Video Trimmer - Free Desktop App

Open your surveillance video in Diwadi, set the start and end times to the incident window using HH:MM:SS format, and trim. Fast mode cuts instantly without re-encoding, so even multi-hour CCTV files are trimmed in seconds.

With fast mode enabled (the default), Diwadi uses stream copy to cut at the nearest keyframe without re-encoding. This preserves the original quality and is nearly instant. Disable fast mode only if you need frame-accurate cuts, which requires re-encoding.

Yes. Fast mode preserves the original codec, resolution, and bitrate without re-encoding, so the trimmed segment is a byte-exact copy of the original stream. The file metadata is retained, and you can verify integrity by comparing codec details before and after.

Open the full recording in Diwadi, note the start and end timestamps of the relevant discussion, enter them in the trim fields, and export. The trimmed clip is small enough to share on Slack, Teams, or attach to a Jira ticket.

There is no hard limit. Diwadi runs locally on your desktop and processes files using your own hardware. Users regularly trim multi-hour recordings and files over 10 GB. Fast mode handles large files in seconds since it does not re-encode.

Absolutely. Trimming removes unwanted portions, which directly reduces file size. If the trimmed clip is still too large, you can follow up with Diwadi's video compression tool to shrink it further before uploading to government portals, email, or LMS platforms.

In fast mode (stream copy), the video stream metadata including codec, resolution, and frame rate is preserved exactly. Container-level metadata like creation date is carried over. For CCTV footage, the embedded timestamp overlay in the video frames remains intact since no re-encoding occurs.

Diwadi supports batch processing. You can queue multiple videos and set individual start and end times for each, then process them all together. This is useful when you need to extract segments from several surveillance cameras or meeting recordings.

Yes. Diwadi handles MOV files natively. Trim first to remove unwanted parts, then convert the trimmed clip to MP4 or any other format. Trimming first means the conversion step is faster because it processes less footage.

Open the dashcam file in Diwadi, find the incident timestamp, and set the trim window to capture the event plus a few seconds of context on either side. Fast mode preserves the original quality. The trimmed clip is ready to upload to your insurer's portal or email to your adjuster.
