Hi! I received help here several months ago after trying out Shotcut for the first time and having a frustrating time. Back then, the problem was basically that my computer - a Lenevo Think Pad - is not suitable for making videos. After simplifying my concepts though, I have been able to make videos, even though the app often freezes, crashes, or becomes unresponsive. But as I understood it, my computer simply can’t handle the volume of data transfer sometimes and it gets stuck. There’s nothing to do but close Shotcut and open it again and start from where I last reached.
To date, I have made a dozen videos which I have posted on YouTube, and they range from around 19 minutes to 39 minutes. They all are comprised of a single video track which uses video or stills, and an audio track which may use recorded audio from my iPhone or DSLR, or music files from my iTunes library. While problems regularly occur during the video creation phase, there has been no problem exporting videos other than that it takes a very long time on my computer.
Today I tried to export a 24-minute video but at 39%, the export progressed no further. I tried again but only reached 40%. I resized some of the still photos in order to decrease the data, but I only got to 41%. I restarted the computer and tried again but only reached 41%. For a fifth and final attempt, I cut off the final 8 minutes from the video and tried to export the first two thirds as one video. Once again, 41% was as far I was getting. There is nothing different in this video that any of the others. I am doing the same things as always.
I checked the “job” log and noticed the following.
This part seems to indicate that the exporting is going normally.
[h264 @ 03085ec0] Reinit context to 1920x1088, pix_fmt: yuvj420p
(I used to use a larger video size but then one day my camera kept stopping recording after a few minutes, so I changed to a smaller size. My first Shotcut videos were done with larger files and without export problems.)
This line repeats over and over until…
This part. It seems to indicate a problem with buffering.
[producer avformat] audio: total_streams 1 max_stream 1 total_channels 2 max_channels 2
[producer avformat-novalidate] C:/Users/Editor/Videos/Music is a Journey/Episode 10/MVI_4793.MOV checking VFR:pkt.duration 1001
[h264 @ 03086740] Reinit context to 1920x1088, pix_fmt: yuvj420p
[h264 @ 03086b80] Increasing reorder buffer to 1
These lines occur frequently within the steady flow of the first line repeated. Because of “buffer” being mentioned as well as “novalidate”, I wonder if the problem is once again that my computer can’t handle the data flow. If that’s the case, then why was it able to export 12 videos prior, including one of 39 minutes, but can’t export this one of 24 minutes, or even 16 minutes after the video was truncated?
Has something changed within my computer since three weeks ago when I exported my previous video?
Can anyone offer an explanation or suggestions for a course of action? I still have many more videos I hope to produce and some have clips already recorded.
