Upload and manage video creatives

Upload a video or add a VAST tag, send it for review, and learn which formats and sizes are accepted and what each status means.

A creative is the ad itself: a video you upload, or a VAST tag that returns one. LtvAdx reviews every creative before it can play.

Before you start

  • Verify your email. Uploads from an unverified address are refused.
  • Export your video as MP4 (H.264) or MOV, no longer than 120 seconds and no bigger than 300 MB.
  • Your account needs to be approved to submit a creative for review. Until then you can upload and keep drafts, with a daily upload limit and one video processing at a time.

Steps

  1. Open Video Creatives and select Upload Creative.
  2. Enter a Creative Name and choose the Ad Format and Duration (seconds). Enter the real length: it decides which ad breaks the creative can fill.
  3. On the Video file tab, choose your file. Or paste a hosted MP4 link. Or open the VAST URL / Tag tab and enter an https VAST tag URL or inline VAST XML.
  4. Add a Click-through URL, and set skippable or a companion banner if you use them.
  5. Select Save draft. A video starts converting.
  6. When the video column reads Ready, select Submit on the creative's row.

What happens to an uploaded video

LtvAdx converts it for TV screens: sizes from 1080p down to 360p as MP4 and as streaming versions, with the sound levelled to -24 LKFS. This takes a few minutes. The list refreshes while it runs.

Video columnMeaning
ProcessingBeing converted. You cannot submit it yet.
ReadyConverted and checked.
HeldConverted, but kept off the public media host until your account is approved. It plays nowhere yet.
FailedThe reason is shown when you open the creative.

A hosted MP4 link is not converted. It is checked before approval: it must return video over https. A VAST tag is third-party, so only its presence is checked, and it is read when the ad plays.

Review

  • Draft: saved, not sent.
  • Pending review: LtvAdx is checking it.
  • Approved: it can play. You get an alert.
  • Rejected: the notes on the row say why. Fix it and select Submit again.

If you replace the video, or change the link, click-through or companion of an approved creative, it goes back to draft and stops playing until it is approved again.

Which creative plays

You do not attach creatives to line items. Any approved creative on your account can play on any of your line items, as long as it fits the ad break. When several fit, the longest one that fits plays. A bumper break takes only creatives with the Bumper 6 format. To stop a creative playing, delete it.

If something goes wrong

  • This file is not an MP4 or MOV video we can read. Export it as MP4 (H.264) and upload it again. Playlists, WebM and other formats can't be uploaded.
  • The file is larger than 300 MB, or The video is N seconds long; the limit is 120. Compress or trim it.
  • Your last video is still being processed. Wait for it to finish before the next upload.
  • You have reached today's upload limit for accounts awaiting approval. The limit lifts once your account is approved.
  • Upload a video or give a video URL first. Add the media before you submit.
  • The video is still being processed. Submit when it reads Ready.
  • A creative is approved but the line item does not play it: check its length against the break, and see Why a campaign is not delivering.

Political and issue ads need a declaration on the creative. See Political and issue ads.
