Wow - I barely remember writing some of those posts from...2004!

I havent tried PS3 playback at all but three suggestions:

1) Will the PS3 play an HD program stream (usually they are .mpg whereas .m2t signifies transport stream)? If so, its fast to remux from one to the other (see below).

2) Since 2004 a very handy utility called mpegstreamclip has been developed. My guess is it will either split your original files, or else fix the faulty files you've split already. Or both. It can also do remuxing to and from ts and ps http://www.squared5.com/

3) This might be worth a try too: http://www.videohelp.com/tools/MPEG2Repair

Just a note about Vegas 8. It apparently will allow you to split now, and it won't reencode otherwise untouched material. Seems to me you could take your 10 gig file and split it on the time line at a opportune point, and then go to render and it should copy the split. It actually has a message come up that says something like its not reencoding.

Thanks for these 2 very helpful replies. I'll try mpegstreamclip which I'd actually already downloaded but didn't think to check. I have Vegas 6d but haven't upgraded to vegas 8 as I don't really need the extra faciliities. Worth remembering though if needed.

Thanks again and I'll report back.

How about TSSplitter v1.0 ?

It works for, I split into 4GB chunks and put them on a USB drive (FAT32) and play from my PS3. Never tried to put them back to tape though the blurb does say "The advantage compared to other similar tools is that you can later join the files and get a file that's 100% like the original source file".

Mpeg Streamclip works! I was a bit thrown by the fact that I had to save the files as .ts files but once saved, I just re-name them as .m2t files and copy them to DVD-R (DL) and they play perfectly in the PS3.

The only thing I've noticed is that the extracted clips are a bit lighter (increased brightness) when compared side by side to the original. I don't know why this should be and if viewed in isolation its not really an issue.

Still, a real result. Thanks guys.

Thanks Claire for your help too. I might give that program a go too. The only thing is I want to create files bigger than 4Gb that I can copy to dual layer disks. Does it do that?

Thanks

I believe so David, it's a while since I used it because now I have bought a Pioneer BDR202 burner and so no longer need to cling to m2t's to put on USB drives for PS3 but I recall it would even let me preview the beginning and end of the the pieces it was going to make to avoid cutting between mid sentence.

Let me say I'm not wanting a scene detection utility or anything like that, I just want something to split it so the files could then be placed back to back on the timeline and fit together just like they had been as one large file (i.e. no skips, drop outs, etc.).

Thanks,

There's an excellent freeware file splitter called, "HJ Split", which I used as recently as yesterday as it happens (splitting a 12GB .m2t file into DVD-friendly chunks), which I recommend you try.

Unlike prog's which split a large M2T into smaller M2T files (invariably interfering with the integrity of the mpeg stream to one degree or other), "HJ Split" merely splits a file into smaller chunks of data, the size of which can be set by the user; all resultant parts will be of equal size with the exception of the final part which will be whatever the remainder of the file is (e.g a 12.6GB file split into 4GB chunks will result in 3 x 4GB files + 1 x .6GB file). The files can then be burned to disc.

If you ever need to reconstitute the file, copy the split files from disc to your hard drive and rejoin them as the original single file using HJ Split.

From experience, cutting a single M2T file into smaller M2T files can be problematic. Even though virtually all MPEG editors/splitters claim that they do not alter the stream in any way, they actually do and this can cause headaches later down the track (Avid Xpress users take special note). HJ Split will circumvent any such problem.

One word of advice, do a test: split the file using HJ split, burn the files to your DVD's or CD's, copy the files back to your hard drive, rejoin with HJ Split, play the joined file.

cheers.

"Split4DVD_ß.exe" is best. It splits every large file into portions of 4.4 GB (that you can adjust), and then you can burn it on dvd. You have to rename it from mpeg to mpg first. It is freeware.

cheers

Splitting m2t File
 
Ok, several years later and still a helpful solution.
Thanks David! I'm posting this to the Avid community.

These days you might as well archive to an external drive for roughly the same storage cost as burning to DVDs. Saves having to mess around with splitting files down.

Hi,

Mpg2cut2 (Mpeg2cut2) splits MT2 files on GOP. I use it for taking dross out of my HV30 files prior to archiving the result. I edit the cut files in PP4 with no problem. It only cuts on GOP and I only use the simplest of commands (set start - set end - write out the trimmed file) so I can't vouch for the ability to join two trimmed parts and things like that. But it really has helped me with a quick way of extracting the data I want without the necessity to re-render due to the file being split between GOPs.

Not sure this will fit your bill, but it may be worth a look for you. Best of all, it's freeware!

Cheers, Ian
