.ts output filesize

[therat]

I was always of the opinion that .tp and .ts files were the same just put out by different programs. Evidentially this is not so or there is a problem with the .ts output in VRDP.

I'm using build 388 with a DVICO DVB-T Plus and FusionHDTV v3.0.2 software/drivers.

I recorded DV in .tp format and ended up with a 644mb file. After using VRDP to edit out the commercials (about 10% overall), I saved the file in .ts format.

The resulting .ts file was only 277mb only 3mb larger than the same DV saved in .vob format.

I thought the .ts output would be the same size as an equivalent .tp file eg ~580mb not half the size.

Is this correct?

cheers

Does the output file play properly ?

 

[therat]

yes it plays perfectly.

 

[litz]

yes it plays perfectly.

Check and see if maybe you were recording multiple streams in the .ts and VRD has simply extracted just the stream you wanted ...

Litz is correct. Open the original file and click on Tools>Select Stream. You should see multiple video streams.

PS. Litz, Saw some issues on the Discovery HD stuff. Pat's doing some investigation on it now to try and pinpoint the problem.

Cool, thx ... ain't it fun trying to get VRD to work with all these different TS streams, despite the fact that there's a "standard" ?

MPEG was not made to be editable, and TS streams even less so.

I did that and on the .tp file there are no less than 6 MPEG2 streams and on the .ts file there is only one.

Is that normal? I assumed that the .ts file would output the same as the .tp file.

If the .ts only outputs one MPEG2 steam, what is the point of having it as output to MPEG Program Stream would be the same wouldn't it? Or am I totally missing something?

Dan, Is there plans to support saving in multistream .tp format?

cheers

There are no plans to support more than one video stream per output file. There are plans to support multiple audio / subtitle streams. If we were to support multiple video streams then you would need to edit each one individually. Not sure what the benefit would be.

Yes, outputting to mpeg program stream is the same. There are some players and utilities that prefer TS output which is why we implemented the feature.

You can either pick the stream you want from the .tp file, or extract it wholesale using hdtvtompeg2, then edit it in VRD ...

Either way VRD's output is just a single stream (if you have six PIDs in your original, I assume it's probaby a SD signal? Or a single HD + a bunch of SD ?)

Note also that both Fusion and MyHD have options to have JUST the pids of your selected stream -- which saves TONS of disk space ...

Two QAM HDTV channels (if you're cable capping), for instance, is 38mb/s ... which is a good 20gb an hour. That can chew disk space frighteningly fast.

Just thought it might have been better quality. I'm probably wrong tho because the .ts and .tp files look the same quality on playback in my sample.

fair enough. that makes sense.

A bunch of SD I think.

Where is that option in Fusion please? I don't seem to be able to find it anywhere.

yes that's so true

I'm not sure where it is for Fusion (I don't use a fusion card anymore) but for MyHD it's buried in the capture setup details config window.

[therat]

The Fusion itself doesn't seem to have that option. The configuration is quite simple.

one good thing about the .ts output is that I can convert .tp files to .ts and NeroVision Express handles them perfectly whereas it won't handle the multi-channel .tp files.
