It’s also possible that a combination of factors is in effect here, so that on other machines, where the factors differ in some way, the problem doesn’t present itself. My experience is that writing anything out of the VSE from encoded video source material can be problematic – not always, but often enough to be cautious. I see it as a matter of trying to isolate the problem from the initial steps, so starting with the original source material (sounds like for you that’s mostly video footage), keep that constant while trying out different ways too get it into Blender without the corruption you see. I really can’t say that’s the solution, but it’s definitely a new workflow path to try out. If you can consistently repeat the problem with various original material sources, this could also be grist for the bug-crushing mill. If AE always writes clean, then it’s a Blender problem and perhaps worthy of a bug report.Īlso to keep in mind is that the motion tracking module is still very new and may have undiscovered bugs that only widespread use on various OS configurations and in various workflows will reveal. If both apps write corrupted frames, then there’s a problem with the original material, outside Blender’s scope. Your idea to write a PNG sequence of your original video material from another app like AE is a good “control” against the same steps in Blender. In either case, this could be the source of the “corruption.” The VSE does not play universally well with all video/movie formats and codecs some source video encodings have been reported creating issues not unlike what you’ve experienced, as well as other problems. But as I understand it you’re using either video footage loaded as a movie, or an image sequence made in Blender from just such a movie loaded in the VSE. Maybe something like this is occurring with your work comp?įirst, sorry if I’m not grokking this all completely, I haven’t yet done any tracking in Blender so I’m not all that familiar with specific processes, just general principles. It can actually crash Blender & my entire system, but in no cases are the files being displayed altered or corrupted in any way, they just look like crap on screen due to the graphics card bollixing out on me. I have experienced serious issues with the display of images in Blender (and other apps) due to the ancient and obsolete nature of my graphics card. Do the “corrupted” frames consequently show the same problem when viewed with another app? If not then the files themselves are not being corrupted, just not displayed properly in the VSE. Do you mean that the corruption happens regardless of the codec being used?įor a file to be “corrupted” when being read means that it would have to also be overwritten in some fashion, and that just doesn’t happen when loading an image sequence into Blender’s VSE. Ĭan you post an example of the “corruption”? There’s no way Blender could “corrupt all codecs,” so maybe I don’t understand what you’re saying with that comment. Problem is not as concise as this thread, because I was still trying to figure out what was going on. I’ve posted thread on Blender Cow but no one responded. ![]() ![]() You wouldn’t imagine the work arounds to get by with this at work. I would be so thankful if someone could help me fix this. And here’s what blows my mind, it corrupts frames in an image sequence when it caches them in the movie clip editor! It corrupts files when it’s reading them! Crazy, right? ![]() Not every frame, but often enough for it to be royal pain. I was hoping someone could point me in the direction to fix this, because the only thing I can think of is to reinstall the OS which I don’t have time to do at work.Īnyways, the problem is, Blender, on my work computer, corrupts frames. I suspect that this problem is very system specific because I’ve never had it happen on any other computer, and no matter what version of Blender I use on my work computer the problem persists. I’ve been experiencing this problem for a while on my work computer.
