Higher quality encoding

Dec 7, 2012 at 8:34 PM

First off, thanks for all your hard work.  I love MCEBuddy and recommend it all the time.

I am wondering how to get a higher quality mp4 encoding.  For instance I have a 30 minute HD recording of a sitcom that is around 3 GB.  When its processed from MCEBuddy it comes out around 280mb.  The quality is obviously blocky when played on a HDTV (great for iPad and other uses though).  I'm using the MP4 High Quality preset and when I look at the profile in the confg file I really don't understand all the parameters.  The bitrate looks high enough at 1800 but everything else looks like a foreign language.

Any help would be greatly appreciated.

Here is the profile, I haven't changed a thing but thought I'd include it incase something is wrong:  

[MP4 High Quality]

Try increasing the Resolution and Quality slider in the conversion task page.

Oh, so you're saying its easy.

Thanks for the quick reply

Hi - new user and after trying the high-quality profile I have exactly the same question as I wasn't satisfied with the output. I'll try your suggestions there too - but for my understanding, how does the quality slider relate to the options above - does it append different things to the command-line depending on the encoder (if so what is it actually appending) or is it just changing the bitrate setting there?

I guess when I've been looking into mencoder settings I see things like:

 --crf 18 --preset slow --tune film

and I'm struggling to correlate these back to the quality related GUI options I have in MCEBuddy. If I wanted to create a custom profile to replace all the individual options with a --present and --tune setting would that work ok (any help with the syntax appreciated) or would that not play nicely then with the GUI options like the quality slider etc (I'm assuming --crf would clash with it)?

The application overall looks fantastic btw - can't wait to get it all up and running....

Quality slide in conjunction with the Resolution slide change the bitrate (-b) or the quality scale (-q) settings depending upon how the profile is written.

It does not add /remove parameters.
