Why MEDIAINFO don't report if video is NTSC or PAL?

[marcorocchini]

Hi ****

I have some videos of my cats in PAL and others in NTSC (all from my gopro camera) but MediaInfo don't tell nothing about ntsc or pal, how can I have this info in the report of mediainfo? thanks

[newpball]

There is a tag called STANDARD in media info which is used to show if a file is NTSC or PAL. If it is not there it is not Mediainfo's fault.

[marcorocchini]

thanks, so from command line what I have to type? (to get the pal/ntsc info in a .txt file)

I know , for example, mediainfo generate his report in a txt file with

medianfo.exe input.mp4 dumpinfo:unicodefile.txt

How I tell to mediainfo the use of "standard" tag?

Just look at the frame rate. If it's 25 or 50 it's "PAL." (PAL is SD only, so there is less and less true PAL or NTSC being generated anymore.)

gopro can shoot, for example @ 48 fps both in NTSC or PAL mode ("PAL" also if it shoot only in HD)

100 fps of gopro in common to the ntsc and pal mode

I need, if possibile, to distinguish between this modes with a "ufficial" information, even if is passed to the mediainfo

NTSC and PAL are analog video standards. Digital video files may or may not have anything in common with those standards.

yes I know PAL and NTSC are not HD, however also the gopro menu (in a conventional manner) have the setting "PAL or NTSC"

I sould batch automate:

IF the input video is ""PAL"" use

AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave().Trim(0, last.FrameCount/2-1)

but if the video input is ""NTSC"" use

AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave().Trim(0, last.FrameCount/2-2)

        rem ***Make The .avs Script File***
        echo Import^("C:\Program Files\AviSynth\plugins\IcResize.avsi"^)>%2
        echo FFVideoSource^(%4^)>>%2
        echo ConvertToYUY2^(interlaced=false^)>>%2
        rem echo ColorYUV^(levels="PC->TV"^)>>%2
        rem echo ColorYUV^(gamma_y=-7, gamma_u=-7, gamma_v=-7^)>>%2
        echo LanczosResize^(720,576^)>>%2

        IF "%gopro50fps%"=="1" echo AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave().Trim^(0, last.FrameCount/2-1^)>>%2
        IF "%gopro50fps%"=="1" echo AssumeFPS^(25^)>>%2

        IF NOT "%GOproFPS25OR50%"=="1" echo SmoothFPS2^(50000,1000^)>>%2
        IF NOT "%GOproFPS25OR50%"=="1" if "%gopro48fps%"=="1" echo AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave().Trim^(0, last.FrameCount/2-1^)>>%2
        IF NOT "%GOproFPS25OR50%"=="1" if "%gopro100fps%"=="1" echo AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave().Trim^(0, last.FrameCount/2-2^)>>%2
        IF NOT "%GOproFPS25OR50%"=="1" if not "%gopro48or100fps%"=="1" echo AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave().Trim^(0, last.FrameCount/2-2^)>>%2
        IF NOT "%GOproFPS25OR50%"=="1" echo AssumeFPS^(25^)>>%2

       echo processing source file %4

for this I try to get the "pal" on "NTSC" info by the mediainfo

but if the video input is ""NTSC"" use

AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave().Trim(0, last.FrameCount/2-2)

The first line works to remove the orphaned field at the end of any source video with an odd number of frames. NTSC vs. PAL properties makes no difference.

Out of curiosity what is the point in weaving the frames? On what player or format is your video rendered?

He's converting 50p to 25i. Or 60p to 30i. Etc. He insists on ruining his videos because he uses an ancient editor with many limitations.
