Are these the "perfect" settings

[DrDeceit]

If I want to convert a video into an MP4(H264)
Are these the optimum settings for retaining quality

As in, if I convert a 1080p MKV, to a 1080p MP4(H264) using these settings, is the quality is going to be as high as it possibly can be?

Conversion Settings 

H264 
FourCC - avc1 
Level IDC - 0 (0 = Auto, 13 = Level 1.3 <10-51>) 
VBV Maxrate - 0 (KB/s) 
VBV Buffer Size - 0 (KB) 
Motion estimation algorithm - esa Exhaustive search 
Sets maximum interval between key frames - 250 (<0-300>) 
Number of previous frames used as predictors in B- and P-frames - 1 (<1-16>) 
Maximum number of consecutive B-frames between I- and P-frames - 0 (<0-16>) 
Use Cabac 
Use Multi-Threads 

Type - MP4 
Use system decoder (AviSynth) - Off 

Video Stream 
Video Encode - AVC(H264) 
Video Size - Default 
Bitrate (KB/s) - Default 
FPS - Default 
Aspect Ratio - Automatic 
Encode 2 Pass - Yes 

Audio Stream 
Audio Encode - AAC 
Sample Rate ( HZ ) - Default 
Bitrate (KB/s) - Default 
Audio Channel - Default 
Disable Audio - No 
Volume Control (+dB) - 0 dB 
Audio Stream Index - Default

Does your MKV already contain AVC video? If yes then why re encode the video?

[FulciLives]

There are programs that can take a MKV with h.264/x264 video and convert it to a MP4 and the only thing that should get converted or re-encoded in the process is the audio.

One such program is rebox.NET which you can grab here: http://www.clonead.co.uk/

DrDeceit - You may not understand that MP4 and MKV are just containers. Think of them like a box. A box could contain pencils or books or newspapers or any number of things that will fit in it. MP4 has more restrictions on what it will hold than MKV but your video should not need converting at all if it is H.264. MP4 containers are restrictive about audio though. AC3 and AAC are fine. DTS is not supported. Other audio formats may or may not be supported.

[DrDeceit]

I know they are containers, its just, I prefer to have an MP4, because, even though, theoretically speaking, the same thing could exist in an MKV or MP4 form... so the contents are the same... but MP4 is more universally compatible with things, JUST BECAUSE it says .mp4

Some devices instantly refuse to play an MKV, just because it is an MKV, not because it tries to play the MKV and fails, it just won't attempt to read it in the first place

So just rewrap it then. No quality loss, very fast. If you re-encode it you will get quality loss and it will be very slow

BUT - if the original video used settings or a profile that isn't supported by your device, then you have to re-encode it anyways

You may have just saved me a LOT of time.

I have at least 150GB of MKV files that are already H264, and I was going to re-encode and convert them ALL...

Have you tried simply renaming the file "BatmanBlahBlah.mkv" to xxxxxx.mp4 ? sometimes the simpler thing works the best. Give it a try, could save a whole load of time.
