Creating a Timeline With Handles
If you need to render media with handles before exporting a timeline to another application, you can create a duplicate version of a graded timeline (or of the Master timeline) in the Conform page first. A timeline with handles is useful if you’re recording a timeline to tape and you need pre-roll time.
To create a timeline with handles:
1. Open the Conform page and select any timeline, or the Master timeline, you want to duplicate into a timeline with handles.
2. Do one of the following:
> Choose File > New Timeline With Handles.
> Right-click the Master timeline or any other timeline in the Timelines list and choose “Create New Timeline With Handles.”
The Timeline with Handles Setup dialog appears.

3. Adjust the following settings:
> Pre Handle Value (Frames) field: The number of frames to add before the In point of the clip.
Type a number in the field, or use the up/down arrows to adjust the value a frame at a time.
> Post Handle Value (Frames) field: The number of frames to add after the Out point of the clip. Type a number in the field, or use the up/down arrows to adjust the value a frame at a time.
> Source Mode checkbox: Sorts the clips in the new timeline in ascending order, according to source timecode.
> Force Black Handles checkbox: For clips that lack extra media at the head or tail, turning on this checkbox renders black instead, creating handles where previously there were none.
4. When you’re finished, click OK, and when a Conform Settings dialog appears, verify the settings you selected and click OK a second time.
5. If you want, type a custom name for the new timeline in the Timeline Name dialog that appears, and click OK. By default, the new name is that of the previous timeline with “(Handles)” appended to it.
A new timeline is created, with clips that are longer to reflect the handles that were added.
Keep in mind that timelines with handles have a completely different timing then the original timeline, and are not meant to be used, played, or exported in place of the originally graded timeline. Timelines with handles are only meant to be used to output to tape with handles, or to render media with handles in a different way, for example, to add handles that you can use to extend motion tracking that’s being applied to one or more windows. To export an EDL or XML file, select the originally graded timeline first.
Note: If you simply want to render Media with handles, you can use the “Add x Handles” setting in the Output options of the Render settings when rendering your program in the Deliver page.
If you really want to have Blackmagic *fix* this *issue*, can you confirm that it doesn’t work, first?
