To explain why we can't jump to the next second involves not only I and P frames in the video stream but the ugly issue that there are usually 29.97 frames per second. At some point we'll be off one way or another 1/60 or more seconds.
But there is hope. VLC is open source at http://www.videolan.org/vlc/download-sources.html so your programming staff can rip it up to change the 10 to 1 seconds. It won't be exact due to the issues in paragraph one but might be close enough.
Can be done!
I am a mac person but I need to find a windows-based audio player (preferably a free one) that has the ability to advance by seconds. I am editing a video project in final cut pro and want my producer to do some of the logging of the video. Since he is on a PC, I am sending him audio-only versions of interviews (mp3's) and he is logging the transcription into an excel spreadsheet which I can then import into Final Cut Pro, adding his notes to the original video. The only problem is he is using windows media player, which only allows you to move the playhead forward and backward in 10 second increments. If all the in-points are 10 seconds off it doesn't do me much good so I need something that will allow him to move the playhead forward and back one second at a time. VLC's "frame by frame" feature is the closest thing I have found but it only works with video. Any suggestions?
