Video und Audio Codec?

  • #10, by GreenLightDevelopmentMonday, 31. March 2014, 13:57 10 years ago
    Gibt es hier aktuelle Erfahrungswerte, welche freien Codecs, in welchen Containern am "besten laufen"? Nativ wird das angestrebte Projekt in 1080p erstellt und in diesem Bildformat sollen schlussendlich auch die Videos sein (1920x1080@25, 44.1@320,2).

    Ok, ich hab' mich heute schlau gemacht, wegen dem codieren der Videos. Wenn die Codecs VP8 und Vorbis empfohlen werden, frage ich mich, weshalb beim öffnen der Videocontainer "nur" AVI und WMV vorgegeben sind. Klar, man kann auch andere öffnen, aber dies scheint 'generell' nicht vorgegeben zu sein, beim auswählen von Videodaten. Es ist natürlich auch möglich, einfach einen anderen Container zu nutzen, aber dies wäre einfach nicht Regelkonform ;-) *korinthenkack*
    Der korrekte Container für VP8+Vorbis dann WEBM und nicht AVI oder WMV.

    Allgemeine Informationen, für die Verwendung von VP8+Vorbis:

    Hmm in vs4 it should say that the recommended video format is .mkv & for audio it should say .ogg & .opus. You can technically use whatever format you like by selecting the all files option, but we recommend using mkv with vp8 & vorbis for video & .ogg for audio because they are supported & because they are free to use. Most other formats require you to purchase licenses for them (not from us, but the license/copyright owners).

    Yeah, same here. But the thing is, the proper Container for VP8+Vorbis is WEBM, not AVI or WMV. My question is, "why isnt it possible, to select WEBM nativly from the client, if its recommended, for Indi/Free Projects?".

    And i neverr worked with Opus. Using OGA, OGV (OGG) for general Websitestuff...

    No, that is not correct, the proper container is Matroska (MKV), because its the most flexible container. WebM is establishing itself for web usage. Don't worry if we haven't listed it in the dropdown, that has nothing to say (in fact they're just the most common formats when we built the ffmpeg implementation), in the bottom line it's just ffmpeg. Also we have a ogg and a opus implementation for sound, so use one of these formats for sound, otherwise the engine will fallback to ffmpeg and that might not be that stable.

    So if VP8+OGG is recommended here, inside a MKV Container, why isnt in selectable by default, inside the client? Just wondern, not trying to trolling ;-)
    I dont mind, to use other Containers and Codec, i just want to be sure, to stick with real defaults, that given by Visionaire.

    atm im using a 2pass coding, based on this, with FFMPEG:
    %FF% -i "%~1" -strict experimental -vcodec libvpx -b:v 2800k -bt 234k -r 25  -aspect 16:9 -trellis 0 -me_range 16 -i_qfactor 0.71 -b_strategy 1 -qmin 3 -qmax 51 -qdiff 4 -sc_threshold 40 -sn -pass 1 -passlogfile ./pass -threads 2 -y %TARGET%.webm
    %FF% -i "%~1" -strict experimental -vcodec libvpx -b:v 2800k -bt 234k -r 25  -aspect 16:9 -trellis 0 -me_range 16 -i_qfactor 0.71 -b_strategy 1 -qmin 3 -qmax 51 -qdiff 4 -sc_threshold 40 -sn -pass 2 -passlogfile ./pass -c:a libvorbis -b:a 128k -threads 2 -y %TARGET%.webm

    Just plain, because we haven't updated that. I look into that tomorrow, so that the final 4.0 will have that wink
