Using melt standalone because of too less DRAM

Help/How To
1

Hello,
I did create an mlt script for a 12 hour long silent 4k video. It just shows 333 flowers in a slide show an repeats after 2h21.
Because I do only have 32GB RAM I cannot run melt inside of Shotcut!
According to your forum I did try to export the video with this command:
melt BlumenWZ1_1148.mlt real_time=“-4” an=“1” target=“/home/alex/Videos/Blumen3/BlumenWZ1_12h.mp4” bf=“0” vcodec=“hevc_nvenc” rc=“constqp” aspect=“1.77778” f=“mp4” g=“125” width=“3840” vq=“15” top_field_first=“2” height=“2160” mlt_service=“avformat” deinterlacer=“bwdif” rescale=“bilinear” threads=“5” audio_off=“1” movflags=“+faststart” vglobal_quality=“15”

melt processed all my >1 million frames over the night but no output file was generated!
Please tell me what I did wrong!
Thanks!

Your reference entry how I did compose the melt call:

That is not what the post tells you to do. Your command should be:

melt /path/to/xml from step 3

You should follow the 6 steps in the post you linked. The only change is that the name is “melt”, not “qmelt”.

Thanks for your fast answer. I will try this tomorrow!

I also suggest to practice it with a small project. :slight_smile: In addition, using Parallel processing (real_time property) uses more memory.

Sadly I did use melt because I do not have qmelt on my PC and I do not know how to get this command.
I did not find qmelt in the appimage container.
Under Shotcut everything works fine except of the memory issue with large images!
In the terminal not:
melt delivers the videos only in the correct aspect if I remove all size and aspect settings.
Surprisingly some of the jpg photos which are all generated with darktable are not displayed at all.
Because darktable does have an issue with correct pixel size output I also corrected the pixelsize with gThumb with the same results. melt finds all jpgs but it does not like all jpgs.

This is still wrong. The command should only be:

melt path-to-file-that-you-saved-when-you-right-clicked-on-the-export-job.mlt

There should literally be no other parameters in the command.
Also, make sure you are using the version of melt that was provided with your Shotcut version. Do not use a different version of melt that might be installed on your system.

Can you please provide:

  • The exact command you are executing (including the path to melt)?
  • The MLT/XML file that you are passing to melt?
  • A screenshot of the “About” screen from Shotcut?
  • The output of “melt -version”?

Thank you brain for this new input. It is more simple to do this in this way and I think this is also the call out of Shotcut generating the images.
Maybe there is an issue with the text encoding with the mlt file on my pc. My native language is german and linux normally uses latin1 or utf8 for text files. But there is no change in the mlt file when changing from utf8 to latin1 or to ASCII with notepadqq.

I did install Shotcut normally on my pc via the manjaro installation system to use melt!

I also did make an trace to track the error and here I did find something:
Strangely melt could not open all source files on my second SATA hard disc:
