Letterbox problem

[Rutherberg]

Hi,

I try to add the letterbox effect to my project, but it doesn't appears on the video, even after exportation. It is probably a user fault.

Here is the project specs :

- original video : 640x480
- type of exportation : avi (h.264), 768x576 4:3 PAL, high quality
- Running on ubuntu studio 12.04 (xfce)

The other effects are working well, the problem is just with the Letterbox.
Could you please tell me what could be the problem ?

Thanks in advance !

Hi Cenwen,

Here it is :

Code: Select all

Thanks for your help !

PS : if you prefer to continue in french, there is no problem, it is easier for me. But it is maybe less interresting for the whole community...

Like you want.

What is the extension of this file ? I'm thinking that the reason of this output a bit queer. Do it again with this one.
And for having more explanations, could you tell me what distribution, version of Openshot, MLT and FFmpeg do you use ?
Thanks.

Hi Rutherberg,

When cenwen said

ffmpeg -i original video

He meant to use the name of the original video. If your movie has the name Avatar.mkv, he wants you to do

Code: Select all

ffmpeg -i Avatar.mkv

The project is composed of multiple vids, but they are all of the same source. (Zoom Q3, 640x480, PCM 44,1Khz 24bits)
I just saw that the video is cadenced at 30 fps, and the project is at 25 fps. Is this a problem ?

The distribution is Ubuntu Studio 12.04 (xfce), Openshot is at 1.4.0
When I look in my Synaptic, I see that MLT 0.7.6 is installed.
And there is my ffmpeg -version :

@cenwen : I think it is wiser to continue in english, let the community benefit about that

Ah Avatar my preferred film with Lords of Rings.

@Rutherberg

Argh. You are using the fork of FFmpeg which is full of bugs.
However, we are not at this step. You should update your version of Openshot, the last one is the 1.4.2.
See here how to do that : https://answers.launchpad.net/openshot/+faq/1850

You should update too your version of frei0r-plugins. See here to grab the last deb following your architecture : https://launchpad.net/~sunab/+archive/kdenlive-release/+packages

And try again. And say us if you have the same issue.

[Rutherberg]

So, I upgraded Openshot at 1.4.2 and the frei0r-plugins and... Yes ! It works !

Thanks for your help guys, that was very useful !

[Cenwen]
