FPS too high for Mencoder? Help stattik!

[wintermute]

stattik, Can you help?

On and HDTV recording (recorded straight to an mpg file) that was 6.4GB for a one hour show I attempted to run mencoder. It kept flashing through it, exiting and creating a 0KB mpg file.
I ran the option manually (see below) and it was erroring out (see at the bottom of the results). What is causing that and can I correct it for the HDTV recordings that create a larger file? It appears that the mpeg2video cannot handle the higher fps. Can this be adjusted/fixed?
Thanks

there has been a known problem with mencoder and large files before...tho may be unrelated
may want to check out another version...i still can't do a network path that's larger than 4 gigs...[they never fixed that] so i now use ffmpeg cuz it has no problems with sizes or net paths..
[plus, i say the quality is better,same options]
you've got the SSE one...don't use any versions that have SSE enabled..it messes up the encode and has that bug in it for sure...
[and trust me the isn't any speed difference]
get the one from the mplayer page that is for amd...more reliable..
and possibly specify the fps on the command line...-fps for input, -ofps for output..
hope that helps..
i know there are filters that run at doublespeed[60fps] so it should be able to handle it..

[pBS]

oh and also i notice you don't have any interlacing switches in there..
unless the source is coming from a dvd,then it need interlaced support...
use in -lavcopts 'ildct' at least, and 'ilme' if you can stand the speed decrease..
just a thought..i always use them...

This is the mencoder version I am using currently from mplayer's site.

Source is from an HDTV broadcast using a FusionHDTV 5 USB Gold.

I'm testing this out and will have more info later. Are you just trying to trim the commercials from a HDTV broadcast or are you trying to make the HDTV broadcast DVD compliant? There's a few things that need to be tweaked for the latter to happen.

[wintermute]

Thanks for your response stattik.
Initially, I just want to cut the commercials out. However, I do want to create commercial-free mpg files that I can burn to DVD later for archival and later play on other systems/set top boxes.
Additionally, I want to be able to reduce the quality/file size for play on older systems and set top boxes as well as to be able to put a two hour show (13.8 GB in HDTV 1080i right now!) on a single DVD.

Thanks stattik!

Well I did two tests, both with 30 seconds of 1080i @ 29.97 FPS

These were the outputs:

(1) 1080x1920 with 5.1 AC3 audio

(2) 1080x1920 with 2.0 Mpeg2 audio

Both played fine in WMP using the Dscaler5 0.0.6 video decoder

Mencoder handled the files just fine. Here's the settings I used for both:

Code:

start /low /wait %mencoder_path% "%~dpn1_original.mpg" -edl "%~dpn1.edl" -oac copy -ovc lavc -of mpeg -mpegopts format=dvd -vf pullup,softskip,harddup -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=%mpegbitrate%:keyint=18 %test% -o "%~dpn1.mpg"

Code:

start /low /wait %mencoder_path% "%~dpn1_original.mpg" -edl "%~dpn1.edl" -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -vf pullup,softskip,harddup -lavcopts acodec=mp2:abitrate=128:vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=%mpegbitrate%:keyint=18 %test% -o "%~dpn1.mpg"

I used a 11-23 compile of mencoder for Athlon XP processors which can be found here:

http://ffdshow.faireal.net/mirror/mplaye...hlon-XP.7z


On another note, a completely new MPEG muxer was committed to mencoder CVS a few days ago. I haven't tested it yet but it may be worth looking at.

[wintermute]

Thanks stattik, I will follow your suggestions and give you an update.

[wintermute]

stattik,

I tested the mencoder script :
start /low /wait %mencoder_path% "%~dpn1_original.mpg" -edl "%~dpn1.edl" -oac copy -ovc lavc -of mpeg -mpegopts format=dvd -vf pullup,softskip,harddup -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=%mpegbitrate%:keyint=18 %test% -o "%~dpn1.mpg"

And my results (so far) are it is VERY SLOW in processing (see below).
It looks like the frame rate is LOW from the output.

Any ideas? I am using the 11/23 mencoder compiled for AMD XP.
