50D Raw video

[paulforte]

I still have the pink picture when I zoom X5, I don't know if it is normal?

Pink picture here too. Have yet to find a fix (if there is one)...?

Like wise. And when the shots are processed through RAWMagic I get harsh, crushed, ugly frames with white borders on the bottom.

Pink screen is normal. No fix (yet).

Got my Komputerbay 64GB 1000X, yay!
First of all, I'm happy. Now I can record the max 3:2 and 4:3 resolutions without problems.

But I wanted to know how far I could push it, here my results.
Didn't do anything special with it, formatted in camera.

50D results with 12june build by Gregory:

(hardly idle means just a few ms, no %)

1584x892
16:9 24 fps = continuous @68mb/s (17% idle)
16:9 25 fps = continuous @ 68mb/s (13% idle)
16:9 28 fps = continuous @ 64.5mb/s (hardly idle)
16:9 29 fps = 700 frames @ 64mb's (no idle)
16:9 30 fps = 400 frames @ 63mb/s (no idle)

1584x1058 (24 fps) = continuous 67.5mb/s (hardly idle)
1584x1058 (25 fps) = 800 frames 67mb/s (no idle)

5x zoom
1920x818 = continuous @ 66.2mb/s  (5% idle)
1920x872 = 1700 frames @ 65.6mb/s (no idle)
1920x960 = 300 frames @ 65mb/s (no idle)

2000x836 - 1700 frames (hardly idle)
2000x852 - 999 frames (hardly idle)
2000x910 - 350 frames (no idle)

Isn't it strange that the speed goes down, when higher speeds are needed?



camera crashes when benchmarking in live view movie mode...

In my USB card reader it benchmarks (very quick test) at 122mb/s read and 93mb/s write.

[a1ex]

Either the DMA gets overloaded by larger frame sizes, or FIO_WriteFile returns a bit earlier (so ML overestimates the speed a little).

Good to know - thanks.

[paulforte]

Off topic I know, but does anyone have an external battery solution for the 50D? I was looking to buy this - http://goo.gl/to1vd - but I believe the 50D uses different batteries and so it may not work. Any ideas?

[dhallowell19]

DaVinci seems to be the best workflow. @BoKia - You can pull more out if you open RAWMagic processed CDNGs in DaVinci and set the clip setting to BMD film.

Sorry if this is naive... but is the BMD Film Gamma selection available in Resolve 9 Lite?  I see the dropdown in Lite, but it's inactive. 
Thanks for any info....

latest build with changes to Auto-ETTR (many changes since weekend)
raw_rec module should now keep settings
https://bitbucket.org/GregoryOfManhattan/magic-lantern/downloads/13june13-50D-0d47d7f96111.zip

if you are interested in testing auto-ETTR, don't forget to switch you back to saving raw photos in the canon menu.

speed should be comparable to what Julian just measured with yesterday's build.
cheers

Click on the pulldown menu and select "Clip" should do the trick..

hopefully, there are a variety of fixes 1% has in process which should make the 50D code more efficient.
not sure if there's enough overhead in the 50D's capacity to hit the 1920x1080 - 83 MB/s in zoom mode.
seems like with fast cards, 70MB/s continuous is where we are at the moment.

JulianH do your DNGs come out exactly 1584x1084 and was your frame rate 24.0 ?
(if so, i'd expect 68.8 MB/s as opposed to your reported 67.5 MB/s)

Great work getting better and better daily.. 

[Hokie123]

So I got the komputerbay 64gb 1000x, can someone tell me how to properly benchmark it in camera? I'm only getting a 45mbps write speed

Haven't checked any of the actual files, just let it run in the camera. Framerate was 23.976 (for 24). The reported write speed is changing over time - I noted the average. Most of the times it starts a bit lower and during recording it can change value a bit.

I'll give the new build a quick test and check if the files are ok at 1584x1058 .

/edit: See that I made a typo in my previous post... it's 1058 not 1084 of course.

/edit2: Speeds on june13th build look the same indeed. Getting 800-1000 frames at 1058x1058 25 fps. Continuous at 23.976 fps.

I bought a pack of 2x2000mAh batteries for my 50D they costed around ~15$ They last about 2.5h of CONSTANT recording and about 8h for photography work. Even after 6 months they haven't lost any of their "power" so to speak.
So you could get about 6 of those packs for the same amount of money you would spend on the external battery pack.

There is a solution for the 50D.  The Canon DS8111.  I bought mine at Samy's Camera.  Here's one on ebay.

Just like Bokia mentioned, you can get multiple batteries that are high mAh.  I have 4 2200 mAh batteries that literally last 3 hours.  Use them in a battery grip & you will be set.  I've shot on 12 hour productions with these out in the field over past 2 years with great results.

[paulforte]

The DS8111 is a great solution for indoors. I'm still hoping for a run n gun battery pack! I bought some 2200's, I guess that's the way to go. More the better. THANKS

Another 50d & 5dmk3 test:

[JulianH]

Nice shots Jacub. Your sensor could use a cleaning though And I think the vignetting is a bit too obvious. Wouldn't be able to tell the 5D3 from the 50D shots, but I see you finalized in 1600px.

Great tip! Just been playing with some of my footage in Resolve Lite and it looks really nice. Apart from coloring. the scaling and sharpening algorithms seem to be much better in Resolve than Premier Pro or After Effects.

Good work !!! Thank you !!!

Another 50d & 5dmk3 test:

Great video couldn't tell the difference between the two.  What was your workflow?

[goldenchild9to5]

You are right @Andy600 Davinci upscale looks exactly like the original I don't know what's going on under the hood but it's working beautifully.

Could you refer us to a few models? I'm really interested in this and could definitely use the hardware upgrade ;-)

[Andy600]

@1% - How did you get Display Filters working? I enabled them and recompiled but they don't show in the menu

[1%]

Its not as simple as that. I figured out how a1ex did it for 5DII and ported it. You have to add the code to your repo to make it work.
