SyncDepo Help Center

Everything you need to sync, QC, export, and deliver your video depositions.

The Start Page

When you open SyncDepo and log in, you will be presented with the start page. From here you can create a new synced deposition, open an existing one, view your sync queue, view your settings, or exit the program.

Creating a New Synced Deposition

To create a new synced deposition, click the "New Sync" button on the start page.

Start by clicking the "Select Transcript File" button and choose a TXT transcript file from your computer.

New sync transcript selection
Selecting a transcript file for a new sync.

A note on transcript formats

SyncDepo accepts standard legal transcripts in ASCII TXT format. Lines must be numbered, and any extra information in margins (timestamps, etc.) must be removed.

Once you have selected a transcript, the transcript will appear in the preview area. Fill out the required metadata fields to continue. SyncDepo automatically detects the witness name, volume, date, and lines per page, but you can edit the fields as needed.

SyncDepo will also try to automatically detect the videographer's read-on. Lines before the read-on appear in light gray. If the detection is incorrect, right-click a line and select "Mark as Read-On."

Check these two fields

Double-check the "Line #'s Start at Page" and "Lines per Page" fields. If these values are incorrect, your final sync file will also be incorrect. Choose the first page with line numbers and ensure the preview matches the original transcript.

Selecting video files

Once you've filled out the metadata, click next to start adding your video files. You can add as many video files as you want — but make sure they are in the correct order, and that none are missing!

New sync video selection

Video format

SyncDepo accepts standard H.264 encoded MP4 video files. Use tools such as Handbrake or ffmpeg to convert videos if necessary.

When you are ready, click "Confirm." Once submitted, your sync job will be added to the Sync Queue, and you will be directed to the Sync Queue page.

Recommended Video Format

To make uploads fast and ensure your video plays correctly in SyncDepo, please record (or export) your deposition video using these settings. Most modern cameras, recorders, and editing software support all of them.

Setting Recommended Value
File type / containerMP4
Video codecH.264 (sometimes labeled "AVC")
Resolution1920 × 1080 ("1080p" or "Full HD")
Frame rate30 fps
Video bitrate2,000–4,000 kbps (2–4 Mbps)
Keyframe interval (GOP)2 seconds (60 frames at 30 fps)
Audio codecAAC
Audio bitrate128 kbps
Audio channelsStereo
Audio sample rate48 kHz
Fast startEnabled (often labeled "optimize for web"; -movflags +faststart in ffmpeg)

A one-hour deposition recorded at these settings is typically 1–2 GB.

Why these settings?

  • 1080p at 30 fps is plenty. Depositions are mostly a single seated witness — higher resolutions (4K) and frame rates (60 fps) produce much larger files without improving the record.
  • H.264 + AAC in an MP4 container is the most universally compatible format. It plays everywhere — SyncDepo, court video systems, TrialDirector, web browsers — without conversion.
  • Smaller files upload faster and get synchronized faster. A 5 GB file can take 10× longer to upload than a 1.5 GB file of the same deposition.
  • A 2-second keyframe interval makes seeking more accurate. Encoder defaults are often much longer.
  • Fast start improves video load times.

Please avoid

  • 4K resolution — unnecessary for a talking head and slow to upload.
  • 60 fps — doubles file size with no benefit for deposition footage.
  • H.265 / HEVC — not all systems can play it back reliably.

Audio matters most

The transcript synchronization depends on clean audio more than anything else. A well-placed lavalier or boundary microphone on the witness, recorded at a healthy level (peaks around -6 dB, no clipping), will produce dramatically better sync results than any video setting choice.

If your camera or recorder doesn't offer these exact settings, choose the closest match — or contact support@syncdepo.com and we'll help you find the right options for your equipment.

Sync Queue

Submitted depositions appear in the sync queue. The Sync Queue is split into two sections — the "Pending Jobs" section and the "Submitted Jobs" section. Pending jobs haven't been uploaded to our servers yet, and can be canceled without using any credits. Jobs go through three steps in the pending section before being submitted:

  1. Pending: The job is waiting for other pending jobs to be submitted before starting.
  2. Extracting: The audio is being extracted from your deposition videos for use in the syncing process.
  3. Uploading: The audio and transcript are being uploaded to our servers for syncing.

Once Submitted, jobs will begin syncing. Once done, the status will be changed to "Complete", and the download button will appear.

Queuing jobs

You don't have to wait for jobs to be submitted before adding a new job, you can add as many jobs as you'd like to the Sync Queue — they will submit themselves in the order you add them.

You can close the application once all queued jobs move to the Submitted section — processing continues on our servers. Completed syncs are available for download, typically within five minutes.

Editing Sync Timings (QC)

To review or adjust timings, click "Open Sync" and choose the .syncd file you want to edit. If the original video file moved, use "Remap Media Files" to update the location.

Warning

SyncDepo does not store your videos. If you move or delete a video file, you must remap it.

Sync editor
The sync editor with the active line highlighted.

Click any transcript line to jump to that timestamp in the video. Adjust timings with the controls below the video or via the right-click menu. As the video plays, the active line is highlighted.

Colored timestamps reflect confidence: green indicates highly confident, yellow is less certain, red means a timestamp could not be determined. Edited timestamps turn blue so you can track manual adjustments.

Manual mode

Manual Mode is the fastest way to QC your sync. Enter manual mode by pressing the m key or clicking the toggle. In manual mode, listen to the depo and press the . key at the end of each line to mark the start of the next line. Jump to the next problem line with n, mark a line as non-video with x, and use the and arrow keys to move between lines. Press Esc to exit manual mode.

Exporting Sync Files

When your sync is QC'd, click "Export" and choose the desired format. SyncDepo supports the following formats:
