hello adobe!
i know this a very long post, but this is the result of a compilation of issues we have discovered since 1 year of heavy usage in professional broadcast company. www.sette.com
many are related to captions and other to VTR
i will be at NAB show 2015 to ask in person about those to Premiere team.
. stripping audio to vtr with aja is OK.
.stripping audio with BMD is no good (vtr error), but works with fcp on same machine!
. bad sdi output when timeline in 29.97 and video file in 23.98. Should be so easy to do pulldown software...
. bad captions output on decoder broadcast when timeline+video 23.98 fps., hoppefully final export to mxf 29.97 embedded is good.
but the tc of 29.97 is ndf after this conversion. How to make it df ?
. even if captions (from dedicated video track) are good on SDI playback - after edit to tape they are scrambled up. We must use a SDI to SDI broadcast converter from evertz to have acceptable result.
. many dropped frames while edit to tape with captions. Removing captions track solve issue. this is a BIG issue for us, since we have to get back to an external encoder...
.import of captions fails for different type of mxf xdcam; some are not imported even in present in the file.
. SCC always appears as SD @29.97 in project info, even if 23.98
. premiere always think and import SCC file with ":" as NDF mode. ";" are mandatory for df mode... but there should be a option for that.
. the time code within SCC displayed by premiere is wrongly converted from the "discovered by premiere" tc SCC ... ex: my SCC is 23.98; premiere will show all captions with a TC 29.97!
. adobe MUST FULLY manage 708 cc encoding and decoding in mxf and mov, including forced transcode from scc608. as today premiere can only encode 608cc; whatever captions we throw in. besides, there is no way to see if captions are present in 608, 708 or both tracks.
. bug with some fresh converted xdcam mov or prores mov : premiere does not more detect audio tracks in timeline (have to completely remove asset and reimport)
.same bug but with captions not displayed. Reimport and the will appears
. media encoder ; what the differences audio track mono vs discrete ?
.mencoder : how about a "auto open in sequence" for file just encoded ?
.mencoder : issue with white bars for mov xdcam50 + captions. Encoder issue that shows white bar on the right into qt7 player. Not present if using apple compressor
.mencoder : please add SCC sidecar 23.98fps
.premiere captions long time decoding upon import mxf or prores. Improve, show captions tracks but only decode on demand while scrubbing/playing; or detect the CC track the ASK "do you want to import captions? this will take a while"; or permit to discard import of captions.
. sync parameters does not keep keyboard shortcuts. Nor workspace. ..
. why 2 audio mixers, 1 that really change volume on export (and other does not, not even applying audio volume effect), and 1 other that do the pan on export
.how to configure true audio compressor with max 10db, not clipping wall, but smoth curve
. GPU export. When will you use it to really encode the export with GPU ? As today only a very things ( not even displayed ) are GPU accelerated, like effects and resize. Cf telestream vantage light speed
.mxf 720p59.94 with CC : premiere doesn't like 720p resolution, not able to output any VANC SDI. Have to make 1080i timeline and scale up to full image. (a soft hack crossconvert 720p->1080i)
.Aja capture : default is stereo mode, how to change to mono ?
. export to file and export to tape. A big MISSING convert TC feature, so that we can convert ndf to df. 29.97and 23.98
.import of 4/3 anamorphic footage is forced to badbly forced to full frame, so you wrongly read of metadata (correct 16/9 par shown by mediainfo)
. bad display of captions with accented characters like "noël" (became "no el" with extra space) but its okay in QuickTime. Check for uppercase character like "noËl2
.bluray export settings. Wrong 16/9, result is 4/3 blue disc on TV. Have to specify 16/9 again on tsmuxer. When converting with others softwares like rhozet or vantage, this issue is not present.
.mencoder. Rename 'uncompress' audio to 'uncomp PCM'
.mencoder MISSING remap audio on export, so we should be able to keep source file with 8 tracks, and select 7-8 for stereo only export
.premiere . what about direct mxf xdcam capture/record? Same but cineform thing that you now do with cineform codec ?
.premiere. export to tape. Always 3 to 4 frames offset before on vtr. The little case 'video delay' does nothing. Not sure same behaviour aja and bmd. this is a BIG issue, we have to constantly measure the offset on VTR, then adjust the TC to export to tape the 2nd time. we can go up to 17 frames offset !!!
.custom sequence wrong framerate adjust: when i create a sequence xdcam50 1080i with 12 audio, and drop in a pal25 or 23.98nts file... and ask to "adjust sequence to file" -> bad result jutter. I ve to create sequence in native framerate first, then import corresponding video, then it's okay!
. In 23.98 timeline; the in point of the edit to tape dialog will AUTOMATICALLY change! !! In fact it's convert to 29.97fps when hit 'record' ! And also the offset is 3 frames instead of 4-6 in 29.97
. When exporting media from 1080i mxf to 1080i qt proreslt with captions; premiere add some extra 'cdt' and 'cdt2'
(this is due to the upgrade of premiere november 2014. it was without those bad characters before)
.export mxf 720p59.94 with captions. There are incorrect; many tools like rhozet and nexio server can not playback normally !
.how about adjusting automatically the startime of sequence to mediastart ??? So obvious.(for the first file dropped in new timeline) ..
.when we sync settings to cloud; presets for exporting media are NOT synced. Have to launch mencoder appart; and sync from there.
