test sequences

ranchu · 9th December 2012, 23:03

Hello,

In some of the codec I use I see a list of test sequences such as parkrun, mobile etc, but with resolutions and fps which I can't find in the net. I would like to ask how I should find these sequences or if there is maybe a way that I can generate these sequences by myself.

Thank you very much,
Ranchu

Most of the "popular" test sequences can be found here:
http://media.xiph.org/video/derf/

Those are either 352x288 (CIF) or 1920x1080 (1080p). Some even 3840x2160 (2160p).

If you need a resolution that differs from the original sequence, you'll have to crop and/or apply a resize filter.

The frame rate you can choose freely anyway

Thank you for the answers,
magc_yunjiao, It seems that the site you mentioned does not work well. I could not see any content in ftp://ftp.hhi.de/HHIMPEG3DV/
Lord Mudler, can you refer me to a tool which I can use to resize a known reference ?
Thank you,
Ranchu

If you need a CLI tool (e.g. for batch processing) FFmpeg should do the job. In case you want to encode with x264, you can use x264's built-in resize filter.

Then of course you can always use Avisynth, which has various resize filters available. Or maybe VapourSynth nowadays.

And if you need a video editor with graphical user interface, you may use VirtualDub or Avidemux. Just be sure you save the resized video to a lossless format again...
