I recorded audio with Ardour and video with a separate camera. I used the old fashioned clapboard style of making sure video and audio were lined up, since the audio recording started a second or two before the video recording started, and I was using consumer style equipment which did not have timecode.
So now I have a video file, which I imported into the Ardour timeline, and an audio file which started in Ardour, and which I then trimmed and moved slightly to line up with the video.
What I would like to do is trim the beginning and end of the video to get rid of some dead space (including the clapboard). Since I lose the clapboard when trimming off the beginning of the video, is there any good trick to make sure the audio stays lined up? I will probably be using kdenlive or similar to trim the video, so do I just have to keep track of how much I trim off, then trim the same amount from the Ardour timeline?
This seems like it would be pretty trivial with timecode, is there any way to retroactively add time code to the video file and to the Ardour timeline? I think I can generate timecode with some of the x42 tools, mux that with the original video file, and then when I trim in the editor hopefully the time code will still be readable. Seems cumbersome, is there a better way that I’m just not seeing?
