Hello,

I am new user of kdenlive. I am putting together a video of me playing handbells. The song consists of two sections. Each section will have six video/audio tracks. There will also be two audio only click tracks.

This has been my work flow:

1 Insert first click track
2 Insert first AV track
3 Line up the AV track to the click track as required
4 Insert second AV track
5 Line up that track with the click track
6 Verify that both A/V tracks line up as expected by previewing (audio only), make minor adjustments as needed
7 Repeat steps 4 through 6 until the first six A/V tracks are lined up
8 Do some video editing so that all six videos appear at once (excited that this is easily accomplished!)
9 Insert second click track (this one has a different tempo)
10 Repeat steps 4 through 6 until the second set of A/V tracks are placed appropriately

When working with the second set of tracks I noticed several items:

1 The wave forms for the audio do not appear to be at the same scale as when there only 4 audio clips
2 When previewing the project (the only tracks "active" were the "new" audio track and the click track) the playback is not smooth
3 By the time I reached the last A/V track the preview was so jumpy that previewing was not an option

My question/s:

1 Is the performance of kdenlive dependent on the number of tracks in the project, not the number tracks that are "visible/audible" in the preview?
2 Is my laptop the issue? Below are the specs of my machine. I would truly appreciate any suggestions/tricks/hints that would help to successfully complete my project. Thanks much for everything!

Have a great day and stay safe!

Don

It's a quite common and understandable problem - any soft will suffer through performance issues is you're trying to work on 15+ projects at once.

and the CPU used is very poor...

and what kind of disk is this? (a standard one 5400?)


P.S. this is how the speed-interface looks on my test-pc : https://www.youtube.com/watch?v=vJvuVpHQFr8

Thanks so much for the quick response. I will have to keep on keepin on...
