Nasty Beep when joining

[DarkShadow]

I have a problem when I join mpeg files with tmpgenc they give a loud beep at the exact spot they are joined other then that they are perfect picture and audio so how would I go about fixing this so when I join they don't give that beep.

My process incase it matters:

Record with VirtualDub at full quality Mjpeg > 7 gb in 2gb chunks
Direct stream copies to get rid of commercials > 5 gb in 2 gb chunks
Encode chunks to VCD with tmpgenc > 3 chunks equaling roughly 420 mb
Join into 1 file with tmpgenc > 1 file 420 mb


When I have the chunks of avi appended in virtualdub and hit play it plays flawlessly with video and audio so it is not the recording since the beeps only show up when they are joined at the end

I forgot to mention that I did do a search through the forum and tried the bit where the second clip is started a second into it but that also didn't work.

I tried another joiner but it was worse the first second and the second after the join the grapghics where messed up (but the sound was perfect)

This shows me that the sources are fine but I just have to find a joinner that works perfectly

I believe M2Edit is fairly popular for MPEG editing/joining. It isn't free though.

Now this won't help you with your current problem, but in the future, what I would suggest is editing out all of the commercials in Virtualdub at once, then frameserve it to the encoder rather than saving each edited block to a new AVI. This way, you get one continuous stream from the encoder, and don't have to worry about joining at all.

I have tried to frameserve but everytime I try it just crashes tmpgenc

[DarkShadow]

I got frameserving working but I don't know if I like it since it is hard on my system and take an extra 45 minutes to get to the same end result. Plus if I am doing multiple shows I can't set up a batch encode which means I can only do one will I am sleeping

[smokin*1]

Just so you know, you can open up multiple instances of VDub. Edit out the commercials from each of your AVIs and set each instance of VDub to Framserve. Then set up a batch encode in your encoder of choice.

Hope this helps

The nasty "bleeeeep!" is definitely because of TMPGEnc's mediocre Joining feature. I had the same problem until I discovered VirtualDub's ability to delete SELECTED FRAMES in a entire video (including videos with more than 2 segments).

First load all your segements, VirtualDub usually loads all the segments when you select the very first segment. Then go to beginning of the commerical break, hit the <- button in VirtualDub, then go to the end of that same commerical break and hit the -> button. Now you will notice the entire portion of that commerical is highlighted dark on the time position bar. Simply hit the DELETE key and now that commerical is gone! VIOLA! Do the same for other commericals. After deleting all the commerical and unnecessary video, simply frameserve and encode with your desired encoding program. =]

* This is very helpful since you don't have to re-save your commerical-free segments using VirtualDub's Save Avi + Direct Stream Copy. =] *

-- Just for the record, before I discovered this wonderful method of deleting frames in VirtualDub, here's what I did to get rid of the "Bleeeep!". After joining the files with TMPGEnc (and hearing that nasty sound), I would simply then De-Multiplex the Video/Audio and then use Sound Forge (or any Audio Editing Program) to mute/silence-out the "Bleeep!" noise and then Mulitplex Video/Audio back together. Yes a big hassle, but it got the job done. --

Jeomite that is exactly what I do know with the frameserving

I thought it was just me who got the bleeps when joining!

Through trial, I found that you need to trim back to before the nearest second, so if you're trimming frames and the clip is timed at 0:05:23, you'd need to go back enough frames to make it 0:04:96. Making it 0:05:00 won't work.

To avoid losing any footage right at the end, I just allow a few seconds at the end of whatever I'm capturing. Join as per normal, then clip a few frames. After a couple of tries, you'll get the knack, and the trimming is seamless.

While this isn't a perfect solution, it does work for me.

[kinneera]

Someone once investigated more closely and apparently determined that the bleep is because TMPGEnc compresses all of the audio from whatever would be the last full second into whatever fraction of it it is attempting to cut to. That is, if your cut point is 0.1 second after the last complete second, the other 0.9 also gets crammed into that 0.1. So your solution is consistent. What I am curious about is if you are always able to get it to work easily? TMPGEnc is only a GOP-accurate cutter, so it seems like there would be times where you would have difficulty actually getting it to cut so close to a given point in time.

[pyrosecht]

why not just keep them seperate and your vcd will have "chapters". Whenever I capture a television program I just open the avi in TMPGenc and use the source range to encode the pertinent parts (get rid of commmercials etc.) Then just burn them with NERO and make sure you change the delay time to zero for each track and you'll have a VCD without commercials (nice fade in and out too) and makeshift chapters. I find this works best for me. Of course I've never found any value in frameserving either but others swear by it.

Thank you, kineera, I do believe that was me. I know I've posted that info before in another thread.
When both cutting and joining, the entire frame's worth of sound is smashed together, resulting in this beep. If you were simply editing commercials, I don't believe you'd be getting these, as the audio would be silent, so I'm assuming that you are just making segments of a film.
What I do is firstly, I try to end the mpg at a spot that is relatively quiet in the first place. Then, when encoding, I use the audio tools to mute the volume at the end at 100-200 ms. (The second one works on its own, but it's less noticeable in quiet spots). This usually eliminates all beeping for me. Good luck!

I wouldn't use the word 'easily'. as it can be maddening trying to cut the bleep out at just the right point, but after a few tries I can pin it down.

Wish I'd thought of trying the 'fade to silence' method, though. I'll give it a go.

I had 3 parts of a mpg film that I wanted to join. When merging under Tmpenc2.53, I got the beeps... Here is my trick to get rid of them...

1) I opened the 3 audios files in soundforge5b and once there, I maked some sound tweaks then I joined them there.
2) I exported the final audio in .wav...
3) Under tmpenc253, I re-encoded the final .wav into .mp2 /4410/224bps
4) Finally,under tmpenc253 again, I merged the 3 videos files (.m1v) then multiplexed the final video with the final audio file and...

Bingo!!

Bonne chance!!
