Continuing image sequence render from crash point
I’m not in front of my workstation right now, but…
I’ve been trying to (I know, I know) change a 20min-long, HDV-60i, monkey-on-my-back to 24p in After Effects. I know how to do it. I know what should be happening. It’s just not working. It simply crashes after about the 800th frame. (oh, and I know about the secret menu memory tricks too, no luck in helping this particular issue)
I’ve tried direct copy and paste to After Effects from PP2, but had the unfortunate experience of whole-system-failure on several attempts. So, I rendered the thing out to a flipping huge huffyuv (40G+) file and imported that with at least the success of getting it started in the render process. Now AE just crashes after a while, letting me save to a backup copy before exiting the program. It is however generating beautiful frames for the first few minutes of video.
My thought now is that it should be possible to render this in sections, but I don’t actually want to have to cut the thing up (I probably will anyhow, I just don’t want to) to render in shorter blocks. Too bad there’s no way to render the png sequence until it dies, then start from the last rendered frame and continue. Of course, I tried “multi machine render” but it seems to only allow the “keeping track of frames” in the linear render time of the, well, render; thus accounting for the multi-machine concept, I suppose.
If anyone knows a trick that’d help save my slowly deteriorating brain please do tell.
If I have to go back and render it out to a different format that will work better for the conversion (including a tif sequence/etc…) I could.
Not the right forum, I know, but can Premier render out from chapter point to chapter point into separate numbered folders?
Or can I split the chapter points to separate sequences in order to port them to AE in smaller sections, thus skipping the crappy PP2 render stage entirely?P.s.
This is a mess I’m cleaning up, not one I made. -

Setting a new beginning point is a good idea, especially if it sticks on certain frames. You could also try setting the time length to “custom” in the render queue setup, and prepare a number of different renders to run sequentially… a few minutes at a time. You could try with 2 in order, and if it works, you could set up all the items in the render queue and walk away… almost like a single render.

If your AE render to sequence filed fails, just restart AE or even a hard reboot, and head on to the render queue. Select the comp name and goto the edit (or comp – can’t recall) menu and choose duplicate with filename.
You’ll get a new render item. Look into the Render Settings dialog window and you’ll notice that AE automatically changes your in point to reflect where it last saved your seq – IOW when your system crashed.
Granted, if it was a stupendous crash, then chances are that AE may not have been able to save the required data.
An alternative is to import the entire Premiere project into AE using the File>Import> menu. Just select Premiere Project and that should be a better option than copying and pasting between the two apps.

Thanks for the response, I’ll try it out tonight when I get back from work. I really think this is only happening due to the length of the clip. 20:01.01 seems a tad taxing on the AE render system. I’ve never had such issues before.

Make sure you select “skip existing frames” in your render settings. When you restart your render (if it’s an image sequence) it’ll automatically start at the first unrendered frame.

I cheated on a whim with this one. I didn’t have time after work to mess with it and was frustrated enough that I did something dumb/genius instead.
Since I was working with a tif sequence of 1440×1080 files and I think the immense size of the project was causing the problem I set up a Photoshop script to convert the frame size down to 720×480. I set it to convert the whole tif file sequence and left for work this morning. When I got back all was Peachy. I am 68% through my final AE render now (after some tricks). All color issues I had already taken care of in PP2 (though I wouldn’t have done that normally, just this project has been causing issues for a while for me). This final render is an output module of a master and another output module for the m2v. Finally I can move on.I would not recommend this conversion process to anyone as it is time consuming; however, it does let you bump the bit rate if you want. I did.
