![]() ![]() It seems that Media Encoder is trying to render your video with the graphic card, which does not have enough memory for a particular frame to render. Save the project and then add it to render queue.Switch your After Effects project's render engine to "Mercury Software Only.".If you're coming from Premiere Pro, please checkout this guide instead. This is a guide for Adobe After Effects -> Media Encoder. If the QT movie is uploaded to, say YouTube, this gamma is stripped out as a matter of course.Sometimes, when rendering with Media Encoder, the rendering fails on a memory intensive frame. Stripping out the gamma setting 'fixes' this. This QuicktimeGammaStripper utility (for Windows) disappeared in the last few months, but it popped up here ĪFAIK the way QT displays your movie is NOT an accurate respresentation of the movie itself, but an attempt to adjust to the type of system you have. It's a very simple tool which operates on all the file names and folders given to it." To work around this issue, Frantic Films Software "created a small tool that strips the 'gama' tag out of offending quicktimes. While this is well-intentioned, motivated by the difference in display gamma between PCs and Macs, the Quicktime player offers no way to view this tag and change it. Deep within the file, there is sometimes a little tag called 'gama' lurking which tells the Quicktime player what gamma correction the file was encoded with. Quicktime has a feature, mostly hidden from users, which is designed to adjust the display gamma of quicktime movies on different machines to compensate for display difference. So Eric - if you too selected one of the "Alternate Download" presets, don't forget to provide it with alternate file info. (As did exports from the other, "lesser quality" presets). Once I did that, the QT export from AME worked fine. But I neglected to enter "alternate file" info for the export. Steven - Yes, you are correct - in my AME test I selected "QT Alternate NTSC Download" because the other QT presets seemed to define lower than best quality. This bug is planned to be fixed in a future update for Premiere. This setting can be saved as a AME preset for further use. Note: The default bit depth for QT Animation, QT None is set at 8 bit which needs to be changed to 24 bit or 32 bit (for Alpha) to get better quality. Export to AME Quicktime H264 hangs if work area includes any non-video. AME crashes when exporting to QT H.264 with QT source when the Video is shorter than the Audio Quicktime output with QT None codec is very poor in quality Quicktime output with H.264 codec is of poor quality ![]() Quicktime output with Animation codec is of poor quality Quicktime output with Photo JPEG codec is very poor in quality
