R5c - Cant find big recorded video through USB connection

colwer — Tue, 26 Dec 2023 06:49:33 GMT

Hi folks. I recorded few super big videos with my r5c on a CFb card. And with proper card reader I can see and download the video files.

However, when directly connected to my windows PC. I can see both pictures and <4GB videos. But the bigger videos seems to be nowhere found. Any help will be appreciated.

For technical reason, files sizes are limited to. 4GB in size. If you record “long video” clumps, then you will never find files larger than 4GB. Instead, you will likely find a group of associated files that are limited to 4GB in size.

During recording, some camera screates multiple files. Other camers may stop recording when they hit the 4GB files limit, which requires you to restart recording.

During playback, one 4GB file is opened for reading, while the next file in the sequence if on standby until it is needed. Playback experience lends the appearance that you are watching a single file.

It seems that the R5C's USB -- only the USB -- is somewhat crippled; it only allows for transfer of non-RAW, or possibly just small, files. I think this is because it uses PTP, as opposed to MTP, which is a really bad idea.

The solutionis to use a card reader, as you are doing. I've been doing that since I got my R5C, and I've never seen a problem.

You can of course record any file size you want -- well, technically, exFAT limits you to 128 PETA bytes. I've never seen a problem, and with my R5C I routinely record and use files well into the tens of gigabytes. There is effectively no file sze limit, and files do not get split. Modern cameras, with exFAT, do not need to do that.

Your points are relevant to any devices using FAT32 file systems; older cameras, or any other devices. For modern exFAT-based devices, the max file size is 120 petabytes, and no file splitting is needed.

Thanks AL.

I guess I have to stick with my CFb reader then 😞

This problem bothers me since my M62. **bleep** I cant understand why Canon cant make a related firmware update about it.
