A Batch FX is created by bringing a selection of timeline segments into a BFX level. You enter a BFX level from the EditDesk record timeline or from the timeline of the clip in the current BFX level. You can bring segments with their soft effects into a BFX level. A Batch FX is applied on top of the segments and their soft effects. Or, you can enter a BFX level with a single segment's source, leaving its soft effects intact on the timeline one level up. A Batch FX is applied to the source before anything else affects it.
To apply a Batch FX to segments and their soft effects, you enter a BFX level with the Post option. You can enter with a contiguous selection of horizontal or vertical segments. Bringing in multiple segments is useful for continuing work that was done in context of the EditDesk record timeline or for bringing a selection of segments into the same Batch FX level.
To apply a Batch FX to a source and not its soft effects, you enter a BFX level with the Pre option. You can enter with only one segment. Bring in only a source to make changes such as removing pulldown that you want to do before the soft effects. When you go back to the EditDesk record timeline, the soft effects are reapplied to the modified source.
Each time you access a Batch setup, you enter another BFX level. A clip can therefore have multiple nested Batch setups. Whether you enter a BFX level from the EditDesk record timeline or from the current BFX level, you enter with the Pre or Post option.

In the following example, the Flip effect is part of the new source segment. If you bring the segment into a new BFX level with the Pre option and create a Batch FX, the setup is applied to the modified source.
(a) New source segment
You can select multiple segments or a specific segment. If you select multiple segments, they must be contiguous horizontally or vertically. However, it is not necessary to select an entire stack of vertical layers.

The segments along with their soft effects are loaded as a clip in a new Batch setup. In the following example, the Axis Key and Text soft effects are brought in with both layers from the EditDesk record timeline.

If you did not make an explicit selection on the record timeline and in and out points were set, all segments on all layers between the in and out points are brought in. If in and out points were not set, only the segment under the positioner's focus point is brought in. Head and tail frames are displayed for reference.

To modify the source and its soft effects, drag a node to the process tree and adjust the settings. In the following example, a Flip node is applied on top of the original front segment and its Text soft effect. See .
The Flip Batch FX is applied on top of the original front segment and its Text soft effect. The segment is pale magenta indicating that a Batch setup is applied to the clip. A black BFX icon indicates that the Batch setup is also applied to the clip's soft effects. The soft effect indicators are not displayed because a Batch setup has been applied on top of the soft effects. Enter the Batch setup to access the soft effects.
If you entered Batch with more than one layer, the layers are collapsed into one segment on the bottom layer of the original selection. The segment takes on the length of the original selection or the length defined by the selection's in and out points.

Creating Batch FX is an iterative process. You can apply a Batch FX to a segment in any Batch level. In the following example, the segment with the Text soft effect is brought into a new setup (BFX 2) with the Post option. A Paint node is applied to the clip and its Text soft effect.
