Auto-Beroflex vs Yashica ML @2.8 28mm - Canon EOS-M (MagicLantern)
Shutter speed 1/50 - ISO160 - 25fps - ND filters
Very interesting!
What were your ML settings?
Can you post pictures of how you mounted the lenses?
Thanks!
ML settings : 1/50 - ISO160 - 25fps - ND4+ND8 filters

Thank you for the helpful links. The EOS-M is highly versatile in regards to attachable lenses/adapters.
Can you be a little more specific about your ML settings -- which build, shooting raw, MLV or h264, resolution, crop mode, GOP setting, etc.
Thanks!
ML build - tragiclantern-v2.3.NEXT.2014Jan20.EOSM202 - http://tl.bot-fly.com/ (http://tl.bot-fly.com/)
BitRate (CBR) - up to 2.0X
Video - h.264
Picture Style - UserDef1 - 0,-2,-2,0
Zebras , FocusPeak , MagicZoom - ON
LV DIGIC peacking
Shoot in M mode
That s all .... i think :D
I appreciate the great info!
I am considering getting an EOS-M, but here is the important question: In that Tragic Lantern build for the EOS-M, can one set the GOP to "1" or is there no GOP control?
Thanks!
If i enable Video Hacks i got :
-Flush rate 4 frames
- GOP size 12 frames
Very helpful info.
Interframe h264 compression is the killer. When every frame is its own image (GOP 1) the video looks cleaner. Also, it helps to minimize the the h264 intraframe artifacts by boosting the bit rate (and tweaking d-block settings).
When you get a chance, could you try setting the GOP to "1" with the bitrate set to "2" or "2.5?" Such settings probably require a fast SD card to work for any decent length of time.
If the EOS-M works continuously with such boosted bit rate and with the GOP set to "1" then I am buying one!
Thank you!
It works at GOP 1 and CBR up to 2.0x but the sound is disabled .
I`ll do a longer test outside ...
My card is a Samsung 32GB http://www.newegg.com/Product/Product.aspx?Item=9SIA12K0PT8070 (http://www.newegg.com/Product/Product.aspx?Item=9SIA12K0PT8070)
Great!
If you were able to shoot for more than 5 minutes at those settings, I'm sold. Sound is not necessary for my purposes (I have a separate system for that).
Thanks!
Here is a shot of 7:41 min and i could record for 30min for sure - https://mega.co.nz/#!PBAGSADA!0qpCriyL-xSS8z91d-FifpMPbqjvQo3zlmBpotTBeMk (i think my AWB is offfff)

the GOP is 12 and there is sound !!!!
hope these helps ....
Thank you trying these settings and for posting all of this information! It is very helpful.
It is interesting that the video with the enabled hacks has a bit rate that is 1/2 that of the video with the hacks disabled. Perhaps the short duration of the disabled hack video is responsible for this apparent discrepancy.
Also interesting is that the video with the enabled hacks shows a variable bit rate, while the disabled hacks video shows a constant bit rate.
Was the CBR set to 2.5x in both videos?
I'll try to download the linked file.
Thanks!
the CBR was 2.5x in both

yes ... i saw that too after inspecting the info from MPC ... i don t think the short duration is responsible for the bitrate ... mby my slow card ? ...
Look at QP per frame and what kinds of frames they are.
i did 2 test with Video hacks enable and 2.5x CBR

in the first video the GOP was set to 1 and in the second the GOP was 12 (default)
the diferences in the bitrate are big .... i ll do more tests :D

Thank you for posting these videos. I would love to see them, but, unfortunately, I am unable to get anything off of that www.mega.co.nz site. YouTube or Vimeo always works (I can deal with the site compression).

What's QP?
In regards to the kinds of frames, the video with GOP 1 should be all "I-frames," correct? The GOP 12 video should contain one "I-frame" for every combination of eleven "P-frames" and "B-frames," right?
Isn't compressing a video into combination of "I,"P" and "B" frames supposed to use fewer bits than all "I" frames?
Video hacks enabled - GOP 1
(cut from the 7 min clip)
Video hacks enabled - GOP 12
color corrected ....
can u download from here ?
GOP 1 - https://drive.google.com/file/d/0B7AZlxgW5DjtSTZJVDl3QWhNZUU/edit?usp=sharing
GOP 12 - https://drive.google.com/file/d/0B7AZlxgW5DjtQ0ctcGNHNzJmNDQ/edit?usp=sharing
I can download the drive.google.com links. Thanks!
Both videos look pretty good. Still wondering why the bitrate seems peculiarly higher on the GOP 12 shot.
Appreciate all your efforts! Because of these videos, I'll probably get an EOS-M along with several cheap Ebay lenses/adapters (maybe even the Yashica -- it seems fairly sharp and snappy).
Thanks!
I'm glad I could help !!!
Bought an EOS-M from Amazon today. The Amazon page said only one remained in stock. Of course, immediately after I ordered it, the page said more were available.
At any rate, I am looking forward to using it with the settings discussed and with some interesting lenses.
Thanks!
