wrong framerate interpretation

[bartcuijpers]

While working around another issue (viewtopic.php?f=4&t=780), I noticed that QT files with the DNXHD codec (exported from AE) with a framerate of 50p are interpreted as 25p resulting in a encoded file playing in half speed.

A source file to test with:

Thanks!

An example to follow: Submit samples right away Great! I will take a look.

Hi bartcuijpers,

I think you need to submit your workflow. In my tests FFAStrans seem to find the correct fps of 50.

After some re-testing the problem seems to be different than I thought at first...
The output file isn't playing in half speed, but the duration metadata is incorrect; showing double the duration.
When playing the file in VLC it stops at 6 seconds.

I made a package including the workflow, input- and output files;

Thanks for responding!!

I have found the problem and it is indeed a bug. Thanks for reporting. Expect a fix in the next version. In the mean time, I suggest you skip the "A/V Media" decoder. It's not needed in your workflow and it's the one that introduce the issue.

Thanks Steinar!

For my information... when is the AV decoder mandatory?

If you want to apply filters. The "A/V Media" actually creates an AviSynth script and all the filters are avisynth based.
