Premiere Pro およびMedia Encoder CC 2017におけるバグフィックス情報のまとめ

Premiere Pro CC and Adobe Media Encoder CC | Creative Cloud blog by Adobe

（上記ブログより抜粋）

These releases also contain several hundred bug fixes and improvements; a list of notable ones appears below.

Premiere Pro

—Proxy—

• Ingest Copy could only copy reference file, which results in an offline clip and proxy failure
• Create Multi-Cam Sequence command could initiate an ingest process
• Search was not working reliably for proxy media
• Interpret Footage changes were sometimes not correctly applied to Proxy and/or Hi-Res media
• Speed/Duration, via Clip options, was disabled for clips with offline full res, but online proxy
• Paste and duplicate in Project panel could initiate an ingest process

–Import—

• MXF media with non ASCII AS-11 metadata could lead to a crash on import
• Premiere Pro could crash when turning layers on and off in dynamically linked After Effects composition
• Importer errors / async timeouts for MPEG MOV files have been resolved
• Certain ProRes .mov files imported as audio-only, without video
• Some QuickTimes files were imported as Audio only file on a machine which does not have QT installed

—Audio—

• Audio channel bleed and intermittent distortion was sometimes encountered when track panning a stereo clip that had been remapped to be 2 stereo clips
• Memory allocations were being ignored when conforming audio files and this could cause a crash
• Flattening a switch audio multi-cam clip that had audio effects applied to the source audio could cause a crash
• QuickTime growing files waveforms were sometimes constantly regenerated and never saved
• Situations where audio missing warnings appeared in console and audio drop-outs were heard have been resolved
• Certain cases where creating proxies would transcode to wrong number of audio channels and will auto-attach the proxy file have been resolved
• Razor cutting the audio inside a multi-cam source sequence could cause the waveforms  of the nested multicam clip to display incorrectly and partially disappear
• Audio would sometimes be missing when rendering at 50% after rendering In to Out
• Convergent Design Odyssey ProRes clips could have distorted audio.
• No audio was sometimes heard on playback after applying Maintain Audio Pitch with a Speed change
• At low audio card buffer settings, Playing across silent (and scrubbing) areas of audio could cause noise
• Repeated audio could play instead of correct audio when using “Maintain Audio Pitch” in Speed/Duration dialog

— Playback/Rendering —

• Occasional stuttered playback and freezes could occur in SDI Transmit image in 720p 59.95 playback with scaled image composited
• Render issues with masks/blur were sometimes encountered when using ProRes as preview files
• Poor playback performance could occur with PQ encoded RGB 444 12 bit J2K MXF
• Artifacts were sometimes rendered when using the “Blacks” control to adjust black areas on HEVC (H.265) media
• GPU accelerated playback of H264 media on Window was slower than software only in some cases
• Waveforms were sometimes drawn scrambled in MXF growing files.

— Miscellaneous—

• Using control surfaces to control Lumetri color wheels could freeze Premiere Pro UI entirely
• Placing a Red Giant Magic Bullet effect on a clip within the timeline sometimes caused a crash
• Situations where it was not possible to get out of full screen mode in Source and Program monitors after playback have been resolved

Adobe Media Encoder

• Win7 only: After some operations, AME could crash on quit
• Crashes could occur when exporting projects containing multi-cam
• Ingest Copy could only copy reference file, which results in an offline clip and proxy failure
• Export via QuickTime could fail if exporting with the Animation codec and an audio codec other than uncompressed, giving a “compressor format error”
• Native interlaced DNxHD .mov exports sometimes imported into Avid Media Composer 8 with no video image
• QuickTime native codecs sometimes failed to don’t smart render PAL sources with non-square pixel aspect ratios
• Changes made to After Effects comps inside a Premiere Pro project sometimes weren’t reflected in an export queued to Adobe Media Encoder
• Smart render of AVC-LongG material from a Panasonic camera sometimes failed, with a bitrate mismatch
• MPEG-4/H.264 proxy presets would sometimes increase the frame size, rather than decrease it, for unsupported interlaced frame sizes
• Clips inside Premiere Pro projects viewed in the Media Browser would sometimes incorrectly import as sequences
• Match Source for Batch Export could result in mismatched video codecs, rather than giving a compatibility warning
• QuickTime audio files .mov audio exports always had a 29.97 non-drop timecode even if the originating sequence was not in this frame rate
• Exported AVCi MXF media sometimes had incorrect DisplayWidth and StoredWidth metadata

なお、「現在把握されているバグ」については、広くユーザにとって影響が大きく、かつ明示的に発生する不具合以外に関しては、まとめた形での開示をしておりません。しかし、影響を受ける範囲は限定的であってもプロフェッショナルユーザにとっては影響の大きい問題については、なるべく早く公開していけるよう努力していきたいと思います。
