You're crazy, but I appreciate your crazyness!

There is nothing crazy about this historical fact. =)
read books about Cyprus

nobody doing any movie about it yet
but its very interesting how cats were protecting humans from snakes in cyprus

at least i made use of canon 50d for some cultural and historically valued, maybe spiritual idea)

ADJ can you tell me what you use for video editing.
Thanks for taking the time to post your replies.

What I have been using for SD or HD has been very basic editing with Avisynth, Virtualdub, and sometimes Cuttermarran before encoding for DVD or AVCHD. I haven't needed to pay for a fancy NLE application since I don't do editing on a daily or a weekly basis.

For ML video I'd like to get something free but which can do the job if that's possible. Because of the learning curve with new software I'd prefer to find one I like and stick to it. I downloaded Lightworks and ivsEdits LE last week and had a look at some video tutorials.  As with the dng processing I'm finding it hard to find a solution with good tutorial support that isn't payware. Lightworks naturally seems to have the most support. ivsEdits looked good too but they've only added a Tiff importer recently (via Targa) and I haven't seen anyone on here mentioning it. Ideally I'd like a workflow which works on freeware so I can spend any money on cameras, lenses or computer hardware. I was on holiday last week but now I have less time to read. As always I appreciate the help people give on here which can save hours of trying to figure stuff out by myself. Have you used a lot of different editors yourself or do you stick to one in particular?

Perhaps I should mention my PC is W7 x64 8GB Ram about 4.3GHz OC in case that makes a difference.

50D vs Red Epic
« Reply #2977 on: August 20, 2013, 09:23:24 PM »
Hey dear Raw'ers ))

Recently I was shooting some footage with Red Epic at 100-200FPS with the resolution 2K.
I thought it would be a good test against our prominent RAW monster )

So please find attached some sample shots from 50D and Red Epic at 2K in comparison.
All shot at 320 ISO

Basically, I congratulate you all with our choice  8)


50D image (upscaled to 1080p) and RedEpic 2K image (100% crops with my CC - black+white + some sharpening but not too aggressive)

Here are fullsize 100% crops (jpg'ed for web):

Tragic Lantern - good to know; I've been using the July 27th build, but I'll take a look around. It's the Bolex Moller Anamorphot 19/8/1.5 which has a 24mm rear thread. This is mine - http://i.imgur.com/RBPNjRr.jpg - I've been using it with the Zeiss 50.. 1.4 which has a 58mm filter thread. BUT, the Zeiss does create a lot of chromatic abberation which I'm a little disappointed with (especially for a $700 lens) so I may experiment with an older Nikon or Canon FD.

24mm thread, thats amazing that there's no vignetting. Are you shooting 1584 x 1058?

It's a bit hard to see which blending mode you pick.

Nice one Rommex, it's a good comparison 50d holds up really well. The Red would trash the 50d in low light though I bet.

Thanks lomka for the tip  :D I think making this with real film gain is still better.

Search in google for film grain and download it, use the blending mode in after effects and the % in the opacity. I think now you also got filmconverter, plug in.

See also http://gorillagrain.com/ or http://rgrain.com  you have others also good. I think real film grain is more organic... but its a good tip.

24mm rear thread and 39mm front thread. And that image is on a 50. I actually just shot some footage with the Canon 40mm 2.8 pancake (which is as wide as I can go); here's a still, uncorrected - http://imgur.com/a/mAKsR - as you can see there's only a tiny bit of vignetting here, but basically none. I actually recorded at 1584 x 892. Dang it! Didn't realize I could go higher - haha. I will now. Thanks :)

Molinsky try this download Andy's Tragic 7 build after you do don't change anything from it, than simply add the 50D firmware in that folder that's it.  That should solve all your problems..

@Andy600 & @goldenchild9to5

Thank you so much, guys, for all the help. I'm sorry about this late reply. Unfortunately (or not), I work all day and only have the night to test everything in the camera.

I deleted everything I would not use in the card: pdf files, other cameras firmwares, config files... and it works for now after I tested some customized videos.

The thing is: I use a very crappy card. It sucks so bad, has only 29mb/s of write speed. That's why I didn't posted any test, I'm waiting (forever) for my Transcend card. It is possible this card be the reason of such instable interface overlay?

Dammit, the overlay is flickering all over again! It only stops in two situations: either turn the Global draw off or turn the raw video mode off.

Is there a way to go above 1/120 shutter? I'm using tragic lantern and I have exposure override activated. (I don't care about the stutter in movement)

Short comparison video I shot between the Canon 550D's H.264 and the 50D's raw for those who are considering to make the switch :)

While at job, I've been making some research and found that my issue (Canon gui flickering over ML overlay) is not new in the 50D raw environment.

for those following along at home, the empire strikes back and the canon gui is showing up during raw recording in my recent build.
you do NOT want the canon gui during raw recording as it will slow it down.
ideally you'd want to use magic lantern histogram and spot exposure during raw recording.
(waveform is based on YUV not raw so it may not be entirely accurate during raw recording)

Active and moving? that's not quite good.

The only easy solution that I see right now is to try globaldraw on and all other things disabled.

Or... hack the CONFIG_KILL_FLICKER code so Canon GUI can be disabled from some other tasks too. Not sure what is the best way to implement this; maybe a reference counting like LV RAW mode from raw.c.

Seems there is a CONFIG_KILL_FLICKER ifdefs somewhere (found it instantiated at internals.h?), because the problem occurs when I load the modules. I also tried some stuff already recommended, but nothing solves the bug. Since only myself, apparently, is having this problem and I keep deleting the config file, is there something I have to set in the Canon menu?

ps¹.: funny thing, I also found a lot of overlay bugs reports (i.e. http://www.magiclantern.fm/forum/index.php?topic=3697.msg36245#msg36245 and http://www.magiclantern.fm/forum/index.php?topic=1886.0 )
ps².: if someone is not aware of the problem I'm dealing with, watch this video:

Well, did everything from scratch. Formatted card, updated to ML 2.3, changed the ML folder and the autoexec.bin with the ones in the build and... everything ok until I change something.

I'll try again tomorrow

Andy
I would like to share this first video test (handheld)  that I shot with Tragic Lantern 2.0 and also say many thanks for you guys! I am very happy with the result of the videos I got with may old 50D!

ML grayscale preview is fighting with canon overlay. Change the preview mode in the raw module.

Thanks for the reply, @1%. But it's flickering with any of the previews. Actually, I made a very extensive evaluation sequence here and I noticed that it's really something in the raw module only. I let every other module loaded (but the raw_rec.mo), and it's ok.

But load the raw module and try to use it... BAM! I have to shoot without any ML overlay, totaly blind about the right framing, histogram and stuff.

A friend of mine says that I like to play with "Flickr", the camera. Pun intended.


I laughed, but I'm getting frustrated.

Its not doing it to me. I think an extra black bar is drawing with raw_rec + movie mode.

I did find some display filters fight with the grayscale preview, ie defish.

Hi,

I copied Modules folder under ML directory, however nothing happens. Please let me know what shall be done in order to enable it in my 50D. Do I have to copy the files raw_rec.o, raw_rec.mo & magic.sym in another folder?

Thanks,

Ed

@Molinsky - Can't reproduce your problem.

Can you upload your magic.cfg and raw_rec.cfg files?
