I am working on a MLT bug report: "melt eats more memory than available"<br>

It is still not yet clear if this large and complex project simply requires much memory, or if there is a leak. However, my suggestion to alleviate the problem can be considered successful: add "autoclose=1" to each MLT playlist when making the render XML. I have known about this for some time, suggested it in the past to users, and recently I added it to Shotcut. It is documented here [1]. The memory saving is not always dramatic as this particular case, but at least it will save many people from having a problem while rendering from the GUI - both of which can be memory hungry. Also, it might be a good, easy improvement to add to Kdenlive.<br>

Thanks Dan, <br>
I applied this fix. <br>
By the way, that might not be related but in Kdenlive we use a playlist to hold our project clips, like you do in Shotcut with the "main bin" playlist and there also seems to be memory issues with clip management.<br>
<br>
Open Kdenlive, empty project. Memory usage: 92Mb<br>
Add a 19Gb clip to Bin. Memory usage: 520Mb<br>
Remove clip from Bin. Memory usage: 502Mb<br>
<br>
Memory is not freed after deleting a clip from bin.<br>
<br>
Same thing happens in Shotcut. When adding a clip to the playlist and deleting it, memory is not recovered.<br>
<br>
I noticed this several months ago and I think with older Kdenlive/MLT versions, memory was freed when deleting a clip... in case it can help with your investigations...<br>
<br>
regards<br>
