as already said here http://forum.doom9.org/showthread.php?t=124347
Ive have a problem with a 20gb skyHD h.264 .ts file, when trying to extract & remux the video to .mkv I got a glitch in it. but it seems the glitch happened at the muxing as the extracted raw .h264 file doesnt have it. so I wanted to try to mux the raw .h264 to mp4 first and then into .mkv, but the filesize is too big for mp4box. I tried to use mp4creator then, but the commands didnt work for me and I guess I didnt undestand the command line help.

could anyone help me out, what commands I have to use in that case ?
Thanks,

Thunderbolt

Try to use the (g)dsmux from the Haali Media Filters package instead and choose mp4 as output format. This tool is able to load .ts files.

gdsmux is only the gui for dsmux, right ?
I opened the .ts file there, but it gave me a solution of 1920x1080, even though its 1920x1088 (mpc shows me this, if I would only make it 1080 or choose as DAR 16:9 and not 1920x1088 then the visible vertical picture would be like 1,5 mm smaller at top and bottom).
am I seeing it right that I cant choose mp4 as output file in the gui ?

muxed the mp4 file in .mkv, but its still unaccessable with mpc/ffdshow. worked with vlc, but even though I entered 1920x1088 as resolution @mkvmerge, vlc shows me 1920x1080.

About MPC/FFdshow, what kind of matroska splitter do you use ? The Haali's one or the MPC's one ?

edit: just tried to mux directly a .ts file (1920x1088) into a .mkv file within this tool and resolution is correct with the Haali Media Splitter through MPC...

tried the same now with dsmux command line, even entering ...;0.ar=1920x1088 but still got 1920x1080 in the muxed file, according to media info.

maybe dsmux has problems with skyHD files, dunno

I usually use the mpc splitter, but tried it now with the hali one. at properties it gave me for the line video size 1920x1088, but in the box below it said Video: MPEG4 Video (H264) 1920x1080 (30:17) [Video]. dunno what hes actually displaying now, if the actually displayed video has exactly the same size as the original .ts has. but at least 30:17 exactly corresponds to 1920x1088.
so what does he show now, 1088 as actual size or 1080, but with the ar of 1.76 as if it were 1088 ?

tried it again now, with mpc it neither works correctly with internal or haali splitter, the mkv just closed directly after opening.
it works with vlc though, but the ar is x1080 and not x1088 here. I guess the source is quite hard to handle.

so could anyone tell me plz how I do use mp4creator corretly here ?
