Vegas 7 playbackspeed of mpeg2

[Josh Meredith]

I don’t have a solution, but I think the improvement in Vegas 7 is for “m2t” files, not “mpeg2” files.

M2t’s are HDV files. Vegas 7 handles these very well.

Mpeg2 is a file for making a DVD . I’m not sure Vegas 7 claims any improvement in playback of these files, but I could be mistaken.

That said, I’m surprised the mpeg2 files are playing back poorly. I rarely import an mpeg2 into the Vegas timeline, but I just tried it in V7, and it worked fine.

m2t is a transportstream for an mpeg2 file.
My V7 plays back m2t in a HDV project very very bad as well (about 3 fps with around 99% cpu use).
So what puzzles me is that I hear everywhere that Vegas 7 handles mpeg2 so well, while on my system performance is lousy, and worse than Vegas 6.

My Vegas 7 often doesn’t even play a normal DV file without any fx at full framerate in a standard DV project (yes, when all the settings are correct and opacity is 100% etc.etc.)
I posted on this before, but seem to be the only one for whom Vegas 7 works that bad (of course I’m happy that not everybody is having this problem).

[Arthur] “My V7 plays back m2t in a HDV project very very bad as well (about 3 fps with around 99% cpu use).”

My Vegas 7 on my laptop plays back m2t at about 25-30fps where Vegas 6 only gave me around 5-8fps. Vegas 7 is massively better at playing back m2t files.

I have had experienced some framerate issues with 24p HDV files, but have found 30p HDV files to playback as smoothly as standard DV AVI’s in Vegas 7. All of the HDV footage I’ve used has come from a JVC HD100 camera.

All this confirms that it is just me, everyone else is happy.
My troubleshooting pretty much narrows the problem down to the Vegas 7 program itself (since the exact same project plays on the exact same computer much better on Vegas6 than on Vegas7 with the exact same program settings).
They must have put something in Vegas 7 that my computer doesn’t like. Or maybe it has some kind of incompatibility with other software I’m running.
Since nobody shares the troubles, I’ll just stick to V6 and wait with V7 till the next computer upgrade.

I have similar problems with my HD playback…I was told by Sony to capture my HD stream and then save it as an Mpeg-1 to make it an intermediate file. Then edit that version…andd titles and so on…then save that edited stream. Then, right click on that one, choose replace and then find the original HD stream you captured and click open and it will automatically replace the un-edited file with the edited one and re-instate the HD aspects…

I don’t know if this really works because I can’t seem to replace the file correctly.

Does any one know how to do that?

[Arthur Bueno]

interesting advise. Basically it means you edit a proxy (but why mpeg 1, why not a dv proxy, like gearshift does?). Of course: editing a proxy gets rid of your playback limitations, but that’s not what I want, I’d want to see the HD material in as high a framerate as possible.

I am also sitting with performance issues in Vegas. I am using the Raylight codec to work with Panasonic’s MXF files, and my frame rate is poor.
But even more concerning is that Vegas 7e is proving to be very inefficient in general. When I render anything, HD, DV, MPEG2, my processors sit at around 16-25%.
As far as I know all my settings are correct.

Does anyone have any advice on this?

Something is amiss if you’re not getting real-time or near real-time playback of the MXF files.
Are you running anti-virus on the machine perchance?
