Aharons work flow tutorial – overwrite pieces of the same file?

[Aharon Rabinowitz]

Well, if you’ve rendered uncompressed and then found an error, you can just re-render the part containing your fix, and then combine them again in AE as quicktime clips. In other words set them up as layers on the timeline and line up the fix over the right time.

This will render much faster then re-rendering the whole project.

If the audio is the same, turn off the audio for the fixed layer. If you’ve also corrected the audio, render out a seperate audio file and add that to the comp as well.

I listend to the tutorial. Thank you Aharon, yet again!

I have a thing that bugs me about AE and this end of it. When I render out an animation I usually render out to a .mov to then import into Avid. I will watch the rendered out .mov and decide I need to make changes. I then add it again to the render que and hit render then get the error that the render is aborted due to file being busy. The problem is that I still had the movie player open, or just the file name highlighted in a navigator window. I then have to re-add the animation to the render que. It won’t let me re use the same queued item. That bugs me. If I duplicat the render I tem like you do in the Tutorial that should work then?

Thanks for reading, I feel better.

Select the one you originally duplicated and hit CTRL+D

So you hit CTRL+D

Try to trender but it fails

Instead of clicking the failed render and duplicating, go back to the first one.

I usually render to image sequences. If I see a couple of frames that need to be re-rendered, I check the frame numbers in the comp (CMD or CTRL click on the time-code in the top left of the timeline viewer to switch from seconds to framenumbers).

I delete the frames that need to be rerendered from drive and I render to the same image sequence again – with ‘skip existing frames’ enabled in the output module.

The only downside of that is if you must deliver a quicktime. Dealing with image sequences slows things down for NLE’s, and AE, so often people prefer QT video. But if you aren’t under a constraint (like your client ore editor is OK with image sequences) then that’s an awesome way to do it.

Thanks for that, Barend.

If my final delivery format is Quicktime, I’ll deliver a Quicktime of course. But usually I’ll render to image sequence first, if it’s a slow rendering project, and then convert the sequence to whatever deliverable is required. When I’m working on film based projects, it’s usually image sequences that I get, and they want the same back. But in broadcast I usually deliver movie files.

I’m assuming that the only reason you’d want to replace only a segment of a movie instead of re-rendering the entire project is that it’s a slow rendering project. Otherwise it’s more convenient to just re-render the entire thing.

Now, about image sequences. I find that many people feel uncomfortable with image sequences, because it can be somewhat daunting to see tens of thousands of .tifs in a folder.

There are a couple of benefits to rendering to image sequences though:

1. Network rendering. You can’t have multiple machines render to a single file. I often have a couple of machines chunking away at a render overnight.

2. Crashing. If your machine crashes or the render fails during a render, sometimes the partly rendered file is corrupted – forcing you to re-render the entire thing. When rendering to image sequence you just restart the same render (skip existing frames) and continue where you left off.

And then there’s the somewhat more exotic benefit of being able to render to .EXR files for HDR projects.

I’ve had plenty of projects where we had bad tech issues (crashes)or tight deadlines (network rendering) and rendering a sequence and then re-outputting to MOV was the only safe choice. But converting a large image sequence to MOV can take a long time. I used to be all image sequence crazy, but these days, unless I need to go to image sequence, or I’m under the gun, or having technical issues with a render, I tend to go the route of quicktime.

I did a (for me,) MONSTER AE effect for an end of a Military video I produced. This effect sits at the end of my FCP sequence. Well — our bosses want to show this thing to every General that comes on base and, of course, personalize it to them. So I have to change a single 3d name in the midst of these 10 precomps, 15 additional layers, cameras and lights — well, it only took me ONCE to realize that if I can just set the work area to the change and render that out.

BUT — after 3 times doing that – still a hefty render – I did one final render turning off some of the layers and rendering it out 3 times with Alphas. The Names sit on the middle layer now in FCP and when I need it changed, I just render out that name from that layer and it goes VERY quick.

I know that’s a little different than making a mistake… but it did make me think about the way I compose and organize all my future AE messes.
