Megui and commercial cutting sync issues

[eastfamily]

Hey guys I have been using Megui for a long time now but have never really posted too much here. I upgraded to Windows 7 and for some reason, the OnAir GT USB that I have been using has become useless in their own program. So now I am using media center with said tuner and also an Avermedia Duet to get my tv recordings. When I input the MPG's, everything is good and in sync. But when I cut commercials and use the BeSplit plugin for the audio cutter, the audio is out of sync with the MKV produced.

When using BeSplit it chops it into multiple segments, so I can manually mux each segment in and set the delay properly to sync the files but that is way too time consuming.

Does anyone else have this issue with converted video files and the sync getting worse the deeper into the file you get? How do you guys with experience fix this problem?

Using Audio Cutter (MeGUI Tools)
If you have an audio stream, with the initial delay, if any, corrected (use DelayCut), BeSplit must join the segments without noticeable sync problems.

the problem is, it would seem that every clip has a different delay after the cuts. The first clip is perfect, the second is just a little off, third is worse, and so on.

Just curious what is causing this issue

Strange. Edit the .clt file to see if the video Framerate is well detected.
Verify the equivalent time of cut frames with the time values sended to BeSplit (see the log).

Work fine with my test.

@eastfamily i never had any oos with BeSplit...can you describe in detail what exactly are you doing?

Record Tv via WMC in Windows 7. Take the WTV file and convert it to MPG via DVRMSToolbox.

Input the file into Megui and use DG Creator to get the file going. Use AVS Cutter to cut commercials from file, then use Audio Cutting which uses BeSplit to cut the segments. I'm using BeSplit v0.9b8.

The File generates one file for the cut audio, as well as little cuts for each section of time frames that I input. I convert the MPG to RAW H.264 at around 4096Kbps ABR. I don't use Megui to convert the audio anymore at that point as I want to use the 5.1 AC3 at the highest original quality.

When the file is converted I mux the H.264 and AC3 into an MKV container. If I use the single cut file that contains all the show, as the show gets further along, the audio is worse out of sync. Does it for every show I try to convert.

However I can use the little files and mux in one at a time and see where the right amounts of delay fixes things (I use MKVMerge for this).

I would much rather just be able to encode the file, mux it together and that be it. Each show takes half an hour after original encoding because I have to find the right delays.

I don't see it being a problem with my original recordings, I always check the file in AC3Fix and they appear to be good files with no bad frames.

Oh yeah, when I use AVS Cutter, i normally use the "Fade" setting because it is recommended. Is that the possible source of my problem? Maybe the version of BeSplit I am using? Is there a newer or older version that works better?

Thanks for all the help guys.

Maybe you have a invalid ac3 file with a mix 2.0 (commercials) and 5.1 (movie).
Use DelayCut to split the ac3 file in valid ac3 fragments and join the 5.1 parts.

BTW, I have only BeSplit v0.9b7, where I can get BeSplit v0.9b8?

About Fade:
The last frame of the video becomes almost-but-not-quite black (or the specified color). An additional perfectly black (or the specified color) frame is added at the end, thus increasing the total frame count by one.

FadeIn0 / FadeOut0 do not include the extra frame

And to cut commencials you don't need Fade

the "fade" settings in avs cutter is the problem...change it to "no transition"...

for demonstration purpose do a cut using the "fade" setting...open the resulting .avs and add as the last line "info()" [without quotes]...play the .avs and you will see the first line like "frame x of y"...post it here...

now do the same cut using the "no transition" setting...open the resulting .avs and add as the last line "info()" [without quotes]...play the .avs and you will see the first line like "frame x of z"...post it here...

tebasuna51 that was faster...

How would I do so using DelayCut? Never tried to do that.

If you want v0.9b8 then go ahead and shoot me an email.

good news! It worked. Sort of. For some reason the amount of delay was off. But the entire audio file itself was right on the money once I took out the "fade"

Congratulations!
I put a feature request to MeGUI about that.

Don't put your email (delete it) in public forums, to share info use webs like http://www.sendspace.com/
Upload the info and put the link. Thanks!

Here you go. Hope this helps. Not sure what the differences are.

Thanks!
I never know this last beta and is just a bugfix to solve a problem reported in my first post in this forum:

I wish that the program wasn't abandoned and development was still active. If I had any idea how to write code I would.
