Hello Friends!

New kdenlive user here. I have a 9.4mb video that has audio. I muted it and shortened the video.

I expected the video to be less than 9.4mb after rendering.

Instead the result was a 29mb video.

Shortened video and no sound, yet file size became bigger.

Why is that?

Thank you for your time!

Hi there.
First, the size of a video file has more parameters. Some codecs are compressed, others not, and bitrate plays a role.
Look carefully at the render dialog, pay attention to the quality parameters - they set the bitrate I believe. Click the "more options" checkbox to see details.
If you want to get rid of audio, ungroup the video and audio and delete the track entirely, or undchek the "export audio" option in the export details.
To see the details of your original and exported video, use mediainfo, that may help understanding the problem.

yep.. this is usual from 20+ years ago... (from divx/xvid era) some files (maybe) become out from an user that spent hours to try an try to reduce size without lossing (too much) quality... and is virtually impossible to reproduce the same audio/video ratio with smaller size and without quality loss...
on latest 5 years the social medias and computers and storages can handle very very big files and usually to be sure to no have a quality loss no one care about this "effect"...
i'm also rendering smartphone MP4 with output rendered 10 times larger than original clips... but i want to be sure that added "titles" and "effects" can have best the best quality possible (no edges... no squares... smooth and clean...)
btw i suggest you to identify the original files codecs (audio/video) and resolution/framerate using some tools... (i'm on Windows and for example i'm using "Mediainfo"..available for every platform on the planet ) just to be sure to replicate the exact codecs used on the original clip...

P.S. if you want to be sure to remove the audio trace "de-flag" EXPORT AUDIO on rendering dialog.
