Blocky MKVs

[romanticwarrior]

I have a couple of mkv hd movie files which i wish to convert to avchd.

Using multiavchd or indeed avchdcoder produces broken blocky playback (visible on the preview screen in multiavchd).

When i play these mkvs in vlc player they are smooth and perfect but in windows media player blocky as above.

So clearly the files are not the issue. Codec issue? Ffdshow issue?

What must i tweak in either of these great softwares to ensure they they are handled as well as in vlc please?

Am currently trying bdtoavchd to see if this nails it!

Might be a directshow decoder issue. VLC doesn't use directshow, but all the other 3 with broken decodes will be using directshow

Use graphstudio to render a sample video, find out what directshow decoder you are using

On win7 you can use win7dsfiltertweaker to change the decoder (especially if it's the default microsoft decoder)

New ffdshow builds should be error free, you can update that ( but you need that filter tweaker tool , unless you are on older OS)

Thanks for that,interesting.Sorry forgot to load my system info before.

So how can i change the decoder on this OS then?

ffdshow should have highest merit when it's installed, just make sure you have a recent version, and enable ffmpeg-mt for avc decoding

If you see the ffdshow icon pop up when you use WMP to play the mkv files (I'm assuming they are avc, check with mediainfo) , then ffdshow is the decoder

Installing the latest ffdshow did it?

Clearly you are a genius!

Thank you!
