[DONE] Movie Restart on 5D3?

[nigelbb]

I have been using the Alpha 3 build of ML for months but finally got around to trying a more bleeding edge version to whit the August 2nd Nightly Build with RAW video etc. I was excited to see that an option for Movie Restart is available under the Movie Tweaks menu. However this doesn't appear to be working. Is this deliberate? I recall some discussion when ML was ported to the 5D3 that this was omitted (for reasons that didn't make sense to me). If there has been a policy decision to omit this code from the 5D3 Nightly Build is it possible for me to take the source code & build it myself with the Movie Restart function? I was a software engineer in a former life so this would be a viable option for me. ALternatively is this just a bug in that Nightly Build?

TBH, I never had the patience to wait for half an hour to see if it really works.

I was shooting a wedding last Friday with ML on two 5D3s. Movie Restart was On but during the ceremony both stopped at 29'59". I really just wanted to know if it is supposed to work. I was assuming that it should be working otherwise what is the point in having the setup menu option? If failure to restart is a bug then I'd like to notify it as such so perhaps someone will take a look at fixing it.

I used it once back in March.  It worked then.

I also just upgraded to a new version of Magic Lantern and was very excited to see the 'Movie Restart' option had been added!

I've just tested it on both my 5D3s and unfortunately it's not working on either of them

I use them to film events, so often rig them in unreachable places - it would be such a useful function to have. Not to have to worry about having to restart the cameras.

Hopefully if it worked for Audionut back in March then it means it might be possible to get it working...

Thanks,

Simon

Was this definitely on the 5D3? Movie Restart was deliberately omitted from the Alpha 3 version of ML released last December. It seems that we now only get Nightly Builds with no attempt to freeze features & debug a definitive version. I know that this RAW video & Dual ISO stuff is really exiting for the developers but for those of us using the 5D3 for paid event work having Movie Restart would be far more useful. The current versions are more polished but I would be perfectly happy just to have only the features in the Alpha 3 version with Movie Restart added. Zebras, peaking & extra Info display like GB free on card is such an improvement over stock firmware that it keeps me happy enough but knowing that Movie Restart is possible & was working is very frustrating.

[Audionut]

Turns out I mistook 4GB file splitting for movie restart.

Sorry to get your hopes up.

[nigelbb]

What needs to be done to get this working?

[nigelbb]

I have posted a couple of times in the General Development forum regarding this issue without getting an answer so perhaps it will get more visibility if I post here. Perhaps someone could even be incentivised to fix it.

Move Restart does not work on any of the 5D3 builds that I have tried including most recent Nightly Builds even though there is a Magic Lantern menu item to enable this function.

According to this webpage which is a Feature Comparison Matrix http://nanomad.magiclantern.fm/jenkins/features.html "This table was generated automatically from ML source code. It only shows what things are enabled - they may work or they may not." Movie Restart on the 5D3 is not enabled. I had wondered whether this was because the 5D3 recording limit is fixed by Canon firmware at 29'59" rather than the single 4GB file of the 5D2 & other older DSLRs on which Movie Restart does work. However according to that matrix Movie Restart is enabled for the 6D, 700D & EOS-M all of which have a 29'59" limit so span multiple 4GB files for one video clip.

Perhaps someone using Magic Lantern on the 6D, 700D & EOS-M could confirm whether Movie Restart indeed does work on these cameras.

I recall reading somewhere that Movie Restart was deliberately omitted from the Alpha 3 version of ML released last December but am not sure if this is still the case. Can anybody who is familiar with the source code answer the simple question of whether Movie Restart could be enabled on the 5D3?

This would be such a useful feature for those of us who use the 5D3 for weddings & other events. I typically have one or two locked off B/C cameras while I shoot the main action on a 5D3. Ideally I would use another 5D3 or two as the wide angle locked off 'safety' shot so that I get a consistent look between all the cameras. The regular 29'59" limit is OK most of the time but too often a ceremony of the speeches will just run over & I would be losing the last few minutes & because of that I cannot use the 5D3. I have been using a proper camcorder (Canon XF105) but this isn't so great in low light. I have just switched to a Panasonic G6 which doesn't have a recording limit but is MFT so it looks a bit more 'videoy' & the colours don't quite match up like they would if I were just using another 5D3. If Movie Restart really does work on the 6D that might be an option but while the 6D has the low light capability of the 5D3 it also has the moire & aliasing of the 5D2. So I really really want this to work on the 5D3.

I got no reply to my questions but almost instantly I did get a PM warning me about double posting. I tried to reply to the PM but cannot. So will reply here instead.

I realised after posting on the General Development sub-forum that Feature Requests was a more appropriate sub-forum so then wrote a new & expanded post on this sub-forum. If I could have deleted my original post I would have done but there is no option that I can find that allows a user to delete a thread once started although presumably the moderators can do this. So please instead of issuing warnings why not just engage in dialogue? Perhaps the moderator who sent me the PM could delete the thread from General Development & leave this thread in Feature Requests? If I could have done it myself I would have & it's not really my fault if the forum software does not allow basic functionality to the user like deleting a thread that they realise is in the wrong sub-forum. I also didn't just cut & paste the same post in both as in the Feature Requests sub-forum I expanded on my original post & have spent some time describing why this feature is important to me & others.

Cheers

There's no such menu on my 5D3.

I have absolutely no use for movie restart, so I'm not going to fix it (especially since a single testing attempt is going to take half an hour). But if anyone else wants to take a look it, nobody is stopping him.

I have no idea if it's actually working on any other DIGIC V camera. There are probably many other things enabled and not working, because very few people actually use them, and the maintainers of these cameras did not try them before publishing the binaries (it would probably take days or weeks just to try every single thing from the menu). I'm actually thinking to implement a feedback form to identify what's working and what not.

And yeah, opening 3 threads on the same subject is not welcome.

I cant help but think the dslr movement leans way more to the needs of indy film makers and not so much for event coverage or reality coverage. If you need to shoot for longer then 20mins you shouldnt be using a dslr. i just dont see the point. get a video camera not a still camera right? or have 2 shooter and give each other signals notifying one another when your reaching your limit. or just cut wisely as you will most likely be cutting and chopping up in post right. I used to shoot weddings and even when i shot the ceremony i found plenty of time to cut and move. When i had my hmc 150 i used to film the whole ceremony and not one of my clients said they watched the ceremony all the way through. they just skipped to the good stuff. so i stopped and just presented the highlights of the ceremony with other clips of fam ect mixed in. Also it clearly says over and over that ML alphas should not be used for paid production work. tho i find it to be more stable then my gopro firmware which freezes all the time. just my thoughts.

[bricriu]

I have tons of use for the movie restart option and was sad to see it's not working on the 5D3. I think one of the main fields that require shooting events on a DSLR is wedding videography. Wedding videographers typically assemble a short artsy highlight video, which is why we need the amazing quality dslrs offer, but then we also need to make sure the entire event is being recorded from start to finish so the couple can watch it later.

Last I checked worked on 6D and nobody has complained about EOSM so I guess its working on digic V if the dialog is correct in stubs. Will have to double check while plugged in.

Just a thought, because I'm stuck with this bootflag in my cam for now anyway...

I will pay the developer who gets restart working on the 5D3 $100 via PayPal.  I may not ever use it but I want the capability if I need it some day.  It would need to be seamless though, as having dropped frames wouldn't be good.

For the test, just set it on a tripod watching a TV, it would be easy to check for smooth transition that way.

I will also pay the developer who comes up with a safe way to remove the 5D3 bootflag to the masses- $200 via paypal

My offer is until December 1st

Thanks

Would love to have this feature working as I film weddings and it's really helpful for Ceremony's, theres more that once where I have forgotten to press record again.

I don't mind testing it on my 5D MK3 if a dev comes out with a fix, as long as my camera won't explode of course

[VisualPursuit]

Another one. Theater production filming for DVDs. One camera straight onto
the stage for general overview and safety shot that you can always return to.
Serves as master sync track as well.
With already five cameras around and manned, auto restart on this stage
overview camera would  be very welcomed as a feature. Saves one hand.

[strangey316]

Would love to have movie restart on the 5d3 also, willing to chip in $100 if such a fund is set up

Regardless, thanks to all at ML for everything they've done.

[strangey316]

Again let me preface this by saying that the work the all the Magic Lantern team have done is phenomenal, and I am very greatful for all the features they have given us (for free!)

Regrading movie restart....

Another workaround for this would be to have the intervalometer set up for video as well?

Correct me if I am wrong, but (unlike on the 60d/550d etc) the intervalometer function on Magic Lantern for 5d3 only works with stills.

If this was to be enabled so that you could interval record in video mode, you could, for example, set it up to:

Record 15 min video

stop for x seconds

Record 15 min video

and so on.

I've not idea if this is possible, but it would be a usable workaround for those wanting movie restart
(like me)

I shoot Opera and the movie restart feature would be very welcome, since operas usually go on for about 3 hours. I would do it myself if I knew how to code it.
Hope someone accept the challenge and help us out!

Hi A1ex,

I'll try and make the movie restart work on the 5D3. Just a question though: How do I find out why isn't it working? I thought of enabling it and get the dump from debug, but if it don't restart will it leave any marks?
Hope you can help us out.

[viniciusatique]

Great news guys! Fixed Movie Restart on the 5D3. Activated the feature on movie tweaks and by suggestion and with the help of our friend 1%, I changed the wrong NSTUB for the right one and voila! Tested on my 5D3 and it's working fine.
Can't seem to be able to commit it to the unified though. Cloned from unified/hudson to my mac but don't know how to send the changes in order for everyone to have it. 

[Audionut]

You can do it via web browser.

[viniciusatique]

Thanks Audionut! Will do that tonight

[viniciusatique]

Commited and pull request sent. Hopefully soon everyone will have the feature working on their 5D3s
