This is a neat feature however a few seconds are lost between the clips. With MagicLantern I'm able to automatically start recording once the 4GB file size limit stops the recording. I reformatted to exFAT and while the camera accepted it, I could not record a video bigger than 4GB. Anyone know of a fix for this on the SX20? For the PowerShot cameras, the file size limit is likely much lower. Breaking the 30 minute video recording limit without breaking the bank by Leon Watkins (Website | Facebook): Summary: I’ve built a portable, lightweight rig using a gaming recording device to record a clean HMDI feed straight from the camera for continuous takes of over 30 minutes. Also according to these sources, the limit for both cameras is 4gb. Hi Folks. But the 4GB file size limit on SDHC cards is really annoying. One of the major frustrations I’ve had over the years is […] I know that the FAT file system only allows for 4GB, less than 30 minutes on HD. The camera is inaccessible for manually stopping and restarting the recording. It sounds like actual video cameras will not stop recording but will break the file up into 4GB chunks while its still recording. Note there is no 4GB file limit when using exFAT formatted SDXC cards. So I reformatted the card (San Disk 80 MB/s - 16GB SDHC) to NFTS but the camera did not take it. Even though other regions may not apply similar tax rules, it is easier for camera manufacturers to apply the 29min59sec limit to cameras for all territories. The Canon T3i (and it seems like most cameras that can take video) has a 4gb file limit because it is using the FAT32 file system (it also stops at 30 minutes, whichever comes first). The maximum file size on FAT32 is 4GB-1. Is this a hard limit? Especially the huge zoom and HD video recording. Visit http://thepodcastersstudio.com/gear to see a list of all the gear used in this video. I believe the limit is due to the file size, not the actual recording length.This forum thread seems to confirm this for the T2i/500D, and Wikipedia agrees for the 5D mkII. I want to record longer videos on my camera. ? Thanks Mike Hi HannahIvy, You could try formatting your 64GB Card to EXFat using your computer,(Either Window's Vista or later and/or MAC OS X after Snow Leopard(10.6.5)) then putting it in your camera and see if the camera can write to it without any problems, I believe Canons can see EXFat Cards, this should get round the 12 minute time limit and give you the full 29 minutes and 59secs. You have to manually restart the video. Think a bout it, a TV show is, what, 20 minutes (30 min - commercials, intro, ending, etc). Not really an issue, I have never seen a single segment of video last more than a couple minutes in most movies/tv shows. Is there a way to increase the file size limit? Can this be fixed through changing the format to exFat or NTFS? If you could shoot for longer the camera would be reclassified as a video camera and subject to higher taxes. I'm not familiar with the original 7D (I have a 7D II), but unless the firmware is programmed to record to multiple files, switching to a new file automatically when you hit the 4GB-1 limit, that's going to be your limit. In the new Canon EOS-1D X, the 4GB limit per clip remains, but when shooting, new files are created automatically once the 4GB limit is reached, without losing frames, and the files can be edited together seamlessly. Newer cameras overcome this limitation by seemlessly starting a new file, but the 600D doesn't do that. I've heard some say it's a heat issue, but after the camera stops, I can immediately restart it … I’m trying to shoot a video longer than 4Gb and have run into problem that the 7D MKI does not just continue with a new file like later cameras. As Josh said, the cards are formated in FAT32 which ash a max file size of 4GB. Due to the file system (FAT32) of the SD card no file can be larger than 4 gigs (they breifly mention it at the top of the page), so the camera stops once it hits that limit. We just got a Canon SX20 and absolutely love it. The card format set by the Canon T3i is FAT32.
