How To Submit Content to The DAVE Project
Contributions to the DAVE Project comprise the majority of the material in the library and are strongly encouraged. If you have material you would like to contribute, please use the contact form to request login information to our FTP upload server. Materials can be submitted in their fully edited and narrated form or can be submitted in pieces to be edited and narrated by our editors.
Ideally, all video submissions should be in MPEG 2 format. The length of the clip will 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 should accompany all submissions. The narrative should include a 1-2 sentence introductory statement of clinical background (this can be omitted if noncontributory), followed by a description of the classic endoscopic findings, then a brief review of the relevant pathology and/or radiology findings, and then a concluding didactic statement about the finding.
A “Procedure” clip is often longer, up to15 minutes, and is intended to demonstrate in detail how a particular technique is performed. These clips may require multiple video inputs for example, fluoroscopy, and EUS as well as endoscope inputs to capture all relevant aspects of the technique. A written narrative should accompany all of the “Procedure” clip submissions as well.
Here are suggestions regarding editing techniques and transitions:
1.Transitions should be selected in a consistent pattern. We now use only four styles of transitions between video sequences depending on the desired effect of the transition. 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 “crossfade” (names as used in the ULead Video Studio 9 software) 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. Occassionally a more dramatic transition is used such as a “flying cube” or a “flying flip”. These more dramatic transitions tend to be distracting and thus are used sparingly.
2. Pauses. The average viewer requires 4-5 seconds to focus and digest a new finding on a single frame or finding.
