Audio Issues with my files

[derekwc]

Let's see...

Most of my files (not all) seemed to all go out of sync for no particular reason
a few days ago.

At first I thought it was just the Tivo.files. It was them, but I tried resending
them thru Tivo to go. No Dice. I started using my tradtional Tmpgenc method
for making MPGs. The MPG audio was out of sync. In most files they would start out fine but get loopier. I converted the audio to WAV. Still the same issues. I tested some other files, avi's dixv etc no dice.

I think the only files that seem to be working are the AVIs that I captured striaght from the Canopus. Even then now I'm getting driven slowly crazy
by watching similar clips over and over to see if they stay in sync or not.

Anybody know what this might be? Is Tivo trying to drive me crazy?

I had some issues recently (before this) and had to redownload certain codecs. The end result was my Windows Media could import video and
TMPGenc could make MPGs out of TIVO files (which for the time being was all I cared about). However for some reason my PowerDVD player refuses
to work properly and I kept having to delete any FFdshow and MAtroska
files as they messed with the above somehow.

Anyway I'm at the point of giving up alltogether, but I thought I'd give
this an ask before I gave up.

Sorry if I'm not very detailed (I had just had my routine set and everything worked just fine--but then somehow certain codecs and things
seem to refuse to work and now most of my video files seem hard to
jump to--from point to point--or plainly they get way out of sync).

Thanks for reading.

That type of sync loss is usually because of the length of the audio and video differ. Check and compare the lengths.

If they are exactly the same, then it's a likely a playback problem. Could be codecs, but it sounds more like a OS problem. Try VLC player as it uses it's own codecs.

I would run a thorough search for trojans, viruses, and the like. Check your hard drives also for fragmentation or corruption.

Did you change anything in the OS or the computer recently?

Try a restore to a date before the problems.

Check for background programs running that might be interfering. The Task Manager should tell the processes and programs running, along with memory and CPU usage. You can type 'msconfig' in a 'Run...' window and control what processes are running.

That's a few things to try, anyway.

The audio seems to be on a delay by 2 seconds.

The tivofile is 30:03 and the audio/wave is 30:01...

Can that even be fixed?

And thanks for all the suggestions BTW

If I'm reading your numbers correctly, that looks like a 2/10s of a second difference. But if it is 2 seconds, you could drop the audio into an audio editor and stretch it that much. Even the freeware Audacity should be able to do that, or Goldwave, etc. If the audio/video start times are offset you can add or subtract a offset with the same type of programs. Offset is the other common type of sync error.

You might want to check that file for errors also. It may be missing part of the video or audio.

Thanks again for the suggestions.

The audio is 2 seconds out of sync according to the numbers. It's bad enough
to distract from any enjoyment in watching...

I'm not at home now, but I'll try your stretch suggestion when I get home.

Just wondering why this would happen now with certain Tivo files
rather than with all tivo files all the time???

How would one actually go about stretching the audio with Goldwave?
