How do I sync audio and video in power director?

CyberLink PowerDirector is a popular and full-featured video editing software for consumers and professionals. It allows users to edit, enhance, and finalize their videos. Some of the key features of PowerDirector include advanced editing tools like multi-cam editing, keyframe animation, a range of visual effects, and audio editing capabilities. It also makes it easy to sync audio and video clips together.

However, in some cases the audio and video tracks may fall out of sync during the editing process. This can happen if the source clips had variable frame rates or inconsistent timestamps. Thankfully, PowerDirector provides options to manually sync or auto-align the audio with the video to fix any sync issues.

This brief overview introduces PowerDirector and the topic of syncing audio and video within the software, setting the stage for the steps to follow.

Prepare Your Audio and Video Files

Before syncing audio and video in PowerDirector, it’s important to start with files that are in a supported file format. PowerDirector supports a wide range of formats for both audio and video.

For video, PowerDirector supports formats like AVCHD, MPEG-2 HD, MPEG-4, H.264, MOV, and more. Common formats like AVI, WMV, MP4, and MKV are also supported.

For audio, PowerDirector supports formats including MP3, WAV, WMA, AAC, and more. Make sure your audio files are in a standard uncompressed format for best syncing results.

Check the CyberLink website for the full list of supported media formats in your version of PowerDirector. Any files not in a supported format will need to be converted before importing into PowerDirector.

Import Media into PowerDirector

Once you have gathered your audio and video files, you can import them into the PowerDirector media library to start assembling your project timeline. PowerDirector makes it easy to import a variety of media formats.

To import media files:
– Launch PowerDirector and click the “Media Room” icon on the main interface.

– Drag and drop your video and audio files directly into the media library panel.
– You can also click “Import Media” and select the files you want to add from your computer folders.
– Supported formats include video files like MP4, MOV, MTS, and audio files like MP3, WAV, and more. PowerDirector supports a wide variety of media formats.

Once your media is imported, you can start adding clips to the timeline to assemble your edited video. Simply drag clips from the media library onto the timeline tracks to start syncing audio and video.

Sync Options in PowerDirector

PowerDirector offers a few different options for syncing audio and video clips in the timeline.

One option is to sync based on the timecode embedded in the files. Professional cameras and audio recorders will record timecode information directly into the metadata of the files. If your files have matching timecode, you can use this to perfectly align the audio and video clips in PowerDirector.

Another option is to sync based on the date and time the files were created. Most cameras and audio recorders will embed the file creation date and time into the metadata. You can use this timestamp to sync files that were recorded simultaneously but don’t contain matching timecode. Just line up the clips with the same timestamp in PowerDirector and they should be in sync.

PowerDirector also offers an auto-sync feature that analyzes the audio waveform and automatically matches it to the video clip. This works fairly well for basic syncing but may not be frame accurate. Manual syncing based on timecode or file creation time will give the most precise results.

Sync Audio and Video Manually

The most precise way to sync audio and video is to do it manually. This involves zooming into the timeline and matching up the waveforms of the audio and video tracks. Here are the steps:

1. Import your separate audio and video clips into PowerDirector. Place them on top of each other in the timeline.

2. Zoom in as far as possible on the timeline so you can see the waveforms of both the audio and video.

3. Play through the timeline. Look for spikes or dips in both waveforms and sync them up visually. Line up the waveforms so that spikes and dips are happening at the exact same time.

4. Use the audio or video trim tool to precision trim the start of one clip to perfectly line up with the other.

5. If needed, expand the audio clip in the timeline to match the duration of the video clip.

6. Play through the synced clips. Make any additional minor adjustments to the trim or alignment to perfect the sync.

The advantage of manual syncing is it allows for extremely precise alignment of the audio and video down to a single frame. The downside is it can be very time consuming if you have many clips to sync up.

Use Auto-Sync

PowerDirector has an Auto-Sync feature that analyzes the timecode and waveform of your video and audio files to sync them automatically. Here’s how to use it:

Import your separate audio and video clips into the timeline. Make sure the audio track is above the video track. Select both tracks, right click and choose “Auto Sync Audio/Video”.

PowerDirector will analyze the timecode and waveforms, and align the audio track to the video track by adding/removing silence at the beginning of the audio as needed. This works best if the audio and video have matching timecodes or were recorded simultaneously. The Auto Sync is quite accurate in most cases.

One limitation is Auto-Sync only works with one audio track and one video track at a time. If you have multiple audio or video clips, you will need to manually sync them.

Sync Based on Timestamp

One way to sync audio and video in PowerDirector is to rely on the timestamp metadata embedded in the files themselves. Most digital cameras and audio recorders will encode files with timestamp information indicating when exactly the media was recorded.

PowerDirector can leverage these timestamps to automatically align the separate audio and video files. This is done by matching the date/time stamps between files during import and syncing them accordingly.

For this method to work properly, it’s crucial that both the video and external audio were recorded using devices with accurately set internal clocks. Any discrepancy in the time settings will lead to sync drift.

Additionally, the timestamp meta-data must be intact within the media files. If the timestamp is missing due to file conversion or other issues, PowerDirector will not be able to sync using this method.

Overall, syncing based on timestamp can be a quick and easy option if your hardware encoded reliable timecodes. It avoids the need to manually align the audio waveform. But it’s effectiveness fully depends on accurate timekeeping during the initial recording.

Tips for avoiding sync issues

There are a few things you can do when recording your audio and video to help avoid synchronization problems in the first place:

  • Record audio and video together – Having the audio and video originate from the same source at the same time will ensure proper sync. Use a camera that can record audio or connect an external microphone to your camera.
  • Use a clapboard – Recording a visual and audible sync point like a clapboard snapping shut gives you a reference point to line up audio and video in post-production.
  • Avoid variable frame rates – Certain cameras allow variable frame rates that can drift and cause sync issues. Record using a constant frame rate.
  • Monitor audio while recording – Use headphones to listen to recorded audio to ensure proper levels and quality.
  • Avoid audio compression – Compressed audio formats can introduce variable delays that affect sync. Record uncompressed audio if possible.

Carefully recording high-quality synchronized audio and video from the start will minimize difficult syncing issues during editing.

Fix sync drift

If you notice the audio and video slowly becoming out of sync as your project progresses, you likely have sync drift. This is caused by differences in sample rate between your audio and video files. To fix it in PowerDirector:

1. Locate where the drift begins. Play through your timeline and note the exact spot where the audio and video fall out of sync.

2. Select the clip where the drift starts. It’s usually best to slip the audio rather than the video.

3. Use the Slip tool in PowerDirector to slide the audio or video clip so it lines up with the other again. You can nudge it in tiny increments to precision sync it.

4. Repeat this slip adjustment wherever you notice drift occurring in the timeline. It may need small fixes in multiple places.

You can also try using Compressor to transcode mismatched media to the same frame rate prior to import into PowerDirector. Recording matched audio/video will prevent drift from occurring in the first place (1).


Properly syncing audio and video is crucial for creating professional-looking videos with PowerDirector. By preparing your files appropriately before import and utilizing the sync tools within PowerDirector, you can efficiently align your audio and video tracks.

To quickly recap, you have three main options for syncing: manual sync by aligning audio and video visually, auto-sync based on matching waveforms, and sync by matching timestamps. While auto-sync can save time, it’s not foolproof and may require some manual adjustment. Monitoring your tracks closely and making sync adjustments as needed is key.

If you run into drift between already synced clips, tools like anchor sync can quickly realign them. With some care taken during setup and post-production, you can avoid major sync headaches and produce perfectly timed videos.
