video quality severly aliased (ffmpeg)....
Closed, ArchivedPublic

Description

I have a video project that I have been editing for a few months. I started it using blender 2.49 under ubuntuStudio 9.04 amd64, saved out clips, video was clean.

loaded in some of the same source clips into blender2.46b. Output is aliased/ugly with same settings as in previous project. Opened old project and saved a copy of the first clip saved under 2.49 ... ugly video.

tried same tests with 2.5a ubuntuStudio 10.01 amd64 - ugly video

installed blender2.49 on ububtuStudio 10.01 amd64 Clean Video.....

Something broke.

Also Tiff file support has vanished in my blender under 10.01 amd64

Thanks for your time :)

There's not enough information here to be able to diagnose this report properly. Please attach a test file that can be used to reproduce this, as mentioned in the bug reporting guidelines. At least screenshots/movie test files would help, too.

As for TIFF support, whoever built that version probably was built with TIFF disabled, it should be working fine in svn trunk.

Im not sure if this bug is the same as one we had with ffmpeg, but there is a problem with ffmpeg in ubuntu 10.04 where it swaps the pixels in a way that looks like an odd aliasing problem.
Blender 2.49 includes its own ffmpeg which is why you'd not get the problem in that case.

Brecht worked around this by compiling our own ffmpeg.

Tiff support is now built into blender (not dynamically linked like it used to be). So probably your build was compiled without libtiff else you'd get an error starting blender.

Please attach an image of the bad ffmpeg output.

The official 2.6 build will have the latest ffmpeg included. For unofficial builds or own compiles we can only advise to compile the latest ffmpeg from and svn and statically link it. Not a bug, but a build issue, so closing.
