unfa / kdenlive-multirender Goto Github PK

When i do this thing, I expected that thing, but instead it crashes.
I guess this is a bug, should I provide GDB output?

Sometimes melt rendering just crashes, leaving a useless video file behind.
In such a case the final concatenation will fail too. The user will have to manually re-run some kmr- scripts and then manually concatenate the whole thing again.

It'd be great to handle this withing the script.

The script seems to ignore the start frame.

The script seems to have unspecified dependencies, that are at unsatisfied at least on a typical Debian Testing installation.

For instance, this syntax would not work:

while [[ $(pgrep -f "bash kmr-" -c) > $(( $THREADS - 1 )) ]];

Replacing it with this worked.

while [ $(pgrep -f "bash kmr-" -c) -ge $THREADS ];

Same here, this didn’t work:

if [[ "breakpoints_mode"==TRUE ]]; then

But this worked:

if [ "breakpoints_mode" = TRUE ]; then

On the last line there is an invocation of:

"$(urldecode $PATHFILE/$TARGET)"

What is this urldecode? The command does not exist in my system, and apt-cache search urldecode finds nothing useful for it.

Hi unfa,

Thank you for creating this kdenlive multirender script.

I was wondering if you can explain the "16 4" after your script example? I only have an ancient dual-core computer with 4gb of system memory (ram) and I would like to use both cores / threads, so what would be the numbers after the script command? Whenever I tried this with any numbers after the script command it failed?

Regards,
Phil (phd21)

Hi, as you have worked in this field for a good amount of time I want to verify if in your scenario this technique can be applied?

If it works then we can give KDENlive community a suggestion to include a simple button for this. For me everything is working as expected. 2 hrs of rendering took 20 mints.
Let me know. Thanks.

The users don't really have to control this, it could be splitting the job into 5 or 10-minute parts.

For projects shorter than 5 minutes it could use smaller chunks to still make it faster.

After rendering the video, it is parted/fragmented in the number of threads it was rendered.

I suppose the end result should be 1 complete file.
Right?

[concat @ 0x5589597ea3c0] Impossible to open 'ST1-Story_Mode-Pt1-01.mp4'
list.txt: No such file or directory

The video files are saved to somewhere other than kdenlive-mulitirender.sh and the kdenlive script.

Not sure this is doable but I currently use Kdenlive on Windows and noticed that the script generator creates a .bat file for editing the code instead of the .sh script.

Test Project.bat:

set RENDERER="C:/Users/[USERNAME]/Desktop/Kdenlive-windows/kdenlive_render.exe"
set MELT="C:/Users/[USERNAME]/Desktop/Kdenlive-Windows/melt.exe"

set SOURCE_0="file:///D:/Projects/Test%Project/scripts/Test%Project.bat.mlt"
set TARGET_0="file:///D:/Projects/Test%Project/Test1.mp4"
set PARAMETERS_0="in=0 out=3168 %MELT% C:/Users/[USERNAME]/AppData/Roaming/kdenlive/profiles/customprofile5 avformat - %SOURCE_0% %TARGET_0% properties=x264-medium f=mp4 vcodec=libx264 acodec=aac g=120 crf=30 ab=128k preset=faster threads=4 real_time=-1"
%RENDERER% %PARAMETERS_0%

Is there a way to translate the .sh script to the .bat? would be awesome to have a multirender for windows. If not, well it doesn't hurt to ask. Thanks!

Melt outputs text files with progress information - this can be paserd and used to show nice progress information to the user.
