Export MPEG-2 without recompression

[Koby Goldberg]

Hi Lance, thank you!

When you say “Edius Procoder”
Do you mean EDIUS NLE software ?

Or PROCODER format converter ?

[Koby Goldberg] “Tim,
What software did you mean ?
Something like Brian suggested ?”

Sure…the thing is that you’ve done this with DVD MPEG2 most likely…AVCHD and HDV have some pretty straightforward and rather tight standards and I’m not sure you can manipulate the GOP lengths and still have a file that is recognizable as AVCHD or HDV when you’re done.

[Koby Goldberg] “Is it like a Video Editor for MPEG files”
Yes

[Koby Goldberg] “that combines and cuts parts of it without recompression”
Usually if straight cuts, or drop-ins for the same material its mostly without recompression except to mend the cut GOPs

AVCHD should be used with a intermediate codec like cineform, neoscene, the compression is so high it can choke most systems when codeding/decoding, the loss with transcoding to a intermediate codec is minimized by going by going to a higher bit count and quantization.

Thank you very much guys !
I will check out the VideoReDo software you’ve mentioned.
I will also check the mentioned EDIUS if it can provide what I’m looking for. From what I’ve read, EDIUS uses MPEG2 natively and uses the powerfull PROCODER compressor for exporting, maybe it can change the GOP sizes and recompress only the needed parts. If it does, it would be more convinient for me than the VideoReDo because of the full NLE capabilities EDIUS can offer (Transitions, Effects etc.).

If you have any other ideas or software I could also try, I would love to hear!

Thank you all again,
Koby.
