Usually this is something done in editing, but I don't know how much experience you have of that side of things. You will also need to know the frame rate you shot with in order to make the onscreen clock accurate.

I can see how it would be quite useful to have a function built into the camera which burns the frame number into the video as an option, but I suspect it's not high on the list of things to do, so if  I were you I'd learn how to do it in post.

For anyone in the UK looking for a RAM upgrade, MrMemory has the correct modules. I've upgraded both of my cameras with them and no problems at all.

You take the 4 bolts out from the back, carefully disconnect the 3 ribbon cables so you can separate the display from the body.

Then take 4 screws out securing the main PCB from the body.

Carefully disconnect the 2 (i think) ribbon cables linking it to the main sensor PCB and then you'll have full access to the memory module connectors on the other side of the main PCB.

It's not difficult as long as you're careful with the ribbon cables and their connectors. If you are unsure how the ribbon cable connectors work, ask here first or do some googling.

This is what David has said before:

"while opening the camera doesn't void the warranty, damage due to improper user repairs isn't covered."

So, upgrading the RAM won't void anything but you need to be sure you are using the correct module(s) and you don't damage anything.

As long as you've installed Python as David details, the easiest way is to create a folder on your PC, copy the pyraw2dng.py file and your .raw file from the Chronos into it, then create a batch file to run it.

I've attached an example .bat file you can use.

So, in the folder you should have test.bat, test.raw and pyraw2dng.py. Edit your .bat file with a text editor to get the resolution and raw filename correct then just double click the test.bat file and it should run.

Something which might help those of you worried about 'fat finger' syndrome...

(This also helps when outside in the cold and wearing gloves).

I had one of these I got originally to use on an old smartphone which had a terrible touch screen. I've now got a better phone, so this was lying around and I thought I'd try it with the Chronos.

It works a treat, so much so that I've tethered it to the side of my Chronos so it's always to hand.

I've now managed to get over the 4GB limit using the method Dan D found, but on a Windows 10 PC.

If you want to save RAW files larger than 4GB, here's what you do:

Download and install the free utilities 'MiniTool Partition Wizard Free' and 'Ext2Fsd'.
Format a USB stick or SD card as EXT3 using MiniTool Partition Wizard. I've used a 128GB USB stick successfully.
Plug it into the Chronos and select it in the Save Location dropdown. If it doesn't appear, something's gone wrong with the formatting of the drive.
Record and save to the EXT3 drive (when you get the 4GB warning message just tell it to save anyway.)
When finished saving, plug the card/stick into your PC and use Ext2Fsd to copy the contents to an NTFS drive. 

I just did this with a 21GB recording. It took 47 minutes to save to the stick, but we know it's going to be slow at the moment.
The main thing is it worked I don't have the 4GB limit any more.

I think I better free up some hard drive space now

I have made some raw recordings at different resolutions but didn't make a note of the settings.

How can I find out what length and width to put into the script just from the RAW file?

You'll need to use trial and error for now, unfortunately. Try different values for horizontal resolution, leaving the vertical resolution set to 1024, until you get an image that looks clear. Once you have horizontal resolution set correctly, it's much easier to figure out the proper vertical resolution just by looking at the output image.

This conversion tool is very much a stopgap measure until we have this functionality built into the camera.

Ok I guessed the right number, so I can process those raw files now! Thanks.

Absolutely agree with all of that. RAW is the only way to go IMO but to make it usable we need:

Remove 4GB filesize limit
Speed up write to the SD/USB
Include metadata somehow with each recording

I'm happy to do a lot of post processing as that can be largely automated and I am about to order a nice new i7 8700-based PC
RAW+jpg would be nice, but not if it impacts on save time too much.

Of course, if all of this can be achieved once we have tethered ethernet working, that will probably be the better way to go anyway.

I still need some way to find out what resolution is of some of the raw files I recorded yesterday...
