Blu Ray Encoding

[donfrenchiano]

I just got a BD-ROM for my PC and began using megui to encode them to mkv or avis. This works fine but i use Linux as my main OS. I could not get megui (more specifically .net 2.0) to work under wine so eventually i found a mixture of tools i could rip and encode blu rays all within linux. (Wine + DVDFab Decrypter HD and sometimes wine+eac3to to get ac3 audio files, and avidemux). avidemux has been working fine but i dont seem to have as much control over the encode. Maybe im just not looking in the right place. For instance megui would scan my source and see if it is progressive, interlaced or mixed. Ive had a few blu rays that i thought were progressive but megui found them as mixed. Not sure if megui was wrong or not but afaik avidemux doesnt have this option so i dont know if i should add a deinterlace filter. I guess my question is if anybody is encoding blu rays in linux and what tools,settings, or suggestions do you have/use. Or if you could point me to somewhere with more in depth info for linux blu ray encoding. Thanks in advance.

Use mediainfo (http://mediainfo.sourceforge.net/en), it shows scan type.

What option do you mean? ...anyway, it doesn't matter for subj. You can see scan type in mediainfo, and then choose, use or not to use deinterlace filter (and set the appropriate scan order, - avidemux has this option ;) ).

In general, you can limit yourself with ffmpeg, mplayer/mencoder and avidemux for BD encoding (if neglect subtitles).

Ill check out media info. Megui would tell whether a source was progressive, interlaced, or a mixture of both, can mediainfo do this? also megui automatically selected a deinterlace filter and order, i would have no idea of how to go about doing this without some help if it came up. Also nice to see some fellow gentoo users on here!

HDV is interlaced, and BD is progressive. See?

[donfrenchiano]

Yeah i can see how to tell if its interlaced or not but not sure how to handle it like the field order or whatever, i don't remember what megui said when it added a deinterlace filter. Also ive got a bluray that megui says was a mix of progressive and interlace but mediainfo just says its progressive. Its currently encoding now in avidemux and i just told avidemux its progressive so well see what happens. Im not sure which is more accurate.

[cord-factor]

If in doubt, take some screenshoots from your 'mixed' video on dynamic scenes and look is there fields (interlacing) or it is a 'progressive photo' ;)
However, if you will encode progressive video like 'interlaced' nothing bad will happens.

This is how I do it using all native linux tools. I rip using makemkv (you can use it for free for 30 days to rip blu-rays and buy it if you like it). You can use it on any OS and on as many PCs in your household you want with free upgrades so it seemed like a fair deal to me as it always has the latest in decryption.

For encoding I use handbrake. I suggest high profile if you computer has enough cpu as it gives the best quality for the bit rate. I cannot suggest which RF you should use because that of great debate but the default 20 wont steer you much off. There is also plenty of settings to tweak to your hearts content should you dislike the default profiles.

Handbrake converts the HD audio to AC3 which I don't like. I use mkvmergui to take the handbrake video and the original audio and subtitles then merge them together.

I use XBMC for all of my playback as it handles the HD Audio perfectly on my Asus EN g210 with the exception of only getting DTS core instead of DTS-MA. Some day bitsreaming will work but it looks like their getting close.

You could convert your audio to Flac. That way you would still get the lossless audio but in a format that XBMC can process.
