MP4 trimmer?

Pigman II

Hi all,

I recently bought the Pinnacle Video transfer that can encode any video input signal to MP4. For the most part when I'm using this device I just leave the thing recording overnight and in the morning I have the programme I want to see. PVT works by continually increasing the file size of the recording until the file hits 4gigs and then it just continutes recording with a second file until that reaches 4gigs and so on.

The problem is that now I have a lot of 4 gig files that can be as much 90% wasted space because I may for example only have wanted 30mins out of the 7hour (4 gig) recording.

I need a program that can trim off the "fat", the before and after and leave me with just a 30min (500meg) file.

I found a programme that was ideal by a company called Allok but the only problem is that it can't handle 4gig files.

So basically what I'm looking for is a user friendly program that trim Mp4 files that are as large as 4gig in size.

All recommendations gratefully recieved.

Does Windows Movie Maker do that? I'm on linux atm so can't check, but i thought you can do stuff like that easily enough...

Dvdshrink use to do this type of thing. Not sure what formats are supported anymore ,I haven't used it in years.

dvdshrink32.exe is the filename.

Heres a link http://www.afterdawn.com/software/video_software/dvd_rippers/dvd_shrink.cfm

Thing is does it (as the name suggests) just shrink a big file down to a smaller?

HDD storage or file Size is not a particular problem for me. I just don't want a seven hour file where only 30mins is relevant irrespective of the filesize.

Its for cutting up the file without altrering the bitrate. It's been so long since I used it though ,not sure of the ins and outs of it.

Cool. Thanks. I'll give it a shot.

Tried dvdshrink. It appears to be purely for compressing DVD data and will not accept mp4 files.

Any other suggestions?

Sorry bout that ,thought it was for mpeg files.
Maybe try the HTPC forum or the portable media player forum.
Sometimes lads use convertors and video tools for mobiles/media players.

Yeah, dvdshrink isn't intended for anything like that.

I haven't used it but I've seen Blender recommended for this very thing (using the video sequence editor part of the app).
