VIOFO A329S 2CH – 7–12 Second Gaps Between Driving Recordings – Help Needed

[cartyre]

I have a VIOFO A329S 2CH (4K front + 2K rear) and I've noticed a concerning issue with the recordings while driving.

For some reason, when one clip ends and the next begins, the new clip sometimes includes around 7–12 seconds of footage from the end of the previous clip, so the two clips overlap. Other times, the transition is completely normal, with the next clip starting exactly where the previous clip finished.

More concerningly, however, I've found that some clips don't start until around 7–12 seconds AFTER the previous clip has ended, meaning there is potentially a 7–12 second period where no footage has been recorded at all.

For example:

Previous clip ends: 15:40:12
Next clip starts: 15:40:19
Difference: 7 seconds

This is obviously a major concern because something important could happen during those missing seconds, which defeats one of the main purposes of having a dash cam — continuous recording and reliable evidence if an incident occurs.

To clarify, all of these recordings are from normal driving mode, NOT parking mode.

Has anyone experienced this issue with the VIOFO A329S 2CH, and does anyone know what could be causing it or how I can resolve it? I'd really appreciate some advice as a matter of urgency, as I need to be confident that the camera isn't leaving gaps in the footage while I'm driving.

I format the SD card on the app and the camera itself every 3 days as it gets full quite quickly.

Also what is the time supposed to be? Does each clip suppose to contain the last 7 or 12 seconds of the previous clip?


Maybe its something to do with parking mode settings (attached) but dont see how it could be to be honest.

Can you upload a video of the “missing” footage?
If you don’t have a clock with seconds you can use a tablet, or computer monitor like this.
Also please post an APP screenshot of camera firmware version.

 

[cartyre]

Thanks Chuck. Do you mean to upload 2 clips where there is time missing between the clips?

 

[LeeShadow]

Please also let us know exactly what micro SD card you are using.

 

[cartyre]

I have a VIOFO PROFESSIONAL HIGH ENDURANCE MEMORY CARD
UHS-3 WITH ADAPTER - 256GB
£79.95
Quantity: 1

Do you mean to upload 2 clips where there is time missing between the clips?
Its not every single clip it happens, only say 1 in 10 clips theres issues with the loss of time.

On another note.

I have heard not to keep formatting it every three days simply because the card becomes full. That's what loop recording is designed to handle: once the card fills, the camera should automatically overwrite the oldest ordinary recordings. I shouldn't have to manually format it every time it fills? But I was told I have to do this as it will stop recording and beep continually, which has happened before until I formated the SD Card.

1.) Please post APP screenshot showing camera firmware.
2.) Please upload necessary video clips showing malfunction, so we can see what you’re seeing.
3.) We need to document the malfunction, so we can see what we fixed after we fix it.

A329S 2CH: 11.75 Hours
A329S 3CH: 10.75 Hours

Q: Hey Chuck just between me, and you;
Do you trust the camera to Loop Record without malfunction, or do you recommend I format the SD Card before it fills up? Come on man, tell me the truth.
A: The answer to this question is the same as why I don’t use parking mode for my personal application, and leave the camera running in normal recording mode when I go into the store for 1-3 hours.
1.) Based on my experience I do not trust any manufacturer’s Parking Mode to operate 100% reliable with zero malfunction.
2.) Based on my experience I do not trust any manufacturer's Loop Recording to operate 100% reliable with zero malfunction.
For my personal application I format dashcam SD Cards almost every time I go for a drive.

I would format the card with SDFormatter using the full format, not the quick format (this will take awhile for a 256GB card). After SDFormatter, place back in the camera and format again in the camera.

1.) Please post APP screenshot showing camera firmware.

I will do in the next couple of hours.


2.) Please upload necessary video clips showing malfunction, so we can see what you’re seeing.

I will try but not sure if files will be too large to upload

3.) We need to document the malfunction, so we can see what we fixed after we fix it.

I understand

4) does anyone know if clips are meant to follow on from the second the last one ended? Or contain a few seconds of the previous clip?

Upload the two videos to YouTube, and just post the links.

4) does anyone know if clips are meant to follow on from the second the last one ended?

Yes.

Hope these help. And the end of one clip and the start of another

We need to see the videos.
Please upload the videos to YouTube, and post the links.
Put a clock with seconds in front of the camera like this.

Ill try but sounds very complicated. Was hoping for some solutions I can try to resolve the issue.

Diagnosis comes before repair.
We need to duplicate the malfunction before it can be fixed.
Help me help you.

 

[cartyre]

I will do my best thanks. Im not very technical at all.

Your memory card could also be on the way out, and that is why it lag a little, maybe navigating bad sectors.
But a full format will check for stuff like that and alert about it.
Even the highest end big brand names can fail, back in the 64 Gb days i had 2 cards die on me really fast, the one i barely got to fill just 1 time.
Fortunately i got both replaced just fine, and one of them i still have and it work.

Why even today we must recommend to buy your memory cards where you get a chance of a replacement if they go sour, and not least also you avoid getting fake memory cards, CUZ those exist too.
but your Viofo card i am sure is genuine alright.

If you can not share videos using youtube ( if you are there there are privacy settings so only the people with the link can see them, or even tighter you can assign the people that can see them )
But if you are not on there, you can share the raw file segments via file share like googles drive or Microsofts similar setup, and there are also file share sites.

You might want to change to 1 minute segments, that way you at least have as little files as possible to upload / share.

I never format my memory card and my Viofo A329T has always just deleted older files when the memory card is full (which is all the time). I am using one of Viofo's recommended cards, a 256GB SanDisk Max Endurance and a 512GB Viofo Industrial. My 1-minute clips do not have any gaps or overlap between them.

VIOFO PROFESSIONAL HIGH ENDURANCE MEMORY CARD

OP - I don't think Viofo makes a "Professional High Endurance" -- Please confirm the card says "Viofo Industrial".

Your camera and memory card are not performing as expected. We need to examine your settings, card type, and videos to understand what is happening.

@cartyre

I noticed your cam is set to 60 Hz instead of 50 Hz. You may notice better image quality if you change that to 50Hz.

I suggest resetting the A329S to factory settings, then reflashing with the latest firmware. A329S Support

As previously suggested, do a Full format on the SD card.

Once you have done those two items, you'll be back to factory settings. Now record and see if the issue still occurs. I would set the dashcam time with your cellphone as well.

 

[kamkar]

50 or 60 Hz at least here in 50 Hz Denmark, some things will just flicker no matter what setting you have.

One other thing you'll want to let us know is the history of this SD card. Was it bought new with this system or was it previously used in anything else? How long has it been in service in total? Any kind of storage media has a finite lifespan, exactly how long that is depends on various factors like the type of device(s) it was used with, the type of condition(s) it was used in, how long it has been used for, how it was maintained, etc., so knowing this will better allow us to determine how "good" it still is.
