Hi!

I am going to make a movie for advertisement that has the resolution of 204x614.
In the profiles settings I made a new profile, and set the:

Size: 204x614
Framerate: 30/1
Pixel aspect ratio: 3/9
Display aspect ratio: 3/9

Then when I add a png clip that has the same resolution (204x614) and drop it in the time line, It appears as a small square reaching to both edges left and right, but with big black bars on top and bottom... what am I doing wrong? Should it not fill the project screen? If I drop a "Crop, Scale and Position" effect on it and scale it on the y axis it looks normal, but this seems not the right way to do it...

With Display ratio = 1/3 and resolution ratio = 1/3, pixel aspect ratio should then be 1/1. Not sure it is the cause of your problem?

I just figured that out too. I looked at Pitivi and it calculated the display aspect ratio to 102/307. So I copied that, and set pixel aspect ratio to 0/0 and it worked
What is the use of display aspect ratio when one is already setting the resolution? And what is the purpose of pixel aspect ratio?

Entering 0 in fractions is risky, you may face bugs if software don't handle this exception properly

But is your image stretch problem fixed?

Resolution ratio can be different from Display ratio, eg for widescreen DVD where stream is still 4/3 (768/576) but image is stretched to 16/9 => Pixel ratio is 4/3, they are not square any more...
That's true that 2 settings should be sufficient, DAR and PAR should be redundant (but maybe I'm wrong?)

Oh, OK! I set it to 1/1 then, but I am not really sure what the setting is for... the images and the clips now fills the project monitor very nicely. So thanks a lot for helping with that Thanks for explaining the difference of resolution and ratio!
