Thanks for the email.
The wg-test.mov and the AVI and MP4 files in the corrupted exports folder played for me just fine using Pot Player. I've asked a team member with AE to try it there (tomorrow, it's night for him now).
Spine 4.0 uses our own code for exporting video. Some users reported that some players refused to play the videos, while other players are fine. We have been unable to determine why that happens, as we are writing the video formats according to their specs. Here's a user who reports differences in colors on many different players. Video playback is complex and difficult to get right.
Spine 4.1 uses ffmpeg for exporting video. That's an extremely popular open source library which should produce video files that are widely compatible. it also provides more codecs and other options.
If you go back to 4.0 and still see video playback problems, my guess is it's your player being unable to deal with the video files. Does AE tell you what codecs it's using?
Both 4.0 and 4.1 export PNGs the same way, except 4.1 adds optimization options. Those use technology that is in the latest launcher to reduce the file size of the exported PNGs. If you uncheck the Optimization checkboxes then it should export PNGs identical to 4.0.
Figuring out why PNGs don't open correctly is much easier than video. If you can post or email a PNG that doesn't open correctly, we can take a look.
Actually he tried now. He was able to open wg-test.mov and WG-eyes.mp4 in AE, but not WG.avi:
HandBrake was able to open WG.avi. It's hard to say why AE doesn't like the AVI!
We exported an AVI with the default settings (PNG codec) and AE failed. Unchecked Transparency, still failed. AE can load AVIs using JPEG or MPEG4 codecs. Could it be that AE doesn't load AVI that uses PNG? If it can load MOV using PNG, maybe that is the way to go.
