Rendering long clips
Posted by Harry Akkers on December 24, 2019 at 12:43 pmI find that if I a lot of small clips (totalling, say, 5mins) – these will render much faster. But if I have one long clip of 5mins then render times is exponentially longer, much much longer.
Does’nt make sense.

December 24, 2019 at 5:52 pmNo that doesn’t make any sense at all. What is the format of the clips, and what are you exporting to? Any effects applied?
If you could please share a screen shot of the Export Settings panel, that can often be very helpful in spotting potential issues, and fixes.
Thank you

December 27, 2019 at 3:15 pmOriginal clips are MP4 avch. It appears that when Premiere is rendering and hits a long clip it gets all wound up and goes into sulk mode. But give it a lot of short clips and its fine; sails along fine.
The clips have colour changes etc mainly through Lumetri.
Whar I have been doing lately is to highlight a long clip, render it and then move to next long one. Once all long ones are done, I just tel it to render whole sequence.

December 27, 2019 at 3:55 pmWorkflow tip that may help, if not already doing so:
- Create NEW folder on hard drive for each SD card you need to import
- Copy ENTIRE contents of 1 SD card to 1 folder. Copy ALL files/folders, not just video clips
- In Premiere, import using Media Browser, not File > Import

December 30, 2019 at 3:47 pmPoints 1&2 complied with but not 3. O always tend to import.
I am just curious, why does import burden the system and how does media browser help?
Thanks

December 30, 2019 at 4:42 pmWith certain file formats, things just work better in general when using Media Browser to import. Something to do with the way Premiere see/interprets the footage. I think Media Browser is looking at the bigger context of metadata/folder structure and all of that, versus “Import” simply grabbing the one clip as a stand-alone media file.
Some cameras record sound and video to separate files. Media Browser puts them back together.
Many cameras break long recordings, like over 20 minutes or so, into separate chunks called spanned files. I’ve done 2-3 hour stage events without stopping recording, and the AVCHD video on SD card (.mts files) is in several pieces of 4GB each for example. If you “import” all the pieces and assemble to timeline, you may have brief video and/or audio glitches/missing frames at the joints. If you use Media Browser it understands that the multiple clips are part of a single, longer recording and when brought in it will appear as one long clip, no breaks!
Just in general, you are much better off to use Media Browser when dealing with media from cards. If you just have a single video clip not from a card, like an .avi or .mov or .mp4, then sure go ahead and use FILE > IMPORT, that’s fine. When dealing with card media, stick with Media Browser for best results.

If you’re looking for efficiency, all H.264 clips should be transcoded to an edit friendly codec (i.e., cineform) prior to editing.

January 6, 2020 at 4:00 pmThanks. Do you mean transcode befire taking them to AP?
I already set the sequence setting to go previews in DNxHD .
