I am joining you on this one.  I wish ML could privide a 3X crop factor making the full frame sensor of the 5D3 of 5760x3840  pixels use only the center portion and came out with 1920x1280 HD video of superb quality.  I think we can all dream about it!

Here is and additional post on this subject:  http://www.magiclantern.fm/forum/index.php?topic=3758.0

Dear fellow birder: thanks for the nice welcome and for the valuable information.  I will looking forward to your test results of the Panasonic GH3, is there no way to use any canon lenses with the Panasonic? 

Of course I value the shallow DOF of FF cameras and super expensive lenses but this is not the most important thing for me.  I value reach far more than anything and of course I cannot afford the expensive lenses.  Also I am a birding guide and therefore have to carry a scope with tripod on top of my heavy camera so large lenses are out of the question.  This is why a I wish there was more interest in the crop video mode for these large FF sensors and also to a lesser degree to the APC sensors, since their low light capabilities are limited.  I my case I live in Ecuador and go to the cloud forest often, and light is pretty scare inside the thicket of primary forests of south America so high ISO is extremely important.

I go to great extents to get the extra reach and currently use a 300mm f/4 + 2x Kenko + 1.4x Canon making my birding setup a Canon 5D3 with 840mm at f11.   This so far is the best reach vs weight and IQ that I can get.  I have been considering the 300 f/2.8 to use in the same setup but the price and weight is too high for my means and body weight!  When I am in very low light situations I use the 1.4x only and for night photography only use the 300mm f/4.

Here are some photos taken with 840 mm f/11 and Canon 5D3

Here is my experience on TC and photography:

http://10000birds.com/bird-photography-equipment-teleconverters-for-7d-and-5d-miii.htm

Most of them would have been useless with the standard 300 mm f/4. 

Now if ML could help provide an additional 3X zoom then I could forfeit all my TC and greatly improve IQ.   I am very, very surprised on how little interest there is on this subject!

General Chat / Digital Video Crop Mode
December 05, 2012, 03:33:35 PM
I use 5D mark III for bird videos and photography.  One thing I noticed is that when I am focusing my video in Live Mode I use the zoom button (5x-10X) and get fantastic resolution to properly focus on the fine details of the birds.  Unfortunately all that resolution of the sensor does not translate to the resolution of the video.  Now I have learned that inferior models such as t3i allow you to actually record the zoom LiveView details.  This would be a GOD SENT tool for wildlife videographers if it could be implemented to the 5D Mark III.  I think canon would boost their  camera sells if they allowed this digital zoom option to be customized ie. 2x, 3x, 4x, ... 10x and to record the high definition video.

I suppose Canon would prefer to sell you a 600 mm lens of $10,000 rather then allow to make use of the cropped mode sensor to get the same results!! 

So the question arises, since I cannot record cropped video in my 5D3 to test:

Assume I put a 50mm f1.4 lens on my 5D3.  Will the cropped video say at 3x on a 5D3, which is equivalent to 1920x1280, be better or worse than using a 3X lens, which for a full frame camera would be 150 mm?

My guess is that the cropped video might be better since there is no downsizing from the sensor full resolution to the 1920x1280.  Of course that would assume that the 150 mm lens is of prime quality.   

I would love to use my 300 mm prime lens with digital zoom of 3x to capture fine wildlife videos without spending a fortune...
Maybe the great effort to do this with ML would be worth lots of money to some videographers like me.  Hint, hint .. big fat donations!

This is a canon bug not an ML.  A work around would be to shut the camera off when opening the door for proper shut down.
#1382
Ask Canon to donate 1DX so that you can port ML!  Canon actually benefits from ML since it enhances its capabilities.  Of course I dont think that ML should make 1DX = 1DC even if it was possible, which I doubt.

Charged battery overnight...

Now camera always disconect from PC when I open the door.  Nothing seems to revert to old situation where camera would not disconect under certain conditions.

On first tryout the camera did not disconnect from PC.  I was able to go up to 30 sec open the door and close the door and the camera would not disconnect.  Changed the "Auto power off" to 30 min and the camera would disconnect above 2 seconds.  Switched the "Auto power off" to 1 min and camera would disconnect from pc no matter what shutter speed.  Swithc "Auto power off" to 30 min and then off and tested buty camera always disconnected from PC.  I had to reinsert card and start the process all over to be able to open door without camera disconecting from PC.

I was playing around with LV dumping A:/ .jpeg (7D) in and using the zoom button to get close ups or crop modes while recording via LV dumping.  The resulting jpeg stream accurately represents what actually shows in Live View thus giving and amazing result at 5X and 10X crop mode.  I imported those images to Vegas and produced cropped video.  Unfortunately some frames were dropped so the video becomes jerky at times.

This is a very interesting feature which adds tremendous value to video crop mode!  It is like putting a 5x or a 10X multiplier to my existing lenses without degrading the image or raising the f-stop.

Is there any hope of producing a jpeg stream without dropping frames?

I also noticed that transferring all those small jpeg files is painfully slow.  Could some type of jpeg encoder join these images to produce cropped video?

I know this is discussed in the (M) JPEG encoder thread but this is over my head and do not fully understand if this will be implemented to the 7D.

Installed the software OK, copied an ML HDR movie to the AviSynth 2.5 directory as RAW.MOV.

Cannot open file "C000000.jpg": The system cannot find the file specified


What am I doing wrong??

I used this software recently and had no problems.

I noticed that you put the raw.mov file in the Avisynth 2.5 directory.  This is wrong, the raw.mov files goes in the main directory along with the main.cmd file.

thanks for feedback.
if it makes sense for future ML releases is still questionable.
this feature is definitely not idiot-proof and will cause a lot of bug reports.

and even if users are warned enough, there might be bug reports that say "in one of 100 recordings my camera fails with ERR70. why??"
thats not what we want.

Maybe that is the reason why Canon does not provide any of the great stuff that we get from ML.

Thanks for all the amazing things and great work that you do!

This whole thing of bitrates is a mystery to me.  It is great that this additional tool has
been added to 7D and now I am trying to figure out how to make the best of it.  I was really
excited with a previous post where some amazing results were presented with ISO 12800
where the denoising had improved significantly by the use of higher bitrates.  Unfortunately
I ran a test myself and cannot find any such results.  I import the videos to vegas 12
and denoise with Neatvideo and the results are the same shitty noise between 1x or 20x for IBP and
the noise of ALL-I seems worst compared to the standard canon video (no ML) until you get up to
10x CBR. I hope someone can provide more details on their workflow to getting such great results
in the high iso world by using the higher bitrates.

Also I have done some testing at low iso (100) with all the options and again the final results do
not convince me that using higher bitrates produces any better video.  For all comparisons I select an area of
about 320x240 pixels of the whole 1920x1080 so I am looking at at 6x factor where I can see artifacts
and noise very clearly. 

I also ran some test on the 5D3 and found out that the ALL-I video quality (artifacts) is worst and therefore
I will only use IBP video with my 5D3.

I don't have the video analysis tools but by looking at the video properties I found the following bitrates for
all my test subjects:


CBR       IBP        ALL-I
            kbps        kbps

No ML    97573                  updated -->(54588 IBP)
1x          49541      43228
2x          88795        95941
3x          89605        150578
5x          90403        228832
10X        91294        268863
15X        96169        272493
20X        98747        243947

Tested 7D with 24mm sigma f1.8

Note that the standard 7D video has a bitrates of 97573 54588 kbps which is below 2X bitrates and above 1X for both IBP and ALL-I.  In All-I video the bitrates go significantly higher but the artifacts show big time until you get above 2x and thereafter I do not see any improvements as bitrates go up. 

Since the video analysis software presented in this post, is showing significant improvements, I would assume that these improvements are at such small pixel size that my eye cannot distinguish and therefore I do not see the improvements that the analysis would seem to point.  Again I am looking at 6x magnification and cannot match VISUAL IMPROVMENTS TO SOFTWARE ANALYSIS NUMBERS.

Any help to clarify this mystery would be greatly appreciated.

Updated since I made a mistake which was pointed out where the standard video on 7D does not go up to 97Mbs.  I must have mixed up some of the videos.

#1390
My visual test show little-to-no difference in noise between 1x or 20x.  I applied denoising as mentioned before but still no improvement in final results.

Also tried the ALL-I at 20x and here I noticed a little more noise at 20x.

Tests at iso 12800
f/5.6 and 1.8
Lens 24mm sigma f/1.8
1920x1080 24fps

If anyone gets better results with cbr 20x then I would like to know how.  It is very difficult for me to post images or videos since I have very limited bandwidth.

Ran some simple test with Lexar Professional 1000x 32GB
card Benchmark  20.8, 20, 53.8
Recording at night iso 6400

Tested the Defult values  =  ERR70

UPDATED October 29:  After I disabled the Audio then I was able to record much longer videos.  Disregard the results below.

Test flush rate (CBR, 1X, OFF, 4, 70%)
Increase flush rate to 8 = record 4 sec no playback on camera
Continue to increase flush rate @ 10 = record 4 sec and 1 sec playback on camera
Continue to increase flush rate @ 15 = record 6 sec and 1 sec playback on camera
Continue to increase flush rate @ 20 = record 8 sec and 1 sec playback on camera
It would seem that higher flush rate allows longer recording and buffers do no fill up.

Test BuffWarnLevel (CBR, 1X, OFF, 20, 70%)
Using previous best settings of Flush rate= 20
Increase BWL 90% = record 8 sec and 1 sec playback on camera
Increase BWL 100% = record 8 sec and 1 sec playback on camera
Decrease BWL 30% = record 8 sec and 1 sec playback on camera
Conclusion, BWL has no effect on recording

Test CBR begining settings ( CBR, 0.1X, OFF, 20, 90%)
Increase CBR 0.1 = record unlimited time and 1 sec playback on camera
Increase CBR 0.2 = record 15 sec and ERR 70 shut off
Increase CBR 1.4 = record 5 sec and 1 sec playback on camera
Increase CBR 2 = record 3 sec and 3 sec playback on camera
Increase CBR 3 = record 1 sec and no playback on camera - Camera locks up when trying to play
Increase CBR 4 to 9 = record 1 sec and 1 sec playback on camera
Increase CBR 10 = record 1 sec and no playback on camera
Increase CBR 11 to 20 = record 1 sec and 1 sec playback on camera
Conclusion: longest recording at cbr=1, longest playback at cbr=2

Tomorrow I will try to do some recording in the afternoon and to look at video

The old zoom button shares the same code with lots of other things (M-Fn, back wheel, lock, DOF and so on). So... lots of false triggers.

I noticed on 7D the Magic Zoom is enabled by other options like the shutter button.  Will these options be standarized?  I like the shutter option.  Also like the focus ring but it does not work yet on 5D3.

Thanks
#1397
I know that Canon switched the zoom button to the left but..  It would seem convienient to me if MAGIC ZOOM could be enabled by the old zoom button on the right, it is easier to use because my left hand is doing the manual focus and not conveniently available to press the canon zoom button.

i could prepare a special version that only adds bitrate (errh, nitrate), but this would be for a small number or persons only.

I would definetly try it!  Could you enable HDR video if its working also?
#1399
Wow!  That looks really good.  Does it run on Windows?  I think you should put a link on the User Guide, just like you did for the HDR video. 

I also hope to work on the raw image process for timelapse some day when I get this fishy video stuff working and then I will also hope you can add a link to your masterpiece in the ML User Guide.  All of this stuff really adds so much value to all the (amazing!) ML work you are doing.

So thanks for all the great work to all of the ML TEAM!  I am learning and improving my skills so much since I downloaded ML for 7D and 5DIII.

It's pointless, you can defish in post-production with much better results

I have been reading about Avisynth but there is no straight forward solution.  Learning curve seems pretty steep. 

Maybe Alex has develoved a zip package with all the goodies and scripts to do the math..  I love the stuff he did for  HDR video, it is really amazing and it took me a few days of work to be albe to do the same on Vegas Pro 12!  My hat off to Alex and his knowledge of scripting and the software packages required to do the work.
