Depending on how your camera records, it reads (row,column) 1x1, 3x3 or 5x3. 1x1 and 3x3 don't need stretching, 5x3 needs 1.67x stretching. Maybe you could share a short MLV and we can have a look.

Hello, we are talking about this in another post, I don't want to start a new one so I give you the link:

Thanks!  :)

And you did not touch the source code either, which was what I was talking about ;)

Apparently you were the first person trying to use raw video on 1100D :)

Why? If anyone else would have tried this before, they would have noticed this issue, as it's too obvious. Since they didn't... QED.

FYI, I don't have this camera, so I wasn't aware of the issue.

Hello, thanks!

I just paste one of the links I found on YouTube:



Maybe they just crop the footage, I tried to avoid the problem in this way:
I want to get 2:66:1 ratio, 1280x481.
But I record in "16:9" with a 960x324. Then I make a new composition in after effects using the 1280x481 resolution and I just change the scale till the height fits the composition, obviously I cut the edges a bit, but since I'm using 2:66:1 instead of 2:35:1 it's not a big deal. Not sure if it's wrong but it works, and the ratio is correct.

If I understand well, the 1100D operates in "720p" mode by default, but using a 3x3 pixel binning (with line skipping). All other models use 5x3 binning in this mode, so their videos need to be stretched, but this doesn't apply to 1100D. The generic code assumes 5x3 binning in 720p for all models, so it has to be added as an exception. It needs to be corrected here:

https://bitbucket.org/hudson/magic-lantern/src/d318f774b24ecc7d533ab79dd9418d097442fd81/src/raw.c#lines-905

PR welcome, but I may not be able to look into it until holidays.

Yes the 1100D operates in 720p, but I didn't touch anything regarding binning or other settings, plus in many 1100D videos they didn't talk about pixel binning, they just wrote in description the same settings I wrote in the previous post. Thanks again!

No workflow info for post. Try again.

I used MLV app, default settings, no stretch applied, exported in Prores4444. Then I tried the MLV Converter, default settings, exported in DNG. I use after effects but it doesn't matter because the problem is not in the comp settings, it's probably in some step before the post process in after effects. With these two Apps I get the same results: a perfect 1280x326 footage where there's no need to stretch the height. I don't undestand why. Thanks.

Without details about settings, workflow any answer is right, wrong, irrelevant.

Hello, I'm using the 2:35:1 ratio, resolution: 1280x326, 14 bit. 25 fps, shutter speed 1/50, RAW.
I'm using the EFS 18-55mm III. When I select the 1280x326 resolution it also says "stretch by 1.67x to get the full 1280x544 resolution in post". When I convert the mlv files the video doesn't look squeezed as it should be. It's just a perfect look video in 1280x326, it's like a crop in 1280x326 more than a squeezed version of the 1280x544. That's why the video looks wrong when I stretch the height by 1.67x. I saw many tutorials online and their videos looked squeezed (vertically only) so they can apply the stretch by 1.67x in post, anyway my footage is just already perfect regarding the ratio but the resolution is totally wrong. I hope it makes sense, thank you for your time!

I'm using the app, but I am not able to get the right ratio. I should get 1280x544 stretching by 1.67x but the heigh is wrong, I'm using a canon1100d 2:35:1, 1280x326.

I'm searching since two weeks to get some info about that, I searched in the forum but I didn't find anything similar to my problem. I tried again other settings but it doesn't work. Could someone help me? Thanks  :)

Hello, I am a musician from Italy, my hobby is filmmaking, I own a Canon 1100d and I installed magic lantern one year ago after I discovered its brilliant features on Youtube. I am really happy with it since magic lantern breaks Canon cameras limits! Thanks for your amazing work!

Raw Video / Stretching RAW Video Canon 1100D Problem
November 17, 2019, 06:24:21 PM
Hello,

I installed the last firmaware available for my canon 1100d, I recorded a couple of RAW videos in 14bit, 2:35:1 ratio and 1280x326 resolution. I searched online for an answer but I didn't get the "stretch 1.67x to get the 1280x544 resolution in post" point, I tried to stretch vertically the video and I exported it as 1280x544 but the video looks stretched, so probably I'm doing something wrong, could someone please help me?

Thank you for your time,

Michele

hello, my problem is about 1100D Canon RAW feature, I installed the last experimental ML 10/12-bit RAW video version (2019 Mar 24). I expected something like that: https://www.youtube.com/watch?v=F_zLhgMvpOo

But everytime I record any video, it looks so bad like a super zoom. It doesn't matter if I choose different ratio or resolution the crop/zoom effect is still there. So did I install the wrong version or..?

Thank you for your time anyway.
