weird VIDDLL sound behaviour /bug?
Mar 24 2020 | 8:46 pm
Hi dear Maxers!
I am preparing some lectures, I wanted to show to my students how to trigger videos and I noticed a weird behaviour while using the VIDDLL engine:
I had 3 videos loaded in 3 movies and I randomly triggered them via (frame 0,start) message, after I while I noticed a weird volume balance and I recognised that some videos went up with their volume. After some testing I heard sometimes some double triggering of the audio content and I had the feeling the jit.movie was randomly stacking up / loading more the one audio track per video (but this is just a feeling)
I also recognised that if loading the same video in the same moment in 3 jit.movies the sound problem happens (at least on my computer -16inch MacBook latest macOS [10.15.2], latest MAX [8.1.3])
patch:
- Mar 25 2020 | 5:28 pmsounds to me like it's simply the audio tracks adding together which makes it sound louder. if you want more control over the audio, use jit.movie~
- Mar 25 2020 | 7:05 pmthanks for the answer Rob, Yes surely they are sounding louder when played all together after load, but I am not referring to that. If you turn ON the metro on top of the patch the movies play one at the time, there I can clearly hear that the first movie sounds normal, the second louder and the third way louder.
- Mar 25 2020 | 8:29 pmI am routing back the output of my computer and checking the amplitude of each single video, as u can see the second and the third are getting louder
- Mar 25 2020 | 10:40 pmweird, i can hear it now. i'll take a look.
- Mar 25 2020 | 11:16 pmThanks a lot Rob!!!
- Mar 26 2020 | 1:17 pmI started using the jit.movie~ as I need to interactively and continuously change the rate of the video and it seems jit.movie~ behaves the best in this situation. I noticed an other curious behaviour thou, maybe this is related to the previous problem and can help? check out the attached video
- Mar 26 2020 | 4:20 pmthanks for the video but the best way to get this addressed is to send along the patch and movie file you used. can send to me privately if preferred.
