Which transitions are available in the browser studio?
The timeline supports the everyday edit transitions: cuts, cross dissolves, dips and wipes, plus custom moves built in Fusion. Check the current effect browser rather than assuming a third party preset pack is installed.
Why will a dissolve not apply to my clip?
The most common reason is a missing handle: there are not enough frames beyond the cut for the two clips to overlap. Trim with extra media on both sides, then place the transition again.
How long should a transition be?
Long enough to do its job and short enough to keep the scene moving. A dissolve between two shots often sits around half a second to a second, but the right duration depends on the action and the music.
Should the audio crossfade too?
Only when the sound should change with the picture. A hard audio cut under a picture dissolve can be more effective than fading everything. Listen for dialogue, room tone and music cues before choosing.
Can I use the same transition on vertical video?
Test it on the vertical frame. A wipe or graphic move designed for a 16:9 frame can lose its meaning when the sides are cropped. Rebuild or reposition the move for the delivery aspect ratio.
Does Fusion make a transition render slower?
A complex Fusion move can cost more than a native dissolve, especially on a long timeline. Preview the heaviest section first and use render cache or proxies if the sequence starts to stall.
