Sony F5 "hacked" for internal 4K?

Paul Ream from ExtraShot.co.uk claims to have managed to record 4K internally in the popular Sony F5 camera. That’s big news as internal 4K recording in the XAVC codec is one of Sony’s major USPs for the F5’s bigger brother, the F55. (Another one is the F55’s global shutter. Read and watch my extensive  Sony F55 review by clicking here.)

F5tease1 It’s still a bit of a mystery how Paul did it, but he promises to enlighten us in a podcast to be published prior to next month’s IBC exhibition in Amsterdam (the cinema5D team will be there of course). It might not even be a hack at all.

In the meantime, watch what Paul shot in 4K, supposedly internal on the F5 – you’ll have to head over to the Vimeo page of the video to actually be able to download the original 4096 x 2160 pixels file though. Head over to the full blog post here.

Here’s the gist:

After long nights of cold coffee, we finally found what we were looking for… Internal 4K on the Sony F5.  We all knew it was in there waiting – just needed that flash of inspiration that sometimes comes with a good curry!

The great news is, we’d like everyone to try it out.

All you have to do is listen to the next episode of the ExtraShot podcast and we’ll tell you exactly how we did it.  It’ll be out just before IBC.

Until then, just a couple of 4K shots to whet [sic] the appetite…. (Obviously, Vimeo streams at HD max, so you have to download the original file (4096 x 2160) to see the 4K in all it’s glory – not particularly proud of the pictures, but simply wanted to record something straight after getting it working)

“Whet” doesn’t need “[sic]” alongside it — it’s the right word in this context and it means “sharpen.”

Love,

Haven’t tried the HDMI or SDI output as I don’t have a 4k monitor. Also yet to test if audio is working while recording in 4k (didn’t have my mics with me) but I’d assume it would.

I did Paul’s ‘hack’ to my F5 this morning and it seemed to work all ok. Can’t playback clips in camera but they come into and export out of premiere just fine. The hack itself is ridiculously simple and has nothing to do with the firmware at all.

That takes some guts to hack into a $17,000 camera

If this is an accidental ‘hole’ in the firmware that he is now exploiting, I’d assume that a future Sony firmware update will close this ‘hole’? Sony might even not advertise the ‘fix’ when they release the update.

that would be fine. all you would have to do is torrent the old firmware no?

Sony continues to dominate the high-end market.. and the low-end.

Canon seems years behind.
