Broken MPG Time

[Mathew Lankard]

I have a few MPGs of TV shows that I downloaded, and each one will only show up as a 8 or 11 minute file in WMP or BSPlayer. I can can jump to different points in the timeline and it will go to the end of the movie but will always stop when it hits the end of the 8 min or whatever. The sound will usually keep playing. I opened them up in VirtualDub and they show up as the full 45 minutes. Ive tried downloading them several times and the person Ive downlaoded from says he hasnt had any problems. I tried using the MPEG corrector but it only goes to the 8 min mark. Any ideas of how to correct these files? Any help would be greatly appreciated. Thanks!

Hi,

You can try WinDVD. That should play the whole file.

Can you scroll through or play the whole thing in Vdub ?

If so you could frameserve them to an encoder and re-encode

sounds like somebody used a binary joiner instead of something that understands mpeg structures (like TMPGenc)

if you can find a copy of it you could use M2 Edit Pro (I think it's called)
it was discontinued a while back but I recall that there were a few 30 day trial copies around - I also heard there was a open souce version on sourceforge.com - but I couldn't find it

I believe it could remove the frame packets and re-create a completed file with a new timestamp this should fix the playback problems

The only other thing you could try is mpeg repair - located in the tools section although I haven't tried it

Ok - I was wrong about the discontinued bit
http://www.mediaware.com.au/ProductInfo/M2editPRO/m2editpro.html
and it lists time-code repair as one of the features

trial version available too but at $1500 it's not cheap ouch!

Im trying to request a trial version of that software to see if it works. The problem with re-encoding is that my files are off tv and at a 312x240 resolution. In order to re-encode in TMPG I would have to add black bars on the side. I was thinking of doing this so I could trasfer to dvd but Im new to DVD and im not sure how many I will be able to fit on a disc. I believe the bit rate on the movies is 1150 and when I tried to use the wizard in TMPG it tells me that will take up half the disc. Plus im not to sure on the relation of the resolution from the file and how it would look on a DVD even with the low resolution standard.

Give up on M2-edit. The demo is about useless.

TMPGenc will resize to DVD compliant if you want.
You also can set the bitrate so it won't "take half the disk"

Get a bitrate calculator. Reencode to 320 x 240
You have to re-encode to something other than 312 x 240 anyway

I fixed the files with the trial version of that software. So let me prase my other question like this since Im new to MPEG2. How many 45 min MPEG1 1150kbs bit rate episodes should I try to fit on a 4.7G DVD?

[Jukka]

Assuming video bit rate is 1150 and audio bitrate is 224 (i.e. standard) then 45 mins works out at roughly 450-460mb, so in theory 8 - 10 episodes would be possible.
