 2020 (UTC)Reply[reply]
  • I thought its possible under special circumstances, isn't it? Juandev (talk) 20:12, 17 November 2020 (UTC)Reply[reply]
    There's a hard cap of 4gb. This limit is technical in nature, the software wouldn't be able to handle anything larger even if we tried. -FASTILY 04:57, 18 November 2020 (UTC)Reply[reply]
    Google and other media websites make it work. "The cap is technical" is not really a nuanced view of what 4GB actually represents. --Izno (talk) 05:07, 18 November 2020 (UTC)Reply[reply]
    To be clear, I'm not advocating for the 4gb limit. There does seem to be a technical reason however: phab:T191805 -FASTILY 03:46, 21 November 2020 (UTC)Reply[reply]
  • Without specifying the maximum amount of size, this proposal should be archived before the submission phase ends. The WMF's servers wouldn't hold much amount of very larger files as of date AFAIK. George Ho (talk) 08:51, 19 November 2020 (UTC)Reply[reply]
  • I must say this is a safe mechanism: It will be technically possible to break the whole server (and website) through uploading bery large (e.g. 10+TB). Even if there is a hard cap, I suggest this cap not to be used, or at least, limit the right to those who genuinely need it.--1233 T / C 18:12, 19 November 2020 (UTC)Reply[reply]
  • I support increasing the cap like 50GB to allow higher quality or long play videos to be added in commons. Recent historical events are recorded in high definition and even 4K resolution videos. We are now in 2020s and no longer in the dial up era. -- Exec8 (talk) 14:21, 27 November 2020 (UTC)Reply[reply]

  •   Support in spirit, after issues discussed above are worked out. I do like the idea of having a user right like "LargeFileUploader", to stop people from doing asinine things like uploading Blu-ray rips and other copyvios, or just hitting Commons with a form of DoS attack sending enormous files of garbage.  — SMcCandlish ¢ >ʌⱷ҅ʌ<  07:39, 15 December 2020 (UTC)Reply[reply]
