Could someone please verify that with an SDXC card (please name the card + specs) the 25 min can be recorded in one single movie?

The German site states that 64 GB is the max size for SDXC cards that can be taken by your camera. Neue Firmware für PENTAX Kameras - Nachrichten - Division Imaging Systems - PENTAX Europe Imaging Systems
That might be but formally its wrong, because this info was mentioned for the Pentax 645 D! So maybe once we can use SDXC cards with 2 TB.

Code:
Firmware 1.01 für die 645 D:
  • Neu mit dieser Aktualisierung ist die Kompatibilität mit SDXC Speicherkarten.
    Dadurch kann die 645D jetzt Speicherkarten bis zu 64 GB verarbeiten.

I own a SanDisk 64GB SDXC card, and 25 min is the limit. You can verify yourself even without an SDXC. Set the movie quality to VGA/25 and 1*, which is the lowest quality possible, and try with your 8 GB SDHC cards. You'll see that 25 minutes is the maximum time possible, even if the card can hold more than 25 minutes.

Sorry as I red my post again I didn´t mention that I was focusing on FullHD *** Mode. With this question I was focusing more on the 4 GB filesize limit of the camera itself (Pentax specs!). Since they allow now SDXC cards the 4 GB filesize limit should be gone. If this restriction isn´t somehow made by the camerasystem - which I don´t know. So can you record 25 min in FullHD *** Mode with this SDXC card? I would buy then an SDXC card. Am I correct you have the Sandisk Ultra SDXC 64 GB class 4 card with "15 MB/s"?

Thanks

O wow you have the SDXC card. SanDisc?

Maybe you coult run the writespeed test:

https://www.pentaxforums.com/forums/pentax-k-5-forum/128924-writespeed-secure...ml#post1353362

So fill the buffer with large hi-iso files and time them to see what is real-live writespeed in the K-5. I know that max 15mb/s is stated, but is it true.

No !
One more time, i repeat :
Video file size is limited by the file system ! All cameras use FAT32 file system, there is a 4Gb file limitation with it.
You can have a 128 Gb SDXC card, if you use FAT32 with it, you wil have a 4GB file limit.

However the thing that is possible to give the liveview output as video transmitted. No recording, just HDMI output.
That's exactly what I was after. Has anybody tested this, with an external power unit?

No idea how long you can run it before sensor gets heated.
Instantly, I am sure. If you mean OVERheated, that is something else But it would be a good test.

I have done 16 mins of video recording, starting with a pre-warmed camera, and didn't get any sensor spots forming.

Well basicly it is what I use sometimes for video. A fieldmonitor.

There is the problem of HDMI output with videomode. It is in VGA. The problem you can see in this video is to overcome and change the setting of the fieldmonitor to 4/3 and then I have black basr to the left and right and use it as a 5.6 inch monitor.

The sensor of the K-5 at least doesn't get as heated as with the K-7, but no test on how that is in warm environment or with really long exposure. No problem with it taking 25 minutes (720p at one star) for 3 times.

Are you saying the HDMI output from a K5 is only 640x480 (VGA) i.e. the only way to get a 1080P (HD) video out of a K5 is to copy the mpeg file from the SD card?

Just during recording, because when you play a recorded file you do get FullHD output. During recording VGA and the actual picturesize (black bars left, right, top and bottom) is 640 x 360 pixels.

I have a 64gb SDXC card and can confirm that even with the XFAT filesystem, the camera limits file sizes to 4gb (the upper limit for pre-SDXC cards). What this means is that at lowest quality settings, the camera can record 25 minutes of video at a stretch, but at highest quality, only about 5.

Pentax theoretically could raise the recording limit for SDXC cards to 30 minutes in highest quality mode by making a minor firmware change. However, anything beyond that would make the K-5 a camcorder under European Union import laws, requiring higher import duties.

While it is possible we could see the recording limit raised to 30 minutes for all formats with a firmware update, it is unlikely that it would go any higher than that.

I have been reading this thread with interest, I have just bought a rode stereo mic to record our local open mic sessions and some surfing footage. All of this I want to do in high definition. Two things I need to be sure of can I record 4 gigs stop for a minute or so then record an other 4 gigs. I have an 8 gig Sandisc extreme 30ms and A 2 gig one as well, would a 32 gig class 10 Sandisc be my best option for recording video?

Osama,

I've used my camera pretty much exactly the way you describe without issue (recording live music with an audio-technica external mic, fill 4 gigs, off for a minute, 4 gigs more). The temperature warning does come on after while, but I've never had it stop mid-recording.

Before I got my SDXC card, I was using a 32gb class 10 and never had any bandwidth issues. When I first got the K-5, I also did a few test shots on an older 2gb card and never managed to get the camera to choke, but I would imagine that faster would definitely equal better.

Also, keep in mind that at 1080p, top quality, a 4 gig file is only a bit over 5 minutes. If you are going to be recording a lot of high quality video, the space goes fast. And if the songs you are recording are over 5 minutes, you might want to bump the quality down to get a bit more record time.

thanks for the information DC do the SDXC cards make much difference
