QSVEnc question - Nero - 21.02.2023
Hi.
Is there any way to disable "--y4m" from being automatically added to the command line in order to use another reader/decoder supported by QSVEnc?

Thanks for reading.
RE: QSVEnc question - Selur - 21.02.2023
No, Hybrid uses:
--y4m when Vapoursynth or Avisynth input is used.
--avhw when 'QSVEnc->Hardware->Only use encoder' is enabled

Got it.
So, could you please add "--vpp-subburn" to the "QSVEnc->Hardware" tab, so it can be used with "--avhw"?
I know that it is possible to do this manually under "QSVEnc->Misc->Custom command line addition", but it's a pain to do this individually with many files.

Thanks anyway for answering my previous question. ^^

Quote:So, could you please add "--vpp-subburn" to the "QSVEnc->Hardware" tab, so it can be used with "--avhw"?Since it seems like you have used the option before, I got a few questions:
- What subtitle formats are supported? (I suspect ass, srt and pgs, but what about ttxt, WebVTT, idx/sub?)
- Can filename be used together with 'track' to get the subtitle from another container file?
- shaping is only for text (not image) based subtitles, correct?
- scale is only used for image based subtitles, correct?
- transparency <- does this work with image and text based subtitles?
- brightness <- does this work with image and text based subtitles?
- contrast <- does this work with image and text based subtitles?
- vid_ts_offset <- does this work with image and text based subtitles?
- ts_offset <- does this work with image and text based subtitles?
- forced_subs_only <- this does only work when 'track' is used, correct? (otherwise I don't see where the 'forced'-info should come from)
- charcode <- what are all the possible options for this?
All these need to be known before adding this to Hybrid makes any sense to me.
(Yes, personally, I'm no fan of hardcoded/burned-in subtitles, which is probably the main reason why I never cared about the option.)
=> if you can't answer these, this will probably not happen any time soon, since I probably can't motivate myself to spend my weekends testing this.

But take your time, considering an addition for the future is good enough.
