Selur's Little Message Board

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."

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

Code:
"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"

in a Windows Command Prompt?
(can't test atm. myself since I'm in the middle of getting Hybrid to Qt6 compatible, which will take some time)

Wrong values: "fps=294" - right= 23.976
"-------------" "bitrate= 1.3kbits/s" - right=39.4 Mb/s
"-------------" video:18440662kB - right=1246927,468 kB

To me the values seem correct.

You are misinterpreting those values.

Quote:"fps=294" - right= 23.976

that is the processing speed not the video playback speed

Quote:"-------------" "bitrate= 1.3kbits/s" - right=39.4 Mb/s

that is the data rate at which the time codes are written, not the video speed

Quote:"-------------" video:18440662kB - right=1246927,468 kB

that is the raw video size not the file size,..

Based on the Mediainfo
Video:
Stream size : 1246927468
Stream size : 1.16 GiB (97%)
that is the raw video size?

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.
