QuoteDoes 5dMk3 support UHS-1, I think it has dual slot?
Sadly, 5DmkIII' controller don't support UHS-I rates (that's why it is reccommended to use much faster CF). 650D is the first Canon DSLR with UHS-I support.

Is there a way to load in a RAW file off SDCARD into RAM, pass this through the encoder at various compression settings, then measure the resulting difference between these clips with the MSU tool? This would give a repeatable starting point.
For real, you'll see no difference with still scene - with bitrate >20mbps it will be perfect

600D has no 100k, I think 1250-2500 is probably as high as anyone will go normally. 1250 and below for most cases otherwise you get noise. Also encoder will just be encoding junk... I can record really high MB of black/underexposed but that doesn't translate into real performance in the field. Recording will just stop when scene is correctly exposed and there is movement.

There is no difference between any movement and noise. Noise is real stress-test, because amount of noise have great impact on required bitrate.
600D can set ISO up to 632000 (higher value decrease brightness for me). Just open ISO submenu, set analog ISO to 3200 and increase "ML digital ISO".

Easiest way to shoot static - close lens cap + set extreme ISO (around 100000)

We do :-p ? Please point me to the source, I've missed that :-o
just search for some video ISO comparisons - ISO 160 is less noisy than ISO 100, ISO 1250 is less noisy than ISO 800.

Quote5k works for me... I just use the disp shortucts and it will get there. Its just 3200 + gain either way.
I don't get it with shortcuts in 550D/600D. Do you have 60D or 5DmkII?

Hello!
We all know that the best ISOs with minimum of noise is 160, 320, 640, 1250 and 2500.
Why ML don't offer "low-noise" ISO 5000 and 10000 when toggling ISO? It is possible to set such ISOs manually but it takes time.

Hello!

Suggestion from http://vk.com/onichan:

Push-button for AutoISO just like AutoWB.

Will be handy when it needs to adjust expo as fast as possible without touching aperture and shutter.
#133
Good way to see difference is to record with high ISO (3200+) something with fine details.
With bad quality this fine details will be blurry and smudged by noise. With good quality this details will stay fine and noise will be more detailed too. (here is example)
#134
1%, very nice! It looks like I-frames don't use buffer, and P-frames use buffer.
So it seems that we locked with quality - high bitrate ALL-I should look like low bitrate with GOPs...

You can do by Digital gain LR.
But range width is tight.

Are you sure that it will affect clipping?
I think that if you get clipping sound with analog gain - you will get clipping even with applied "minus digital gain". Or am I wrong?

Thank you very much for your work!!!

Is it possible to solve problem with stuttering of audio in first seconds of record?
I thought that on 550D/60D there are no stuttering...

I couldn't get 0.5 to show anything on the audio meter and no audio being recorded whatsoever.
Enable audio recording in Canon menu, enable ML audio override, increase Analog gain, select internal mic or auto input

As I see in this thread Limits be gone - it is possible to patch MOV container in-camera.

Patching MOV will be great with "FPS override" - so it may be possible to patch container of recorded file to make it's FPS same as "FPS override" value when it was recorded.

This was taken out. The light from the screen at maximum brightness was rather lame.
I really see no reasons to take it out...
It helped me once, when I didn't had lighter and need to light up some part under hood of a car - it was really bright.

This feature's goal is smooth rack focus velocity for more organic look.

Current rack focus velocity is linear so transition it makes is not smooth.

But focus transition can be smooth if focus speed will vary – fast at start and slowing down as rack focus reaches its end point.

It can be achieved by adjusting "step size" over time – starting with biggest step size and slowing down to smallest step size as it reaches end point.

I know that current rack focus implementation don't know where it's end point - it simply changes focus defined number of steps. Is it possible to have rack focus which is based on memorized focus distance?

Hello!

Canon 600D

Is it possible to make digital zoom 3x<->1x switchable while recording?

I faced this issue too

And I have issue with muted sound with internal audio control after I turn off ML audio override.

How to set mvrSetGopOptSizeFULLHD? Would settign the gop opts to specifics instead of scaling produce equivalent results? I want to try all I frame footage.
I don't think that all-I will be good idea, because it requires higher bitrate with same image quality.
Increasing GOP length should help with increasing quality maintaining same bitrate
#145
Thank you for all that you do here. Hope your investigations will result in better bitrate control.

Just some test of current ML birate control, not with the version posted above (ISO 6400, 1/50, sharpen filter, 400% crop with 2x upscale)
Original 45 mbit

QScale16 165 mbit (in motion details looks even better)


High bitrate really helps to keep details with high ISOs
#146
But what about details in the dark area?
Overall dynamic range of ISO 25 will be 2 stops less than ISO 100? (with better highlight roll-off, but crushed blacks by 2 EV, yes?)

So here is a simple guide showing how to change your ISO to ISO25 while normally ISO100 is the standard lowest ISO on most of the Camera's. It increases also a bit of the dynamic range plus also able to let you have more lower ISO range.
Are you sure? I think that the best dynamic range only possible with native ISO100.
I think that ISO25 is the ISO100 with cut of 2 stops of dynamic range. Is it wrong?

Duplicate Questions / Re: 3k or 4k on 600d?

Hey, ass5001, there are no 3k or 4k video on GH2  :P

Canon 600D can make 5k but it is photo, not video (just like 4k with GH2 is photo mode, not video)
