New to Premiere--thanks for any advice.

 

I'm trying to export a timeline sequence to an mp4. When I did export it--the timeline completely jumbled-whole sections of images were missing, clips I did not include in the edit appeared, etc. It was so strange...I have no idea why...

 

This is what the timeline looked like. So I went back to an earlier autosave and created a new sequence to export as an mp4 to a high-quality HD setting.

I wanted the image to fill the screen at 100% but it was set to the following below. When I try to reset it for 1920x1080--I get the following message. I'm afraid to select anything. Is it ok to follow-through? Thanks.

Any time you change anything about a sequence, any previews will be no longer useful, so it dumps them. No problem at all, they're just previews.

 

Curious about the non-square pixels ... any reason for the .9091 PAR setting? What's the media?

 

And what's going on in the area with diagonal stripes on clips?

I never figured out what happened with the media and the stripes--it took out a big portion of my project as I exported it. I think it was user error as I was copying the original media to another external drive for someone else to edit on the timeline and with the relinking, I messed up my file structure. Thanks for getting back to me.

Moving media and relinking, especially if the files have separate audio, can be problematic. Yea, that happens.

Media files are generating when you render your timeline (without exporting). its fine if those got delete.

As for the missing/confused files. most likely you moved some files around and Premiere recognized/links other files with the same filename from a different source.

 

It is always a good practice to rename your files comprehensively, in a way that there will be no way for duplicates. (ex: Project_Date_CameraName_CardName_Original Filename)

To start with, take a look at the properties for the footage and make sure that it matches the sequence settings.

 

This is what has gone wrong from start, you have editied on a DV 720x480, interlaced, Lower Field First timeline and probably placed 1920x1080 footage on it and use the Position/Scale to "move" the footage to the intended place in the video frame. Then you have changed the sequence settings to 1920x1080 but still keeps all other settings, iow Pixel Aspect Ratio to DV NTSC (0.9091), Lower Field First while it should have a Pixel Aspect Ratio of 1.0 and either Progressive or Upper Field First. This results in sections of video missing in export.

 

Thumb of rule:

If the footage is 1920x1080, 29.97, Upper Field First, the Sequence Settings should be 1920x1080, 29.97, Upper Field First and the export should be 1920x1080, 29.97, Upper Field First or 1920x1080, 29.97, Progressive if it is intended for the web.

 

When using footage X on a timeline with Y setting and export with a X or Z setting you will have problems and the export will look bad. Avoid any mis-match.

 

So make sure to know your source footage, right click on it and choose Properties. (See image below) Make sure that the Sequence Settings match the settings of the source footage. Then you have to manually reset the properties for the clips on the timeline that you have adjusted Prosition and Scale to get back on track.

 

Short version:

The issue is not the setting you use when exporting, the issue is the settings and workflow you used when you started the project. 🙂

Thanks for the response. Much appreciated. Premiere was consistently freezing for me as I was working, even though my Mac had a lot of memory available, other programs closed, etc. Someone told me to move the source footage folder from the external hard drive that I was locating my files and move it to my computer desktop to work from there. The idea was that it would be faster if I worked from a folder directly on my desktop. I did offline the files and relink them but it exported completely strange--actually putting in clips in the timeline that I had cut much earlier. 

 

Any thoughts on if that's possible that the external drive can be too hard to work from when in Premiere? My Drive (WD easystore) has 12TB and 10TB free. I like that filename structure though so there's that to be sure I do next time I build a project.

Thanks for your reply. I filmed 4k with a SonyA7iii. When I click on "get info" on my Mac on the clip I get the following image (see screenshot above). Does this show all that I need to see? Still learning how to film and understand the terms correctly...

 

For the timeline sequence, I was importing the 4k clips to a 1920X1080 setting and then resizing the clips from 50% on up on the timeline because I was exporting to HD High Quality and thought it was still ok to do that up to 100%. I think that's what you are saying perhaps messed things up--plus not having the correct settings on the timeline sequence settings when I imported the files to start with.

 

As you can see I have some really wonky settings for my timeline sequence here. So for the 4K footage exporting to 1920x1080 do I need to follow the settings you mentioned here? 

 

"If the footage is 1920x1080, 29.97, Upper Field First, the Sequence Settings should be 1920x1080, 29.97, Upper Field First and the export should be 1920x1080, 29.97, Upper Field First or 1920x1080, 29.97, Progressive if it is intended for the web." Thank you!

Ok-so I'm right-clicking on clips inside the Project Bin in Premiere and I see Properties vs. Get Info and it says more of what you are talking about... I'm surprised the framerate was 23.. I thought I set it at 29...

You had a DV setting in the timeline you posted in the first post, that´s the same resolution as a DVD and very far away from 4K. That will cause problems.

 

Using 4K footage on a 1080p timeline is not "wrong" and can have advantages if you want to reframe the footage for some reason. But it is more convinient, IMHO, and timesaving to edit 4K in a 4K timeline and upon export just export to 1080 and be done. That requires no fiddling with Scale or Set to Frame Size when editing. It is a godsend to edit 4K in a 4K timeline the day you want to export it as 4K. Both ways has it´s advantages and dis-advantages.

 

I have indeed done the same mistakes as well back in the day and what i learned was to always know my source footage (resolution/framerate/pixel aspect ratio) to save time and have the sequence settings match the footage. 

 

Generally it is ok to edit with external drives but it can be challenging sometimes. For best performance it is best to use an internal drive, but not always possible,

Hi 

Looking for the right settings to create a 4K timeline. I shoot 4K with a Sony A7iii with plans to export HD. Any suggestions? Again, thank you!

The easiest way is to right click on a source clip in the Project panel and choose New Sequence From Clip. Then i would go to Seqeunce > Sequence Setting to double check that everything is correct.

Premiere has quite a few "moving parts" that can balk up the working playback. From the media itself, as say H.264 is far more difficult for NLE playback than an intraframe codec, to the location of the cache & media files. They all matter.

 

Cache files need space, and they need fast connections to the CPU/RAM and other subsystems.

 

Media files also need space and fast connection, preferably on a different drive than the cache or OS/Program files. Many external drives simply can't maintain the sustained speed needed, but some can.

 

TB3/USB3.1 and higher, with appropriate cables and specialized SSD drives like the Samsung T5 model can at times provide enough fast external access for media use. ESATA ... external SATA ... was a 'thing' for a while a decade back on higher-end laptops, and I had one with that. I could run an external drive and sustain above 4GB/s general use with it, nearly to what an internal drive could provide. But they stopped working with that connection.
