Bitrate very low, please help

[doobaadoo]

Hi,

i am on windows vista and i am trying to convert a vob to a ipod video. i have made my own profile that is mpeg 4 1500 kbps but when it converts it only does it at around 200kbps. i have tried all the different mpeg profiles on there and they are all the same. i can only convert them on AVC but i would prefere mpeg 4. please help!

Post a console log, please.

This is using my custom profile, if you need one of the normal mpeg 4 profiles just ask and il post it.

Thank you

[msopnet]

Does this only happen to this particular file?

Could you post what happens with a standard MPEG4 conversion?

[doobaadoo]

No it happens on all the mpeg 4 files but not quite as badly. This is the 1536 profile.

Sorry, Could I see an H.264 one quick? (I'm more used to those)

[Sketch]

It looks like your custom profile copied from an H.264 profile and only the codec has changed. This really doesn't work. Each codec has its own quality constants: the best MPEG-4 (q2) value is about mq10-15 in H.264.

From the MPEG-4 profile, you'll notice that it's q2 all the way. This means that the bitrates you are getting are the best you can for MPEG-4 at that screensize (320x180). If you're only watching the videos on the iPod they should look fine. Your only other option here is to turn off auto-resize and set it manually to 640x352, which will give you the bitrate you're expecting and improve viewing on a television.

Thanks i will try that.
