Audio repeats snippet during preview of cuts?

All,

For any version of VideoRedo after 2.2.1.445, I'm having problems with the audio repeating a brief snippet of the last audio played before the beginning of a cut at the end of the cut when previewing cuts. In searching this forum, I did find a couple of references where others appeared to have a similar problem but haven't seen any resolution (see links below and excerpts).

2. When playing-back to test a cut, a "piece of audio" i.e. an audible click or snippet from the last playback is heard despite that it's not actually in the join.

4) preview playback plays a few samples from the last time a preview was played as if an audio buffer somewhere isn't being flushed properly (does this on mutiple computers with completely different audio hardware).

I would stay with 445 except that I'm having the problem with VideoRedo hanging often after saving and I'm hoping the newer versions will take care of that issue.

What versions have you tried?

What are your system specs? OS + SP, CPU, RAM, video card, audio card?

Have you tried enabling/disabling YUV acceleration and DirectSound in Tools>Options>Playback Devices

Have you also tried selecting a different video driver and audio device on the same page?

Scott, I too have heard the click-or-pop ie. a residual audio bit when previewing. In my experience it exists if you've previously played something noisy i.e. not stopped at a perfectly quiet spot, then you navigate using the arrows to a place where the audio is mute (per the audiograph) and select it (as Start or End) and then Play you can hear the prior snippet. I think you've said this same thing--- ;)

I am one of those who complained about this early-on, but it seems to me the problem has lessened with newer releases, though it's not completely gone. I dunno if it's an audiocard or driver issue (if not VRD) but I have trained myself to ignore the clicks and just go with the audiograph.

If I trust the audiograph, the cuts are indeed perfect i.e. no clicks. BTW when I select a blank/quiet spot to cut, I like to review the frames leading into or out-of the cut, to avoid getting caught by those brief network "pops" in the audio that sometimes occur.

This is a bit uncomfortable to be sure--if there is indeed a "buffer not being flushed" or something hopefully the programmers will find/fix it sometime.

Pat,

Versions without the audio issue:
2.1.0.401-2.2.2.451

Version with the audio issue;
2.5.2.491-2.5.5.512

System specs:
1.0 GHz Pentium III
512MB RAM
160GB and 200GB ATA/100 hard drives
Windows XP Home SP2
Leadtek (nVidia GeForce FX 5900 XT)
SoundBlaster Audigy

I have tried various combinations of video and audio settings in VideoRedo with little effect. I'm using YUV acceleration enabled with DirectX and DirectSound drivers

Note that if I go back to 451 the problem disappears but then I have issues with VideoRedo hanging after saving. (I'm also hoping to use VideoRedo with my Series 3 TiVo when they finally get around to releasing that feature and I think there are some fixes for working with tivo files in later versions).

can ya give just a wee bit more, Scotty?

I have only observed the problelm on slower computers, or with slower links to the source video
(remote computer hosting the video being edited)
My laptop with at 1.5ghz Celeron, is more likely to exhibit the problem than a 2ghz AMD Barton.
My dual 2ghz Opteron is noise-free. :)

You may lessen the problem by changing the sound driver, video driver, freeing up memory, or getting a faster (oh, you have SATA drives!) ...
More CPU speed is needed, I would say.

Annoying though it may be, I've learned to ignore the problem, because nothing ever shows up in my edited output discs.

Mine's a 3.2GHz P4 (Northwood) with (I thought) decent on-board audio. My video card is marginal at best--can a crappy video card affect the audio?

My system is an E6400 core 2 duo and so also well in spec, but I was getting exactly the effect described by laserfan. Choosing 'default WAVE' amongst the options suggested by phd cleared the problem up for me. I have a middling graphics card, a 7800GS, but I don't know if the graphics card is a relevant issue either. YUV acceleration is unselected. (Must try it some time and see what happens!)

See if you can update the audio drivers for your card.

I had a system I was happily using and picked up a USB headset. I tried using that and got the audio hiccup.

I unplugged the headset and reverted to the sound card and all was well again. I installed a driver update for the USB headphones and everything worked well.
