General Help Q&A / Re: 700D quality on wide angle lenses

C700d,

You are wasting valuable time, (not only yours !!!), asking too much on this forum, instead of testing your camera by yourself.

That's all I've been doing for the last 3 months, although the speed hack slipped me by.

Quote from: IDA_ML on December 28, 2018, 04:29:31 PMYou received tons of valuable information already and if you read it once again very carefully, you will understand how your camera works, what its limitations are and what is doable with it and what not.
I would also argue I know what is possible with my camera, hence my posts here, asking for your valuable information in how to achieve it.

Quote from: IDA_ML on December 28, 2018, 04:29:31 PMAnd finally, a friendly and good minded advice.  Stop shooting and pixel peeping wires and these ugly transformer posts on the streets.  There are much more exciting objects to film out there, especially over this time of the year.
They were near me at the time and seemed a good example to test for aliasing, which was the main issue apart from the low resolution, I know they are ugly as sin. I will go out with these new settings and film something prettier, that's not too difficult.

Quote from: IDA_ML on December 28, 2018, 04:29:31 PMJust go out, find them and film them.  If you expose to the right, focus precisely and compose your shots nicely, your 700D will not only shine but will also exceed your expectations, believe me.

I know, but it's easy to say that when you understand and finally have a build and settings that work for you. I am nearing that stage but I won't get there unless I ask questions, usually infuriatingly questions, that are simple to others. As you say time is valuable and sometimes a simple question takes the longest to find the answer. Look, I apologise if I've wasted anyones time but I am short on time and need to get the best results from the camera ASAP. The information given so far has been great I agree, but in my experience with ML, I get so far then another problem arises that stops me, and usually there isn't a quick answer on the forums or through the search (which I always do first, an example being how to install the SD card hack, I had to use a build with it pre-installed), yet sometimes it's quicker to just ask someone in the know and in the now. Yes, annoying, but it helps me quicker and I appriciate it! I will try not to ask anymore "silly" questions as I'm quite happy with the results, my last few posts are simply me running into problems recording in crop mode, with the liveview being difficult to see what is being accurately recorded. - If you can find me anywhere in the forum that explains this accurately, then please link as I am unable to find myself through the search and that would save you time typing. Apart from that, I feel I'm very close. I don't need to know about exposure, framing, focusing etc, I am well aware of how to film. The liveview issue is the only big issue for me right now (touch wood!)

Quote from: IDA_ML on December 28, 2018, 04:29:31 PMGood luck and don't forget to post some stunning videos on the forum!

Thank you! That is my goal! My next goal is to create a video that doesn't make Walter throw up in his mouth!

P.s Thank you for the clarification on the 1800x1008 resolution being changed dfort. To me that is confusing because if our goal is to shoot in crop mode at 2.5k for example (which my current build has a preset for), and then turning  "Movie crop mode" on which then reduces the resolution (albiet still high) then what is happening there, it still leaves confusion on how people are shooting in those resolutions without a half accurate liveview. That is another question that I doubt I will be able to find on the forum, and risk others becoming aggrivated. "Movie crop mode and the crop_rec module are two different animals." - This is an example of something I can research on in the forums imo and will do so. So you don't have to answer any questions. Thanks again for your time!

Hi dfort, again thank you. I've just tried this and it brings my resolution down to 1800x1008 ...normal?

Also, does the option "crop mode" need to be on at all? I know that sounds stupid, but it's been off this whole time and if I select it it only has the one option of 720p 3x3 which is something, I don't fully understand yet.

Thanks dfort I will look into this.

At the moment my set up is as follows:

Non crop mode - Recording in 1736 x 976 x 30 fps x 14 bit lossless- There is still aliasing, which is normal but the quality is better for sure.
Crop mode - Recording in 1920-1080 x 30 fps x 14 bit loseless - The aliasing is much better but I worry about being able to compose shots well enough as well as recording on the move.

I can record in crop mode in higher quality but not for very long (8-12 seconds) for example 2520x1080 30fps x 10 bit lossless but another problem is I'm trying to match drone shot aspect ratio with the 700D, so that resolution makes everything go out of whack. Getting there slowly though, thanks everyone. I'll update with MLVapp examples soon. Again, really appriciated.

I'm sure I'll be back.

Thanks everyone, I really appriciate the detailed replies! I was getting somewhere with another build last night which had an auto UHS-SD hack and I was able to record in higher quality and at higher speeds.
This is the build I used - magiclantern-Nightly.2018Jun17.700D115_sd_uhs by Dannes or something similar.

I've taken on your advice and went with a clean install but that 4k build does not have a UHS-SD hack module and for the life of me I cannot find where or how to install it without it preinstalled in the above build. I did copy the modules and LUA script file from the build above but then I was getting "Unable to detect RAW" errors.

With this 4k build I am unable to even choose 1736 x 976 resolution. The max it will let me choose 1728x972 at 16:9 (I need this aspect ratio for framing compostion) at 30fps and the write speed is 84mbps and skips frames immediately.

On the build with the UHS-SD hack I am able to select 1736 x 976 x 30 fps x 14 bit lossless and I have done three tests, all exported through Premiere at their respective FPS apart fromthe picture example which is a screengrab from MLVapp.


First test.
1736 x 976 x 30 fps x 14 bit lossless and 60 shutter speed. https://vimeo.com/308489397

The second clip is an attempt at shooting in crop mode? No idea if it's working correctly, I pressed zoom in 5x, live view is black and white, hit record.

In my opinion the aliasing is still pretty bad at in the first clip but in the second; in crop mode, it appears to be better on the powerlines, however there is noticable juddering on the cars now....


Lastly I tried shooting in crop mode at
2520x1080 x 24 fps x 12 bit lossless and 48 shutter speed - https://i.ibb.co/jwBLNyw/vlcsnap-2018-12-28-10h36m18s722.png - little under exp I know.


How am I doing? I don't know, it still feels pretty poor on the wide angle lens, I understand that technically there is no issue with the lens but it still looks bad doesn't it?

P.s I must say that I am notlooking for unlimited recording time anything from 10-15 seconds would be fine and that I always shoot in either 24/48 or 30/60. I am using the sandisk extreme pro 4k 90mbps card.


More issues:
1. If crop mode is working correctly, then how do you compose your frame when recording, especially if you are moving with a gimbal? I understand there are trade offs with ML, though is a slow black and white liveview one of them in crop mode recording? - Am I using crop mode correctly?

2. What is this in the top right hand corner, I understand it's recording time usually but what is the number on the right? Am I losing frames? https://i.ibb.co/KV4SLFB/frae.jpg

EDIT: Now I can't record in crop mode at 2520x1080 x 24 fps x 12 bit lossless and 48 shutter speed without instant frame skipping..... come on need a break.

Thanks for the tips and links dfort.

The link with the dual ISO and the guy with the build with no aliasing was one of the first I tried and spent a long time trying to get working. The Dual ISO mode would first give me an error (which I sorted) but then would give flickering video which I could not figure out how to fix. The cropping and binning I do not really understand, and there is the problem of the liveview grid being cropped or difficult to use for framing, which is essential.

Although the aliasing was like sour milk to Walter, I do think the video quality is passable (obviously not to consumers or professionals, but to realise my vision and ideas) on smaller screens and is the best I will be able to get.

Completely fair comments, I know I'm limited in terms of producing quality that is consumer worthy, and quite frankly it's not good enough.

My current goal is just to create something that can showcase quality in terms of mainly editing, cinematography (at least barebones framing, I don't have an ARRI ALEXA in my rucksack to solve the aliasing) and story-telling for possible employers, like a showreel just to show what I can do (The above being just a test in getting the best recording quality I can).  Though deep down I know without a better video camera I'm ******, especially if people are turned off after the first 12 seconds.... But without time or money this is what I'm stuck with unfortunately.

The ML videos on the 5D3 do look gorgeous and I've thought about that being my next purchase. Until then, should I just give up?

Thanks for the tips everyone.

I will look at the post from the person who has great quality but all that binning and cropping and a squashed live view seems way out of my depth, espcially the live view issues, I need to see it to be able to see what I'm recording!

Here is a small test video I made (I'm aware there's a lot of issues, motion blur, juddering, frame issues etc), but I'm not too disappointed with the quality!

What do you think?

Thanks Walter, literally just came across these steps!

May I ask how I get back out of crop mode? It's messing up my aspect ratio grid on the live view now.

Edit: Nevermind, got it. I will make a short edit from the clips I got today and come back!

If you mean the magnifying glass (not heard of loupe before) then it zooms in but has no effect on cropping the recording, just makes the view finder go black and white.

I am using MLV app's anti- work arounds but I am unaware of any extra help for that problem in say, Premiere Pro apart from noise reduction maybe.

I will have a look around the forums for anti-aliasing help. Thanks, any more info fire away!

Thanks Walter,

In the first clip I was testing 60 fps so it was in 720p. My mistake.

Here is an image from 1080p 30. - https://ibb.co/vXHr0bx - Better, but still smudgy.

Could you advise me as to where the option is to switch to crop mode? All I have is movie crop mode but it says it's for the 600D.

Also, more information. I am recording at a rate of around 38mbps which is the max I can do for 20 seconds before frame skipping.

Apologies, I will try to answer those questions.

Recording mode as far as I understand is - RAW - no cropped mode, can't even find any options in the menu apart from "Movie crop mode" which is off. No crop builds being used. Current build is nightly.

Workflow is currently - MLVapp to dng then After Effects. 50mm footage is clear in good light and very useable. 

Thank you for your fast reply!

General Help Q&A / 700D quality on wide angle lenses
December 24, 2018, 03:29:13 AM
Hi all,

Still desperately trying to create useable footage this camera and ML. With a 50mm lens I'm producing some nice footage. However with my Wide angle lens (Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens) the quality is worse than a potatoe.

https://ibb.co/4ZL6JHV - I don't even know how to explain the quality issue, it's not sharp, it looks off and smudged and weird. It is like this on many different builds.

Will a sharper wide angle lens correct this issue?
I've also realised that to stop frame skipping from happening I lower the resolution; fair enough, but how can I record at a lower resolution without it cropping the area of recording on the live view screen? It's almost impossible to see what's being recorded in frame while on a gimbal etc.

Thank you for your advice

Raw Video / Lag in Live view

Any causes for this?

I've disabled FPS override.

Thank you

P.s Apologies, I've fixed the previous post.

Hello all,

I'm in desperate need and becoming so frustrated in my attempts to get this so called better quality.

I have been trying many different builds including nightly, experimental, 10 bit versions, yet my footage constantly borders on flip phone video quality.
Can anyone please advise me on what I'm doing wrong and what the best possible build and settings I need to input in order to get better quality footage without awful pixelation?

I am aware I am limited by the camera itself and I am not expecting 4k professional looking footage but something that is at least better than the 700D default compression, which is meant to be the whole point of ML.

Currently I am shooting on the experimental 10 bit build, shooting raw at 10bit at 1x, 16:9, and at a resolution whereby it teeters on SD card write limit of around 35/40mbps soI can shoot without it stopping.
My work flow is exporting to DNGs images through MLVapp and then exporting through Premiere Pro upscaled to 1080p (also tried 720p) with everything set to max in terms of export quality.

I have a number of lenses (mostly kit but nothing too awful) yet the quality is always the same. It is a pixelated mess! Where am I going wrong?

I have attached two images, the first is how my exported quality looks and the second of the plane is a compressed video of someone else shooting a plane on a 700D equipped with ML. Why is mine so awful in comparison?

He is also using kit lenses so I'm not sure what is happening, though I am starting to think it may be the sharpness of my lenses (lack of) causing the issues, but there is still a huge amount of sludgy pixelation.


Thank you for your time and answers! And apologies for the rage.
