I like to manually adjust the sound to be consistent throughout my video. I was about halfway through adjusting the sound when all of a sudden the sound wouldn’t play at the volume I had set it to. Every time I restart shotcut it will reset to play at the corrected gain but as soon as I make a change (a cut, lock a track, or add a filter to a clip) it will go back to playback at the source volume level.
I have had this problem before but not so bad that it happens every time I open shotcut.
I exclusively use the gain filter to control sound. On some clips I use keyframes (to normalize erratic audio clips) on others I with use a gain feature without keyframes (for consistently loud or quiet audio).
Also I adjust the gain on clips only. I didn’t know you could adjust the gain on an entire tracks/Master, I will have to look into that.
I just checked the Master & Tracks to make sure I didn’t accidentally add any filters to them (since I didn’t know that functionality existed). Stoked to have a new tool!
I haven’t exported the video yet but I noticed that it the sound issue is not occurring when I only add new gain filters. But only when I lock a track or split a clip. Then I can restart Shotcut to get it to give me a proper preview again. Also I use the audio loudness display and that also reads the source file db level when this error occurs…
It is very strange that you say locking a track can trigger the problem because that is a superficial change and does not touch upon edits or filters. I need to figure out how to reproduce it, and I want to be sure that locking a track really it is a trigger. Are you absolutely certain? Are you sure you are not accidentally disabling a filter by clicking the checkbox or double-clicking in the Filters panel?
You can upload your project file, and I will take a look. Zip it if you want.
Ok, so I exported the file after restarting and the output file had the correct sound levels. It took so long to verify because I wasn’t done editing and had to restart the program every time I made a change. Also since it is such a big file it took a long time to export. For now I will just keep an eye on it and report back if I continue to have the problem on future projects.
So I have been traveling for work and my server isn’t setup yet so I couldn’t test the new version of shotcut until now. But version 18.09.16 fixed my issue! I am very relieved, so many hours into this video.
