Premiere crashes during render when time-stretching a 12 hour video as 1 un-split segment. I always use the preserve audio pitch setting in Premiere, however I suspect it is not limited to constant pitch resize because Powerdirector has a similar crash issue for long resize, and powerdirector does not have the built in keep pitch function.
The constant pitch audio stretch algorithm in audacity is limited to ~1 hour, it seems premiere's audio stretch algorithm has ahem similar limitations. If I split it to small chunks in the timeline, then my render goes through without crashing (I should not have to do this). I am then able to render it as a 12 hour video with 48x conjoined 15min timeline clips BUT noticeable sync issues occur very quickly: 0s latency at start of the split, 1-3s latency at the end of each split. these develop both when speeding up 45 min video into 15 min video (3s latency at each clip end), and when speeding up 30 min video by 10% (2s latency)
My workaround for the sync issue is manually resizing the audio in audacity, and then resizing the video to match my audacity audio, which is very labor intensive especially because of aforementioned limitations of audacity. Again, I should not have to do this.
There are no sync issues when editing the clips in real time.
As a separate but possibly related issue, there is a discrepancy between Premiere's hour and seconds mark, vs the timeline on every other player and editing software. So I am unable to apply the edits from my notes on the exact h:mm:ss, I have to scroll back to find the frame and offset my edits by ~10 seconds for every hour. I playback source videos on external players to get my edits, and my videos are rendered for viewing on external players as my viewers don't watch my videos from Adobe Premiere. This is especially frustrating when I push duration limits for hosting sites and am forced to build in extra margin to account for Premiere-time.
Have something to add?
