Don't take photos while shooting. It can make a 3 frame drop-out in the video. Maybe it resets the audio IC too. I have 0 problems if I take a photo after or before a video in remapped movie mode. Also a big 20MB drop into a completely different code path, at least for raw.

OK
By "remapped movie mode" you mean video mode with Magic Lantern ?

No, I mean movie mode remapped to A-Dep. I kept that.

Mister Paul · « **Reply #253 on:** September 30, 2012, 07:09:50 PM »

I am sorry but I still don't understand…
Is there a tutorial where I can clear my mind about it without bothering you here asking questions?

Not really, this stuff is fresh out of the oven.

Just don't take pics while recording, you'll be ok.

Playback isn't set up to work through headphones.
Would be great to control taken shots!

Everything seems to be fine with audio/600d now - but I agree ... it would be good if we could hear and check what we recorded. Actualy this is very important.
Thanks for your great work so far - I´ll donate again soon!

You can play back with the sound recorder but its through speakers.

Anyone else getting tearing at high bit rates with stereo wav?

Miyake's original autoexecs were mono, mine are stereo. Maybe buffer too small? Card too slow? Some other error?

Yea, its gone.

Until next ML release.

https://bitbucket.org/OtherOnePercent/tragic-lantern/downloads

But need to have card formatted to exfat.

So If I wanted to test out the audio features for 600d, I could:
1) Download your tragic-lantern build onto an exfat card (any side effects of exfat?)
2) Is it possible to try one of the nightly builds from a1ex since the source got merged into his repository
3) Wait until the next official release (which should be coming....when? not trying to ask for a date or anything, I know that's ridiculous, I'm more curious about a general timeline, like before or after the new year)

Thanks again for all the hard work on the 600d audio side of things.

Do 1 or 2. Only side effect of exfat is files over 4gb work.

Hi,

This is my first post on this forum. I have a 600D and I've been using "Tragic Lantern" (if I may call it like that) for a few weeks and I've been doing a little test last night with different settings. With audio off, I've been able to achieve an average 130mbps while recording a city map, with a lot of details in it. The BR peak was around 160mbps. No problems of stability.

I've used different settings to try and see wich ones would give be the highest BR, and here's the result, finally, I ended up with theses settings :

CBR mode ALL I GOP 1

GOP factor 0 and 1 at 3.0x
GOP factor 3 and 4 at 0.1x
D1 and D2 factor at 0.1x (what exactly is this setting ? It seems that it doesn't influence BR much...)
JP Slice at 87 and locked
Min BR : 80
Max BR : 200
DblockA - 6
DblockB -6
PicPC -7
Buffer Warn 70%

ISO was 320, and audio was off. My SDHC card are Sandisk Extreme (45MB/s) and Extreme Pro (95MB/s) and both worked.

I don't know if this would be any help, but I figured "you never know"... I used the "422exmem" released. (at first I thought I would be able to record in 422 but I guess I'll to wait for mjpeg encoding if I understand this right ?)

I don't exactly understand what all those settings do, except I think for GOP and Slice, so would you be able to post quickly a little "what's what" about all the settings, like D1,D1, DblockA... Because I don't know if the BR or the encoding quality should be better with lower or higher values...

Thank you for all this amazing work, I think you are just creating, with your work on the 600d, the better HDSLR on the market, even if it's not a full frame.

Slice 87 is max quality. If you set it to only 87 you will be max quality all the time. Some scenes will let you record like that and get theoretical max bit rate for camera.

Gop + all X stuff is for the CBR without cache hacks function.

Min max are to drop slice if buffer is getting overflowed.

I need to write a doc or something.

ilguercio · « **Reply #261 on:** October 28, 2012, 11:30:08 PM »

Are you, or Alex, going to port this on other cameras too?
I know there's the problem of cache hacks but i think i wanna risk it for the sake of science

1% · « **Reply #262 on:** October 28, 2012, 11:40:20 PM »

Well 7d is getting done. Look in FW for the locations of where you need to cache hack.

ilguercio · « **Reply #263 on:** October 28, 2012, 11:45:51 PM »

Well, i just started understanding ML code and refreshing my C studies.
I have Ubuntu in dual boot on my system, so i probably have to run ARM console to do some work, right?

juantrueno · « **Reply #264 on:** October 28, 2012, 11:46:41 PM »

I know that you maybe already talk about this, but where can I find the latest ML 2.3 with audio controls and exfat for 600D? What's new on it? Thanks

1% · « **Reply #265 on:** October 28, 2012, 11:53:19 PM »

Yep, the disassembly takes a few days. Both nightly builds of 2.3 and builds in my repo have 600D audio.

juantrueno · « **Reply #266 on:** October 28, 2012, 11:56:06 PM »

Should I wait for next relase? Can I use one of yours? How is it named?

1% · « **Reply #267 on:** October 29, 2012, 01:28:36 AM »

There is a 550D build that lets you change gop, its postfixed 550D. But not up to date.

C.films · « **Reply #268 on:** November 18, 2012, 01:17:35 AM »

So how exactly do I install this into my T3i? Just download the lastest, throw it into my SD card, and turn on the camera? Or is there a specific way I need to install this?

a1ex · « **Reply #269 on:** November 18, 2012, 10:17:43 AM »

Experimental versions are for advanced users, who can read the install guide. For something that works out of the box, wait for a stable release.

See http://www.magiclantern.fm/forum/index.php?topic=3072.0

sparkplug · « **Reply #270 on:** November 18, 2012, 06:27:21 PM »

I've installed the latest nightly build on my canon t3i and it's working just fine, but there is one thing that bothers me. There is this overlay in the center of the screen that reads out +, out -, vol+ and vol - . And in conjunction you can adjust those settings with the arrow or navigation buttons on the right side of the camera. That's a pretty ingenious addition, but I use an external system to control the audio and I'd prefer to turn this function off, but I can't figure out how. Is there a setting in the menu I'm missing?

1% · « **Reply #271 on:** November 18, 2012, 07:12:30 PM »

Its in prefs arrow/set shortcuts.

Robbe · « **Reply #272 on:** November 22, 2012, 02:23:43 AM »

What's the purpose and difference with out +, out - and vol+ and vol-?
And to connect headphones - is the way via Canon A/V cable?

PS
And once again; impressed by your work and hope Canon realizes it too!

scrax · « **Reply #273 on:** November 22, 2012, 07:45:38 PM »

vol + is more volume
vol - is less volume
out + monitor vol
out - monitor vol

Robbe · « **Reply #274 on:** November 23, 2012, 12:01:05 AM »

What is next and previous Out line?
