When using a non-integer atempo speed value (e.g.: 0.5, 1.0, 1.5, 2.0), the "Total progress" bar immediately fills to 100%, "Open on completions" folder, but file status remains at 0.0%.
You can see that the output file size increases to the expected size, but you can't opened it later.

Pass test with "Try preset / on console".

Works fine if you use int 2 instead of 2.0 for 200%.

No problems when converting manually with command line and 1.5 speed instead of program.

Parameters:

 -map 0:v:0 -map 0:a:0 -vf "setpts=PTS/1.5,fps=30,scale=w=640:h=360:force_original_aspect_ratio=decrease" -af "atempo=1.5" -c:v h264_nvenc -rc vbr_hq -qmin 0 -cq 34 -c:a aac -vbr 1

    Program doesn't send full and correct line prams, there is problem with some other filter values and -filter_complex syntax.

    adding single quotation marks ' ' around value may help in some cases.

    -af "atempo='1.5'"
    

    p.s. 3.2.2 still has that problem

    I've used these parameters in application and could not reproduce the issue, it worked fine

    -map 0:v:0 -map 0:a:0 -vf "setpts=PTS/1.5,fps=30,scale=w=640:h=360:force_original_aspect_ratio=decrease" -af "atempo=1.5" -c:v h264_nvenc -rc vbr_hq -qmin 0 -cq 34 -c:a aac -vbr 1
    

    Either with single quotation marks or without.
