Hi, I need to reduce frame-rate from my video shoot by mobile ( variable frame-rate about 29 fps) to 25 fps. As you know using -r 25 just drops every 6th frame resulting in choppy (jerky) footage.
Is there any better option how to do it more smoothly (blending etc.)? Maintaining the same length of course:) Thanks Peter From: peter.che...@quick.cz To: ffmpeg-user@ffmpeg.org Subject: 90k tbn vs 30k tbn Date: Tue, 24 Feb 2015 16:46:15 +0000 Hello, I am down-scaling 4K video into 1080p, result is ok, but with different: - color info (bt709 vs Nothing) - tbn (90k vs 30k) - missing creation time (Metadata: creation_time : 2014-11-02 14:18:12 vs Empty) Input 4K video Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuvj420p(pc, bt709), 3840x2160 [SAR 1:1 DAR 16:9], 95173 kb/s, 29.97 fps, 29.97 tbr, 90k tbn, 59.9 Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 124 kb/s (default) Metadata: creation_time : 2014-11-02 14:18:12 Output 1080p Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuvj420p(pc), 1920x1080 [SAR 1:1 DAR 16:9], 21191 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc ( Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 124 kb/s (default) Metadata: creation_time : What should I add to have both the same?
