Post timelapse and video aspect in Canon?
Hi guys, i'm kinda new here so... I'm very interested in the topics that you guys post! keep it up.

Now ... here is my question. I started a new project mixing timelapse photography and video, in the same scene. this is not difficult with a FF dslr and a tripod filming in the same spot that the timelapse is being shot.

Now my question is the following. I shoot in 16:9, which I think is the aspect of a crop 1080p, am I right? if that so... why is that the image vs a video frame does not look the same aspect? I mean, It look like they have some kind of lens correction, but this is comparing both aspects, without any intervention or post production.

This is very strange to me, and I don't know if i'm missing something. Have you ever noticed that?

thank you guys! any help would be a great step forward to me.

because they are different aspect ratios - HD video is 16x9 and Stills are 3x2 - that why you need to resize and crop time lapse stills to fit into HD video.

actually I did that, and it looks like if I were some kind of a lens aberration correction in the video, and not in the stills. if you resize to match the video/image, it doesn't look the same. I took the video and put an image on it (after effects), and after zooming to 100% and put transparency 50% in the image, it looks like a different aspect. i'm a little confused about this.

maybe you could post an image of what you are seeing - can you also check that you are scaling the Still image the same on each axis - ie. 50%,50% rather than 50%,40% (or something like that) - just guessing from limited information.

guess what, I find out what was going on. It is actually pretty simple (and I didn't knew it). I usually unscrew the lens just a little bit to avoid any mechanical flickering when shooting a timelapse, and from what I compared, this causes some kind of a difference in the final picture in aspect. I'm guessing its because the optic gets a milimiter far away off the camera or something. I've tried this twice and results are the same. If i'm gonna shoot timelapse plus photo, I'd better not do that.

thank you pixelbot !
