Video Exhibit Too Large for Court E-Filing?
Compress Video Evidence Without Compromising Quality
Court e-filing systems have strict file size limits. A single surveillance clip or phone video can exceed portal limits by 10-100x. Compress and convert offline to preserve evidence integrity — files never touch a third-party server.
Court E-Filing System Size Limits

Common Video Evidence Scenarios
Surveillance Video from Security Camera
Security camera footage is typically recorded in AVI or MKV format at 1-10 GB. These proprietary formats are often incompatible with court systems and far exceed file size limits.
Convert to MP4 (H.264) and compress to under 50 MB. Diwadi preserves visual clarity of faces, license plates, and timestamps. Typical result: 2 GB AVI becomes 30-45 MB MP4.
Compress Surveillance VideoPhone Video Recording of Incident
iPhone and Android videos record in MOV or MP4 at 4K resolution, producing hundreds of megabytes for just a few minutes of footage. A 3-minute 4K iPhone video is typically 500-800 MB.
Compress and downscale to 1080p while maintaining all visual detail. Timestamps and audio are preserved. Typical result: 600 MB iPhone MOV becomes 25-40 MB MP4.
Compress Phone VideoDashcam Footage
Dashcams record continuously, producing hours of footage in proprietary formats. You need to extract only the relevant 30-second to 5-minute segment from a multi-hour recording.
Trim to the relevant segment, then compress. Diwadi lets you select the exact start and end points. Typical result: 4-hour recording trimmed and compressed to 20-40 MB.
Trim and Compress Dashcam VideoBody Camera or Wearable Footage
Body camera and wearable footage is often recorded in proprietary formats (e.g., AXON, VIEVU) that courts cannot open. Files are also typically very large due to continuous recording.
Convert proprietary formats to standard MP4 and compress. All visual and audio evidence is preserved. Typical result: 1 GB body camera file becomes 35-50 MB MP4.
Convert Body Camera VideoScreen Recording of Digital Evidence
Screen recordings of browser activity, chat conversations, app interactions, or financial transactions can be 200-500 MB for just a few minutes due to high resolution and lossless encoding.
Compress screen recordings while keeping text, timestamps, and UI elements sharp and readable. Typical result: 300 MB screen recording becomes 15-30 MB MP4.
Compress Screen RecordingWhy Offline Processing Matters for Evidence
Video evidence requires careful handling to maintain its evidentiary value. How you compress and convert video can affect its admissibility in court.
Chain of Custody
When video evidence is uploaded to an online compression service, it passes through third-party servers. This breaks the chain of custody and can be challenged by opposing counsel. Offline processing with Diwadi means the video file never leaves your device.
Metadata Preservation
Video files contain metadata — timestamps, GPS coordinates, camera model, recording settings — that can be legally relevant. Some online tools strip this metadata during processing. Diwadi preserves original metadata where technically possible.
Preserve the Original File
Always keep the original, uncompressed video file alongside the compressed version submitted to the court. The original may be requested for verification. Diwadi saves compressed files as new copies — your original is never modified.
Document Your Compression Settings
Record the compression settings used (codec, resolution, bitrate) for the court record. If challenged, you can demonstrate exactly how the file was processed and that no content was altered. Diwadi shows compression details in the output summary.
No Third-Party Server Processing
Free online video compressors process files on remote servers, potentially in foreign jurisdictions. This raises questions about who accessed the evidence and whether it was modified. Desktop processing eliminates these concerns entirely.
How to Compress Video Evidence with Diwadi
Download and Open Diwadi
Install Diwadi on your Mac or Windows computer. No account needed, no internet required for video compression. Your evidence stays on your device.
Import Your Video Evidence
Drag and drop your video file — surveillance footage, phone video, dashcam clip, or screen recording. Diwadi supports AVI, MOV, MKV, MP4, WMV, FLV, and most other video formats.
Compress and Convert to MP4
Select your target file size based on your court's e-filing limit. Diwadi will compress and convert to MP4 (H.264), the most widely accepted court format. Preview to confirm faces, text, and details remain clear.
Upload to Court E-Filing System
Your compressed video is saved locally as a new file — the original is untouched. Upload the compressed version to CM/ECF or your court's e-filing portal. Keep both the original and compressed files in your case records.
Why Process Video Evidence Offline?
Maintain Chain of Custody
Uploading evidence to online compressors breaks chain of custody. Opposing counsel can challenge evidence that was processed on third-party servers. Diwadi processes everything locally on your device.
Preserve Evidence Metadata
Video metadata (timestamps, GPS, camera info) can be legally significant. Online tools often strip metadata during processing. Diwadi preserves metadata where technically possible during compression.
No Third-Party Server Access
Free online compressors process files on remote servers, potentially in jurisdictions with different data protection laws. Your evidence could be cached, logged, or accessed by unknown parties.
No Watermarks or Branding
Many free online video compressors add watermarks to processed files. Watermarked evidence is unprofessional and may be questioned by the court. Diwadi never adds watermarks.
Works Without Internet
Prepare video exhibits from anywhere — your office, the courtroom, or while traveling. No internet connection needed for compression, so you can meet filing deadlines even with limited connectivity.
Common Mistakes When Compressing Video Evidence
Compressing until faces and details are unrecognizable
Aggressive compression can blur faces, license plates, timestamps, and other critical details. Always preview the compressed video and ensure all evidentiary details remain clearly visible. If details are blurred, use a higher quality setting even if the file is larger.
Stripping metadata that could be relevant
Video metadata (recording date/time, GPS location, camera model, duration) can corroborate testimony or establish facts. Some tools strip metadata during conversion. Verify metadata is preserved or document it separately before compression.
Not preserving the original uncompressed file
The original video file should always be preserved as part of the case record. If the court or opposing counsel requests the uncompressed original, you must be able to produce it. Never overwrite or delete the source file.
Missing filing deadlines because video won't upload
Discovering at the last minute that a video exceeds the e-filing size limit can cause missed deadlines. Compress and test-upload video exhibits well before the filing deadline. Keep pre-compressed versions ready.
Using online tools that add watermarks to evidence
Free online video compressors often add watermarks or branding to output files. Submitting watermarked evidence to a court looks unprofessional and may raise questions about the file's integrity. Use a desktop tool that produces clean output.

Frequently Asked Questions
What is the CM/ECF file size limit for video exhibits?
The federal CM/ECF system has a general limit of 50 MB per filing, but individual districts may set lower limits for exhibits. Some districts allow up to 50 MB per attachment, while others cap individual files at 25-35 MB. Check your specific district's local rules or contact the clerk's office.
What video format do courts accept?
MP4 (H.264 codec) is the most widely accepted video format across US federal courts, state courts, and international court systems. Some courts also accept AVI, MOV, and WMV. When in doubt, convert to MP4 — it offers the best compatibility and compression ratio.
Will compressing video evidence affect its admissibility?
Compression itself does not automatically make video inadmissible. However, if compression degrades the video to the point where critical details are no longer visible, or if the chain of custody is broken by using third-party online services, admissibility could be challenged. Use reasonable compression settings, preserve the original, and process offline.
How do I convert surveillance footage for court filing?
Security camera systems often record in proprietary formats (AVI, MKV) that courts cannot open. Use Diwadi to convert the footage to MP4 format and compress it to meet your court's size limit. The conversion happens entirely on your computer, preserving chain of custody.
Should I preserve the original video file?
Absolutely. Always keep the original, uncompressed video file as part of your case record. The court or opposing counsel may request the original for verification. Diwadi saves compressed files as new copies and never modifies your original.
How do I compress a phone video for e-filing?
Phone videos (iPhone MOV, Android MP4) are often recorded in 4K, producing very large files. Import the video into Diwadi, set your target size based on the court's limit (e.g., 50 MB for CM/ECF), and compress. The app will downscale resolution and adjust bitrate while keeping the video clear.
Can I submit video evidence via email to the court?
Most courts do not accept evidence via email. Video exhibits should be submitted through the court's official e-filing system (CM/ECF for federal courts, or the state equivalent). Some courts accept physical media (USB drives, CDs) for large video files. Check your court's local rules.
What resolution is acceptable for court video exhibits?
Most courts do not specify a minimum resolution, but 720p (1280x720) is generally considered acceptable for evidentiary purposes. 1080p is preferred if the file size allows. The key requirement is that relevant details — faces, license plates, timestamps, text — must be clearly visible.
How do I extract a relevant clip from a longer recording?
Use Diwadi's trim feature to select the exact start and end points of the relevant segment. This is especially useful for dashcam or surveillance footage where only a few minutes out of hours of recording are relevant. Trimming also significantly reduces file size before compression.
Is it safe to use online video compressors for legal evidence?
Online compressors require uploading your evidence to third-party servers, which breaks chain of custody and creates potential security and privacy concerns. Opposing counsel could challenge evidence processed through unknown servers. For legal evidence, always use a desktop tool like Diwadi that processes files entirely on your device.
