UWS on iTunes U: Quality Assurance Guide This guide has been developed to assist you with the creation of content for use on iTunes U. Audio Capture Ø Ensure best placement of microphone and recording device. If capturing interviews, try to keep external noises to a minimum for the clearest voice capture. Be aware of handling noises if holding or wearing the microphone during recording. Use headphones to monitor the audio recording where possible. Ø Audio should be set to record in the highest quality option available. Ø Digital audio recording levels, particularly voice, should peak between -­‐12db and -­‐6db. Audio recorded higher than this range may result in unacceptable distortion. Post Production Ø Ensure native quality is maintained. Ø Do not use any copyright music – all music must either be copyright-­‐free or have been released by both the composer and the owner of the recording for use by UWS. Royalty-­‐free music is not the same as copyright-­‐
free music, please ensure that if royalty-­‐free music is used that the music has been correctly licensed for use. For more information, please refer to the Copyright Policy and Intellectual Property Policy. Ø Music should be lowered while people are speaking so that voices can be heard clearly. Ø Final audio levels should sit between -­‐6db and 0db and peaking should be limited. Ø A copyright notice with ‘University of Western Sydney’ and the year of production needs to be incorporated ID3 tags. Other crediting needs to be in alignment with UWS Web Policy. Work completed by UWS students should also be noted. Compression Audio files should be AAC or MP3 with the appropriate file extensions of .m4a or .mp3. It is recommended that MP3 files greater than 32Mb be converted to the AAC file format. For AAC audio file it is recommend to use: Ø

Video Capture Ø Videos must be adequately exposed: o Use additional lights if indoors, consider framing carefully if outside in the sun or inside near windows. o No more than 30 percent of the frame should be over-­‐exposed. The preference would be for no over-­‐exposed regions. Ø Footage should be steady and level, unless the movement and angle have artistic purpose. Where possible, interviews should be filmed using a tripod. Ø Videos require high quality sound – always use an external microphone when recording interviews: o External microphones that record to their own memory device should be set to record in the highest quality option available. o Digital audio recording levels, particularly voice, should peak between -­‐12db and -­‐6db. Audio recorded higher than this range may result in unacceptable distortion. o Use headphones to check for unwanted noises. Be aware that electrical equipment such as computer towers, fans, air-­‐conditioning, kitchen appliances (especially refrigerators) and electric doors may produce unwanted noise. Ø Record at the largest frame-­‐size possible. o Standard Definition 16:9 (1024 pixels wide x 576 pixels high) is minimum screen resolution. o 1080p High Definition (1920 pixels wide x 1080 pixels high) o 720p High Definition (1280 pixels wide x 720 pixels high) o No video should be in a 4:3 aspect ratio. Ø Preferred frame rate is 30 frames per second. Ø All identifiable individuals in the video must sign and submit a release form outlining approval for publishing. A Photo Release form can be obtained from the UWS Photographer. Ø In the case of seminars and lectures: o Written permission must be obtained from the speaker both for the recording to take place and also for the University to publish the recording. Contact your Web Coordinator if you require a copy of the Licence and Copyright Agreement. o An announcement should be made prior to the start of the event that proceedings will be recorded. Post Production Ø Ensure native frame-­‐size and frame-­‐rate is maintained. Ø Footage should be graded so that whites appear white, blacks appear black and skin tones fall within the normal skin tone range. If a de-­‐saturated look is desired, whites and blacks should still show detail. Flexibility will be accepted for artistic pieces. Ø UWS Visual Identity Manual must be adhered to with regards to logo, image, colour and font usage. For more information, please contact iMedia for clarification. Ø A copyright notice with ‘University of Western Sydney’ and the year of production needs to be incorporated into the closing credits. Other crediting needs to be in alignment with the UWS Web Policy. Work completed by UWS students should also be noted. Ø Do not use any copyright music – all music must either be copyright-­‐free or have been released by both the composer and the owner of the recording for use by UWS.
