BDMV encoding for anime BluRay authoring?
 

The following query appeared in my mailbox. The admin requests that you do not query for technical advice in PM. That's not what PM is for. The place for technical questions is the forum, where others can share the answer and where other opinions can be expressed.

In my opinion a 1080i anime should be encoded to prevent block noise in large flat areas. For VBR I'd use a target bitrate of 15000 and a max of 24000 at level 4.0, with 1-second GOP size (1 second GOP at 29.97fps is 30 frames, or 25 frames for 25fps PAL). I'd choose level 4.0 for compatibility with a greater number of external players.

Here is a reference table that suggests min/max and other settings using x264 as well as MPEG: https://forum.doom9.org/showthread.php?t=154533

You might get faster results for lossless HD using UT Video codec.

excellent info. Will try the bitrates you have suggested

which ut video codec would be best for 1080i?

I have attached a screenshot of the ones i see in virtualdub.

thanks

Depends on the colorspace of the files you're working with or the colorspace you want to use, and usually the condition of interlace/no-interlace is indicated somewhere in the dialogs if I recall. Then colorspace designations shown in the image are those which you will encounter many times over in your video projects, so I'd suggest that you look up those "YV" values and note what they mean. There's a lot of detail in the ReadMe html file that ships with the codec package. You should always examine documentation that comes with filters and codecs,m if any. Their purpose is to tell you how to use the product. UT Video Codec Suite Typical ReadMe.

Have done some reading and confused lol. Not sure how to interrogate that table you have linked to work out which colour space I should be using.

I am capping from HD satellite feed via HDMI. I was guessing codec ULYO YU12. The only reason for that is I read your post on using virtualdub and you used YUY2 for vhs and I noticed YU12 was the other UT codec you had installed :)

HD capture via HDMI uses YV12 color and the BT 709 matrix, so the UT codec is "UT Video YUV420 BT 709 VCM" (aka ULYO in the document table ).

VHS capture uses YUY2 color and the BT 601 matrix, so the UT codec is " "UT Video YUV422 BT 601 VCM" (aka ULY2 in the document table).

These values assume that during processing you maintain the same colorspace. Note that VirtualDub and other editors convert YUV colorspaceas to RGB for display only if you apply no filters, but if you use any filters in VDub or editors the video is converted to RGB for filtering. To return to the original colorspace you need to specify what you want for output. In that case it gets complicated. You can output to the same colorspace and matrix you started with, but if you are going to encode your final output, note that HD is encoded as YV12 using the BT 709 matrix, and standard definition/DVD is encoded as YV12 using the BT 601 matrix. If you don't use one of those systems for your final output workfiles, your encoder will make those YV12 conversions when it encodes.

Most people use UT codec for HD workfiles and Lagarith for standard def workfiles.

much appreciated.

I have changed the gop to 25 frames but i can't see the level 4.0 you are referencing.

I have attached a screenshot

Encoding levels are set in the "Video" menu, not in the "Advanced" menu.

Can't see it there either. Is it because i have chosen the blu ray preset, i have more options like quantization if i choose to do mpeg-2 sd.

I have attached a ss of the video tab.

thanks

Hmm, that's a change from my copy of version 4. Apparently TMPGenc's version 5 is using an automatic setting based on your choices of encoding type and bitrate, so you shouldn't have to worry about a Level setting.

cheers. Yeah couldn't see it anywhere. I changed the GOP to 25 instead of 15 and will try some encodes.

The GOP size of either 1 second or 2 seconds is recommended by most encoding experts for big-frame HD, even though other sizes can be used technically, but those two choices ensure compatibility with strict BD spec. 1-second GOP looks cleaner during motion segments. If you look at the GOP size on many internet downloads they're encoded at low bitrates with GOP sizes up to 250, and they all fall apart with fast motion or dense detail. But, then, the internet is a pretty shabby source for quality video.
