Due to lack of documentation, I thought I would leave this comment stating the switches of h264info.exe as of alpha 21 or later. Check the changelog at alpha 18 where he mentions command line. Running h264info.exe from command line with no switches will open the program normally.
The switches are CASE-sensitive! There CANNOT be a space between the switch and argument, if an argument is to be specified. If you specify any of the switches, you MUST specify the input and output files or it will fail. Quotes are allowed but not required (unless filename/path has spaces). Switches can be specified with the '-' or '/' or '\' or '?' character (seems like any symbol works) The default for all the switches, except input file and output file, is to get the information from the input file. Here are the valid switches that were found in the source code:
(the input file with path if needed)example: h264info.exe -imovie.264
(the output file with path)example: h264info.exe -omovie.new.264
(specify framerate) Must be 25, 29.97, 30, 50, 59.94, 60, or 23.976
(specify aspect ratio) Know options are 16:9,4:3, 1:1, 1, 2, 3, 4, 5, 14, or 15 Options 1-5, 14 and 15 are H264 Presets that are built in:
1 signifies 1:1 Square
2 signifies 4:3 PAL
3 signifies 4:3 NTSC
4 signifies 16:9 PAL
5 signifies 16:9 NTSC
14 signifies 16:9 without horizontal overscan 1440x1080
15 signifies 16:9 without horizontal overscan 1280x1080
(specify the H264 Level) Known options are 1.0, 1b, 1.1, 1.2, 1.3, 2, 2.1, 2.2, 3, 3.1, 3.2, 4, 4.1, 4.2, 5, or 5.1
(specify the width of the video) I believe the units are pixels
(specify the height of the video) I believe the units are pixels
(specify the maximum bitrate of the video) The units are kilobits per second
(specify the number of frames between reference frames)
For example "h264info.exe -n13" means display a full frame every 13 frames
Marvingj explained it well in his post:
-3 (enables 3:2 pulldown)
-r (disables 3:2 pulldown)
-2 (enables HD->BD Keep FPS) Quoted from the changelog, "HD to BR mode. It doesnt change the fps. just fixes gaps in frame num and a couple other params to make a hd stream work as a bluray stream. with this frame rate changes and thereby timing changes not needed. eliminates need for a 2-pass mode for accurate timing."
-p (enables Add Picture Structure)
-e (disables Write PPS every picture, default is enabled)
Hope this helps. I had a whole series of files that were 720x576p and the aspect ratio was stuck at 5/4 this is the only tool that would allow me to correct it using -a"4" switch. Thanks to command line I was able to start a batch file and walk away.
