Hi,

I installed kdenlive in both ubuntu and windows 10, in the windows version which I'd imagine is the same as linux, I have a weird issue, I wanted to use the rotate feature since my phone which was rotated during filming, has left the video such that when you watch it, the video clip is off by 90 degrees at some point in the video. I have cut the first part of the video which is horizontal as it should be to show a fish in an aquarium, however, in the second clip when i use the rotate feature, rather than seeing the video as a full screen, it shrinks it down to like half the size of the screen - as you can see the black bars around it. I eventually found a zoom feature however it only zooms the video within the confirms of the black bars. Does anyone have any ideas?

I found the solution, maybe,

"Thu Nov 02, 2017 11:31 pm I had the same issue with zoomed square images inside a 16:9 aspect ratio project.
After a lot of tinkering I realized this bug(?) only happens when the Timeline composition quality is set to "None" or "Preview", in "High Quality" mode the monitor works as expected and the rendered video is just fine."


I am not sure how to implement the feature, what steps do I take to try to follow the above course of action? To the left side of the screen i found a feature which is presumably for the above to change the quality, however, i still have the video just showing in the small section of the screen.

Thanks in advance!

Hi,

Any takers on this? Also is there any way I can see on here how many people viewed this post? Thanks in advance.

Like now you have 36 Views

for this kind of jobs (rotation from smartphones) i usually use directly FFMPEG to rotate the image with a loseless compression (i'm using Windows BTW, and Kdenlive is installed on "Program files" folder)

these are my BATCHs (.bat) for doing that:

to rotate 90:

c:/programmi/kdenlive/bin/ffmpeg -i C:\Users\user\Videos/in.mp4 -vf "transpose=2" C:\Users\user\Videos/out.mp4

to rotate -90:

c:/programmi/kdenlive/bin/ffmpeg -i C:\Users\user\Videos/in.mp4 -vf "transpose=1" C:\Users\user\Videos/out.mp4

usually i place the 2 batch(s) in my video folder.. after that i place the clip to be rotated as in.mp4 in the same folder... and after the rotation i have the out.mp4

H thanks for the response, which is helpful.

Where can I see how any views my post has?

Also the rotate suggestion sounds like a lot of prating about cutting the clip out, saving to new file, then re-adding it again, is there any program that can do this more easily?

using ROTATE AND SHEAR effect, the rotation and zoom can be made with only 1 effect.

Hi,

What is do you mean by "1 effect"?

Also it was that function I was using.

Kind regards

creating a vertical project ( NEW PROJECT --> CUSTOM --> VERTICAL HD 30 FPS )
you can import an horizontal clip an make a vertical layout just using ROTATE AND SHEAR... rotating by 90 .. and zooming to fit the vertical layout.

Thanks for the response, I'll try that next time I need to rotate.

Farid pointed me to the "disable autorotate" option on clip properties... this can solve a lot of rotation issues.
