TwistedWave Online
Video sync
Load a movie in TwistedWave Online and the video plays along with your audio. Edit the sound, save the movie with your changes, and even have the picture follow your edits.
Video sync
The picture plays along with your audio
When you load a movie, the video appears just above the waveform. Place the cursor in the audio and the matching frame appears; play back, and the video plays along, so you can see exactly how your audio works with the picture.
Edit the soundtrack
Edit the audio track of a movie
TwistedWave Online doesn't just open movie files, it saves them back with your edited audio track.
- Edit out unwanted sounds,
- remove background noise,
- add sound effects.
When you save, the edited soundtrack is written back into the original video. The images aren't re-encoded, so the full quality of the original video is preserved (unless you choose a different video codec).
Synchronized editing
Edit the movie by editing the audio
The button over the video preview switches it between "Unedited Video" and "Edited Video". Once it shows "Edited Video", the picture follows every edit you make to the audio:
- Cut audio, and the matching images are deleted.
- Reverse a selection, and the video plays backwards.
- Slow down or speed up the audio, and the video matches.
Editing a vlog? Select the extra silences in the waveform and delete them, and the matching footage goes with them.
Longer movies
Update your subscription
TwistedWave Online lets you test video editing on files up to 30 seconds long.
To edit longer files, upgrade your subscription plan and select the video option.
No quality loss
Preserve the full image quality
When you save a movie, TwistedWave does its best to preserve the full image quality. If you are not using synchronized editing and simply save the audio back with the original video, TwistedWave doesn't even re-encode the images (unless you have chosen a different video codec): the original frames are re-used, and the full quality is preserved.
If you have edited the video, some re-encoding has to happen. Reverse or slow down a region and the matching images are re-encoded; cut or paste audio and only a small region around each cut is re-encoded, depending on the position of key frames.
And if every frame in the video track is a key frame, such as Motion JPEG or h264 set to all key frames (the ALL-I / ALL-Intra setting on some cameras), TwistedWave never has to re-encode a frame, and re-uses all the original frames even when you reverse or slow down a region.
