Muxing woes!

[jaycun]

Is there ANY software that can mux audio and video without screwing up the video??

I've spent the last six hours trying figure out how to solve this. I've used both QuEnc and HCEnc. Both produce the exact same _horrible_ results. The moment audio is muxed into the video stream, there are gigantic tearing artifacts on every moving edge in the video.

I am encoding an interlaced NTSC video at 8000kbps (with all the other "high-quality" settings (except Trellis) that each program offers).

AC3 audio is encoded from WAV source at 446-640kpbs (QuEnc and HCEnc respectively). With HCEnc, I tried using Muxman, ffmpeg, and mplex to mux the AC3 file and the m2v file. All the programs produced the same output (tearing).

Has anyone experienced this before? How can these issues be solved?

How are you viewing the muxed file?

Try loading it into DGIndex to see if the video is really screwed up. I think it it must be a player issue.

Now I am baffled.

I was playing the video file in Media Player Classic with the K-Lite Codec Pack installed. I had burned two DVD's of these videos and both came out bad (the burning program that I used was Sony DVD Architect 4.0 and it also exhibited the same problem that MPC showed).

However, when I brought the videos over to my linux system, they played fine (with the exception of players using the xine engine because the audio cut out about halfway through.) Mplayer and VLC work fine.

How does a player have anything to do with this problem? Could it be the fault of K-Lite? I'll need to try my other players in Windows.

BTW...thanks for the program....Next time I'm on that machine, I'll use it to look at the videos.

Don't install codec packs. They often screw up your system. Only install the codecs you need. Or use a player with build in codecs like VLC or GOM player.

Media Player Classic uses DirectShow for playback. It's perfectly possible that your DVD Burning Software also used DirectShow to read/decoded the input files before converting them to the DVD format. So if you have some DirectShow filters installed, that screw up the decoding of your videos, that might explain the playback issues as well as the burning problems...

In order to preclude Codec/Filter problems under Win32, try to avoid DirectShow and play your files in MPlayer for Windows or VLC Player...

well....these movies are being encoded for DVD (a project for some friends....I'm not going to be watching them).

I've never had a problem like this with codecs before. I think the DirectShow explanation is very likely what happened.

Anyway....about K-Lite....I only have the codecs that I use installed...not the whole pack (I normally don't install codec packs, but K-Lite has most of the tools that I would have installed individually in one install file).

I used the ffdshow configuration frontend to take over the playback of MPEG2, and viola, the video plays fine in all players. I'm going to test another DVD later today.

Thanks for the input....I'll write what happens.

Ok....here's the results

I burned another DVD. I pop it into my family's DVD player, and I get the same artifacts as before. Depressed, I pop it into my computer again. Windows asks to play the DVD and I just click Ok. DVD player opens up and perfect video plays! I'm confused

The DVD video is compressed at 8500kbps with audio at about 640-800kbps. What I'm wondering is if my DVD player is unable to handle the bandwidth required to display the video....thus the artifacts. Does piping the video through composite video have anything to do with it? If so, how would I make the video composite safe?

Hi!

1) You might want to run a DVD/CD cleaning disc on your standalone player. Maxell makes one that sells for approximately $10US

2) Burn at a lower speed (4X or, possibly, 8X)

3) Use high quality burnable media (Verbatim, Taiyo-Yuden ["T-Y"], etc.)
