Although there are many topics on this subject, and since this is a frequently asked question on the forum, I tried to answer it for good:

Canon T5i ( 700D ) is a good camera, and many people try to use it these days for live streaming, as a "good webcam", using it´s HDMI output in capture cards ( Or canon software ) in OBS, Wirecast or these kind of softwares. The problem is that, like many other Canon DSLR cameras, it has a timer which turns off liveview automatically after 30 minutes, forcing a person to turn it on again and again, or pressing the half shutter button from time to time, which is annoying.

Magic Lantern is a software which once installed on canon cameras, give a wide range of new characteristics, and a friend from the ML forum wrote a code which prevent T5i from turning off automatically liveview after 30 minutes. This fix is called "Lua Fix", and it´s located on the Magic Lantern website, on the top of the page -> Downloads -> Download (dropdown menu) -> Experiments -> Lookup "lua_fix build" for T5i. It works only with the firmware 1.5.1.

Since my firmware was old, and I already use ML, I had to remove ML and do a firmware upgrade to 1.5.1 in order to install this new ML build.

Here´s the links for what you need:

Link for Canon T5i firmware 1.5.1 -
Link for Lua Fix Build for T5i -


Since I already solved, here´s how I did:

- I downloaded firmware 1.5.1 from ML website and unzipped the content into a folder
- I Made a backup of my camera´s card ( With the old ML content in any case... )
- Using a completely charged battery, I uninstalled ML from camera, using the method explained in the guide, where you access on camera´s menu "firmware update" and removed ML ( Read the guide for more instructions ).
- I low format the card in order to remove any trace of old ML files.
- Removed the card from the camera and inserted on a card reader on the computer
- Copied the new firmware file to the card´s root directory
- Put the card on camera and went to the firmware update and updated to latest version 1.5.1
- I low format the card again in order to remove the newly copied firmware file.
- Turned off the camera and carried the card again to the computer
- Copied the content of the folder with the new "Lua Fix" build to the root directory of the card.
- Put the card on camera again and went to upgrade firmware and so, installed the new ML build.
- Restart the camera and went to the Prefs tab -> Powersave in Liveview -> 30-minutes timer set to "Disable"
- That´s all. Now, my T5i no longer turns off automatically in liveview mode after 30 minutes.

Well, I hope this may save much time for other people !

All the best,

Dihelson Mendonça

Rename ML folder to ML.nb and autoexec.bin to autoexec.bin.nb. Copy extracted experimental build files to card. Overwrite ML-Setup.fir or not, it doesn't matter at all.
Insert card and power on cam.

Thank you, Walter. I already solved, and made a FAQ about it in order to help other people.

Here´s the link:

My Canon T5i runs firmware 1.1.4 and I have ML installed. Everything is fine, unless by the fact that it shuts down live view
after 30 minutes. This is annoying. Reading some posts, I knew that there´s a new ML experiment ( Lua fixed ) which can fix that, but it needs firmware 1.1.5 ( so it seems ). I fear brick my camera. I don´t know the correct steps I need:

- Upgrade firmware first ?? ( If I do that, the current installed Magic Lantern will still work, since it is designed to an old firmware, and camera will boot ? )

- What are the correct steps on doing this upgrade, please ?

Thank you.

Top of page -> Downloads -> Download (dropdown menu) -> Experiments -> Lookup lua_fix build for your cam and copy it to your card.
Then access Prefs tab -> Powersave in Liveview -> 30-minutes timer Disable

Thank you Walter. I located the file and downloaded. But my T5i already has a version of ML installed. Should I uninstall it first, or can I format the card on camera and put the new files as if there was no ML before ? Thanks for pointing me to the right place.

Hey A1ex, I tested that build and it works great!  I had the camera outputting 1080P HDMI for 8 hours straight.  No shut downs or anything, the other systems worked fine.  Global draw off etc.

So basically got the full clean HDMI output from the 700D/T5i for 8 hours.  I didnt test any of the other functions, photos etc.  But for this function it was fantastic and no faults to report.

So thank you for the work and keeping it moving, I now have a functioning camera!

Hello, friends. I think it worths replying to the topic, because it´s a continuation of the starting question I did.

AeroSimGaming, I read that you somehow installed the "nightly build" or the Lua script on your T5i and solved the problem with it automatically turning off live view after 30 minutes. I also use my several T5i to film long events, and as an excellent "webcam" for broadcast through OBS, but since it turns off live view after 30 minutes, it becomes impactical. I searched for many years a solution to this problem, since Magic Lantern ( That I know ) couldn´t find where the sticky half shutter function on this camera, so, when I saw that A1ex posted here on my topic thay he made a script, I became very interested. The problem is that I know NOTHING about Lua scripts, or how to use them, but at this time, may be this script could have been incorporated on a nightly build, but what ? I still use an old Magic Lantern version, and I fear testing not stable versions on my cameras, but since you tested and it worked fine, could you please tell me all the steps to overcome this problem ?

Thanks in advance !

Hello, fellows,

After many months, more than a year away from the forum, I came back to know if there´s yet any advancement, or any idea on how to prevent Canon T5i to stop liveview automatically after 30 minutes. I use these cameras for live broadcasts, using the  HDMI output, but having to turn on the cameras every 30 minutes is like a fellow once said "Ain´t that a kick in the head"...So, any tips on how preventing it from doing so in 2017 ?

Thanks in advance.


Your solution really came to me ! I use my 700D cameras for streaming to youtube and this is a nasty problem, since the guys didn´t find a solution. Your Sparkocam solution is indeed interesting, and I will try and post the results later. Thank you for sharing this nice and useful tip with us.

Hello, Walter Schulz:

"1: No. Go to and download firmware 1.1.4.
2: RAW/MLV: Continuous recording.
H.264: You will loose some frames at 29:59.
Or use external HDMI recorder"

Hello, Walter, how are you ? It´s been a long time since I used my cameras along with Magic Lantern.I have some Canon 700D which are still using firmware 1.1.3. Reading your reply sbove, raised some questions:

01 - With firmware 1,1,3 will I have RAW/MLV continuous recording ?
02 - I intend to use my camera with an external HDMI recorder, or cpture card. Indeed, I used some time ago, but the problem is that it shuts down at 30 minutes or so. This "continuous recording" you mentioned can be used to record not internaly, but externaly through HDMI without interruption ? At 1080p on output ? using firmware 1.1.3 ? In order to upgrade my firmware to 1.1.4, should I uninstall Magic lantern first, format the card, upgrade firmware to 1.1.4 and so, make a fresh instalation of the latest Magic Lantern ?

Thank you in advance !


Hi, Robsi, this is great news. I needed to read this from a person who just use it for years. So, we have the proof now that there´s no problem to the sensor on a long term.



I use a battery grip on my 5D Mark II, and it never shut down too. May be due to the battery grip, which works as a heat sink.

Walter, there´s a doubt. I saw in some place that when updating to a new nightly build from an old ML release, we wouldn´t need ( or shouldn´t ) copy the file .FIR which comes with the new nightly build to the card. Is that true ?

Hello, Paul,

Yes, we can shoot on T3i or T5i for more than 1 hour, or 2, 3...I´ve made some long recordings too, and yes, the sensor becomes hot, but it keeps recording. We only need to know if this is safe on a long run, or if by doing this, aren´t we abusing the camera, perhaps prone to hot pixels, or making the sensor die faster than using for photography due to high temperatures. We will not have an answer to this question unless people who use it frequently for long time recordings could add some information. I´m researching and consulting broadcasters on youtube that uses DSLR for continuous video recording, since it´s a tendency now to use DSLR for broadcast live events in churches, concerts, etc, since youtube and now Facebook made it possible. There´s dozens of services competing on this new market. The main software used is called wirecast. It can broadcast to Facebook, Youtube, and many others in realtime, and people all over the world watch. I see in the future, most people having his(her ) own TV channel. There´s already many of them ( in realtime ) on youtube. And they are using DSLR instead of video cameras ( which is expensive ) or webcams ( bad image ) for these broadcasts due to the high quality a DSLR can deliver. Thanks for comment.


No problem, Paul. No offence taken.

All the best to you.


Hi, Axelcine,

Thanks for the information. I confirm everything you said about "HDMI out is what you have on the screen". When in preview, I have great resolution, but if I press the record button, resolution goes down, this is a characteristic. I confirm that the signal is really interlaced, since in one experiment, I input video to an Avermedia card which supports only 1080i and it works nice, but when I input to a Blackmagic card which we need to choose resolution first, all of them failed ( 1080p, etc ) ( black screen ), but 1080i 59fps works fine. Thanks for the insights and replies on this question. I see you have great knowledge on DSLRs which I hope you share with us, mostly these parts related to the HDMI output, which I still have some little doubts.

Hello, Axelcine, are you sure you replied on the right post ?
What HDMI hardware are you talking about ? I never mentioned here what ML versions I use. On 700D, which I reffer on this topic, I use the latest nightly build version and this topic is about my experiences trying to remove the letterbox HDMI output from the 700D. Many people currently use DSLR canon cameras for live streaming to the internet, as you can see:

- DSLR for Wirecast - Part 1
- DSLR Cameras for Broadcasting with Wirecast
- Facebook Livestream From Desktop & DSLR
- Connecting a Camera Directly to Your Wirecast Computer
- Using Canon cameras as a webcam

Live broadcast is the new fever...


Since there´s 210 people seeing this topic, I imagine that they want to know the answer too. At least for now, I could find, regarding the question, that with ML, you can remove top and bottom black bars, but not the left and right ones.  DSLR sensor is 3:2 aspect ratio, not 16:9, so, if you use Magic Lantern, you can use parameter remove overlays to "Always" and this will output a 3:2 video through HDMI directly from the whole sensor. In order to get 16:9 aspect, you have to crop. Using softwares like Wirecast for instance, you can crop using the crop and zoom function. Obviously, it won´t be 1920 x 1080 nor 1280 x 720, but something in between, but will be very good and HD. So, for people interested, that´s what I´ve found till now. All the best.

I appreciate that !


I don´t understand why you don´t use an USB cable for transfer your images to the computer. I never never detached my card from my camera in 5 years and I took photos and videos frequently.

Hello, guys,

There´s an old topic here on ML forum about how to record video for more than 30 minutes, but since the topic is more than 120 days old, the forum suggests that I create a new topic if want to comment, so here we are...

Some people talking about how to get more than 30 minutes videos on Canon cameras, when a person suggested getting an external recorder named "Atomos Ninja" for recording through HDMI output, instead of using the own camera with the limitations we all know ( 30 minutes ). Well, my two cents to this question: You don´t need to rent or purchase an expensive Atomos Ninja to do the task. You only need a laptop or a desktop PC ( which I think most of us already have ), and a USB capture card, like Blackmagic Intensity Shuttle ( There´s two versions, one USB and another Thunderbolt for Mac users ). So, you use your Canon cameras with Magic Latern to remove all overlays on the HDMI output. On Magic Lantern, set to remove overlays on the "Always" position. Then, connect your camera to the USB capture card using a mini HDMI to HDMI cable. Then, connect your capture card to a USB 3.0 port on the computer. Use a capture software, like the one which comes with the capture card. Use ML to remove the 30 minutes auto live vew shut down, by enabling the parameter "sticky halfshutter" located on the MISC tab ( unfortunately, Canon T5i ( 700D ) doesn´t support it yet, but most cameras support. That´s it! Now, you can record video with no limits on most Canon cameras. You can capture sound through an external device like a small Tascam DR-05 or a Zoom H1 audio recorder and merge on any video editor later.

The advantages:

01 - You won´t have any gap by using canon cameras and ML starting the recording over and over.
02 - The cost is minimal because you´re using what you already have.
03 - Image quality is incredible !
04 - You can use this for live streaming to youtube, Facebook and all systems with the greatest possible quality and a minimum price.

The disavantages:

01 - More equipment to transport, but if you need it for churches, shows, live events, this isn´t a problem.
02 - You need to acquire an external capture card like Blackmagic Intensity Shuttle, but it´s not expensive.

That´s it !

But there´s the real matter of sensor temperatures, no ? We always heard of the import duty...yes! Canon, Sony, Panasonic don´t want to close their movie cameras department because people are using DSLR for it, BUT...will sensors support temperatures ? My 5D Mark II gets very hot while in Live view for long time. I don´t know for sure if it will support or will have a short lifespan due to it. It would be interesting if more people which uses DSLR for streaming through HDMI or use a lot of live view could make their points here, but I don´t know where to find them...

Hello, Micinaro, can you post a picture of the problem ?

Well, after almost a week, nobody answered to my question. Although with Magic Lantern I could remove all overlays and even those top and bottom black bars, I could not remove the left and right black bars from the live view of my 700D. If I don´t find a way to fill all screen, I would have to crop image to a 16:9 format, which I will lose resolution. I use it most for live streaming through HDMI output. Capture softwares like Wirecast recognize this output with black bars on the left and right sides.


Is there such thing for 5D Mark II also ? I´m using mine for streaming videos, but I need to control, and while streaming, I have no control over the camera independently...
