Help with MPG video encoding
by Walter Belhaven 20 Apr '13

20 Apr '13

Hi, I've got a question on how to get the best possible MPG encoding of a movie source, "at any price" so to speak -- i.e., as many bits as the encoder needs to get the highest possible video quality. It appears to me that the MPG encoding process is introducing artifacts that are present regardless of the amount of "free reign" I give to the encoder with respect to quantization, bitrate, and the like. My bottom line question is thus: "Are these artifacts inherent in MPG encoding, or am I just not twiddling the knobs and dials on the encoder correctly?" Here's all the details ... My source is a mixed hard- and soft-telecined "movie" at 1080/60i that I'm trying to tanscode to 480/24p, soft telecined to 480/60i, for ultimate burning to an NTSC DVD-Video. When I use mencoder to inverse telecine, crop out the crud, expand back to the original letterbox ratio (it's 2.35:1, not 16/9), and 'encode' the video with HUFFYUV (422P), the resulting video looks stunning, with no 'blocking' artifacts to speak of. This, of course, is as expected. But when I encode the video in MPG2 or MPG4, even with vqscale=1 or vqscale=2, I see sometimes severe blocking in the resulting video. Is this because the chroma is being subsampled vertically and horizontally (4:2:0), or is it because 'vqscale' is (perhaps necessary but) not sufficient to get "maximum quality at any price" encoding? Thanks, WB ____________________________________________________________________________________ Be a PS3 game guru. Get your game face on with the latest PS3 news and previews at Yahoo!

B-frames and GOP with MPEG-2 for DVD
by Nicolas Hesler 16 Apr '11

16 Apr '11

Can anyone offer any input to the following command line? I've been trying to refine for the highest possible quality of MPEG-2 while staying DVD compliant. The source is 24fps. (Note: format=mpeg2, because format=dvd does not work with Adobe Encore 2.0). From what I understand, keeping GOP open, improves quality. Is this true? Is it 100% DVD compliant? Do I want to introduce B frames in my encoding? (The vb_strategy part of my command line is currently useless, right?) If parts of my video are reaching into 9-10 Mbs bitrate, would it beneficial to introduce B-Frames? Will it improve quality? (This is probably a stupid question) Are the sync issues with bframes only relevant to mpeg4 or lavf? mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=mpeg2:tsaf:telecine / -vf scale=720:480,harddup -mc 0 -noskip -srate 48000 -af lavcresample=48000:0:2 -lavcopts / vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=7000:vbitrate=6000:keyint=12 / :trell:mbd=2:precmp=2:subcmp=2:cmp=2:dia=-10:predia=-10:cbp:mv0:vqmin=1:lmin=1 / :dc=10:vpass=1:vb_strategy=2:acodec=ac3:abitrate=224:aspect=16/9:vstrict=0 -ofps 24000/1001 -o $output $input

2pass: auto-calculation of bitrate?
by Ilya Zakharevich 25 Nov '08

25 Nov '08

I'm looking for a way to let mencoder (I use xvid) to automatically select the 2-pass average video bitrate based on the contents. I'm pretty sure that most (if not the all) of the logic to do it is already there, but I can't find the UI to trigger this behaviour. A) For example: suppose I have 100 videos; now a) append them all together; b) do 2-pass encoding of them all with, e.g., 1200kb/sec bitrate; c) split the result into 100 video files. This way, mencoder will automatically assign some "appropriate" average bitrate to each video. B) Now suppose that I have only 1 video, but I have all 100 logs of pass=1 for all 100 videos. Theoretically, this is all which is needed to do an equivalent of a/b/c for this particular video. How to convince mencoder to use these extra log files? C) Now suppose that I have only 1 video, and only 1 log of pass=1 for this video. It is more or less obvious that all I need from the remaining 99 logs is very short "summaries". How to create the summaries, and how to "feed" them to mencoder? D) And now the last logical step: If of these 99 remaining videos 40% is "action-like", 40% is "arthouse-like", and 20% is animation, then law of big numbers starts to be applicable. Essentially, I won't need to have summaries of the particular videos; I could feed in 40 copies of "average action-like summary", 40 copies of "average arthouse-like summary", and 20 copies of "average animation summary". So if I keep these summaries in ~/.mplayer in action.sum arthouse.sum animation.sum, then I could ask mencoder to do bitrate_from=1200,40*action+40*arthouse+20*animation and it could choose the appropriate bitrate. Is it possible to do now (possibly, with some pre-processing)? Any plans to have this? Thanks, Ilya

Re: [MEncoder-users] RM to FLV file bloat - huge upsize
by David Smith 28 Jun '08

28 Jun '08

So how do I read the bitrate of the RM file going in so that I do not unintentionally upsize the bitrate and create an unnecessarily large .flv result? I will say, however, that some of the other RMs I've converted had high bit rates to begin with, but still resulted in extra-large flvs. Thanks. > > > > ---------- Forwarded message ---------- > From: RC <cooleyr(a)gmail.com> > To: MEncoder usage discussions <mencoder-users(a)mplayerhq.hu> > Date: Fri, 27 Jun 2008 12:55:12 -0700 > Subject: Re: [MEncoder-users] RM to FLV file bloat - huge upsize when > converting > On Fri, 27 Jun 2008 13:03:04 -0400 > "David Smith" <dcsmith2(a)gmail.com> wrote: > > > How come the Flash file becomes so huge after converting the > > RealMedia?

RM to FLV file bloat - huge upsize when converting
by David Smith 28 Jun '08

28 Jun '08

I am using Mencoder command line in my application to automatically convert RealMedia (.rm) files to Flash (.flv). How come the Flash file becomes so huge after converting the RealMedia? The video and audio quality are just fine but the file bloat is crazy, like 3-8x's the size of the original. Even an 18Kb test file gets blown up to 94Kb. I have attached the output for that particular conversion, as it is very representative of the larger files I'm working with. This is my argument string: -of lavf -oac mp3lame -lameopts abr:br=56 -srate 22050 -ovc lavc -lavcopts vcodec=flv:vbitrate=300:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -vf scale=320:240 I am not trying to do anything funky here. These are pretty standard bitrates and file dimensions. I do not have this trouble with any other file formats. This is a big problem because I have to pay for storage and bandwidth use, so anything that converts UP is no good. At a minimum I would be happy with a theory as to why RM files do then when converted. But a fix would certainly make my day! Thanks for any insight. By the way, since this needs to be an automated processes I cannot use any client converter programs.

x264 Too many video packets in the buffer
by Lionel Gattegno 26 Jun '08

26 Jun '08

Hi all, I'm trying to encode to h264 from TS mpeg. I've got tons of "Too many video packets in the buffer" and "Skipping frame!" messages during encoding. I'm using -cache 65536 parameter and vbv_bufsize=1835 option in the -x264encopts parameter When playing the video, images sometimes stop while sound continue. Any idea? Thanks
