[FFmpeg-user] cat advice

Hello, Prior to joining files with cat I often convert them using ffmpeg -i inputFile -target ntsc-dvd -qscale 5 outputFile to make them similar quality before joining. The problem with doing this is often the aspect ratio even if I use the -aspect flag. Does anyone have a suggestion on how to

Re: [FFmpeg-user] -movflags faststart revisited

Thanx. Are there any flags that will let me playback an unfinished transcode? Reason I am asking is that if my various options in the transcode command did not yield what I like, then I would like to abort the transcode. Kind regards, JD On Sat, Feb 25, 2017 at 9:28 PM, Geek.Song

Re: [FFmpeg-user] -pix_fmt yuv420p and deinterlacing

Thanks again, Andy. So if I understand correctly: 1. *-vf scale=interl=1* registers to libx264 that the input is interlaced and to be 'aware' of that in future operations. *yadif*, of course, does the actual deinterlacing. 2. If used in the same script, *scale* must precede *yadif.
