TECHNICAL FAQS

A technical adviser is available at iawm2015@wfu.edu to answer specific queries.

Q: What video frame rate, aspect ratio and pixel dimensions, encoding, audio bit rate, sample rate are acceptable for the Congress? And what other video specs should I use to convert European video for American local cable access?

When submitting audio or video files to the Congress the most important specification to ensure quality streaming is the bit-rate. Here are some MINIMUM requirements for audio and video files:

AUDIO SPECS: For compressed audio these are minimum suggested bitrates. Higher bitrates will result in better quality.

  • MP3—128kbps
  • AAC—96kbps
  • WAV (and other lossless file types, e.g. AIFF, ALAC)—16 bit at 44.1khz

VIDEO SPECS: Again, these are minimum suggested bitrates.

  • 7mbps for 720p
  • 15mbps for 1080p
  • Typical file types: MP4, FLV, MOV, WMF, AVCHD

If you plan to submit a HARD COPY of your presentation please write the file to a DVD-R. This allows for you to keep the file type you prefer and we won’t have to do any translating once we have received the file. This allows the most user control.

Q: I want to submit an event for live streaming during the Congress, April 13-19, 2015.  Musically I know what to do; however, I don’t know the technical requirements in order for the event to be streamed live during the Congress.  Any help?

To submit an initial proposal, follow the instructions on the Call for your category of event.  If your proposal is accepted, then please contact iawm2015@wfu.edu to work out a time on the Congress schedule that coincides with your event and the video specifics at the event site needed to stream the event.  Also, we encourage you to videocopy the live event, submit the videocopy to us, and allow us to replay it during the Congress after its live showing.

Q: How do we know that the Congress schedule will have room for my accepted proposal at the time it’ll be presented?  And must it be a public presentation?

All of the questions you have about live streaming of accepted events will be worked out between you and the technical associate at iawm2015@wfu.edu.  There is no requirement that the event be given in front of a live audience.  Room on the Congress schedule may become problematic, if most proposals describe events in the same time zone and hour, for example.  Because IAWM Congress 2015 and the membership of IAWM span much of the globe, our hope is that live events will be scattered here-and-there in a 24-hour clock, then–we hope–be copied to us  so it may be replayed at later times during the Congress.  That way, event offerings will be accessible more than one time to people in a wide number of time zones during the seven days.
