Knowledge wishes to encourage the use of innovative production techniques, however the results must be delivered within accepted industry standards to allow for error-free presentation and transmission.
- Program material must be produced using professional broadcast equipment and acquisition formats. Facilities used for production and post-production must have viewing and sound monitoring conditions that comply with industry standards.
- Program shall be free of commercial blacks or publicity breaks.
- Program must be in English with name supers and titles.
- The lower left hand corner of the screen must be free of captions, logos, watermarks or any graphic images.
- Unless otherwise permitted in writing, duration shall be a maximum of 26:30 for a half hour program; a maximum of 56:30 for a 1 hour program, with no commercial or publicity breaks. There are no duration restrictions for programs with run times greater than 60 minutes.
- Both the broadcast master and its container shall be labeled clearly and legibly. The container shall display the following information:
- Version (master, protection, dub, clone, etc).
- Production company.
- Program title.
- Program length.
- Type of audio, channel assignments, Dolby if applicable.
- Type of time code.
- Presence of closed captioning.
- Descriptive video audio track (if relevant).
- Day, month and year of delivery.
- The picture must be sharp and well lit, unless artistic considerations require otherwise.
- The video signal must be free of excessive black crushing and luminance clipping.
- Colour rendition - especially skin tones - must be a realistic representation of the scene portrayed unless artistic considerations require otherwise.
- Video processing (e.g. effects plug-ins) must not introduce unintentional changes to luminance and chrominance levels.
- There must be no visible contouring or artifacts caused by multiple D-A and A-D conversions or compression. Quantization noise shall not be apparent.
- The audio shall be free of extraneous signals such as noise, hum, and cross-talk.
- Sibilance and distortion shall not be apparent.
- The audio shall not show dynamic and frequency response artifacts as a result of the use of noise reduction or low bit rate coding systems.
- Dynamic range shall not be excessive.
- Care shall be taken when incorporating background music and effects with dialogue, otherwise viewers with a hearing impairment and/or poor listening conditions can find the dialogue difficult to hear. Final mix assessment should be made using "TV Set Style" speakers.
- Sound loudness levels should be consistent throughout the program such that it is not necessary for the viewer to adjust the sound during the program or between parts.
- The relative timing of the sound to video synchronization should not exhibit any perceptible error. Sound should not lead or lag the picture content.
- Producers must maintain music and effects levels sufficiently below dialog to ensure that a wide variety of viewers can understand the dialog upon first viewing in home conditions.
1. Delivery Format
- 1.1 Video tape: HDCAM (1080i/29.97) with separate .scc closed captioning file. HDCAM SR will not be accepted. Labels, reference signals, time code and audio specifications are the same as for file delivery.
- 1.2 File:
Windows PC formatted as NTFS or
|Field Dominance||Upper field first|
|Closed Captions||Separate EIA-608/708B .scc file delivered on the same hard drive, “pop-on” style, with Drop Frame time code to match video file|
|NLE Export Formats||
ProRes 4:2:2, @ 147 mb/s or
|Image Format||1080i (Interlaced) 1920 x 1080|
|Field Rate||59.94 (Frame rate of 29.97)|
|Time Code||Drop Frame|
|Luminance (Y)||Waveform (0-100 IRE)|
|Chroma (UV)||Waveform (0-105 IRE)|
|Audio Phasing||In phase, stereo audio must be fully mono capable|
|Audio Bit Depth||24 bits|
|Sample Rate||48 Khz|
CH 1. left and CH 2. right full mix stereo
|Audio Stems||Delivered as separate files, audio stems will include at a minimum; stereo music and effects tracks and a dialogue track|
Program audio peaks no more than minus 10 dBFS
Minus 24 LKFS (+/- 2dBFS) as per BS.1770-3 Dialog
|Bars and Tone||
Smpte 75% or 100% bars and tone at 1kHz @ minus 20dBFS
|If a program has values outside of these limits, most notably maximum values of luminance (brightness), chroma (colour), and peak audio levels, video and/or audio distortion will result. Ensure colour correction filters have been applied to video, nested sequences, and graphics, and perform a peak audio sweep prior to project export.|
2. Image Format
- 2.1: The image format shall be 1920x1080 (1080i) and be compliant with the SMPTE 274M-2008M standard.
3. Frame Rate
- 3.1: The video frame rate shall be 29.97 fps, 2:1 interlaced. Any content captured at another frame rate such as 24p or 23.98p shall be converted to 29.97 with Drop Frame time code before being delivered to Knowledge.
4. Use of Standard Definition Material
- 4.1: Use of native standard definition content, including PAL, NTSC, SECAM or R.601 digital video is acceptable only in special cases, i.e., archival material. Any use of SD content in an HD program must be approved beforehand by Knowledge.
- 4.2: When the use of 4:3 SD content is essential and has been approved by Knowledge, two methods of up-conversion are acceptable: pillar-box and top-bottom crop. Conversion by horizontal stretching is not acceptable.
- 4.3: When the use of 16:9 SD material is essential and has been approved by Knowledge, the use of 16:9 full height anamorphic is preferable over letterbox.
5. Consumer formats
- 5.1: Use of material captured with consumer formats within HD programs is not accepted unless it is a result of special requirements such as shooting in a confined location. Any use of any consumer format in an HD program must be approved beforehand by Knowledge and shall be accepted only when there are no other options.
6. Reference Signals
- 6.1: Reference colour bars and 1 KHz audio tone is required at the head of each program. Reference audio and video signals must be a true indication of the program’s chroma, video, pedestal, audio phase and audio level. There should be a minimum of 30 seconds of black following the last program picture and audio before any text less elements or added material.
7. Video Slates
- 7.1: Slates must have a duration of at least 10 seconds, follow reference signals, and include the following:
- Series and episode title and number.
- Total program length including frames.
- Audio track assignments.
- Type of time code.

8. Time Code
- 8.1: SMPTE time code must be drop frame, start with reference signals and continue unbroken throughout the entire program and past the end of the program by a minimum of 15 seconds. The following standard must be adhered to:
|09:58:40:00||Black and no audio|
|09:58:50:00||Colour bars and tone start|
|09:59:55:00||Black and no audio|

|Channel 3||M&E Left|
|Channel 4||M&E Right|
- 9.3: Normal audio channel/track assignments: For FILE delivery
|Channel 1||Left Stereo total|
|Channel 2||Right Stereo total|
|In addition, delivered as separate files, Audio Stems, stems at a minimum must contain stereo music and effects tracks, plus a dialogue track.|
10. Closed Captioning
- 10.1: Closed captions shall be delivered as a separate .scc file on the same hard drive as the program file. Pop-on caption mode is preferred, however, roll-up may be deemed acceptable. The .scc file must include drop frame time code that matches exactly the drop frame time code of the video file.
The purpose of the downloadable Producer’s Technical Evaluation Form is to provide information to Knowledge staff and it also serves as a check by the producer ensuring the program meets technical specifications as outlined in this document:
- A completed copy of this form must be included with the delivery of the program master file.
- The technical check must be completed by a qualified technician using industry standard equipment and measuring devices
- Cue sheets must accompany the broadcast master
