MPEG Joiner ?

[ashe09]

i have 5 parts of MPEG files from Different videos (video size is different)
now i want to join that part and make a one big MPEG file any suggestions ?

As the sizes are different must you reconvert. Add all mpgs in freemake video converter, choose join files at top right, convert to mpeg.

copy /b file1.mpg + file2.mpg + file3.mpg + file4.mpg + file5.mpg filebig.mpg

simplest way and it should work quite well but if You want perfect then demux ES, change timestamps in each ES in way that there is full continuity, add binary as in my example, similar in audio, then create Program Stream

It wont work if the video size/resolution is different.

i can't get you,in which software man ?

It's from the command prompt(Run->cmd). BUT it wont work if the video size/resolution is different! All properties must be same then.

Nope, it will work very fine even for mixed (SD/HD) content. To be honest every GOP can have different resolution and properties.

Well, maybe in some players like VLC but not all.

thanks for pandy to quick reply
and mega thanks to Baldrick,
my problem is solve i use the free make video converter(for size issue) & then use fast avi mpeg joiner 1.1.2

Well - it just mean that player is poor - MPEG closed GOP is all You need to decode sequence - lot of broadcasters can change resolution and parameters (for example signaled aspect ratio, quantization matrices etc.) dynamically in real time and decoder must follow those changes immediately (usually nearest VBLANK). You can have some issues when open GOP is used (B frames can be lost at beginning).

firstly try my method - it is fast (pure copy on HDD) and without recoding ie loosing quality - if it fails go for method described by Baldrick. GL

I just did a test. IT worked fine in VLC. But not in mpc,mpchc, wmp. Didn't know this. Thanks for info pandy!

so from technical point of view - demuxing ES, modify GOP timestamps and no open GOP's (some B frames can be lost at the beginning), then binary add and remux - this should work ALWAYS (it is valid from MPEG point of view).
