Magic Lantern Firmware

Hey Alex, just wanted to say thanks for your great work on magic lantern thus far, but I have to ask when will T3i audio features will be fixed?
 
Sorry, can't give a timeframe on this. Could be anywhere between a few weeks and a few years.

Does A1ex now have a t3i to experiment with?
Last I heard, the audio chip was entirely different than the 60D and T2i, which is why the ML audio features weren't supported. And A1ex didn't even have one to experiment with, so chances were pretty slim that it would be supported anytime soon.

Meanwhile, as more cameras come out, they will likely also use this newer audio chip. Sooner or later A1ex or somebody else will have to tackle it, and the T3i will likely be suddenly compatible as well.
 
I wonder what audio chipset the new 1Dx uses? If its the same as the T3i's, I think this is a road we'll have to go down eventually.
 
I was completely leaning towards the T3i, but now you all have me a tad frightened. I've been borrowing a friend's T2i w/ML for over a month now and have come to rely on the on screen audio meters quite a bit. That being said, I really can't see myself buying a T2i because of the overheating problems I experienced and lack of articulating screen(huge in my book). I suppose it comes down to really wanting the 3x zoom so badly that I am willing to sacrifice audio meters...any suggestions?
 
Audio meters work on T3i, but that's all.

Canon's volume control is digital in 5D2 and 60D, which means you can't adjust volume at all (it's fixed). Not sure if it's the same in T3i, but I believe it is.

In 5D2, Canon's manual audio fixes analog gain at +31 dB (original finding by Trammell).

Digital audio gain is something you should always keep at zero (unless you have an extremely good reason not to do this).

What overheating? I shoot under the African sun and have never had an overheating issue with my t2i.

It *CAN* happen, but in my experience it happens less with the T2i than other cameras (like, say, the 7D). But I would have to guess that whatever conditions made it happen to the T2i would also cause it on the T3i, Zxander34.
Either way, this discussion should stay outside of this already bloated thread. I've personally written off the T3i for now because ML's precise audio control is a staple to my workflow (especially audio monitoring). I'd strongly recommend the 60D over the T3i.
 
[FONT=&quot]Hi.Small thing I have noticed with the latest one (oct27)on 550D. Movie mode while trying to adjust the ISO, while increasing/decreasing it, the ML value no. is not moving at all, it stays at a certain value. [/FONT] Also the beep while recording start/stop, is no longer? it was a nice feature.

I went back to oct18, it is working fine all the above issues.
 
Currious if anyone has tried to max out the bit rate on their setups and what does it look like? I was trying some tests today with my T3i and was able to get 89-97mbps with a 2.1x bit rate with audio recording disabled.

First off even my i7 machine can't handle playing it back smoothly :)

Secondly, I can't really see much if any difference.

Where does a higher bit rate become evident. What types of conditions does it really help with?

Cheers,
Pete

Usually scenes with a great deal of motion (fast action) or intricate moving details get lost in compression artifacts on lower bitrates. However, those are also examples of things that should normally be avoided with a Canon DSLR due to rolling shutter and moire, so the benefits of pushing it that high are arguable.
 
I played around with the 80-95 mbps clips this weekend and to be honest it seems to give a more stuttery feel to the video image when there is alot of motion in the frame. Almost like using too high a shutter speed. In the end of the day when I bring it back to 16mbps BD, it doesn't seem to hold any advantage and just doubles the file sizes.

Currious if the ultra high bit rate video of the hacked GH2's is similar.

Until we get 10bit color and / or 1080-60p it seems the higher bit rate is lost on other issues.

Thanks for the suggestion!

Cheers,
Pete
 
Has anybody else had any experience with pushing the bitrate as high as it can go? I was looking at getting a new sandisk extreme pro 95 mb/s card...the highest i've been able to go with my extreme 30 mb/s is 1.3x (still have moving stopping issues with movement)

Alex, any input on this? Thanks
