View Full Version : Verify rendered sequence

Hello, is there anyway you can verify that an image sequence is rendered without any corrupted frames after the render is finished? Sometimes After Effect spits out corrupted frames wich corrupts project files (crash) when imported wich can lead to serious problems some times.

So far i can import sequences (in a new AE project) and play them through to see if any crash occurs, but that's a very tedious procedure especially when you have longer sequences (10x 4000+ 2k frames to deal with for example.)

Any tricks or external tools i can use for this?
And is it even possible to make them work in conjunction with AE?
It would be sweet if a verifyer tool could be launched and verify after a render is finished automaticly.


Any thoughts, experiences or ideas on this?


Thanks

What corruptions? If they occur frequently, they certainly have a verifiable root of evil like network timeouts or fragile disk configs. Anyway, you can use pretty much any image viewer that offers a slideshow or batch conversion feature - if they fail to load a given frame, you can reasonably be sure the image is damaged. those tools could also be used to repair broken files, if e.g. only the header is damged, but the actual pixel content is intact. Try XnView or IrfanView, should be a good place to start as they are both free for non-commercial use.

Ranch Computing (http://www.ranchcomputing.com/framanip.php?url_back=M_index.php) also offer a free image sequence viewer, it can tile-display a bunch of frames at a time. Doesn't offer any repair tools, though.

From my experience with AE corrupted frames, they tend to have a zero k file size (or close to it). If that's happening to you, you can find them easily by viewing your render folder in list view, and sort it by file sizes.
