What are the compatible stimuli formats for InterVu?

The table below outlines the various file types that are compatible with InterVu, along with best practices for each. File types are organized by stimuli format.

Format	File Type	InterVu Recommendation	Notes
Images	JPEG, PNG, GIF	InterVu recommends that image files be 50mb or less. InterVu automatically resizes image files to the user’s resolution.	Saving image files as PDF allows for resolution independent zooming (vector based) that is beneficial with HQ images. Note: You can send images as separate files to allow for individual uploading and layout creation.
Documents	PPT, PPTx, PDF (No Word documents)	InterVu recommends documents are in PDF format, up to 50mb, as it will upload quicker for the user and allow for more navigation abilities. (zooming, panning, rotation)	Document files should not include animation, as they will not all transfer into the InterVu platform. They should also not include embedded audio files, as they will need to be uploaded separately as an MP3 audio file. PDF files cannot be password protected, as they cannot be viewed/uploaded in the InterVu platform. Note: You can send documents as separate files to allow for individual uploading and layout creation.
Video	MP4	InterVu recommends that video files are in MP4 format, up to 30mb. We recommend that the file be no more than 30fps/500kbps for the best overall user experience.	Embedded audio will play through everyone’s computer speakers during playback, so the InterVu technician will mute all phone lines to eliminate feedback.
Audio	MP3	InterVu recommends that audio files are 50mb or less, and no more than 128kbps for the best overall user experience.	Audio files will play through everyone’s computer speakers during playback, so the InterVu technician will mute all phone lines to eliminate feedback.
Screen Sharing	Desktop/Laptop (PC/MAC)	Adobe Connect application required.	In order to initiate a screen share a user will need to install the Adobe Connect Add-In. The audio from a screen share will be local to the user sharing their screen, so any audio will be picked up through their phone and shared with the other users.
Polling Questions	Word document	Questions – 1,000 character limit Answers: MC/MA – No limit Answers: SA – 250 character limit	The easiest method to send polling questions to have uploaded into your InterVu room would be to send them in a Word document, and outline the following: Questions in number order in regards to when you want them to be displayed Label what format the question should be presented. (Multiple Choice, Multiple Answer, or Short Answer)

The following limitations and considerations apply when uploading files to InterVu:

• FocusVision is unable to edit client stimulus, so please send files as you wish them to be displayed in the room with any special instructions.
• The file name will be displayed in the meeting room, so please mask file with generic name, if needed.
• All stimuli should be sent to [e-mail] with your FocusVision project number in the subject of the email.
• We recommend sending stimuli at least 2 business days in advance, to allow for uploading of the materials and to leave time for the moderator to test them in the online meeting room.
