Checking a file quickly
Verifying without taking the file into the library.
The quick check sits under „Prüfen“ (Verify), the first entry in the sidebar; the wordmark at the top left leads there too. One file, one result, no entry in the library, which the sidebar calls „Library“ — the route for somebody else’s file that needs an answer right now.
Anyone signed in and a member of a workspace — headed „Tenant“ in the user menu — may verify. No particular role is needed.
The signed-in product is in German, so its wording is quoted in German here, with the English rendering in italics.
How it is used
Drag the file onto the area headed „Datei hierher ziehen“ (Drag the file here), or pick it from the file dialog with „Datei auswählen“ (Choose file). Above it on the right, the button „Was wird hier geprüft?“ (What is checked here?) opens a short explanation.
A card with the file then takes the drop area’s place. Its bar runs from the drop on, and the line below says what is happening: „Wird vorbereitet …“ (Preparing), „Wird hochgeladen …“ (Uploading) with the percentage and the MB transferred, for larger files after a few seconds also the time left, and finally „Wird geprüft …“ (Checking). Once the check is through, the card becomes a narrow row, „Weitere Datei hierher ziehen“ (Drag another file here), for the next file, and the result sits right below it.
Drop a second file on the card while a check is running, or pick one with „Andere Datei wählen“ (Choose another file), and the later one wins. The first result then never arrives.
What happens to your file
The file is uploaded. It is not checked in the browser. For the check a copy goes into storage in the EU and is evaluated automatically there — no member of staff looks at it. That copy is deleted at the latest twelve hours after the upload. The subtitle of the drop area says as much: „wird nur temporär zur Prüfung gespeichert“ (stored only temporarily, for the check).
The file itself is not altered by the check.
The file does not land in the library unless you explicitly choose that. The result is on the page and gone once the page is closed. To keep it, use „In Library speichern“ (Save to library) below the result. Only then is an asset created, and only then is the result recorded for good. Where the file is already in your library, the button is not there.
When saving you choose where the asset goes: a project and a folder within it. The default project and „Unsortiert“ (Unfiled) are preselected.
Formats and size
More formats can be verified than can be uploaded into the library: PNG, JPEG, WebP, TIFF, AVIF, HEIC, GIF, MP4 and MOV. WebP, TIFF, AVIF, HEIC and GIF are refused by the library upload and accepted by the quick check. They still get in through „In Library speichern“, and once there they are verify-only assets with no editor.
On this route the ceiling is 100 MB for every kind of file — video included. A larger video of up to 1 GB can be uploaded into the library if it runs up to 3 minutes, is at most 4K (3840 × 2160) and is not ProRes; it is verified there as well.
„In deiner Library“ (In your library)
If the file’s checksum matches an asset or a signed export in your own workspace, the section „Content Credentials“ opens with a line naming the match, with the link „Öffnen“ (Open): for an original its file name, for an export „Ausgabe von …“ (Output of …) with the format.
The comparison runs across your whole workspace, over all projects you have access to. Somebody else’s file never produces a match; assets in the trash and in deleted projects do not count. No match says nothing about the file — only that it did not come from your library.
What can go wrong
„Dateityp … wird nicht unterstützt“ (File type … is not supported). The message lists the acceptable formats. For HEIC files Chrome frequently reports no file type at all; the extension then decides, and an unknown extension means refusal.
„Datei ist größer als 100 MB.“ (File is larger than 100 MB.) On this route 100 MB is the ceiling for every kind of file. The message comes as the file is picked, before anything is uploaded. For a video of up to 1 GB it goes on: „Bitte das Video über die Library hochladen — dort wird es ebenfalls geprüft. Die Library nimmt Videos bis 3 Minuten und 4K (3840 × 2160) an, ProRes nicht.“ (Please upload the video through the library — it is verified there as well. The library takes videos of up to 3 minutes and 4K (3840 × 2160), not ProRes.)
„Der Inhalt der Datei passt nicht zu ihrem Dateityp. Bitte die Datei im
richtigen Format speichern und erneut hochladen.“ (The file’s content does
not match its file type. Please save the file in the right format and upload it
again.) The message comes after the upload, before the check starts. The
content is a different format from the one the name states, and not one that is
accepted in its place — a video with the extension .png, say, or a HEIC photo
with the extension .jpg. A PNG with the extension .jpg, on the other hand, is
verified as PNG.
„Die Prüfung ist fehlgeschlagen.“ (The check failed.) The message says no more than that; it never names a technical reason.
„Zeitüberschreitung bei der Prüfung.“ (The check timed out.) After about five minutes the page stops waiting.
„Die Prüfung konnte nicht abgeschlossen werden. Bitte erneut versuchen.“ (The check could not be completed. Please try again.) The run was interrupted — the network went, for instance.
Saving to the library is refused although the check had finished. This has one of four causes. The chosen project or folder has been deleted in the meantime; then choose another destination and save again. Or the temporary copy has since been deleted; then it reads „Die hochgeladene Datei ist nicht mehr vorhanden. Bitte die Datei erneut prüfen.“ (The uploaded file is no longer there. Please check the file again.), and the way on is to check the file again and save after that. Or there were too many attempts in quick succession, in which case it reads „Zu viele Versuche in kurzer Zeit. Bitte einen Moment warten und es erneut versuchen.“ (Too many attempts in a short time. Please wait a moment and try again.) Or the temporary copy was replaced after the check by a file whose content does not match its file type — saving looks at the copy once more. Then it reads „Der Inhalt der Datei passt nicht zu ihrem Dateityp. Bitte die Datei im richtigen Format speichern und erneut hochladen.“ (The file’s content does not match its file type. Please save the file in the right format and upload it again.), and the way on is the same as in the second case.
A card with figures appears instead of a note. Saving to the library takes up storage and is checked like an ordinary upload. If the workspace allowance is exhausted, the card names the used and the permitted figure — and the fact that the trash still occupies storage.
