We are working on a video processing application, which requires n video streams as input. These n streams are typically captured from n cameras covering a "scene". For processing, this application requires that these n video streams be of the same duration and perfectly synchronized. We are looking at an editing software to provide us video streams which meet these requirements. Some of the problems we could think of as reasons for a lack of synchronization in the "raw video" streams are: * All n cameras may not have begun recording at the same time * One of the cameras may not have recorded a portion of the scene * Some cameras may have recorded additional content in that scene, which needs to be edited out., etc. 1. How can we achieve this "synchronization" of n separate streams using an AVID setup? 2. If a single video source, that is brought into an AVID environment, has multiple IN-OUT points marked, how are these individual portions of the source placed on the timeline. When creating a final output of the video stream, does Avid automatically pick up only the "marked" portions of the video? 3. Can a IN-OUT marking that is made on one video track on the timeline be propagated automatically to other tracks on the time line after they have been synchronized? 4. Since we need to record each track as a separate stream, once the editing and synchronizing is done, we would like to know about the following situation: suppose recording begins from time zero, i.e. absolute beginning of the track on the timeline, and the video data begins only after a certain time on the track, then will the recording contain "blank" portions for those parts of the track where there is no video or audio available? 5. If the "raw video" input also contains an audio track, how does Avid treat the source. Can Avid "separate" these two? 6. Given the objective stated above, how can AVID's EDL help us? 7. Can the synchronization and editing of video tracks also be propagated to audio tracks? 8. If the "raw video" or source footage is "pre-edited" and contains "supers", or other sub-title information, does Avid provide any tools to "remove" such graphics, text, titles, etc.? 9. What is the format of the output video? What are the options in terms of file formats, viz. AVI, QT, Mpeg-1, Mpeg-2, etc.? What is the OMF format? -----== Posted via Deja News, The Leader in Internet Discussion ==----- http://www.dejanews.com/ Now offering spam-free web-based newsreading
