Hi John, all,
For further clarification, there are a few things you need to take into account:
1. Video source: as we all know there are thousands of different video sources out there and often the initial requirement is to get the video into a viewable format without dropping frames. So you need to make sure that if you are converting that you have something that can convert from different formats and you need to ensure that you do not drop frames.
2. Related to the first comment, you need to make sure that you are using a solution that has a complete audit trail so that you can authenticate the processes that you undertook to alter the video (you are changing it and as mentioned in an earlier post, keeping an original copy of the video and working off an a "working copy" is advised.
3. To apply various annotation features such as blurring/ complete masking etc can be a time consuming process and a lot of solutions require you to do this process frame by frame. What we would advocate is that you use a solution that allows you to track a moving object e.g. a person entering and existing the scene, apply the appropriate blur/ masking features using key frames (rather than frame by frame). It speeds up the process. Furthermore, if you have multiple objects in the same scene that you are trying to blur you need to be able to "lock" and the edit you have just done and then progress with masking/blurring other objects without affecting the one you have just done.
If you need further clarification let me know.
