$ sudo lshw -sanitize -class cpu -class multimedia Perhaps this is a thread scheduling or priority (or CPU capacity) issue in the application given the newer operating systems?Ĭase 1 - oldest system - nice sounding audio but rapidly looses sync with the video: upgrading made improvements in the playback. The newer the chipset the better the audio. The older Intel audio chipsets have progressively worse trouble with sound (on the newer operating systems), but the oldest, with the faster CPU, didn't have the playback noise, only the sync problem. Notice the progression (I tested several systems since the last posting). I think this has to be AviDeMux or maybe both the application and the drivers.
Then, as a video was playing, I drug the window around with the mouse, leading to substantially increased audio noise!
the original upgrade) on the problematic system) the "default" device for ALSA cleaned up the noise and distortion to the point that it was more usable than my Pulse alternative (that continued to have dropout beats every few seconds).Ģ. When André said he had similar problems with OSS and SDL (I didn't), I really began to suspect AviDeMux, even though, initially, I just swapped in the new OS under the application.īut perhaps the newer OS (both Intrepid and Jaunty) just were less efficient, exposing the problem?ġ. But since all other audio systems had no similar problems, I suspected AviDeMux - perhaps exposing a problem lower down the stack, or just mishandling it (more likely). Since everything worked before Intrepid, I though it might be either drivers, specifically, or systems integration (Ubuntu), in general - wasn't that the switchover from ALSA to Pulse?Ģ. All of the systems I have to work with (both laptops and desktops) have the on-board Intel audio chip sets, and this trouble seems to affect them all, though the degree of the trouble varies.ġ. So, somehow, this really does seem to be a problem, as I no longer have a complete work-around.
All this started with Intrepid and follows through the same way in Jaunty. I could not work with the noisy audio at all. I had to use Pulse Audio to clean up the sound while working, except that, now the sound "pulsed" (no pun intended) - the sound drops out briefly about every 2 seconds - like clockwork! I can at least work with that, because, the final renderings are unaffected. While that got rid of the original "trouble initializing." problems, as you said it would, it did not provide useful audio for me while working - I got very "noisy" unstable sound. Thanks!Ĭomplete name : \CapturedFiles\Encode_12_1.Actually, I just tried your suggestion -> going back to ALSA with "default" typed-in in place of "dmix" (as there is no drop-down to choose it, like with the other options).

The other 4 are fine, and all of the MP4's, including the one I'm having issues with, play fine outside of HitFilm in whatever player Windows uses.Īny ideas on why the sync issue is occurring? Any suggestions on how to fix it? I've included the output of MediaInfo in case that's helpful to anyone. With the next one however (5 files) one of the imported videos has an audio sync issue after being imported in the project the audio lags behind the video by several seconds. My first project went fine (3 files composited together). That's what I'm using HitFile for, to "join" these 2GB chunks together (and to trim up the beginning and end of the videos). Longer captures will be split into 2GB chunks.

Captured MP4s have a limit of 2GB (which for the 720p 59.94 FPS content I'm recording, is 15-20 minutes).

It's a pretty simple device just push the button and it records the input to a MP4 on a USB device. I have MyGica HD Cap X-11 that I'm using to capture some video with.
