| Much to my home audience's disgust somewhere in my tool chain of DVC -> firewire import -> encode to MPEG2/DVD -> create VOB's -> burn to DVD+R some scenes are repeated in the output video. I think the import is too blame, but now I don't really care, I just want to fix it.
I assumed that somewhere there would be an application that could read an MPEG2 file, show me a list of scenes, let me delete some and then save out the resulting video WITHOUT reencoding it. (GOP accurate editing is not a problem)
And there seem to be a few that allow you to do just that, but you have to sit there for hours watching the film (yes the source is at least 5-6 hours of video) waiting for the dupelicate scenes and then manually find the scene edge, select the scene and then delete it.
Wow, like a have 5 hours to waste doing that. What I need is something that gives me a high level overview of the video, like a list of scenes, with keyframes across the page and each row being a scene, so I can quickly pick out the scenes I want and don't want. This seems so obvious that I thought they'd be 100 freeware/shareware apps out there doing it.
Apparently not. Or am I just blind?
Also I can imagine such an application would be dead handy at removing commercials from captured TV, not that I capture TV to MPEG2, but the same app could be made to work with AVI files as well with a little work.
Update
This is a mock up of the UI I'm thinking of, a list of scenes down the page with "one click" delete ability. Then hit save and out comes a new video file minus the deleted scenes but not re-encoded at all. (GOP accuracy is fine).

| One would think this would be easy, I assume you've checked in Premiere and AVID right? The only software I've seen this in is Virtualdub but it's for avi only. Could be a issue with the mpeg2 format too, it's old and not very efficient. |

| As a coincidence I was checking some video editing options and this one came up.

"Native MPEG editing with smart rendering. Edit MPEG material without unnecessary rendering - only changed frames are rendered."
It's a plugin for premiere. |

| Tozz: I've added a mock up of what I'm looking for... most apps only have one linear timeline that you have to navigate to find the scenes manually. This is not particularly helpful. Maybe premier has a mode like this that I don't know about?
I'm trying to decide whether it'll be quicker for me to write an app to do it or just slog through it the hard way. |

| woa.. hmm, that would require the file to have chapter information in it, to my knoweledge mpeg2 doesn't support this. Closest would be DVD with chapter information but that requires all those .ifo files with information.
I'm out of clues :) |

| The film doesn't need chapter information, there are ways of detect scene changes simply by analysing the frames. VirtualDub does this already, so it can't be too hard.
Bah. Looks like I'm writing the tool myself. |

| Well scenechanges aren't that reliable :) But yeah, if that's all you want there should be something out there that does it. |
