Comment (by birdie):
Encoded video:
Duration: 00:20:54.19, start: 0.000000, bitrate: 3339 kb/s
Stream #0:0(eng): Video: h264 (High), yuv420p, 1920x1080 [SAR 1:1 DAR
16:9], 29.83 fps, 29.83 tbr, 1k tbn, 59.67 tbc (default)
Or: 27411 frames.
Source video:
Duration: 00:20:54.19, start: 0.000000, bitrate: 17098 kb/s
Stream #0:0(eng): Video: h264 (Baseline) (avc1 / 0x31637661), yuv420p,
1920x1080, 17000 kb/s, SAR 1:1 DAR 16:9, 29.85 fps, 29.83 tbr, 90ktbn,
180k tbc (default)
Or: 37429 frames
Actually just 18 frames have been lost during encoding but it's still not
very pleasant 'cause it's not clear why the frames were dismissed.
