Tragic Lantern / Re: Raw video on 50d and 40d

CPU usage by canon/ML definitely affects write speed. If we break more stuff it will be faster.. I'm hoping for maybe 10Mb/s more somehow... not expecting the 100s on UDMA 6 but from SD cards should only be 5MB or less under max write of the card. Just 5 more MB or even like 2 or 3 and 1080P will be continuous. 10MB more and probably stable.
That's great to hear, thanks a lot to all of you for your continuous effort. Btw, is there a reason, aka technical limitation, why the 5dmkii still is doing only 70mb/s compared to the 81mb/s of the 50d?

Tonight there is a Jazz concert in my town and my nikon lens adapters just arrived, I'm still on an older build and I wanted to know which is the latest stable/fast one to try out zoom mode. Was the 80mb/s wrong info? As I'm reading 70megs lately.

A new test.
was that in 5x zoom mode?

Zoom won't need much upscale. I don't think it has moire in zoom.
There could be moire, but the 50d has a very strong aliasing filter so I don't think it will ever show up.

Btw, does anybody know if the 5x is really a 3x crop, and if the same applies on the 5dmkii.

Question: since 5x zoom multiplies field of view by 5x times what lens mm on a crop sensor would I need to achieve 50mm? Something like fisheye?

The thing goes like this, 5x zoom is actually 3x additional crop (please correct me if I'm wrong), then there is the 1.6x canon aps-c crop.

So 50/3/1.62= 10.28mm lens will give you a 50mm equivalent fov, depth of field will be the same as on a 10mm lens, so no shallow depth of field.
 
That would make it slightly smaller than a 1/1.7" sensor area which has a crop factor of 4.55x compared to the 4.86x crop from the 5x zoom mode. I don't know if it exists, but if you put a m43 7-14mm lens on this you could get a 34-68 lens which should be ok for most shots.

@ted ramasola & duncanidaho25: Nice, I got a shot of the supermoon a couple days ago too! I just have a cheapo Canon 300mm lens though. Lots of atmospheric distortions were visible. I compared it to a shot I took a couple years ago of a regular full moon and it was indeed a little bigger!

edit: Btw, the moon was also a yellow/light orange in appearance at the time of the shot and it turns out that way in post when I use the same setup I have for regular daylight. What do you guys think about white balancing it to make it gray?

Well, you have to turn the slider to the left = less temperature. But the surroundings will become more blue.

If g3gg0 figures out something from the sensor logger.. maybe.. good luck recording it tho.. 1080P or 1038 is about where it maxes write speed. Would help for silent pics.. hopefully no more corruption on those.

Yes but if there were 2560 for example, and you could still get 80mb/s, that would make 2560x780@24 or for a more useful format 1:2.50 would give theoretical 2234x893@24.
Anyway, it's just daydreaming ^^.

From where exactly. Its zoom size or regular size.

I was asking about zoom size, I thought when reading a comment by Andy600 that maybe the zoom stream was bigger than 20xx X 10xx  but apparently it's not that way.

Andy, did you have another look at that EDMAC thing you were looking at to get more resolution?

75MB/s on a 600x Transcend  ;D This is crazy! Nice work man.

@Viente - 1534 is correct. It uses the 512-byte rounding method so 512x3 = 1534. It's less work for the CPU to process

I guess it would be useful for the raw_module to auto-switch to the 512-byte rounding method at 30p and in crop mode. That way we retain max width in normal mode. Normal mode can shoot continuous (16:9) using the old method so it doesn't benefit it as much. Easy done with 2 modules but can it be done in 1?

BTW 1% - I haven't a clue if this is useful but I was looking at EDMAC and #5 is 2912 x 1083 - maybe larger frame sizes are possible? (I don't understand EDMAC TBH)

that would be amazong 2500x780 or something like that would be 80mb/s. Nice for panoramic shots and fighting against the extreme crop of 5x zoom on 1.6 sensor.

Can anyone tell me, would a lens with Image stabilization help much?
And what is this stuttering effect on panning shots, is that a result of FPS override dropping frames, or something else?

Well lens stabilization isn't going to help you while walking around with the camera in your hands, specially not at 50mm on 1.6x crop.

The stutter might come from importing your 24fps secuence as a 30fps material but having a 24fps composition. check it out, right click on secuence and click interpret footage, should be at 24fps for a 24fps secuence. Has already been discussed in a lot of posts.

Rolling shutter is not going to go away even with raw (makes no difference).  50mm + shake panning =terrible rolling shutter.

Anyway, that's all basic stuff, nothing to do with RAW.

Is there any way to have slow framerates without rising exposure compared to normal framerates? (and without having to use an ND filter)

Nice to hear 1%

By the way, where do I change to Movie mode? I still get the pink tint during 5x zoom in live view so I guess I'm in photo mode but can't find the setting in the ML menu.
Sorry:

Most cameras have a dedicated movie mode on the mode dial. In this case, it's obvious what movie mode is.

However, the following cameras do not have a dedicated movie mode. For these cameras, Magic Lantern considers the following configurations as movie mode:

For Canon 5D Mark II: in LiveView, with movie recording enabled AND LiveView display set to Movie. Tip: you can change LiveView display type from Expo menu.
For Canon 50D: in LiveView, with movie recording enabled from ML menu.

Even in moviemode I still get a pink preview (June 6th build)

Here two screen grabs, before/after defringe in ACR to get rid of false color detail:

A quick test, worst case scenario for me, high DR and very fine detail and shot with a pretty bad 28-70 canon 3.5-4.5 at f9 (waiting for nikkon adapter). I got a lot of aliasing. I made some slides which turned out to be horrible but at least you can see the movement which induces aliasing.
1592x636 1:1 mode, build May 28th. Had to shoot in this low resolution as I'm still stuck with some old 4gb 32mb/s card.

Workflow. raw2dng->AfterEffects->h264 (I tried to compile the compositions and use them in PremierePro but I was getting strange speed jumps)

I fixed the alisasing with defringe option in ACR and sometimes with NR ,color 100, colordetail 0, although you have to be careful not to kill your colors.

Are the zoom 5x mode colors fixed in the new build? I can't fix them in ACR on 28th may footage.

120
Or perhaps, (if lighting allows) stop down as far as you can go, to introduce diffraction... I think that's essentially the same as what the aliasing filter does.
I tested that on the 50d but it looks very bad as you get everything in focus and you start getting aliasing and halos everywhere. Best thing is to have just a few objects in focus and the rest slightly out of focus, this makes everything nice.

got everything ready....

but apparently my live view button doesn't work? It only turns on when i turn on/off my camera?  :-\
I can manually turn it off in the menu but i can't turn it back on again unless i turn it off which makes raw recording not possible?
Am i doing something wrong? Does it has something to do with my lens? its a Tamron 28-300mm...
have you activated live view?

Just got my 50d with grip. I've been trying with some Sandisk Extreme IV 4GB card. On full res I get 98frames with global dram off and 109 frames with global draw on. Around 300-400 on 720p.

Zoom mode looks pretty bad, but I think that's the cameras limitation.
Has onyone tried out a 600x Komputerbay card? If anyone has and gets continuos rec on 1:1 I will go for that one.

Thanks to all of you who made this possible, I'm having a lot of fun!

My first 1920 x 1080 test on line.

Shot at 1576 x 880. 24 fps. 0.9 bit rate. Canon 50mm F/1.8. Sandisk Extreme 32GB 60Mb/s.
raw2dng>AE: scaled and light grade. 16 bit. scaled by 122% to 1920x1080> exported as ProRes 422HQ>FCP7 Light grade / cut.
How many frames did you get before skipping?

Btw, looks very 16mm ;)

Has anybody tried silent pics lately? I was wondering what the max resolution in 5x zoom mode is.

Being able to isolate colors with MUCH more accuracy is a breath of fresh air compared to the usual h264 you get out canon. The image just doesn't fall apart immediately I love it.

HOWEVER, does anyone know why I'm having these frame rate problems? ML RAW says I'm shooting at 24p, when I convert to dng with RAW2DNG it reads as 24p, but if I try to transcode into any codec or even drop raw Tiffs right onto my timeline I get playback as if it's 12fps, then I have to retime it by 2x just get close. Has anyone else experienced this?
Well that used to happen to me doing timelapses in AE, I forgot where you can change the import settings (do a quick google) but you can always press "interprete footage" by right click on the secuence and change the framerate to 24 or 23,976

[edit] I found it, in After effects -> Edit -> Preferences ->Import ->  Image secuence -> set to correct framerate.
