Tmpgenc and Premiere Pro

[SoupStain]

If I do a simple video capture (in DV format) using Premiere Pro. I can encode with Tmpgenc no problem.

However, if I edit the video (eg trim the end point) and then try to encode the resulting file with Tmpgenc, the 'preview' screen in Tmpgenc stays blank and the program makes no progress on the encoding (stays at 0%).

The simple capture and the edited file both play fine in Windows Mediaplayer.

If I edit the problem file in Windows MovieMaker2, then I can encode the new file again in Tmpgenc.

Can anyone shed some light on this problem?

A clue to the problem might be that when I read the problem file in Tmpgenc, it seems to load too quickly for the size of file.

Look at the codec used by premiere pro ... may be you have to use the same as in moviemaker ...

dlawedor,

Thanks for your suggestion.

Do you think that Premiere Pro (or any other capture/editing program for that matter) uses a different codec when it does a straight capture than it does when it edits a clip? I will check and see what codecs my files use like and post the result.

Why not use MainConcept that comes with Premiere (at least it came with 6.5, see no reason for it to not come with Pro), out of curiosity?

lordsmurf,

The reason I want to use good old Tmpgeng is that I want to encode the file to half-D1 resolution, and the MainConcept encoder which comes with Premiere Pro doesn't allow me to do this.


dlawedor,

I have checked the codec for each of the files using AVIcodec, and it says that both files use the same codec, so I don't think this is the problem.

I have looked at the file properties of each file from within Premiere Pro and I notice that there is a difference in the "Interleave" field. The straight capture has a ratio of 1 : 2.00 and the exported file has a ratio of 1 : 24.79.

I have posted the question on the Adobe support forum, but if anyone here knows what might be going on, I would appreciate their advice.

premeire pro will encode to 1/2 D1 , i just tried it ..

BJ_M,

You are obviously a lot more experienced that I am in using Premiere Pro. I can't seem to work out how to encode to half-D1.

Can you explain how to do this, please?

Thanks,
SoupStain.

[SoupStain]

I guess not :(

BJ_M,

Do you have a future version of Premiere Pro?

According to Mark Bailey at MainConcept, the current release of Premiere Pro does not allow you to encode to half-D1 frame sizes...

Unfortunately, in Premiere Pro the frame size options are not exposed. This is beyond our control because we supplied the MPEG encoding technology but Adobe rolled it into their Adobe Media Encoder interface. They are aware that this is an issue, and I'll check periodically for progress on it.

I wish I could suggest an effective workaround for the moment, unfortunately that is out of our hands.

Anyway, the problem of Tmpgenc not liking my exported files was just a question of adjusting the priority of the directshow filter.

i never noticed you said you were encoding to mpeg2 , which i wouldn't do in premiere anyway , i was talking about encoding to avi ..

but to encode to 12/ D1 mpeg2 , just frame serve it out
