Freezes during "extracting time codes - kingcrimsonster - 27.12.2020
Freezes during "extracting time codes using FFMPEG for track with id1"
File is the *.mov extension. Checked :Always extract timecodes from input" and "Only extract time codes for some containers:
mp4/mkv/flv input files will be extracted."
RE: Freezes during "extracting time codes - Selur - 27.12.2020
I know FFmpeg timecode extraction takes it's time and there is nothing I can do about it, but it shouldn't take that long.
What happen if you call
"C:\Program Files\Hybrid\64bit\ffmpeg.exe" -y -ignore_editlist true -i "H:\!_Video\Video_Mus\Lindsey Stirling\Beyond The Veil.mov" -map 0:1 -f mkvtimestamp_v2 "C:\Windows\Temp\Beyond The Veil.txt"(can't test atm. myself since I'm in the middle of getting Hybrid to Qt6 compatible, which will take some time)

To me the values seem correct.
You are misinterpreting those values.
Quote:"fps=294" - right= 23.976that is the processing speed not the video playback speed

Based on the Mediainfo
Video:
Stream size : 1246927468
Stream size : 1.16 GiB (97%)
that is the raw video size?
RE: Freezes during "extracting time codes - Selur - 27.12.2020
Quote:that is the raw video size?iirc. FFmpeg shows the raw 'uncompressed' video size it processed during the processing, MediaInfo reports a guessed 'compressed' stream size.
-> if you want to know in details check the ffmpeg source code (iirc. ffmpeg.c is the file where it's output).
(or in whatever documentation they hid it,..)

I'll add a progress indication to the ffmpeg time code extraction this way it shouldn't look like the gui is frozen.
