How did the 64GB storage look on other users/owners that got InfiRay stand alone-models, like any of the FLIP series or the monocular scope models, when you attached it to fx PC to save the content.?
My unit saves a lot of data into a precompiler format [.pre) on pretty much all the 4 root folder-pibelines. (tens of GB)
and I guess its unprocessed RAW precompiler content.?
Asked [Chat] if it was a precompiler-revenue of perhaps the chunked filestructure that I encounter on these models from InfiRay...
It's something you often see on fx actions cams, dash cams etc. to prevent corruption or simply to ease file management purposes, where each file, video, picture etc - are the the exact same size, no matter if its a 3 sec. video or 3-minute video.
but it doesn't seem so' that these precompiled files are related to that chunked file-structure approach..

No, a .pre file format is not specifically required for the approach of saving video or image data in equal-sized chunks. The .pre format you're referring to is likely specific to the thermal camera. (mentioned previously*)
It’s a proprietary format that stores thermal data, potentially including temperature readings, metadata, and other information, rather than standard video or image content.
For the type of chunked video saving approach you're asking about, it typically uses standard video file formats like:
MP4 (most common for video),
MOV, or
AVI, among others.
These formats use standard compression codecs such as H.264 or H.265 for video and AAC or PCM for audio. The video is split into multiple files, usually with a consistent size or duration (e.g., 5-minute chunks or 1 GB per chunk), but the format of the file itself remains standard, allowing for easy playback and editing.
How Chunked Video Files Are Typically Managed:
File System Limitations: The chunked video approach (such as fixed-size video segments) is often used because of limitations in the file system, especially with FAT32 (which has a 4 GB file size limit) or to make file management easier. For example, a camera could divide a long recording into multiple smaller files (e.g., video001.mp4, video002.mp4, etc.) with each file being 1 GB or 5 minutes long, making it easier to store, transfer, or back up.
Standard Formats (MP4, MOV, AVI): The files within these chunks would still be encoded in common video formats, and each chunk would just be a separate video file. This is different from the .pre format, which is more focused on thermal data, and not typically used for standard video content.
You do not need a .pre format for chunking video files. The .pre format is specific to storing thermal or radiometric data, while chunked video recording uses standard formats like MP4, MOV, or AVI. If you’re working with typical video recording (like for security cameras, dash cams, or action cameras), those systems would use these common video formats and simply divide the footage into chunks of consistent size or duration for easier file management.
Open or analyze .pre files.

I currently cannot directly analyze files like .pre files, but I can provide guidance on how you might handle or open them based on common use cases for such file formats. .pre files are often used for thermal camera data, such as those from infrared (IR) cameras, and they may contain both thermal image data and temperature measurements.
Common Approaches to Open and Analyze .pre Files:
Manufacturer-Specific Software:
FLIR Tools or similar software: Many thermal cameras (including some models from InfiRay) often use proprietary file formats, such as .pre, which can only be opened and analyzed using the manufacturer's software. These software tools can:
Open the .pre file.
Display the thermal image.
Provide access to radiometric data (temperature values).
Allow for post-processing, measurements, and analysis of the thermal data.
If your thermal camera is from a specific manufacturer, it’s best to check their website or documentation for the official software to open and analyze .pre files. You can also contact their support if you can't find the right tool.
File Format Documentation:
Documentation: Sometimes, the .pre file format is mentioned in the camera's user manual or technical documentation. The document may explain how the data is stored and offer specific ways to access it. Some companies provide open access to their file formats or even provide SDKs (Software Development Kits) to interact with these files programmatically.
Generic Thermal File Viewers:
Thermal Image Viewers: While most proprietary formats like .pre are specific to certain manufacturers, some third-party thermal image viewers or analysis tools may support a range of formats. If you have access to the thermal image content but are unsure about the file extension, you might try opening the file with some third-party tools or check whether the file format is convertible to a more common one (like .jpg, .png, or .tiff).
Programming Approaches:
Use of APIs or SDKs: If you're comfortable with programming, many thermal camera manufacturers offer SDKs (Software Development Kits) or APIs that allow you to access and analyze thermal data from proprietary files (including .pre). You can write scripts in languages like Python or C++ to open the files and extract temperature data or visualize the thermal image.
For example:
Python libraries like OpenCV for image processing could potentially handle the visual content of a thermal image if converted to a compatible format.
Some thermal camera manufacturers offer APIs specifically for working with their data files, allowing you to access and analyze temperature values stored within.
Summary of Steps to Open .pre Files:
Check the Camera Manufacturer’s Software: Look for any software specifically designed by the camera manufacturer, like FLIR Tools (for FLIR cameras) or a similar software package from the camera brand you're using.
Contact Manufacturer Support: If you can't find a way to open .pre files, reaching out to the manufacturer's support might help, as they should be able to provide guidance on how to open and analyze these files.
Try Conversion Tools or SDKs: If you prefer a more programmatic approach, look for SDKs or APIs from the manufacturer to process the data or use generic image viewers that support thermal data.
If you provide more information about the camera model or manufacturer associated with the .pre file, I can try to offer more specific tools or software suggestions for you.
Anybody came across .pre files when working with some of the other thermal camera manufacturers and their PC or analyze software
fx some of the software from Forward Looking InfraRed/Flir, Fluke, Sense Batch, Thermoviewer etc.
Tried Thermoviewer, but it only supports their [thr, thc, them, tmc, tfc, cfc]..
