Tragic Lantern / Re: Raw video on 50d and 40d
July 31, 2013, 09:10:58 AM
Soo, I stopped following this thread at like page 80 or something, could someone give me an update on what version people are using and getting the best results? Is it the Nightly Build-version?

Thanks!

Can anyone confirm if they've broke the hard limit of 60 MB/s with the 50D?

My Lexxar 1000x 32GB card peaks at 63 mb/s, but runs stable at 59 mb/s.

Raw Video / Re: 60D RAW video - it's working !!!

I don't know if anyone noticed this, but when you zoom in to 5x mode in live-view and then fiddle with ML RAW Video settings, it actually allows you to capture huge frames up to 2.5K width... But it obviously fills the buffer real fast, I managed only ~60 frames or so while 1280x544 goes on for nearly 800...

What memorycards are you using when you get almost 800 frames? How many FPS? I get 615-frames with 25FPS, and 95MB/s memorycard - and I also get the same result with my 45MB/s cards!

Raw Video / 60D fieldtest
May 30, 2013, 07:24:13 PM
Hi!

I saw the 60D hack this weekend and decided to take it for a spin at a real fieldtest.
At the time when I installed it on my memorycards, the update#2 was the latest version of the hack, so I don't know what have changed since then.


See my fieldtest in the video below.
I present to you: Khoma at Gröna Lund in Sweden.


(Tamron 17-55mm 2.8 / ISO 200, 1/50, 2.8)


So I took my camera and three SanDisk Extreme 16GB 45MB/s, and one SanDisk Extreme Pro 16GB 95MB/s.
There proved to be no difference between that cards, since - as you know - the 60D only writes at a maximum speed of 20MB/s.

I filmed in 1280x544-resolution, in which I knew I wouldn't be able to record continuously - but I wanted to see how it would work out anyway.

My pre-tests showed that I could record 615-frames in that resolution on my memorycards - but what did surprice me was that I do have a few shots with over 670-frames. Don't ask me how that happened - all I know that it wasn't on the 95MB/s-card.

So what did I find out? Some of you may already have posted about this - I haven't read all posts.

The last shot on the card gets corrupt
- It displays some error with the Header-or-something when the memorycard gets full, and the last shot does not convert to DNG at all.
The camera does not realize that the memorycard is full
- It says [999]-exposures left even though the card is full

That's basically it. The 24-second clips those 615-frames provided for proved sufficient enough for a nice video, though I did miss a few opportunities waiting for the buffer que to empty. In this case the crop was no issue, rather the opposite.

It's all in all a decent raw-video-camera. Since most of us only produce for Vimeo or Youtube, not having FullHD raw isn't going to make this camera useless, I argue that the post-editing abilities of raw is a far more valued option, than having crappy lossy h264 in 1080p.
The upscale hides well in the 5MB/s compression on Vimeo anyway.
