PDF Files

Jan 25, 2026 Last reply: 5 months ago 10 Replies

I down loaded an 8 page pdf from Nextbase telling me how to download files from my dashcam.



Very helpful but following modern trends it was white on black and goodness knows what that would do to my printer ink if I printed it. So right click, select "Nuance's Convert to Word" and it did perfectly, except it's the Greek version.



At my age it is very easy to believe I have finally lost it so I tried again and it did it again. That seems to imply that a pdf can contain documents of several languages but Foxit Reader (my my default pdf viewer) is clever enough to show the version pertaining to the OS language. Is that possible?



In addition a warning. Some time after down loading it I had an email from Nextbase asking me to participate in a survey on its customer service. I thought I would take part and tell it that producing white on black documents is moronic. I then twigged that I hadn't given an email address to download it and on closer inspection it was from "tidioreply.com" so presumably spam.



Is this an astonishing coincidence or has some bot put my email address together with the fact I have been asking questions about Nextbase on Usenet?


Use SamatraPDF, press 'i' to invert colours, I assume that option applies to printing as well as viewing ...

Thanks Andy, brilliant for viewing but sadly not for printing when it reverts.

Anyhow I managed to connect!

Forget infotainment and references in the instructions to a 'phone, you just need a tablet with Bluetooth and WiFi. Did a firmware update then connected with the app. Searched through carefully and found what I thought was my first journey. Turned out to be the hand over session when the sales lady went through all the controls with me, excellent half hour video of the dealer's courtyard!

I am going to find instructions on how to extract the SDC card...

I now have LOTS of mp4 files. They seem to end FH.mp4, FL.mp4, RH.mp4 and LH.mp4, Front/Rear Low/High I think. Poor little dashcam must be busy saving (or converting) 4 different streams.

Anybody recommend an app to join them into 1 x mp4? MP4Joiner fails, LosslessCut-win-x64 doesn't recognise the format and although vlc can join them the online instructions are vague and it re-renders them so I will lose some quality.

Ah. Handbrake maybe or OpenShot? - and there are more out there

Are you talking about putting the FH frame above the FL frame ? Changing the dimension of the image ?

Or just sequentially joining all those together.

There is GSpot and MediaInfo for video identification, and I don't know if any additional ones have been written. GSpot is ancient and not good for new content.

While you can run ffprobe to identify the streams inside a video, I don't know if that allows any fancy identifications of "high profile" or the like.

Linux has the file command. This labeling isn't particularly helpful.

To do it with FFMPEG, Googling them is more likely to work, than the manual :-)

It's probably faster to just ZIP them up (in Store Mode). That's lossless :-)

There aren't that many, I have tried the 2 highly recommended one with no success so far, I was hoping for a personal recommendation :-)

It's high/low resolution, it seems to save both.

I am a Windows user, I do revert to the command line occasionally but don't enjoy it, I just want to chuck a heap of files at something and have it join them together while maintaining quality.

OK, working on a front end :-)

OK done and works, will pretty it up tomorrow :-)
