Usage Scenarios

AI Audio Stretch plays a vital role in many scenarios.

• One situation is when a vlog with multiple scenes and different music clips, you would expect these short videos to combine into one video. Audio set at an ideal time is a natural way to link these valuable memories.
• Another circumstance is a vlog with the same music, but the music time doesn't match the video time. You might face it when you process a long video with only one piece of music. AI Audio Stretch is needed to avoid repeating the same melody monotonously several times.
