The existing frame and get the matched frame time

[davestephans]

Hi,

Can somebody help me with this requirement, pls?

The ultimate idea is to get the start and end time of a clip from a full length video.
Start time can be noted manually by playing the video. But the frame of end time clip should be compared with an existing frame and the accurate end time should be given automatically.

Right now it is stressful to forward the video by 1 frame/sec and watch the clip to identify the end time of the specific part of video.

Thanks in advance.

Start time can be noted manually by playing the video.

Or just press Ctrl+Shift+C which copies the PTS of the current frame to the clipboard.

But the frame of end time clip should be compared with an existing frame and the accurate end time should be given automatically.
