Cinelerra does not set Format automatically

[carsten.otto@…]

Hello!

The video file in question is MPEG2-PES from a Sony HDR-FX1. That camera has a
resolution of 1920x1080 (1080i) and I was told the internal resolution was
1440x1080. That means only 1440x1080 pixels are recorded, but they are stretched
in output/storage so that you'll get 1920x1080. MPlayer plays and detects
1920x1080 and it looks right.
Cinelerra opens the MPEG (TOC) but only shows a 1440 pixels wide video, although
the format is set to 1920x1080. When I scale the image (x := x * 4/3) the
proportions look right, but I still only get 1440 pixels - the outermost pixels
are cut out.
I think cinelerra misinterprets some size information and therefore stretches
the video.

Please contact me for further information.

I would be grateful for any hint on how to edit some 1080i files and
pipe/transport the output to mencoder for further processing - with as much
speed as possible.

Thanks!

I was about to set this bug to INVALID, as it claims that the input video is
1920x1080, when it is indeed 1440x1080. The video does not have square pixels;
the aspect ratio is supposed to be 16:9, giving a display size of 1920x1080.

However, Cinelerra does not set the project size and aspect ratio according to
the file loaded. It uses the project settings from the previous Cinelerra
session. Is this wise? Will it not surprise, confuse and annoy many users?

cinelerra does not allow for per-asset aspect ratio setting, which is kind of
logical. your assets have to be of the same aspect as the project.

I noticed my original bug report is wrong. However, as I never saw a concrete
hint that 1080i-HDV actually is 1440 pixels wide and needs to be stretched, I'd
like to see a small message that tells me exactly that (with "don't show again",
of course).

Would it not improve usability if Cinelerra set the format to that of the first
file that is loaded? Or maybe suggest to the user that there is a format
mismatch?
