i am having several problems with rendering i tried to change the kdenlive language to en-US but i still have the same problems.

1 - having 2 video tracks, I place an image in V2 and having to add a slide composition at the beginning and end of the image, the preview works correctly but when rendering the video it ignores the composition (if it has a short duration like half a second for example) or makes it look much slower than in the preview from kdenlive (if not ignored).

2 - the rendered video appears to be smaller than a area between 2 guides i use for render (about 15 secs) leaving with 2 seconds less (13 secs) generating a difference between the rendered video and the preview do kdenlive in the time that the V2 image appears, stays and exits the screen.

3 - In the kdenlive preview the moment that V2 appears in relation to the audio is correct but after rendering it is delayed or in advance.

I'm using version 20.08 and windows 7 is my first time using kdenlive and I saw that the .kdenlive file is not backward compatible I would like to know if there is any solution that prevents me from having to re-edit everything again.

Change the system country setting to a point as decimal separator like EN or change your decimal separator in the setting to point. Win7/10: control panel -> Region & Language -> Formats -> additional settings -> Numbers -> decimal symbol: change from , (comma) to . (point). Then try to render.

Really Thanks

for some reason it really was with "," instead "."!
