Description S. Christian Collins 2016-10-18 07:22:55 UTC
If I proxy a clip and then render the project, the proxy ends up being used for the final render, dispete "render using proxy clips" being unchecked in the render options (under "More options"). I have to un-proxy the clip for the source clip to actually be used in the final render.

The 16.08.2 release notes mentioned this bug as being fixed (I'm guessing it was a reference to bug #368491?)

Reproducible: Always

Steps to Reproduce:
1. Drag a video into Kdenlive's project bin. (Here is the video file I was using to repro this bug: https://dl.dropboxusercontent.com/u/8126161/audio-video-sync-test.avi)
2. Turn the clip into a proxy and put it on the timeline.
3. Render the project and make sure "render using proxy clips" is de-selected under "More options". I used the default WebM profile for this.

Actual Results:  
The rendered video file is very blurry and the audio is lo-fi from using the proxy clip.

Now, de-proxy the clip and render again.
Result: high quality video and audio.

Expected Results:  
Proxy clips should not be used for the final render unless "render using proxy clips" is selected.

Kdenlive 16.08.2 w/ MLT 6.0.0
OS: KDE Neon 5.8.1 64-bit (Plasma Desktop 5.8.1, KDE Frameworks 5.27.0, Qt 5.7.0)

Can confirm this. The proxy feature is very cool but when the result is rendered with the proxy file, its nit useless.

Hi there...

This looks like this bug is only triggered for me on new, unsaved projects. 

Once I have saved the project, and hit "revert to last saved" kdenlive respects the setting "render using proxy clips" being un-ticked. 

I hope this helps in tracking it down. 

At least it is a not so painful workaround.

I cannot reproduce this problem. Could you attach a simple project file that triggers the bug for you ?

Oh, wait. I just managed to reproduce for the first time, great!! working on it.
