Subject: [transcode-users] DVB Recordings transcoding retaining
correct screen appearance but without stating aspect ratio or wxh
Reply-To: transcode Users Mailing List <transcode-users@exit1.org>
Forum:
When I record DVB recordings in Kaffeine, the aspect ratio is 16:9,
with the wxh shown as similar to 4:3, but the presentation in
whatever player I choose is correct. This remains true after
editing with dvbcut to libavformat mpeg as well.
When I transcode them to xvid , using no options to specify
appearance, or using --export-asr 3 on its own does not work, but
gives a 4:3 ratio on playback with automatic ratio selection.
Stipulating aspect ratio 3, and wxh 720x400 gets me a good result,
but I lose about 7fps speed in doing this, from having a rate of
about 30fps, to about 23fps.
Is there a command line option I can use to retain the correct
appearance WITHOUT losing transcoding speed?
