Have you viewed the footage taken at 720p raw? I have been playing around with this for the past 2 days and the amount of moire and CA makes it pretty much unusable, but I can take more than 2000fps at 13?? something something resolution. I would only use this shoothing in a dark room...any spikes of light ruin the shot.
#27
this is good stuff! I hope it works well.
#28
sweet, thank you!
#29
I fuguered out that playback is in raw menu. With file manager can you delete files as well?
#30
I only got raw, ettr and dual iso modules to enable? am I missing it in some submenu?
edit: ok, figured it out :)
#31
I was under the impression that raw playback works on a 550d...mine doesn`t. Does it work with any of the builds?
#32
I was in the same boat as you 3 days ago and I downloaded the same build and it all works just as the previous version.
Haven`t tried the dual iso yet, and can`t really comment on lenghts of the raw, because I just did a couple of test shots. But so far, for what I film(skateboarding) raw will probably not be something to use all the time. The crop, kills it. Othervise it looks good, just as long your not glued to the screen, step a couple steps back and it looks better than h.264 full HD.
But as I said, crop, no playback, not being able to erase clips on camera and the fact that a 16gb card would be filled in a couple of minutes are the drawbacks. I was scouting the net the other day and saw that someone developed a software for 550d to record 2 and 4k video, but it seem that it was a hoax. That would be something I would be interested in very much and 120fps :)
daydreaming :D
Short...I would use raw to show off to friends, as far as youtube and vimeo goes, most will not notice the diference. At least not for the type of filming I do.

#33
did anyone use magic bullet instant HD with raw video yet? probably yes... :)
#34
I`ve been folowing this thread for for a while now...has our beloved 550d finally hit a wall? What is the current best thing you can do with it?
I film alot of skateboarding so 14fps raw is unfortunatly not an option for me. Dual ISO...this I`ve seen for the first time today. Does it help with anything but exposure? I guess it can be very usefull for me when a rider is riding inbetween shade an sun. Anything else?
Time to get the 50D?
#35
that would be my setup exactly. can you post a clip or two of the footage?
cheers

hey jagnje,

i recorded it in 50 fps. interpreted as 25 fps or slowed down to 50% gives you a flawless 1/2 speed real slow motion.
if you slow it down by another 50% using sth like twixtor or the foundrys kronos or the retime component of saphire plug ins or any other software using optical flow you can get a real good 1/4 speed interpolated slomo.

but it´s important to shoot with the highest shutter speed possible. the less motion blur you have in your images the better the motion flow based image interpolation works. you can even lower the software slow motion to 25% and still get medium to good results.
but the algorithms really start to struggle with those speeds and warping becomes more and more visible (see the close of the fountain).
it also depends on the image content.

it´s more something to play with than with real value

ok, I know about twixtor...haven`t been able to use it in a manner that I would be pleased, but I haven`t tweaked it much yet. I just thought that your footage was without twixtor, that that much vector information is unlocked in RAW, because if it was that would be really good :) Filming skateboarding in super slo-mo without renting expensive cameras...
oh well :)
Can`t wait for a stable release with at least 15sec of flawless continous footage.

hey guys!

good to hear from the writing strategy.
i thought about something like this by myself. but more in a way of interlacing the image and writing it in blocks to the card.
maybe storing it randomly on the card, so the card can be written on with a constant speed continuously?

i don´t know how the dng files are actually contained as one file. if they are in sequence or already randomly stored.
is it possible to generate a mft type list in that container to restore the correct sequence in the unpacking process on the computer?

or maybe a kind of pre record strategy. you could arm the raw recording process=>buffer gets filled and rewritten for an "optimal" amount and circles for 10 seconds. then kills itself to prevent heat and to safe battery.
then you hit the fire button and the card can take the optimal data stream.

what´s the h264 coder doing? in the 50D it has to be activated to get raw recording.

this is just theory. and of course i don´t know if anything of this is possible or even already implemented.

would love to help with coding, but my coding days started and stopped with the C64...



and i did some more practice tests. wondered, what the also increased motion resolution (compared to interframe based h264. means, h264 dumps not just color and detail information by macro blocking but also motion information which is stored in vectors)

so here you have it: horrible resolution and a nightmare of aliasing but a synthesized 200 fps camera (shot 50fps)


Nice shots. Do I undesrtand corectly...you shot this in 50fps and slowed it down to 25%?

General Help Q&A / 50d H264 modes?

Hello, I`m sorry if this has been posted somewhere before, but I did not find it.
Anyway, I love the RAW video clips that people have got on the 50D, but I wonder if the ussual formats are there as well. Like on the 550D, especially the 60fps at 720p? I Film skateboarding alot and I need slow motion.

General Help Q&A / Re: ISO Confusion (My error or ML's?)
September 06, 2012, 12:38:37 PM
ok, I think I get it now. For the below 100 ISO I have to set the EV.
For white balance I pick the bottom option, press arrow and it adjusts automaticly.
I can stil hardly belive at all of the options you get with ML. Thank you guys!

Hello, first time user here. I think I have the same problem as the user above...I have managed to figure out most of the settings I need, but  when I togle thru menus in video mode I just canot get all of the available ISO values. If I use 100/160 I can togle the 160, 320 etc, but When I try to use ML ISOs it just gives me standard canon values 100,200 etc. Also in neither mode I can`t acces below 100.
Everything works like a charm in manual photo mode.
Also, I haven`t figured out the white balance completly. Is there a way to have auto white balance? So I can see what would the camera use on its own and I can learn.
I am using 550d with the latest magic lantern.
I have a feeling that I have to set something in Canons menu but don`t know what.
Regards
