Hello, sorry for the long post.
I can’t export a project made of various clips of various format and fps. During the editing and while importing videos, I exported the project to see the work in progress before adding the rest of clips and all worked very well! After importing the last clip, I tried to export the last WIP before adding the final credits (it will be another clip made in Blender that still doesn’t exist) and the soundtrack, the exporting job stops at 24% for long time, untill I manually end it. During this long wait at 24%, neither Shotcut nor PC are blocked, there’s only a RAM usage of about 80-90%. I read the events log and I noticed that the render procedure blocks at 24% on a particular clip. I tried to replace the clip with another cutted at the same timecode, but the problem was not solved, rather it appears at 23% on the previous clip. So I tried to replace the previous clip and the block appears at 24% again. I replaced the next clip and it blocks at 25%…
In the taskmanager I noticed that the qmelt.exe process is hungry of memory and while the Shotcut process continues to use the same memory, the qmelt one has ups and downs, but no process is blocked. On the Shotcut Google+ page I found a post where a user with a similar problem tried to open Shotcut with Administrator privileges and it worked well. I tried the same, but nothing changed.
The exported part video is unplayable and its size is about 157-160 Mb, while the last WIP exported video was about 800 Mb. The final video will be surely over 1 Gb for about 25’, credits included.
Shotcut 18.01.02, Win7 32bit, Intel Core2 Duo, 2 GB RAM.
Finally, how I can resolve this problem? Is the 1 Gb video file size a limit for my prehistoric system and Shotcut has been cornered? TIA to those who have had the patience to read up to here.
