Video File Specifications


Extreme Reach provides multiple solutions for uploading creative assets to your account. Whether you choose to upload spots via the Media Uploader Application or through ER, all files must meet the specifications in this document before they can be accepted.

To help ensure that your files are seen and heard exactly as you intend them to be, please review and follow the detailed specifications below.
Verifying the playout of your final digitized files locally prior to uploading to Extreme Reach is imperative.

File Naming

The file name should be the Ad-ID with the file extension at the end (e.g., ZYWX9876000H.mpg or If you’re not using Ad-ID, file names should follow these guidelines:

  • File names can only contain letters and/or numbers (special characters are not allowed).
  • HD file names must end with an “H” but cannot end with “HH” and the SD file name must match the HD file name with the exception of the “H” (e.g., ZYWX9876000).
    Note: In Canada, the “H” is not a requirement for HD assets.
  • To avoid any potential rejections from TV destinations, keep file names to 12 characters or fewer for HD, and 11 for SD. See below for specific restrictions.

TV File Name Restrictions

max. 12 characters for SD or HD
max. 12 characters for SD
max. 13 characters for HD
max. 15 characters for SD and HD
max. 15 characters for SD and HD
max. 18 characters for SD and HD
AT&T AdWorks
max. 20 characters for SD and HD
max. 25 characters for SD and HD

Content Layout

All TV assets must adhere to this configuration before uploading to ER.

5 seconds of Slate
Ad-ID must be present on the slate and must match the Ad-ID in the metadata. If you use “/H” then the same slate can be used for HD and SD. See sidebar for sample slate layout.

Slate should include the following:


No Audio on Slate
There should be no audio in the slate, however, a 2-pop at the end of the slate is acceptable as long as it does not exceed -20 dBFS.

Start frame
Active audio/video must start on frame 210 for 29.97 fps or frame 168 for 23.976 fps. First frame is counted as frame 0. Video content must run to the last frame with no additional black (see sample below for a 30-second

Standards and Practices

Audio Levels
ATSC RP A/85 and ITU-R BS. 1770-3

Target Loudness level should be -24 LKFS
Minor measurement variations up to approximately ±2 dB from this value are anticipated due to measurement uncertainty, and are acceptable. The target loudness level should not intentionally be -22 LKFS or -26 LKFS. In order to provide consistent audio levels, any content that does not conform to the -24 LKFS loudness level will be normalized to meet the loudness requirement. This internal process will shift the average loudness to -24 LKFS with no impact to dynamic range.

True-Peak level should be below -2 dB TP
This provides headroom to avoid potential clipping due to downstream processing. To avoid any potential rejections from TV and digital destinations, we recommend keeping true-peak levels below -6 dB TP.

Video Levels
ITU-R BT.601, ITU-R BT.709, and EBU R 103

Waveform Monitor Scale Levels:
Black level = 0% / 0mV
White level = 100% / 700mV
RGB = 0% - 100% / 0mV - 700mV

Digital Levels Using 8-bit Coding:
0% = Digital value of 16
100% = Digital value of 235

Signals exceeding 5% of the above levels and 1% of the image for a 4-second duration are considered “Out-of-Gamut”.

Safe Title Area
SMPTE ST 2046-1
The safe title area is 90% of the width and 90% of the height of the production aperture. All graphics, text and frame composition elements should be placed within the safe title area to prevent key content from being cut-off.

All TV assets with graphics, text, and frame composition elements outside of 93% (Safe Action Area) will be rejected.


Center Cut Protection
SMPTE RP 2046-2
The center cut protected area is 90% of the width and 90% of the height of the 4:3 aperture. All graphics, text and frame composition elements should be placed within the center cut protected area to prevent key content from being cut-off when downconverted to SD.



Closed Captioning

  • CEA-608 is required (CEA-708 is optional). Assets without 708 will automatically derive 708 from 608.
  • Files must have a frame rate of 23.976 fps, 29.97 fps or 59.94 fps.
  • For MPEG files, CEA-608 data must be compliant and present (SMPTE 436M for MXF file types and QuickTime closed captioning track for MOV file types).
  • All assets intended for broadcast in Canada must contain closed captioning.
  • The first caption should be “paint-on” and occur on or after the fifth frame of content or there must be a one-second delay if the first caption is “pop-on”.



  • Must be readable, clear and conspicuous against a contrasting background and appropriately drop-shaded.
  • Must be 3 seconds for the first line plus 1 second for each additional line.
  • Font size should be at least 22px tall with letters, words and lines spaced so as to be easily read.
  • Horizontal crawls are not allowed.

Sign Languages

  • Should be title safe.
  • Should be displayed in the bottom-right corner.
  • Should not block graphics, text and frame composition elements.
  • Viewers need to be able to clearly see all movements and facial expressions.
  • Must be verified by an external, third-party source and the translation and verification must be provided in writing.

TV Ratings Bug

  • Competitive advertisers must use the TV Ratings bug if the show is rated.
  • ER does not QC for dimensions or duration.
  • Should be title safe.
  • Should be displayed for at least 5 seconds.
  • Should be 213x140.
  • Should have black letters on a white background or white letters on a black background.
  • It can be opaque or partially transparent, as long as it is clearly visible on the screen (a 70%opacity is acceptable).

QR Codes

  • Not all TV destinations accept QR codes.
  • Some TV destinations will test for QR code operability and compliance with their standards.
  • TV destinations cannot guarantee that the QR code will function correctly.
  • ER does not test for QR code operability, dimensions, or duration.
  • Should be title safe.
  • Should be displayed for at least 10 seconds.
  • Should be at least 240x240.
  • There should be enough contrast between the QR codes and the background.
