Hi there,
Anybody know of, or feel like writing a utility to scan video files MPEGs, AVIs etc for the gaps between "scenes".
The target market would be all amateur video photographers who tend to use their new toy more like a video snapshot camera and produce 90 minute tapes with loads of dross between the scenes.
That dross needs to be edited out and finding the stuff - almost frame by frame, takes an eternity.
These gaps are "normally" a few frames - or seconds, with the snowy interference pattern you get on a screen when the transmission ends but the TV is left on, or sometimes just black frames.
If the entire file could be scanned and an index built giving the position to within a couple of seconds, or frames - then it would make life so much easier.
I imagine it would be "simple" enough for the user to edit a few frames from an existing video containing nothing but the type of frame being sought and then saving this as a sample.
The sample would then contain a template of the data that triggers an entry into an index.
There are obviously dozens of CODECS but I think they are identifiable by the header and the saved sample would contain both the header and frame data.
I checked some commercial products with no success so it could be either too complex to incorporate into a sophisticated editing package or, hopefully, something nobody thought of writing as a simple standalone utility.
I would imagine a product like that could generate quite a lot of exposure for the originator.
