I am having a minor issue when using FFMPEG to do frame accurate clip &
re-wrapping of a ProRes 422 (LT) source. I created a ProRes 422 (LT) 1080p
23.98 MOV with timecode burn-in & different sections that have green or
purple. My goal was to test FFMPEG to clip & re-wrap these sections to new
files and confirm the clip was accurate to what I was trying to pull. With
a 1080p23.98 source file, the second clip I made from the source showed
the incorrect in-point. I calculated the in-point (-ss) & duration (-t)
based on a duration of each frame at 23.976 being 41.708 milliseconds. For
the two clips I made, the clip that was an even 15 seconds had no issues,
but the second clip I made, had some odd behavior which was different
based on the QuickTime application used.
In Adobe Premiere CC 2014, the purple clip has no issues and displays
normally from 01:00:00:00 to 01:00:14:23. The green clip has an issue and
shows the starting frame as 01:00:36:16 instead of 01:00:36:17, the
timecode start was set to 01:00:36:17 which causes the clip to be off by
one frame. At the end of the file the frame 01:01:46:15 dos[;aus twice.
With Avid Media Composer 8.2, the purple clip has no issues and works
normally. The green clip when loaded into Media Composer starts on the
correct frame 01:00:36:17, but after 01:01:46:16 it displays the frame
01:01:46:15 twice.
QuickTime Player X displays the purple clip without issue. The green clip
starts a frame early the same as with Adobe Premiere. Unlike Premiere
QuickTime X displays the last frame 01:01:46:16 correctly.
QuickTime Player 7 displays the purple clip without issue. The green clip
starts a frame early and the timecode reader window in QuickTime 7 does
not advance when going from frame 0 to 1. QuickTime player 7 displays the
last frame of video (01:01:46:16) times. For two of these frames the
timecode value stays at 01:01:46:16, but the last frame displays
01:01:46:17.
Comparing the purple clip to the green clip based on the ffprobe output, I
can see that the green clip has negative values set for start_pts &
start_time for the audio and video tracks, except for the timecode track.
Purple segment start timecode 01:00:00:00:
In point for frame 360 is 15014.88 milliseconds: 00:00:15.015
Out point for frame 720 is 30029.76 millisecods: 00:00:30.029
Duration of clip is 15014.88 milliseconds: 00:00:15.015
