After V4b I'm getting pops in audio with Mpeg2 render...hep me, hep me please!

Randy Brown wrote on 4/15/2003, 9:30 AM

I thought maybe it had something to do with DVDA compressing my audio, but after re-rendering (in V4b) I checked it in WMP9 and they're still there. This has never happened with V4.0.
This project is due tomorrow so I would very much appreciate your help.
P4 2.53
724 DDR MB PC 2700
80gb and 60gb
XP Pro
Delta 1010 sound card (but the pops occur in the same places consistently upon playback...definitely embedded in the file)
TIA,
Randy

I just created an .AVI and found out that they are created there too (in different places than before). Anyone have a clue what could be causing this...like I say, it's not in the .wav file before rendering, it happens somewhere in the rendering process.
TIA,
Randy

Have you defragged lately? Was there something else running that might have disturbed the data flow?
These are simple questions, but pertinent (says my experience).

Thanks Tor,
>>Have you defragged lately?<<
It's showing that I don't need to defrag either of the drives (according to XP defrag).

>>Was there something else running that might have disturbed the data flow?<<
Actually yes, I had a dial up connection (if that counts) going while rendering in the background every time but this has never been a problem before. I'll try again without anything else going.

>>These are simple questions, but pertinent (says my experience).<<
It seems every time you guys solve one of my problems for me, it's a simple solution.
Thanks again Tor, I'll report back later.

Well, I'm getting the same thing with nothing else going. The only thing that has changed is my computer has been networked with my wife's and daughter's PCs but I still get the same results after disabling the connection. I don't know if the rendering process even goes through the sound card (pops in audio were frequently a sound card issue back when I was doing audio only) but if it does which should I select under preferences/audio device. I have the option to select my Delta 1010 using ASIO drivers, Microsoft Sound Mapper, Direct Sound Surround Mapper, and Windows Classic Wave Driver. Any opinions on which I should use. ANY suggestions would be very much appreciated!
Thanks,
Randy

Where is the popping? Is it in a music track? Make sure the music is at the same Mhz as your video track. 44 or 48 - Making sure those match has stopped the popping for me.

Thanks Zorro,
>>Where is the popping? Is it in a music track?<<
It's hard to tell since it only does it after rendering (to a single stereo track)

>>Make sure the music is at the same Mhz as your video track. 44 or 48<<
Makes sense since the music bed is 44K and I have my camera set to record in 48k.
I feel sure there's a way to re-sample one or the other (I'm guessing it would be best to bring the 48k down to 44?) but not sure the best way. Any suggestions?
Thanks very much Zorro, my deadline is upon me :O

I seem to remember a thread on this a while back where it was a driver issue
with the 1010. My friend also had the pop problem with the ATI video card.
Changes card, no problem.

Randy Brown wrote on 4/16/2003, 1:16 PM

Tor, I rendered all audio (MS wav 44/16) to new track; it seems to have helped but there are still pops.

JJK, ironically I just got rid of both of my singles cards (one of them being an ATI) and went with a Matrox Millineum G450 dual head LX. Could this be related?
I am using the latest Delta drivers and have never had a problem with them but...
Thanks guys,
Randy

TorS wrote on 4/16/2003, 1:36 PM

I've not seen the Matrox G450 accused of problems related to Vegas. Delta drivers work fine for me (I have the Delta 66). Have you looked in the Control Panel and muted un-needed channels?
Anyway, good luck. I'll be in Rome tomorrow and then Florence, so I won't follow this thread (nor any other) for a few days.

JJKizak wrote on 4/16/2003, 1:47 PM

I have never hard of any Matrox card giving a pop problem. I am clean out of
suggestions other than the latest drivers with v4.0b being so new, it might be
a driver issue.

Randy Brown wrote on 4/16/2003, 2:05 PM

Thanks for trying Tor. I could be wrong but I don't believe it's a sound card issue since I've never had a problem before my V4b update.

Thanks JJK,I wonder if I should try to reinstall V4.0.
Thanks again guys,
Randy

Randy Brown wrote on 4/16/2003, 4:59 PM

I called SF support and they suggested I uninstall/reinstall but it didn't do the trick. Out of desperation I uninstalled again and installed V4."0", rendered again (for the 9th time) and there isn't one single pop!
Thanks Tor and JJK,
Randy

JJKizak wrote on 4/16/2003, 6:46 PM

Do you have any other sofo software installed other than V4.0?

JJK

Randy Brown wrote on 4/16/2003, 7:11 PM

Yes, SF Noise Reduction 2.0 and DVDA (and V4b).

Do you get clicks and pops on the burned DVD? I have a problem with MPEG 2 video having periodic freezes but burn to DVD looks fine.

Randy Brown wrote on 4/16/2003, 7:32 PM

Thanks WB,
I get no pops when rendering in V4.0, only V4b. I never did burn burn the V4b renders because I got the pops whether rendering to DVD, AVI or WAV. I'm thinking it's related to V4b since I tried many renders with the same results with V4b and no problem with V4.0.
Thanks again,
Randy

There were some threads on the following install problems with V4.0b, Acid 4.0.
and soundforge 6.0. Seems some of the newer MPeg2 file and MP-3 files were slightly
different in the binary count and would conflict with the older installed files
of sofo software, all products that use the mpeg2 codec, mp-3 etc. When installing
v-40b make sure all sofso stuff is gone from hard drive and including the plugin
files then install v.04b . Then install the other stuff. This might work. I
believe the threads were on the sofo forum in the sound forge older threads. This
may or may not help but it might be worth a try.

Definitely worth a try!
Thanks JJK,

Has anyone found a fix for this yet? I am getting pops when rendering to .avi in 4b. This did not happen with 4.0. Sounds like rice krispies.

Randy,

Did you find a fix for 4b? Did you stick with 4.0? I am having the same problem and like you, the deadline is upon me.

a) How can we reproduce this?

b) Were the projects created entirely in 4.0b or did you start them in an earlier version of Vegas?

prairiedogpics wrote on 4/28/2003, 1:46 PM

I use Vegas 4.0b with a Delta 1010 soundcard with latest drivers. Since I don't do audio recording (yet) with Vegas, I use "MicroSoft Sound Mapper" as the default audio device in Vegas. I rendered a 1 hour 30 minute MPEG2 file for use in DVDA yesterday, and the stereo AC-3 track was fine. (Not trying to make you feel bad, just wanted to let you know my experience with this setup.) Windows XP Pro.

bakerja wrote on 4/28/2003, 1:46 PM

Created entirely in 4b. I did not have the problem with 4.0. I'm thinking of deleting Vegas and re-installing 4.0 just to see if the problem goes away. I have multiple fx. 2 graphic eq's, reverb with envelopes, smoothness, compressor. Like I said earlier, it plays smooth as silk from the timeline but every render produces pops. Not at any given point, I can do two different renders of the same material and the pops will be at different places.

Thanks,
JAB

I am using Soundblaster Audigy Platinum 2 with ASIO drivers. I'll try this evening to use microsoft sound mapper and see if it makes a difference.
