Ghost frame in timeline

[yvesmagat]

Adobe Premiere 13.0.3 for Mac (High sierra 10.13.6) on a MacBook Pro (15-inch, 2016).

When editing a video, one frozen ghost image starts showing up in the timeline at the beginning of some sequences. It's actually the last (and dubbed) frame from the previous sequence. It happens usually when I have moved/inserted a sequence right before or when I have done some other action: trim, lift or cut for example. It stays after rendering too but not on the exported video (in mp4). It's annoying when I insert a new sequence without deleting the first "frozen" frame of the next sequence: in this case the remaining frame is of course visible when exporting. Thanks for any help.

Delete preview files.

See how that goes.

  Thanks for the fast answer. I'm quite new on Adobe Premiere. I used to work on Avid Mediacomposer... How do I delete the "Preview files" ? Just by looking into the Adobe Premiere folder ? I guess it's not the "Delete Render Files" in the Sequence Menu ?

[Ann Bens]

Yes it is: Sequence/Delete Render files.

In Premiere rendering means making preview files.

Making the final product is called Export.

Hi Ann. Amazing. After deleting the Render files, it was OK. But then I thought I had to render again before exporting ( as I used to do on Avid , consolidate in this case) and the problem came again. Does it mean I don't have to render before exporting ? Or render first, then delete the Render files and then Export ? It seems strange. Thank you very much for your patience.

No you dont have to render. Only if if your preview codec is the same as the output codec then you can check Use Preview in the Export Settings.

As you are making a mp4 you do not use the preview files

Rendering the timeline is also done if your machine cannot handle playback.

Post a screenshot sequence settings and export settings.

YvesMagat,

With DVCPro, you could use smart rendering to speed up your workflow, but you need to change your preview codec to 1080 in Sequence Settings. Render out previews in the timeline. Export to DVCPro with the same settings, using previews. You would get out a master of your show very quickly that way. Create H.264 copies if need be from the master.

Thanks,
Kevin

Thank you all of you who answered. I did some homework on the web too and tried several options in the previews settings panel. I have the feeling the real problem was the 60 Hz settings in the Preview File Format. I had the ghost frame problem with P2 720p 60Hz DVCPROHD and with P2 1080i-1080p 60Hz DVCPROHD. But the problem disappeared using both settings with 50Hz or I-Frame only MPEG. Is it because I'm in Europe where 50Hz is the standard for camera and lights ? And if I understood correctly I should not check the Use Previews box when exporting in a different format than the source Previews (quite obvious !) Now I still don't know what are the best Previews settings when exporting into mp4 or mp2. May be it doesn't matter if the Render feature is not related to the export but just to the viewing of the timeline   . It's late here in Switzerland now. I'll check more tomorrow. Bye and thanks again.

I am still here; GMT+1

I frame is fine for mp2 or mp4 output.

Two other things.

H.264 if its for the web or simular set fields to progressive. (did your record interlaced: what camera?)

Turn off Max Render if you have a dedicated videocard.

[yvesmagat]

Hello again. I edit for both the web in mp4 and for TV broadcast in mp2. Thus the interlaced settings on my camera Sony Z150. About the dedicated video card, I'm frankly not quite sure... I don't know if the "Radeon Pro 460 4096 MB Intel HD Graphics 530 1536 MB" on my MacBook Pro could be considered so...

This fixed my ghost frame issue, but delete literally 50% of my footage :((
