Since you are on the ML forum, I'm going to guess the 5D (upscaled to 4k?) because none of the other cameras use ML, but my other guesses would be GH4, Black Magic, maybe Sony A7s (in that order).

EDIT: Are you Luciano Frias?

When did the 5D mk iii drop so much in price? I thought it was round 5k?

I'm sure this has been asked billions of times by now, but could it be possible to use FRSP or a spin off of it, to get better quality full HD jpeg sequences at 24fps on something like a 600D? or is that just simply too processor intensive?

I own a Tascam DR-05 and I'll tell you that I love it, although some times I´m not 100% sure what I'm doing with it. I'd love to own this one, but unfortunately I have taxes to pay in a couple of of weeks.

Hardware and Accessories / Confusion by Nikon Lens...
« on: February 24, 2015, 07:52:40 PM »
I recently looked at a Nikon 35mm f1.8 LINK: http://www.bhphotovideo.com/c/product/606792-USA/Nikon_2183_AF_S_Nikkor_35mm_f_1_8G.html and it looks like a pretty solid lens for video, but I'm confused by the relatively moderate ratings that even the expenisve adapters get. I understand that this is a g mount, and it won't have AF (don't care about AF anyways, I'm doing video mostly). I've read things such as the mount causing a 1.54 crop factor (can't confirm this, anyone here can?) to loss of aperture stops, light leaks, etc... I know a good number of people here have the capacity to buy expensive equipment and don't consider anything less to be of value, but in my case I need balanced  options between quality and price. I guess I can sum up my question to, what lens mount adapter is suited for this lens that will work on a 600D?

     You are welcome Emphram! I'm still experimenting with Exfat, but from what I've read raw recording performs better. From what I've tested so far, I feel it is a great format. There is also an exfat option to choose in the Magic Lantern Nightly Builds menu, which I still need to test. I was able to record 1080p for 29:59 with continuous record. I still need to test 720p 60 fps because I would like to see if I can get to 29:59. I used to be only able to get around 15 minutes. I also haven't found the batteries to wear out, and last just as long as Fat32 formatting. If you are having trouble with missing a couple seconds in between takes, try adding a second camera. Even if it's a cell phone that can record HD, you can use that for just those couple seconds to switch between scenes in post if you are filming an event for example. Also, if you record audio to a separate recorder, you can maintain the same audio throughout, and just sync in post using Plural Eyes, Premiere Pro Creative Cloud, or manually. You can use the cell phone and dslr audio along with separate recorded audio to sync, and then choose what you feel sounds the best, probably the recorder.
     
     I love shooting raw! I'm still getting used to it, and am learning as much as I can about the post production workflow. My recommendation for getting the best resolution is to use a wide angle lens. Luckily I have a 6.5mm fisheye I use for skateboarding, and will be able to take out the distortion with a fisheye lens profile in Adobe Camera Raw. If you have the kit lens, try using it a 18mm, the widest, and see how you make out. This will help when filming events, say on a shoulder rig for less camera shake, and your kit lens might have an image stabilization option which will help as well. You can also zoom in as what's called crop mode. Some Magic Lantern users have claimed this gives better quality, but I find it a bit difficult to work with. When zooming in 5x, you can bump the resolution higher. Setting up the shot is kind of a pain, but this might work well with outside with flowers and insects. If doing macro, you can buy macro extension tubes from Fotodiox on Amazon as well. I would suggest trying different resolutions at different aspect ratios (2:35:1 rather than 16:9 gives a cinematic look, which is great) and see how long you can record. Also, turning off unneeded settings will help extend the record time. You can even try 18 fps or 12 fps to achieve longer record times, or even continuous recording for raw. Recording raw with sound can slow down the best possible resolution for raw recording, and even more with audio override settings. So keeping the sound on automatic helps, and then using say a Zoom H4n or H6 for separate recording to sync later. There are even cables from Sescom that will allow straight audio recording from the Zoom to the camera. There is a Transcend 64 gb Class 10 600x (90 mb/sec) sd card which is the same price as the Sandisk Extreme Pro 32 gb 95 mb/sec Class 10 sd card. I've read and discussed with someone that this works just as well as the Sandisk, and then you have double the space for the same price!

     If you want to record H.264, you can purchase a VAF TXI filter for the T3i. This helps prevents aliasing and moire from being recorded in your video, and also gives better compression, resulting in better quality. You can call Mosaic Engineering and ask them about their filters which have marks on them. They are fully functional, and do not prohibit best possible quality from the new ones. New, the filters run at $295. I spoke with one of the personnel about this.

     I hope this was helpful for you, and please let me know if I didn't explain things clear enough. Always here to help! Hope all is well!


The problem with raw that I have is the following:
Noise is a lot more visible (especially in low light, and I mostly work in low light, and have to use high iso, 1600, 2500).
Aliasing is alot more visible (anyone else have this problem? I think using it in 3x crop mode the problem goes away, but I can't use 3X crop all the time).
Chromatic abberation is a lot more visible (but easy to fix in adobe camera raw).
Still confused by workflow (mainly because of lack of progress).
Need to get farther away from subject to get same composition (I work in a lot of cramped spaces, sometimes it just isn't possible to get farther away from  the subject).
Lack of money to buy wider / faster lens (most lenses that would help improve my shots are not within my financial reach, I don't do video full time, my full time job is web dev and so far it's been supplying my turtle slow acquisition of equipment, skills and experience).

I'd much rather have the 650D or 700D for raw at 720p, that would be much easier to work with in POST, but again, not enough funds. I barely receieved a light kit today, I wish there were some online video work I could from here that would help me further my acquisition, but so far nothing has come my way.

I get the impression from the prices that these devices are over qualified for what I would be doing with them. I just want to hook up two mics to two people and a receiver to the camera. I can't see why they would cost nearly 2,000 dollars. As for legal bands, in Mexico nobody really cares, besides I don't need more than 10m range.

     Hello emphram my name is Paul Harwood. I formatted my Sandisk 32 GB Extreme Pro 95 MB/SEC Class 10 UHS as Exfat, with MacBoot for Macintosh, but I had difficulty getting the software on my Transcend 64 GB 30 MB/SEC card about a year ago. EOS Card should be able to format the card as Fat32 (I think this is what Canon uses). From what I read however, Exfat allows bigger file sizes. I always thought the limit was 4 GB, but there is a setting on the 600D for Exfat in raw mode. I still have to test everything out, and am also weary about long shoots like you stated. I think I used a smaller card to install Magic Lantern a year ago, the stable version 2.3, then dragged the files onto the 64 GB Transcend. This was because I couldn't get Macboot to work, but I'm pretty sure EOS works fine. I have since figured out Macboot. There is a tutorial by Clint Boland on Youtube explaining EOS Card on Youtube and the installation process. I hope this is helpful for you. If not, please let me know if you have any other questions. If I experience any problems with Exfat, I will post here. It would be great if you could do the same, that way we can exchange input, since we have the same camera.

     Here is the tutorial. I am aware this is for ML version 2.3, the stable release. After you've installed V2.3, all you have to do is replace the V2.3 files with the nightly build files, put the card back into your camera, and you should be good to go.


Hope all is well!

Hi Paul, I appreciate the input. So far I've only done some simple tests in RAW video mode, I'm still uncertain of using it with the small resolution that is supported by this camera. I mainly do h.264 video, and the 4gb file limit is present even when the card is formatted in exfat (unless there is a way to change this). The card has functioned great so far, works fast, no unexpected stops. Do you do RAW video?

Hello,

I bought a pack of neewer lapel / lavalier mics and I'm getting good results using it with my tascam dr-05, but I'm interested in making them wireless. I'm looking for a set of clip on trasnmitters that allow me to hook up 3.5mm mics and a receiver that allows me to use two or three of these at a time. Any solutions?

« on: February 19, 2015, 02:05:48 AM »
I've just learned that h.265 AND h.264 can support 10bit color. Pretty annoying camera dev's aren't utilising it.

This! I still don't understand why none of them (Canon, Sony, Panasonic... not so sure about Panasonic, Samsung, etc) don't have a DSLR or mirrorless with 4:2:2 10bit video? I've heard that its done intentionally to not kill off camcorders and other higher end products, in which case, this roughly translates to screwing with the consumer.

36
It's running now, hadn't realized someone replied. Thanks anyways.

CNET VIDEO...
OMG... Their HDR video is nothing more than ML HDR video with in camera combining, only at 720p60...

38
Maybe Sony sensor, so you do not need dual ISO.

Maybe, but more likely than not, it's just clever processing work with data from the sensor. It does have a DIGIC 6 on it I believe, which means it should be fast enough to bracket a frame at two ISO (maybe only 24p?) so that it can average them out? Hopefully it will allow you to choose two ISO's, and not have built in values that can't be changed. I'm really looking forward to this, I might upgrade to this from my T3i.

Do any other Canon DSLRs or camcorders have "HDR" movie to get an idea of what this will look like? Maybe other non cannon cameras?

39
So, the official specs for the 750D and 760D have leaked online... and I must say, they are somewhat interesting, especially since HDR movie is in the specs , mentioned as a seperate type of video mode than  just 1080p. Any idea what HDR movie is, does it compare to ML HDR minus the post processing and maybe reduced control?

Link to specs.
http://www.canonwatch.com/cw5-canon-eos-750d-eos-760d-images-leaked/

EDIT: HDR movie mode maybe = 10bit codec?
EDIT2: I somehow managed to post the wrong link, and can't find the original. There is another site that has the full official specs for these cameras, and not the rumored ones, but still the rumored ones are almost identical to the other sites official specs.

Good news! So I have developed the following workflow.

FOR H.264 VIDEO WITH NEGATIVE ML-ISO:
Import footage to 5DtoRGB
Export to ProRes 4:2:2 HQ
Color Correct in Premiere, bring highlights until pink highlights are very obvious.
Videolimiter on Chroma, Highlight Compression, reduce Chroma Max until 1% Below level where pink highlights are no longer visible.

Finished, footage is clean.

41
I don't need a wider FOV in the sense that I want the FOV of an 11mm, I just want the FOV of an 18mm when I engage 3X crop mode at 18mm. I know that wide angle lens adapters cause blurriness around the edges but with the 3x crop I think most of it would be gone correct?

42
I hear the Laing P-04s is also a great camera stabilizer, I'm ordering mine next week and will be receiving it a week or two from that day.

43
So I'm using a 600D, and I want a good wide angle lens adapter for my 18-55mm kit lens for using in 3X crop mode recording, but I'm not sure which one is best suited for this? I want to in essence, get the same FOV as if the 3X crop wasn't there to get non lineskipped video with a kit lens. Any recommendations?

As for external recorders, like the Atomos Ninja Star, is the video recorded on the 600D significantly better? (I understand that there is some cropping required). Would this device also be useful on the t4i and t5i and other newer gen models?

All I can think of for now, but if I have other questions, I'll just post here.

44
Looking around, I saw  that you can use  video limiter in premiere to correct this, and it works but seems like it slightly desaturates the rest of the image as well. Anyone know a better method?

I might get a couple dozen or more printed at a cheap price with one of the printing companies I occasionally do work with (not sure if a non reflective plastic would be the right material, or matte paper), maybe I'll end up selling them wholesale.

General Help Q&A / Re: 600D crop mode, correct usage?
« on: January 31, 2015, 11:12:18 PM »
Thanks for the reply, that makes everything clearer. I'm stunned at how much improvment the 3x crop gives me even in h.264 (halos around fine edges seemde to have disappeared completely in the quick test shots I did on leaves in my backyard), to the point that I feel like a fool for not experimenting with it earlier. I shoot in a lot of cramped spaces, so I think I'll buy a quality wide angle lens adapter, 0.45x that will allow me to use the 3x crop in these spaces, without needed to use a 8-11 lens (which I don't own  :-\), maybe some distortion, but nothing that can't be fixed in post I believe.

Cheers!

General Help Q&A / 600D crop mode, correct usage?
« on: January 31, 2015, 08:54:38 PM »
So I'm working with the 600D, and I found out recently that the 3x zoom reduces moire and aliasing (quite a bunch according to my tests), and it improves the overall picture quality by using a 1:1 ratio from the sensor. My questions are, is this the correct way of using the crop mode for h.264 and raw recording, from the canon menu? Or is it supposed to be used from some ML menu or module that I might not have seen? How to shoot in 3x crop mode with 720p a 30 or 24fps?

Thanks in advance.

48
So I'm fooling around with ISO 50 - 80, and getting awesome results with  a lot more DR than I can get without this. Only problem is, a few highlights are pinkish. I look around and I find people saying this is normal and fixable in post, but I haven't seen anyones process. Is it just selecting the regions and CCing them? Is there a more methodical way? Any feedback appreciated. Thanks.

49
Don't mean to bump this, but I spoke to another programmer who has more experience with a much broader range of programming than me (I've only done desktop apps, web and some pic processors), and he thinks he could do a PTP client for windows, open source, allowing others to port it. He would like to first review documentation on MLV (assuming that MLV is going to be the format in which this is going to be recorded in), and whatever other documentation he may need to see from the ML team. If he could do the windows client, would this get this moving?

50
I might be a bit misinformed regarding FRSP, and perhaps the lack of sleep for the last few weeks is getting to me, but how does FRSP improve video capabilities on the 550D and 600D? Wasn't it demonstrated a while back that you couldn't use the ARM of a DSLR to compress images fast enough to write them to an SD or CF card? Unless FRSP provides some way of capturing higher quality than h.264 frames at an acceptable frame rate (and I'm assuming that it would do this by using something other than the ARM), I don't see how this would improve video quality on the lower end models.
