How to find the right dashcam clip for your insurance claim

Something went wrong, and now you're staring at a folder full of files named CH01_20241103_142301.mp4 trying to figure out which one shows the moment someone ran into your car. Finding the right dashcam clip for your insurance claim is one of those tasks that sounds simple until you're actually doing it under stress, with an adjuster waiting for your evidence.

This guide walks you through the whole process: from pulling the footage off your card to handing over a clean clip that holds up.

Why finding dashcam footage is harder than it should be

Dashcams don't save your footage the way a phone saves a photo. They record in short loops, usually one to five minutes per file, and they overwrite old footage automatically when the card fills up. A 128GB card can hold 20 to 40 hours of footage. That's somewhere between 400 and 2,400 individual files.

File names are either timestamps (if you have a decent camera) or sequential numbers like REC_00847. TS (if you don't). Some cameras use proprietary formats. Some split front and rear footage into separate folders. Some lock "incident" clips when the G-sensor triggers, some don't.

The result: after an accident, you have hundreds of short clips and one specific three-minute window you actually need. You might know roughly what time it happened. You might not. And the clock is running, because loop recording will eventually overwrite that footage if you don't act.

Pull your SD card as soon as possible after any incident. Don't leave it in the camera. Loop recording doesn't care about your insurance claim.

How to find the right dashcam clip for your insurance claim: start here

Before you do anything else, make a copy. Pull the SD card, plug it into your computer, and copy the entire contents to a folder on your hard drive or an external drive. This takes five minutes and protects you from two things: accidental overwriting, and a card that decides to fail at exactly the wrong moment.

Once you've got a backup, you can work from the copy without touching the original.

Then figure out what you're actually looking for:

• What time did the incident happen? Even an approximate window (between 2:15 and 2:45pm) helps enormously.
• What date? Double-check this. Stress scrambles memory.
• Which camera? Front, rear, or interior? Most incidents will be front footage, but rear cameras catch rear-end collisions clearly.
• Any distinguishing details? Weather, location, other vehicles, what happened immediately before or after.

Write these down before you start digging through files. It keeps you focused.

Reading dashcam file names and folder structures

Most dashcam file names follow a pattern. Once you recognize it, you can navigate hundreds of files quickly.

Common patterns:

If your camera puts timestamps in the file names, this is straightforward. Sort the folder by name, find the time range you need, and check two or three files either side of it. Dashcam clocks drift, and sometimes they're set wrong in the first place.

If you're working with sequential numbers and no timestamps, check the file's metadata. Right-click, properties, look at "date modified." That's usually close to when the file was created, though it'll update if you've opened the file. Work from your backup copy and avoid opening files you don't need to.

What to do when the G-sensor triggered

Many dashcams have an impact sensor that locks a clip when it detects a sudden jolt. These files often go into a separate folder called EVENT, GSENSOR, or LOCKED. Check this folder first. If your camera triggered on impact, the clip you need might already be separated from the rest.

If the locked folder is empty, either the impact wasn't sharp enough to trigger it, or the camera wasn't running at the moment (which happens if you turn the car off before the incident, or if power was cut). In that case, you're back to searching by time.

How to find the right dashcam clip for your insurance claim using video search

If you have a large backup and you're not sure of the exact time, manual scrubbing is slow and unreliable. Watching 30 seconds of each clip across 400 files would take hours, and you'd probably miss the right one at 4x speed anyway.

Rootl is a desktop app that lets you search your video files using plain language. You point it at your dashcam backup folder, describe what you're looking for ("car running a red light and hitting mine from the left"), and it finds the relevant moment across all your clips.

Rootl searches through your dashcam footage without uploading anything. Everything stays on your machine, which matters when you're dealing with potential legal and insurance evidence.

It handles the common dashcam formats including MP4, AVI, and TS files from loop recording systems. You don't need to convert anything first. Point it at the folder, let it index, then search.

This approach works especially well when:

• You have a large card with many hours of footage
• You're not sure of the exact time
• You want to find all relevant clips, not just one (there might be footage from minutes before the incident that shows the other driver's behavior)
• You have front and rear footage in separate folders and want to search both at once

See how Rootl handles dashcam footage if you want to understand what it actually does before downloading.

Checking the clip before you send it

Once you've found the file you think is the right one, watch the whole thing. Don't skip through it. You're checking for a few things:

Does it show the incident? The actual moment needs to be in the clip, not cut off at the end of a segment. If the incident happened at the very end of a loop, check the next file too. The impact might be in one file and the aftermath in the next.

Is the timestamp visible? Many dashcams burn a timestamp into the video itself. If yours does, check that it looks correct. A timestamp that's obviously wrong (because the camera clock was never set) is something you'll need to explain to your insurer. It doesn't invalidate the footage, but it's worth addressing upfront.

Is the footage clear enough? Night footage, heavy rain, and direct sun glare can all reduce visibility. Watch the clip honestly. If you can make out what happened, your insurer probably can too. If it's too dark or blurry to see the relevant detail, say so. Partial evidence is still evidence.

Is there audio? Some cameras record audio, some don't. If yours does, check whether the audio is useful or whether it's just road noise. Either way, leave the audio in. Don't edit it out.

Making a copy for submission

Don't hand over your original SD card or your only backup. Make a copy of the specific clip you're submitting, and keep the originals somewhere safe.

If the incident spans more than one file (because it happened at a segment boundary), copy both files. Name them clearly: incident_clip1_20241103_1423.mp4 and incident_clip2_20241103_1425.mp4 is easier for an adjuster to work with than REC_00847. MP4.

Don't re-encode or edit the video. If you need to trim a long clip to just the relevant section, use a tool like VLC's scene export or FFmpeg to cut without re-encoding. Re-encoding changes the file and can raise questions about whether it was altered.

# Cut a clip from 1:30 to 2:45 without re-encoding
ffmpeg -i input.mp4 -ss 00:01:30 -to 00:02:45 -c copy output.mp4

Keep a log of everything you do with the footage: when you copied it, what you submitted, what tools you used. If the claim becomes a dispute, this documentation matters.

What insurance companies actually need from dashcam footage

Insurance adjusters see a lot of dashcam clips. Footage that's well-organized and clearly labeled moves faster through the process. Industry research shows claims with video evidence resolve 30 to 50% faster than those without.

When you submit footage:

• Include the original file, not a screen recording of you playing it on your laptop
• Note the camera brand and model so they understand the file format
• Note whether the timestamp is accurate (and if not, what the correct time was)
• Include front and rear footage if both are relevant
• If you have GPS data embedded in the footage, mention it. Some cameras record speed and location as metadata.

Most insurance companies accept MP4 and AVI without any conversion needed. TS files (common from Thinkware and Vantrue cameras, among others) may need to be converted first. Again, FFmpeg handles this cleanly without re-encoding.

# Convert TS to MP4 without re-encoding
ffmpeg -i input. TS -c copy output.mp4

What happens if you can't find the clip

Sometimes the footage is gone. Loop recording overwrote it before you pulled the card. The camera wasn't on. The file is corrupted.

If the footage is overwritten, recovery software sometimes helps. Recuva is free and works well on FAT32-formatted SD cards, which is most dashcam cards. It's not guaranteed, but if you haven't written new data to the card since the incident, recovery is possible.

If the camera wasn't on, or the clip is genuinely unrecoverable, document that too. Tell your insurer what camera you have, that you attempted to retrieve the footage, and that it wasn't available. This is better than silence.

After the claim: getting organized for next time

Once this is resolved, take 30 minutes to set up a better system.

Check your dashcam's clock. Set it to the correct time and make a note to check it every time you change the clocks (or just annually). A correct timestamp makes everything easier if you ever need the footage again.

Consider your card size and retention window. A 128GB card with a high-bitrate camera might only keep seven to 10 days of footage. If that's not long enough for your situation, a larger card or a camera with longer retention matters.

Back up footage regularly if your dashcam records anything important. Some cameras support automatic WiFi backup to a local folder. If yours does, turn it on. Rootl can index that folder and let you search everything with plain language, so it doesn't just help in emergencies. It makes the whole footage library searchable.

Frequently asked questions

How do I find a specific clip on my dashcam for an insurance claim?

Start by copying your entire SD card to your computer before doing anything else. Then sort files by timestamp or check the metadata if your camera uses sequential numbering. If you have a large archive or aren't sure of the exact time, a tool like Rootl can search through hundreds of clips using a plain-language description of what you're looking for.

How long does dashcam footage last before it gets overwritten?

It depends on your card size and camera settings. A 128GB card typically holds between 20 and 40 hours of footage before loop recording begins overwriting the oldest files. Pull your card as soon as possible after an incident. Don't leave it recording in the car.

Can I use dashcam footage as evidence for an insurance claim?

Yes. Most insurance companies accept dashcam footage, and claims with video evidence tend to resolve 30 to 50% faster than those without. Submit the original file rather than a screen recording, and note whether the camera's timestamp is accurate.

What format do dashcam clips need to be in for insurance?

MP4 and AVI are universally accepted. TS files, which are common with some dashcam brands, may need to be converted. You can do this with FFmpeg without re-encoding, which preserves the original quality and avoids any suggestion of alteration.

What if the dashcam footage I need has already been overwritten?

Try a free recovery tool like Recuva on the original SD card before writing anything new to it. Recovery is possible on FAT32 cards if no new footage has been recorded over the deleted files. If recovery fails, document the attempt and let your insurer know you tried.

Can Rootl search through dashcam footage automatically?

Yes. You point Rootl at your dashcam backup folder, it indexes the contents locally, and then you can search in plain language: something like "someone merging into my lane" or "rear-end impact at an intersection." Everything runs on your machine without any uploads. It handles MP4, AVI, and TS files from common dashcam systems.
