Faster Export with Only Small Change

PostFri Mar 13, 2020 3:17 pm

Is there any tricks for faster exports on long shows when making one small adjustment in the middle?

For instance, in other software, putting an already exported file on a top track of the sections that don't change (leaving a gap were you've made adjustments) will process the clip much faster. Provided you use the same compression as the first exported file.

Thanks.

Select "Bypass re-encode when possible" on the Deliver page.

If you have heavy renders, use one of the image sequence formats if you have to expect some changes like that and overwrite the part in question. Then encode the whole show from that. Has been done in CGI for the last 30 years (at least).

+1

On an intensive program, i output a dpx version, and create a timeline from those files that gets output to my deliverable version.

The advantages:
Big renders in a 90 min show only need to be rendered once. Subsequent renders are only for the individual shot changes, which automatically replace the dpx files, and repopulate into your deliverable timline.

Your first dpx render might take a while, but any future changes will seem quite fast, because you are doing individual shots.

Once I QC the initial render of the dpx's, I can relax a bit, and concentrate on any new changes only. (One of the issues with heavy renders, is it might have an issue this time, that it didn't have last time)
Having to re- QC the 90 minute output for every client approval pass becomes a PITA. With a previously viewed set of DPX's, the chance of a glitch in the approval pass is pretty small.(if you trust your system).

The Cons:
The initial dpx render will take up a lot of space.

EXR 16 bit saves some space.

I like this approach. I wonder if this would have simular time exporting changes to the "Bypass re-encode when possible" selection that John Paines points out? I'll have to look into it further. Thanks for the advice.
