Raw Video / Re: 550D raw video recording port official thread

« on: June 13, 2013, 02:52:27 PM »

hi everyone,

here´s some low and shallow light testing. half of the material was deleted by a mistake and i had just a photo ball head tripod...
yeah.... and it´s a little bit trippy 

workflow this time@work:
ACR=>AE (resizer to 1080p)=>dnxhd 10bit=>Media Composer

That was absolutely stunning!!! It's nice to finally see something that isn't just cats, dogs, flowers, cars, or telephone poles! This really illustrates how much RAW can help. Care to share what settings you used on the cam?

I would love to try it too. Does anybody know if AutoETTR is available on the 550D port of RAW recording?

Anyone interested, I enabled a bunch more things, I think it is at its max though, but seems to run the same as before

By the way, this is from the latest changeset as well so all up to date.

Awesome! I am having trouble installing it though. When I try to update to the FIX2 firmware, I get the following message:
"Update file cannot be found. Please check the memory card and reload the battery and try again."

Thanks!

If we can get a 550D build I'll engage in testing as well.

Yeah, if this comes to the 550D, I'd love to do some testing too 
Really hope the 550D is actually capable of doing what the 600D has been doing.

My first post, so my thanks and congratulations go out to all the devs involved in bringing this home.

I saw this post


and I also would like to vent an idea with all concerned.

For starters check out this vid--->

This geeza managed to replace the SD Slot controller board on a 450D with complete instructions. At time 3:16 you can see the board, which by the way only costs $30 from Canon spares.

This got me thinking - what if the board from a 700D has a faster transfer rate and can be used in the 550D/600D etc OR what if a cable can be hooked up to an exterior device like a CF or SSD?

I dont have the skills but a hardware guru could in principle cook something up.

Share your thoughts......

Very interesting...

I'm planning on running a speed test on the 550d SPI bus to see what I can get. If it can sustain a very high mhz, I might have a few ideas. One being able to record using a computer as a storage device via a ethernet cable. So you'd plug this small SD card connector into the card slot of the camera, then it'd go to a small conversion board, then ethernet to the computer. Much like the SI-2k camera.

Also, I think CF cards communicate with an ATA interface. I think both parallel and serial. So if we could create a connector, it could be very simple to slip it into a CF card camera (5d/7d) and have it connect to an SSD with a PATA/SATA interface. Cheaper, faster, larger drives!

So it turns out the 650d (t4i) can support the high speed UHS-I cards!!!!

I don't think the UHS-I pins on the cards are supported by the Canon DSLRs, only the normal interface. So you're still going to get the normal SD card speeds whether it's UHS or not. I have been designing a device that plugs into the SD card slot of the DSLR and accesses the SPI pins. An ARM chip then emulates an SD card with data storage on a FAT32 partitioned SSD. This would allow very high data speeds. That will erase the problems of the SD card being too slow, but I have no idea how fast the SPI Bus on the canon cameras can go. Does anybody know of the max mhz the bus can run at?

Thanks

The forum user 1% has put together a compiled build for the 600d here (be warned that the SD card limits you to smaller than HD resolution):
https://bitbucket.org/OtherOnePercent/tragic-lantern-2.0/downloads

I had luck installing and using it, but no matter what frame sizes I specified, I got those pink weird cropped frames every 5-10 frames (Using a transcend class 10 card, which others said they were able to use on small resolutions without issue).  I'm extremely excited about the RAW possibility, the files just have so much lattitude!  Any tips on how to get pink frame-free video on a 600d from someone who has tried it?

Will it work on the 550d?
