how to upscale and encode ass subtitle at the same time？

[i990049]

The original file is 1920*804,  and I want to upscale to 1920*1080 like this picture, and encode  the ass subtitle out of movie screen at the same time. Please tell me how to do it, thanks.

Add borders by:

• enabling "Crop/Resize->Base->Letterbox" and setting Width&Height to 1920x1080
  

and encode the ass subtitle out of movie screen at the same time

Assuming you want to embed / hard-code the subtitle:

• enable "Base->Subtitle"
  
• select the subtitle file under "Subtitle->Import->Subtitle Import->Load external subtitle"
  
• enable "Subtitle->Import->Subtitle Import->Embed subtitle in frame"
  
• press "Subtitle->Subtitle Queue->add current subtitle ..."

I tried several times,upscale is ok.But embed subtitle at the same time failed.I use x
264 crf mode.Do i have to encode again just for embeding subtitle？Is it possible upscaling and embed subtitle at the same time？

Without a debug output I can't tell what you are doing wrong.
Yes, scaling and embedding can be done at the same time.
If you do, you might want to check the 'Vapoursynth Preview' assuming you use Vapoursynth, to be sure the Subtitles have the correct height, etc. .
Depending on the scaling of your subtitles you might want to move the 'AddingSubtitle'- before (or after; which is the default) the 'Resize'-filter under 'Filtering->Vapoursynth->Misc->Filter Order/Queue'.
