The DAVE Project actively seeks high quality content covering a diverse array of subjects within the field of gastroenterology.
RECORDING AND EDITING VIDEO
For help setting up equipment for recording video, please see How to record and edit endoscopy videos – Part 1: Equipment set-up .
INSTRUCTIONS TO AUTHORS
The Digital Atlas of Video Education (DAVE) Project publishes original high quality academic works involving gastroenterology, gastrointestinal endoscopy, and pathologic conditions involving the liver and gastrointestinal system. Submitted content is peer reviewed. Content is revised through the peer review process and at times, members of the editorial staff may work with authors to revise submissions prior to publication. Incomplete or incorrectly formatted submissions may be returned to the authors prior to peer review for correction.
To request an account to upload content, contact us via our online form. Please include your name and organizational affiliation.
Submissions should conform to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals (http://www.icmje.org). Authors should ensure that submissions have not been published elsewhere, that all authors have contributed, and that conflicts of interest have been disclosed. Research studies involving patients or animals must have the approval of the institutional review board.
Contributions to the DAVE Project comprise the majority of the material in the library and are strongly encouraged. Original content will be considered for publication under the assumption that credit will be given for material that has been previously published in written form and or online.
English is the language for text submissions as well as narration of video segments. All accepted works are subject to editing for clarity, accuracy, syntax, syncopation of audio and video segments, and style.
The submission process begins with establishing a login for the DAVE project website. If you have material you would like to contribute, please contact us via our online form.
The length of the clip should be governed by the complexity of the material.
A “Findings” clips is intended to demonstrate the classic endoscopic appearance of a finding, or abnormality. Generally these clips are approximately 2 minutes long, and include histology and/or radiology to further their didactic impact. A written narrative must accompany all digital video submissions. The narrative typically includes a 1-2 sentence introductory statement of clinical background, a review of other diagnostic studies such as radiologic imaging, a description of the classic endoscopic findings, a brief review of relevant pathologic findings, and a concluding didactic statement.
A “Procedure” clip is often longer, up to 15 minutes, and is intended to demonstrate in detail how a particular technique is performed. These clips may require multiple video inputs for example, endoscopy, fluoroscopy, and EUS streams. A written narrative must accompany all of the “Procedure” clip submissions.
DIGITAL VIDEO FORMATTING GUIDELINES
1. Transitions should be selected in a consistent pattern. A limited palette of transitions typically improves the educational quality of the videos. When changing clips between similar subjects such as going from a colon endoscopy sequence to another colon endoscopy sequence, and one desires minimal transition effect, use the “cross-fade” transition. This will essentially blend the first clip into the second. When changing between similar subjects as above but one wants to call attention to this change, use the “fade to black” transition. This is useful when changing from a sequence showing normal colon to a sequence of colon showing an abnormality. When changing to an entirely different medium, use the “face” transition. This will warn the viewer that the upcoming sequence is entirely different. This “face” transition is particularly useful between microscopy clips when changing from low power to a higher power clips as it mimics the rotation of the lenses on a microscope. More dramatic transitions such as a “flying cube” or a “flying flip” tend to be distracting and thus should be used sparingly.
2. Pauses. The average viewer requires 4-5 seconds to focus and digest a new finding on a single frame or finding.
3. Volume. One of the most common errors in submission is that the volume of the initial submission is too low. Please make sure that your playback volume is high enough so that it is audible at the mid-range of your computer speaker setting. The editors can easily adjust the volume downward on a submission. They cannot easily increase the volume without generating artifact. Also, during your narration, please avoid long pauses in your your narrative as this may confuse your audience into thinking there is a transmission defect. Again, it is very important to submit a type narrative to accompany your submissions.
Title / author information
The written narrative must include author(s) names and institutional affiliations. One author will be designated as the corresponding author and all subsequent correspondence will be directed to this contact. Email is the standard mode of communication for the DAVE Project.
CONFLICT OF INTEREST DISCLOSURE
All submissions must include a complete disclosure of any conflicts of interest that the authors may have.
Laboratory values should be presented in SI units. For conversion from non-SI units see http://www.techexpo.com/techdata/techcntr.html. Following laboratory values, normal values should be presented in parentheses in the text.
Spell out abbreviations the first time the terms appear in the text. You may follow the list of standard abbreviations found in the AMA Manual of Style, 10th edition.
VIDEO, IMAGES and FIGURES
Figures and images typically accompany segments of endoscopic video. The DAVE project makes images available for download at the time of the download of the video segments. Images should be of high resolution. Accompanying images are submitted online separately as Figures which will be posted with the original video and made available as standalone files at the time of downloading. Figures should be saved at the highest resolution possible.
All videos or graphics submitted must be of the highest quality possible.
Submissions of videos that were originally recorded through the S-video or RGB outputs of the endoscope processor are desired.
The DAVE Project may edit any video or computer graphics. Reviewers, following the usual policy with illustrations, may suggest changes in the video or computer graphic.
A sound track “narrative” is required.
The following formats for video will be accepted: MPEG-2 (.mpg), MPEG-4 (.m4v or .mp4), Quicktime (.mov or .dv), or Windows Media video. MPEG-2, MPEG-4 and DV video is preferred.
For journal article reviews, narrated PowerPoint or Keynotes files are accepted.
References must be cited in the text in consecutive order and identified by superscript numbers.
It is the author’s responsibility to check the accuracy of all references by verifying them against the original documents. Citations can be verified by using PubMed’s Citation Matcher.
Examples of correct forms of reference, in accordance with Uniform Requirements for Manuscripts Submitted to Biomedical Journals are given in the online submission instructions. Follow Index Medicus for journal title abbreviations.
If excerpts from other copyrighted works are included, the author(s) must obtain any necessary permission from the copyright owners and credit the source(s). These permissions must be submitted to the Editorial Office before publication can occur.
The DAVE project uses formatting consistent with the New England Journal of Medicine. NEJM formatting can be specified in programs that manage the referencing such as ENDNOTE.
