Hi,

I'm trying to render a video made of JPEG images. No animations, just passing pages from a scanned magazine containing pictures and text in small fonts with some related speech track. Thus, those images should be watched in its original resolution (around 1800 x 2500 px).

The thing is I'm unable getting Kdenlive to render a video containing those images in a clearly readable resolution even specifying to keep the original one: the fonts are always somewhat blurred. If I use avconv I have no trouble with this, but I would like to use Kdenlive.

I guess this is related to how Kdenlive transcode the images before rendering but I'm unable to find a way to change this behavior (Kdenlive won't let me specify a transcoding profile for such a bunch of images).

Please can someone point me in the right direction to solve this?

Thanks in advance,
Antonio

1st, did you set your project resolution to the same as images? If not, everything will be scaled to probably 1080 pixel height...
then, did you try to increase bitrate at rendering? (Or with 0.9.10, set a better quality factor in VBR)

did you set your project resolution to the same as images?

I'm not quite sure but can't this be modified afterwards?

did you try to increase bitrate at rendering?

Yes, but it didn't work (I should try your first point nevertheless).

Cheers,
Antonio

Using 9.10 on Ubuntu

On some of the images I render with KdenLive via Huffy lossless profile,
I get a pattern 35-50 pixels wide occuring at the bottom of the frame.

What is odd is some image sequences don't have this pattern and some do.

Can anyone help me define or resolve this problem.
