550D/T2i raw video recording port official thread

[dlrpgmsvc]

Let me know what are you tinking about this possible discovery of mine : There are clues that, in order to make room for the raw_video_rec module, we used the shoot_malloc memory to put there the ML code, so shrinking it, so we cannot have more shoot_malloc memory anymore... look at this : http://www.magiclantern.fm/forum/index.php?topic=5071.0

Hey, I'd like to congratulate the ML developers for another revolution on the DSLR history.
I've been testing this on my 550D and I'm loving it, but I noticed in the build that I'm testingthat only resolutions up to 1728x672 are avaliable, why is that ? Is it a temporary problem or another limitation of the camera ? Because with low framerates one could get more that that... So, technically, could we get it up to 4K, or at least 2K ?

[Alex546]

Could it be possible to record your RAW movies with a higher resolution but monochrom? Maybe 2k or 4k on a 550d.


550d, 1280x425(streched) @24 fps:

[1%]

Not likely.

You can get higher res in 5x mode, go into 5x mode first then turn on raw. You might want to go into zoom setting in ML and disable 10x mode so you don't accidentally crash the camera while in raw and switching to 10x mode. I don't think it is anything wrong with the max res we get, it is just the max size our camera can do.

lack of time pushed me to sell one of my t2i' now I'm considering switching to EOS M, faster cpu, faster card-io chip, maybe a better luck. but I'm still keeping my old t2i.

so if u go into 5x before turning on raw this helps the camera? im confused im on a 45mbit card and im not able to go to anywhere close to the posted resolutions that have been stated here. also i heard someone saying that its possible to view your raw files on camera is this possible

Yes, with the new build I just posted yesterday, you can use the new filemanager to view the raw clips, or if you get the tragic lantern build i posted on the same post you can view your raw clips in the raw video menu too.

The filemanager is in the debug menu at the top.

And going to 5x mode does not help, but it does record higher res, you will not get 24fps, all rules of write speed still apply, I use the higher res for timelapse at 4fps

@mk11174: the mod 1% did, after which we on 550D obtained more shoot_malloc memory, I think is that: https://bitbucket.org/OtherOnePercent/tragic-lantern-2.0/commits/a926b83dc3e933e42341baa3bd145ffd2aff7e81
So can we try to lower the new value, say put 0xc70100 instead of the preexistent 0xc60100, just to lower the autoexec.bin memory and so (hopefully) increase the shoot_malloc memory pool ? 

[shawnwytch]

Does Lowering The Qscale l to 0.50 use less memory? so it records at a lower bitrate

If you mean for Raw, no Qscale has nothing to do with Raw.

This is where he got more memory.

Good to know ! So... in order to squeeze more shoot_malloc memory, do we can play with this ? --> https://bitbucket.org/hudson/magic-lantern/commits/39d536e2b72c39b81855526fbd08f4281931ccbb     what do you think ?

[marregi]

This is my test with 550D Raw at 1024x448 "without" problems while recording. Sometimes camera stops recording at frame 70-80, but after that I can record without problems. I see a lot of issues but what else can we expect? Less aliasing? more resolution? I still watch a lot of artifacts but I hope someday this can improve thanks to all developers around here!!! Thank u all for your work, it´s amazing!

[wharfrat22]

Looks really nice.  May I ask what lens you are using? This thread has taught me a great deal.  Thanks to all that has contributed.  Very inspiring.

[igouroum]

Being in Paris for a few days, I decided to shoot some test videos, mostly at night.
Didn't have any tripod / Slider, etc on me as I didn't have much room to spare, but decided to shoot
something regardless at about 1am.
So yeah.. check it out and tell me what you think! Feel free to ask any questions, I'll answer within a couple of hours.
Also, read the description!

Cheerios,

Marc Wolff

try for 50D NSTUB( 0xff9829b0, FIO_SeekFile)

first build with FIO_SeekFIle that has worked - thank you - @Chucho explained in another thread about offsets from the 1.07 firmware and calculated with a couple of bytes of your value.  raw_rec module runs and plays back on 50D.
thank you.

With all due respect - this thread is about 550D Raw Video - please keep posts pertinent to the subject.

Greetings
Mk111174, you stated yesterday that the 500d is getting 1280x400+ at 24fps, is this in raw?  How?  I have been trying to find a thread on the 500d raw and have been unsuccessful, please turn me in right direction.  Thanks and please don't be angry if there was somewhere else to post this.  Thank you.

I've been testing with the ML_Fileman_Raw_Tragic build and sometimes all I get is a bunch of weird frames like this:



This clip was shot at 1728x992 @ 5fps in PAL mode (does that even matter here?), it has already happened when I tried to use the 5x Mode.

What can be causing this ?

These are just random bugs, I get this every so often especially when doing 5x mode no matter what build I use. I also get them more using fps hack. Every camera model is probably differ though so it might be something that will never be fixed or might be something that gets fixed by coincedence one day. I just delete these frames when they happen, I am so happy with Raw video now that I can risk losing a few frames here and there.

I am not a developer so I am just like most of us in here, just guessing at what is wrong. The real smart ones are Alex and 1% those dude know what they are doing!
