Seem to be having bad luck with Premiere recently. Now the latest hassle is that when I change the gain on an audio clip, and go to play it back, there's no sound coming from it. I just cleaned the cache today. any tips appreciated.
EDIT: seems like randomly the program wont play sound from any clip now either...
Bill, heres the audio clip properties.
Type: Windows WAVE audio file
File Size: 19.9 MB
Source Audio Format: 48000 Hz - 16 bit - Stereo
Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
Total Duration: 00:01:48:36864
Average Data Rate: 187 KB / second
I just deleted all the media cache files and let the program rebuild from scratch and I's still having the issue. in fact, after I do the gain adjustment, the affected clip almost looks likes its jittering ever so slightly on the timeline during playback. This has never happened before. I have made no changes to my computer for me to think ti was somethgin I could have done
Per Jim's link, I'm using CS 5.5.2, Mercury accelerated, system is an i5 2500k, gtx 560 ti and 4 gigs of RAM.
The audio meters dont work when playing back.
One thing I just noticed is that I had an internet radio playing in the background and when I did the adjustment just now and playe dit back, the audio from that web browser cut out as well.
Im using Premiere WDM sound in the sound options. I tried ASIO as well and same thing is happening.
Tried that Jim, still nothing. Makes no sense. I have no idea why this would just happen out of the blue. Happens on any sound clip in which i tweak the gain. Ugh. Going to update the Realtek audio drivers, will report back tomorrow
OK So i found out what the deal is. This audio has 2 tracks. I am hilighting both tracks when adjusting the gain. there is no waveform on A2. if I adjust only the clip witht he waveform, it works fine, hilighting both causes the error, but the waveform on A1 doesnt change at all. I dont recall this ever happening prior to recently. Now if I want to adjust the gain, I have to unlink the audio and vide tracks to separately hilight only A1 when making an adjustment.
Glad that you found the cause of the problem.
Regarding the Waveform Display, though you adjust the Gain, the Waveform will not change. It is "baked into" the PEK file, generated, when you Import the file.
Unless we are talking about different things, this entry from Adobe Premiere Pro CS5 Classroom in a Book, Adobe Press, pretty much covers it:
"Waveforms are immutable
Adding an effect to a clip in Adobe Premiere Pro will not affect the original audio or video clip or the visible audio waveform. If you change the clip's volume or apply audio effects to it, the waveform will always display the clips's original volume levels."
Now, if the PEK file (Waveform Display) has been changed in CS 6, then I stand corrected, and that would be a nice addition.
I think you might be confusing volume levels (yellow bar across audio clip) with the gain levels (how high or low the waveform is on the clip.). In cs5.5, any time I adjusted gain on the audio level in the timeline, the waveform gets larger or smaller on the clip to show adjustment.
Now, if the PEK file (Waveform Display) has been changed in CS 6, then I stand corrected
It's been like this for a while now Bill, since at least CS4. When you adjust the clip's gain, the waveform display changes to reflect the change in volume.
