On2 VP7 encoder

[Alex248]

Hi! Is this possible convert video to on2 vp7 format? I have installed vp7 personal edition and extra codecs pack but I don't see vp-series encoders in drop-down. VirtualDub see this format. Can you please help me - thanks!

It's not format - it's just VfW codec.

How to set a codec to VfW?

But... it's not work in 'few' latest MediaCoder build. Bug?
Work in 0.6.0 3998 build and some older.

The vp6/7 do not listed in Formats. I had try to "play" with parameters as wrote in topic that you are reffers to but do not have a luck unfortunately.

The reason why I'm asking that I found that vp7 encoder on 64k bitrate have comparable quality with h.264 on 128k bitrate. Just trying cram all my clips into hpc with best size/quality balance

Of course - default, MediaCoder not use VfW codecs.

Set Encoder (Backend) = VFW Encoder
Then click on Encoder (Backend) button and type name codec library (if necessary, path).
VFW Codec file | File Path | vp7vfw.dll

And... it's not work now - waiting for new fixed build or use older.

Hi Placio,
I tried both the new and older build and couldn't get this to work. MediaCoder says its transcoding but then nothing happens.

I tried with build 3905.

Do you know which settings I should use. These are the ones I'm using right now:

Source -> MEncoder
Backend-> VFW Encoder

Thank you

I'm check.
Work for me (slow transcoding with this codec).
Of course VP7 codec is installed (in system).

Check console windows (F6).

Thanks for the help, I pressed F6 and this is the error I'm seeing:

BTW, I have Source set to "Auto Select", and Backend set to "VFW Encoder".

Thanks for any help

1. If You want transcode wideo used VP6 codec and mux it to FLV container... You need flip video image.

Go to Picture tab,
click on Rotation,
Flip the image upside down = Yes

2. Transcode video used settings as previous (and flip video), but to AVI container.

3. Revert all settings, open AVI (with VP6 wideo) and...

Audio tab > set Copy Audio
Video tab > set Copy Video
Container = Flash Video


BTW
Maximum audio sample rate = 44100 Hz.
