Help! 5.0 waveform drawing problem

Kyoto wrote on 7/17/2004, 8:10 PM

I've had Vegas since 1.0, and it's always drawn, in realtime, the waveform of the track(s) I'm recording.

Just started using 5.0b, and when I go into record, you don't see anything being drawn for a few seconds, then the new waveform pops up, and then there is a blank space again between the end of the drawn wave and the moving time marker. After the marker moves to the right an inch or so, the waveform drawns in, all at once, and on and on this goes. Then, after about a minute of recording goes by, the very beginning of the waveform(starting at 00:00:00) starts to disappear, and change into just tiny red and white vertical lines, and as time goes on, more of the waveform changes into this!

What's goin' on here???

I don't have that much history with Vegas but it seems to relate to the amount of CPU load. Freaked me out the first time I saw it happen. But once I stopped recording the waveform was drawn correctly.
I'm still a bit of a newbie to using Vegas for audio recording so I hope there's nothing more sinister to it than that.

This was not an issue in V1, 2, 3 or 4, and there should not be much CPU load recording the first track of a new project!

The red vertical lines have been present as far as I can remember and through several upgrades of my computer systems. This has certainly been the case with Vegas 3, 4 & 5 (I can't recall if it was there on 1 & 2). This is not a cpu issue as my current system hardly ever goes over 20% even with 20+ tracks. The first time I saw it happening (years ago) it kind of freaked me out, but I now assume its just some weirdness unique to Vegas. It doesn't seem to cause problems but I would be interested to hear from Sony what this is about. Unfortunately since one particular abusive jerk ran Peter off of this forum, we rarely have Sony techs replying to these kinds of inquiries anymore. ;-(

When I go into record and no waveform is being drawn for 5 - 10 seconds, I start to worry that the track is not being recorded, and if I'm working with a client doing their lead vocal i don't want to have to wonderwhat's going on.

I don't record anything that critical but I agree it would be nice if it worked better.
How about posting theis in the video forum, at least someone from Sony seems to still drop in there from time to time.

Regarding this issue, I received this from Sony:

"Vegas has always had a fixed internal buffer size for showing wave forms
during record. Basically, the peaks being seen during record are built on
the fly. When the buffers allocated to this are full, the buffer is re-used
and why the solid line appears at points earlier in time. It has always
worked this way since Vegas 1.0."

Evidently Sony is working on changing this in the next version because as this thread has pointed out, the visual aspect is bothersome (although its not a functional problem per se).

Kyoto: What sound card are you using, and what driver model (Classic, ASIO etc)?

Kyoto wrote on 7/20/2004, 8:25 PM

Aardvark Aark 24, ASIO driver.

This is the first version of Vegas that I've used the Asio drivers with. With older versions of Vegas - and drivers other than ASIO - the waveforms would draw flawlessly as soon as you started recording, and never changed to the small vertical line mode.

This may be a related or unrelated issue, but I have also not had success using the Auto Input Monitoring feature of 5.0b. It switches fine from playback to input when you go into record, but the latency makes it unusable.

Thanks for your help.

I agree that this is very bothersome and I sincerely hope they fixed this in future versions. It alwasy freaks my clients out.

I've always founds the red stripes vaguely unsettling, but the blank-gaps between wavform updates in V5 are very disconcerting, especially considering the unassertive 'recording' indication of the the slightly shadowed record button. Something a little stronger here would be more reassuring - like flashing red as per SF.

That's right! You need to definitely know if the software is actually recording!

This problem is on the heels of V3 & 4 having the issue where occasionally you would record a track, save it, and then the waveform would not be there. The .wav file was recorded, but it removed itself from the project. You had to search for the file and manually sync it back with the other previously recorded tracks! (At one point I started dropping a marker every time I went into record so that if it happened, I could retreave and drag the .wav file to the marker spot on the timeline.) I have not used V5 long enough to see if that bug was addressed.

The lack of a glaring RECORD indicator has been a gripe of mine since I started using Vegas (2.0h). I turn off all waveform drawing when I record to conserve CPU . The only indication I have that there is recording going on is the time display. I'm still on 4 - haven't (and might not) done the 5 upgrade.

I've been seeing the "delayed" wavform drawing here and there over the years with vegas, but is consistently happening in 5.0b. True, the real bummer is wondering if you hit the record button for the first 20 seconds or so until the wav decides to show up.

Also...those red lines that show up...not a biggie, frightening at first, but becomes your friend.

my computer is clean and CPU useage is low, no reason for this really.
