please reply ASAP

[NathanLovato]

You shouldn't include the -j option when doing a full render with bpsrender. You can run your command as bpsrender -w3 D:\YOUTUBE\Blender\ESclass.blend instead. The join operation is included. The -j option is only to [re-]join previously rendered chunks.

Could you try this and tell me if it works?

Also, if not, could you tell me exactly what happens? Print the content of the bpsrender directory next to your video, and tell me what doesn't work and what is the expected output (e.g. if you don't get any video in the end)?

This the result without using -j cmd

[ME-TECH-ELECTRONICS]

These are the blender settings

[ME-TECH-ELECTRONICS]

The video and audio renders in mp4 and flac file but cannot join them to make the final file. I noticed that file is 0 Bytes (final file size )

[NathanLovato]

Could you run the command python -m bpsrender --dry-run -w 3 D:\YOUTUBE\Blender\test.blend ?

This will output the commands bpsrender would run without actually calling them (dry run). It will output the ffmpeg command that joins the file. You can copy that command and paste it in your terminal to see why ffmpeg is failing. I'll need this output to help you.

This is the output of dry run

[NathanLovato]

I think the issue is just you didn't set the export path in blender. You most likely need the output to end with something like file_name.mp4.

[ME-TECH-ELECTRONICS]

Can you just explain how to do this

[NathanLovato]

Sure. Here, see the Output section at the bottom left of your image? The output path is currently /tmp. If you replace it with a name like test.mp4 and save your blend file, it may solve your problem.

You can write the path like this in Blender to save relative to your .blend file's location: //test.mp4 (with two leading slashes).

it is still showing the same error

[NathanLovato]

you have to use the dry run option again and manually run the join command from ffmpeg. It seems like there's an issue either with your ffmpeg or with file paths.

[me-tech3152]

Can you just highlight the join cammand from above dry run result to run the join operation
