why do the clips not start at 00:00:000 in the source window?

thankyou guys,

im editing from a list of instructions. the notes im given are assuming the clips start at 0 so this is the reason i need it to be 0

thanks for the quick replies

As Averdahl mentioned, your camera is recording timecode differently than resetting to 0:00 on each clip. Seems to be using regenerating timecode which means it does not reset, but rather refers to the end timecode of the last clip and continues from there. I also agree with Averdahl that this isn't necessarily a bad thing, and people do chose to work this way (or work off of continuously rolling timecode with something like time of day) because it gives you a better sense of where in the context of your shoot a particular clip is.

However if you really didn't want to work with the media timecode, you could go to Preferences > Media and you change the timecode setting from "Use Media Source" to "Start at 00:00:00:00". I've never changed that setting myself, but that should stop referring to the media timecode in your source window, and just start with 0. If that doesn't work, you could right-click the clips in your bin and select Modify > Timecode and change the actual timecode on the clips.

By the way your right-most circle that you highlighted (time in grey) isn't exactly timecode, but IN to OUT duration. In the absence of an IN/OUT point, it is the duration of the entire clip.

What you see is the Media Start timecode of the clip, the same timecode that you can see for the clip in the Project panel.

Depending of the camera used you can get every clip to show 00:00:00:01 if you move the .MXF file out from the original folder/s you copied from the camera to your HDD. In my opinion what you see is what you really want to see to get a better editing experience, to get a better overview of the footage used.

You really don´t want to move the .MXF files out of their original folder structure for other reasons as well.
