setting combinations to optimize output even when the user would prefer to make such choices manually and end up creating a file that is incompatible with QT-based media apps. The only thing special about Apple's H.264 encoder is its context adaptive nature that auto-adjusts the various Profile, Level, data rate, feature, etc. What does 'Quicktime variant of H.264' mean here? Are you referring to the MPEG-4 AVC compressed data or the file container? Data compressed using the JVT H.264/MPEG-4 AVC specification should should play the same in MOV, MP4, or M4V file containers whether compressed using the H.264, X.264, FFmpegX, or other third party, non-proprietary software/hardware packages. VID: Blackmagic Design DeckLink HD Extreme 3D+/Desktop Video v10.1.1ĭRV: Facilis TerraBlock 16TB RAID/ATTO ExpressSAS R680 v2.19 This information did not correct the problem:Īny help or ideas are greatly appreciated.ĬPU: 41.6GHz (dual octo-core Intel Xeon E5-2670 2.60GHz) but that's the breaking point for Adobe Media Encoder CS6 (6.0.3.1 to be precise) and H.264 Quicktime files. Testing this information to it's limits, I found that the cutoff for a successful render is between a frame size of 1610x9x905. More interesting still, it will ALSO export at 1280x720. Using the same original file (1920x1080), Adobe Media Encoder WILL export a 720x480/486 H.264 MOV file. Troubleshooting reveals the problem only occurs when attempting to make a 1920x1080 H.264 QuickTime file. Non-Quicktime H.264's render correctly, but some television stations require quicktime. While exporting the Quicktime variant of H.264 for ATSC television broadcast files, Adobe Media Encoder fails. I'm using Adobe Media Encoder CC 2014 on a Windows 7 Pro 64 bit PC.
