Thanks Laine and Andrew . I do believe that yadif=1 is what I am looking for. After googling it I see so many others that express their love for it so that sounds right!

If you still have any of the transcoding output from before, it’s easy to verify that it wasn't telecine also by stepping through frame by frame. If you keep the 29.97 frame rate when transcoding telecine, you’ll normally get every 4th progressive frame duplicated. I say that because only a very small relative number of NTSC DVDs I’ve transcoded have been "not telecine". Transcoding telecine without pullup normally looks fine until you see a passage of slow, smooth horizontal panning. Then it’s like getting slapped in the face 6 times per second. But only you know what you have. You can specify your frame rate without pullup, I think, with something like "-r 59.94”. I’m sure you'd wan’t to adapt for your hardware for speed, but I’ve successfully upscaled progressive 29.97 FPS video with: ffmpeg -i input.ts -vf scale=-1:1440:flags=neighbor -r 59.94 -c:v libx264 -preset slow -crf 18 -b:v 2600k output.mp4 For my hardware (Mac Silicon), I dressed it up a little: ffmpeg -analyzeduration 100M -probesize 100M -loglevel error -stats -i input.ts -map 0:0 -filter:v scale=-1:1440:flags=neighbor -c:v h264_videotoolbox -b:v 2600k -color_primaries:v bt709 -color_trc:v bt709 -colorspace:v bt709 -metadata:s:v title= -disposition:v default -map 0:1 -c:a:0 copy -metadata:s:a:0 title= -disposition:a:0 default -sn -metadata:g title= -movflags disable_chpl output.mp4 L.

Re: [FFmpeg-user] Trying to remember how I did this.....
Its NOT Telecine. It is Digital Video 8 video at 27.97 FPS I am looking specifically for the setting that derives the 59.94FPS from the 27.97 FPS source with such beauty and without deinterlace.

There’s more than one way to apply pullup. What normally works best for me for NTSC DVD is to specify the output frame rate with "-r 24000/1001" and use some sort of fieldmatch video filter such as “fieldmatch" alone or "fieldmatch=order=tff:combmatch=none,decimate”. You may find that it isn’t necessary to specify the 24.976 frame rate. Use the filter before scaling or cropping in the filter chain. The source video needs to be pretty clean regarding pulldown (without or nearly without any dropped frames). You should be able to identify the pulldown pattern in your source by stepping through it frame by frame with a video player app such as IINA. By default it’s the “.” (period) key. If it’s telecine, you’ll be able to observe 3 progressive frames followed by 2 pairs of interlaced frames. Something to try, anyway. L.

[FFmpeg-user] Trying to remember how I did this.....
I had some DVD Video that I had converted using ffmpeg some years ago. What I did was converted NTSC DVD video (4x3) to 960x720 @59.94 FPS and the result was incredible. I had found a forum some time later where another user claimed he had done the same and he too had incredible results. The result as I recall is way better than deinterlacing and I still have some of the videos I upscaled this way. . It essentially creates a frame for every field and if I pause the video I may see a slight blur but no scan lines. I also see no scan lines while video is playing I do remember that I did it all with ffmpeg command line conversions. It does NOT use deinterlacing as that throws away half the resolution, and results in visible scan lines. Instead it increases the frame rate by two and I chose to upscale to 720P. As I recall I also did some PAL as well as NTSC using the same method. I am looking to recover this method if I can as I will be transferring a bunch of Digital8 videos and want to do it the same way to create mp4 files at 720P@59.94FPS Any help appreciated THanks Mark ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
