Why must I re-render a nested sequence?

When I nest a fully rendered sequence into a master sequence I need to re-render much of the audio and some of the video in the master sequence even though when I check back to the original all of the render files are intact.
This flies in the face of all the research I have done about this. Every article I can find on nesting says the render files will be preserved. In fact, Ken Stone suggests using nesting in certain instances to keep from having to re-render constantly!

As diffkid has implied, the setting must match precisely. But you may be confusing renders, that create new media files, with RT stuff that does not require rendering in the upstream nest but maxes out your RT capabilities in the main downstream sequence. Say you have six audio tracks in your nest and then you place that into a sequence that has 4 tracks but your system is set for 8 tracks of RT audio. You've got to render the audio. Same with your video effects. Everything is cumulative.
However, if you are actually rendering upstream, the pointers to the render files SHOULD hold. They don't always and I have no idea why.

Why can't I render to match sequence ?

Hi there,
I have quite an irritating problem.
I brought in an effects I did in AE which is in 1920 x 1080.
Then in Pre Pro, I also set the sequence as 1920 x 1080.
When I render, I did Export > Media. I chose "match sequence settings" but the output is always in mpeg format which I cannot change (it is the only format availabe).
So since I need to render in mov, I cannot use "match sequence settings", I select Quicktime. For the Preset, there is only NTSC & PAL DV widescreen. How come there is no option for HDV ?
As it turn out, when i click export, the output is in 720 x 756.
How to I get Premiere Pro to render in 1920 x 1080 ?
Please help me, I am desperate !!
Thanks
Cheers

Well, as I recall, AIC is limited to 1440x1080, using non-square pixels. I'm surprised that Premiere doesn't automatically reset the height and width values, but maybe that's only for non-QuickTime formats and codecs, as it uses its own export module. You will probably have to manually set those dimensions (1440x1080) and PAR (1.333) if you want to export using this codec.
That said, why do you want to use this codec? It's an intermediate codec (and not a very good one, at that), not a destination codec. What do you want to do with your file?
EDIT: Just checked on my Windows machine, and with QuickTime as the Format, dimensions do change depending on the codec selected. DV and DVCPROHD, for example, are locked, but other codecs can be changed to suit the source and destination. If you choose AIC as the codec, and the dimensions appear locked, please post a screenshot...
Thanks Colin & Bill,
I didn't realize below the Codec chosen there is a vertical slider to surf down & change the dimension. The default for vertical & horizontal was 720 and 576, so I changed them to 1920 and 1080 and it worked. Not sure why the default was 720 & 576 but oh well ....
Colin, I select AIC simply because it says Apple Intermediate Codec ... I thought because I was using an Apple computer so I select it. Okay, what would be a good codec then ? I wanted it to be able to watch on a computer in HD.
Thanks

Nested Sequence issue: keyframe scale setting changes after rendering?

Hi,
I'm using PremierePro CS5.5, and have been having this same issue since CS4. After nesting a group of clips, I make the timeline effects entries to animate the nested sequence. For this example, let's say I start at 00.00 with the scale set at 150%, and end the sequence with the scale set to 300%. Just zooming in. Looks OK, so I hit return and render the nested sequence. It plays back, all is good, but after it stops the 00.00 setting magically changes to 100% or some other percentage. I've tried everything I can think of, from selecting Hold or Linear for the keyframe, to deleting all the keyframes and redoing the settings. It only happens with nested sequences and it seems to only be the scale setting that goes flukey. Anybody else have this happen and could you tell me what I am doing wrong?
Thanks,
Christy

Thanks for checking it out Jim. It doesnt happen every time, you know how that goes... just often enough to drive me batty. I'm doing animated whiteboard videos. Lots of short bits of video layered with graphics and stills, some effects, then all that is nested and sometimes the rate compressed. Then I zoom in a bit and that seems to be the last straw. Maybe I am just doing too much? It's a simple, uncomplicated look to the finished piece, but it takes a lot of cuts and tweaks to get it that way.

Why does my nested sequence need rendering?

Folks, I have a twelve sequences that are fully rendered and I am nesting them onto one timeline. The new timeline has the same settings as the other sequences. Why do my already rendered timelines require rerendering on the nested sequence? Is there any way around this. It would seem there's some way to take already rendered sequences and line them up on one sequence without having to rerender.
The project is XDCAM EX 1080p24

Nevermind folks, I figured it out. I had my render control settings set to Apple Pro Res on some timelines.

Nested Sequence and Maximum Render Quality

I use quite often nested sequences and sometimes within nested sequences. Do I have to check the flag Maximimum Render Quality in each sequence setting or is it enough to have it marked in the root/top sequence? I guess, I have to. Is this correct?
regards,
Claus

For exports the checkbox in the export settings dialog overrides all others. For preview rendering make sure to check it on the top sequence in which you are rendering previews.

Does a nested sequence keep its render?

I have a nested sequence within my Main Sequence.
Within the nested sequence is Adobe Dynamic Linked clips to After Effects.
I cannot edit these while un-rendered.
If I take the hours to render the data within the nested sequence, and then when moving that sequence in the main sequence, will Premiere have to re-render the initial data?
Or, does it have a memory of the data that is rendered within the nested sequence so it won't be as graphic intensive?

Run a short test and see for yourself.

Why does my nested sequence have only one channel of audio?

Hi,
Working in Prem Pro CC on my Mac Pro.
I have a number of interviews, each shot with 3 cameras and with audio from a separate audio recorder. The audio has two channels, Ch1 has the boom mic and Ch2 a radio mic.
I created a sequence, placed the audio into channels 1 & 2 (they are linked) before placing the video tracks onto timeline tracks 1-3. Everything's synced nicely and so I nested the shots and then I enabled multicam on the nested sequence.
However, now when I edit the nested sequence into my edit sequence, it has only one channel of audio. I tried Modify>Audio Channels but within that page, in the option to select 'Source Channels' the options are "None" and "Channel 1".
How do I get my nested sequence to place both audio channels into my edit sequence?
Any help much appreciated.

Nevermind folks, I figured it out. I had my render control settings set to Apple Pro Res on some timelines.

Why is my nested sequence layering the effects?

Hey Everyone,
So after I color correct my master clips, I sync them, remove the unwanted audio, then nest them. BUT, in the nested sequence it seems that all the video tracks layer the video effects throwing my nested sequence in a horrible color landscape of overexposed or over colored clips! Can anyone help me?
Mike Diaz

JSS1138,
I apologize for the confusion, I'm new to Premiere CS6. When I import my master clips, I lay them on their respective video track 1, 2, or 3 because I usually only shoot with 3 cams (see screen shot) I label them for what camera footage they are: Camera 1, Camera 2, and Camera 3. Then I bring them into the sequence on individual tracks stacked so Plural Eyes can sync them on top of what will be my main audio recorder. Then Plural Eyes imports the all the video and audio clips back in Premiere but now all the video clips are in sync with my main audio source. Now I will have a sequence with 3 video tracks with their respective clips from their own camera synced up but not color corrected or nested on one video track yet. This is where I color correct each camera on their own video track and apply to the entire camera's footage. But the problem is when I nest all the video and audio tracks together, it overlays the effects instead of leaving the individual camera with its own effects.

Nested sequences change aspect ratio of clips underneath them

Premiere Pro 6.0.5
Mac Book Pro Retina
See attached screen shots:
1. Nested sequence is off - everything under is is crisp and proper aspect ratio
2. Nested sequence is on - everything under it is blurry and wrong aspect ratio
3. Only nested sequence is on - so you can see it does NOT contain the layers underneath it by mistake
Why is this happening? It's really troubling... It generally happens when I go to render my sequence - it goes all haywire wrong aspect ratio when rendered with that transparent nested sequence above everything.
Image 1:
Nested sequence is off - everything under is is crisp and proper aspect ratio
Image 2:
Nested sequence is on - everything under it is blurry and wrong aspect ratio (it gets pushed up - see black line that is formed on the bottom)
Image 3:
Only nested sequence is on - so you can see it does NOT contain the layers underneath it by mistake

Crap... I noticed that this glitch now spread to even clips that have NOTHING above them. The scaling is wrong, and image quality gets a bit blurry after rendering. It always squishes my clips up after rendering, but they look absolutely perfect pre-render.
New example:
1. Clip 01 - Opacity slightly turned down to destroy the rendered preview - looks perfect:
2. Clip 01 - Opacity all the way up, clip rendered wrong - bottom squishes up. Whyyyyy:

Image in nested sequence does not let me export my project

Hello,
Here's my issue:
In my Premiere project, I have a "Master" sequence in which I have normal a/v files and two nested sequences, for the video intro and ending.
The problem is with the nested intro sequence, which is composed of several images that I've animated, plus sound. I've narrowed the source of the problem to one specific image in this sequence, which is 5760x3240. I've read in other threads that images larger than 1920x1080 can be a problem, but couldn't find further info.
What happens when I try to render my video in 1080p with this image in a nested sequence is the encoding fails with AME giving me this log message -
" - Encoding Time: 00:00:01
09/22/2014 10:45:46 PM : Encoding Failed
Export Error
Error compiling movie.
Unknown error."
When I try to render in 720p with the image in the nested sequence it works fine. When I take the image out of the nested sequence and just put it on the "Master" sequence it also renders just fine, even in 1080p.
So my question is - why can't I render my project if I have this image in a nested sequence, and if possible, how can I fix it?
Thanks in advance.

Hello again,
While trying to do what you told me I've come across something interesting. Apparently it's not only that one image that's responsible for the problem. Here's how I have it setup:
Premiere for some reason seems to have trouble rendering the still image "BG2.png" (1920x1080) AND the problematic 5760x3240 nested image at the same time. As "BG2.png" does not actually appear until later, I tried cutting it just before the point where it should appear. With that, AME was able to render the video until the point where "BG2.png" started, then it failed again. So I checked in the nested sequence and also cut the 5760x3240 image (because it appears briefly in the start of the sequence then has its oppacity set to 0, it wasn't a problem). So what I had was the 5760x3240 image cut after it appeared (instead of just turning down the oppacity) and BG2 cut before it appeared, that way those images didn't overlap in the master sequence. With that, AME was able to render it just fine. So I have no idea why, but those 2 specific images won't let my sequence render when they ocuppy the same time. Any ideas?

What happens to previews in nested sequences?

For the sake of keeping this simple, If I were to have a
main/master sequence comprised of
2 nested sequences
When I render (preview) out one of my nested sequences (not just effects, but the entire work area), why don't I see my timline turn green on my main/master sequence? It seems to stay yellow or red.
I have all the sequences set to render the same (Cineform High-HD).
I want to save time on final renders by using the preview files, but are they even available if I haven't previewed on my main/master sequence? If I did preview rendering on any sequence deeper inside the master, do those even get used or does Premiere ignore them?
I rarely would preview out an entire master sequence. Most likely, as the projects are never as simple as my above scenario, I have some nests that go 10 deep. Sometimes the best place to do the render preview is 5 nested sequences deep.
What happens to the preview files on nested comps? When you turn on "use render previews" when exporting, does Premiere dig deep through all the nested sequences to utilize that info?

Bummer. So they are essentially useless unless you can build a complicated 30-minute TV show on only one single sequence (which would be a total mess).

Trouble with nesting sequences

Hello.
The "transparent" elements of my sequences are not preserved when I bring them into another sequence/timeline and apply an effect or motion to it. Is this typical? They appear to be fine, at first, but when they are rendered or exported, the nested sequence has a black background instead of a transparent one. I'm working targa files with transparent elements, which work just fine in their source sequence.
I apologize if my wording is awkward or if this has been answered elsewhere.

This is not my experience.
When I add transparent elements to a sequence and I nest this sequence into another one, transparency is preserved, even after rendering (I can superimpose the sequence with transparent elements to another clip in the timeline, and this appears in the transparent areas).
Exporting is a different issue. FCE can Export/Quicktime Movie only using DV or HDV codecs that do not preserve transparency. There is a possibility however: you may Export/Using Quicktime Conversion and select the Animation codec which preserves transparency. But before exporting you must make sure that the sequence is not rendered, otherwise the non transparent rendered files will be used (to do that you can make the tracks not Visible and then Visible again, in order to delete the render files; or you can disable and enable again the transparent clips).

Media Encoder CC 2014 using cached versions of Precomps in AE and Nested Sequences in Premiere?

I'm seeing this weird thing where Media Encoder is using older versions of certain assets when exporting a Premiere Pro CC 2014 sequence. I'm seeing issues with nested sequences...Media Encoder uses an old version of a linked AE comp or it doesn't render a certain video track. With linked AE comps...I'm seeing Media Encoder use an earlier version of a precomp within the main comp.
When I look at the video in the Export Settings dialogue in Media Encoder, the old version of the AE comp shows .
If I look at the Export Settings dialogue in Premiere, it's up to date and looks right.
Anyone dealing with this or found a workaround? Thanks!
Calvin

I don't think I'd call this issue expected behavior...at best it's anticipated behavior that's going wrong. The only reason I wouldn't call it expected behavior is because what I'm seeing is AME reverting to a cached state on a FRESH LOAD of a sequence to render directly from Premiere. Basically, AME isn't open...sequence looks fine in PPro...load into AME via PPro export...look at export settings dialog in AME and note that the sequence is the old/cached version. So, it's not like the export was already in AME and THEN I made changes in PPro. It appears AME might be incorrectly identifying the newly imported sequence for export as an older, cached version.
However, I didn't get a chance to test your original solution so I'll try that the next time I see it happen. I also fixed the issue by clearing out the media cache and databases. NOT an elegant solution at all and TOTAL overkill...but it did work.
Thanks for the links!

Each edit is taking 5-10 seconds to process in some of my project file's nested sequences. What can I do?

I edit a weekly news show. For this show, I have created a Project File that I re-use as a template every week. It's a highly nested template, with a sequence for every used material (the anchorman’s footage, the news set, the media playing over the anchorman’s shoulder, the lower thirds, etc). It has three different camera angles in a multicam sequence, each sequence sharing the same nested sequences but just resized to look like a different camera angle. To make this easier to understand, here's an episode (explicit):
SKATELINE - Cory Kennedy, David Gonzalez, Jimmy Carlin In Enjoi Oververt and more.. - YouTube
In the past, the template has worked perfectly. However, everytime Adobe has a major update and I update the project file, for some reason, some of the sequences perform very sluggishly. With Adobe's recent update, the sequences for the anchorman’s footage and the media playing behind him are very slow to make edits in. Every action I do takes 10 seconds to process, even moving an image. However, if I work in the master sequence (With everything put together) everything runs perfectly smooth when I make edits.
In an attempt to fix this problem, I decided to recreate the project file from scratch, with the new update, but even then, my "anchorman footage" and "media behind him" sequences are very slow. What's even more bizarre is if I select a piece of footage in the anchorman sequence, my entire program sometimes crashes. I have tried rendering the sequences to help performance, but that hasn't worked. I have tried installing CUDA Drivers to use the CUDA version of the Mercury Playback Engine on my Macbook Pro Retina, but it also still isn’t working.
So why do you think that my sequences are operating so slowly? What could be causing it? Could it be that each sequence is used several times in the multicam sequence? If so, why has it worked smoothly until now? What can I do?

Yes same issue for me also, working in mutli cam nestings
Very Very Sluggish Performance, semi hangs in PP, if you actually wait long enough, or leave it hung whilst you do a post on here, for a few minutes then it may come back to response.
The issue is defo to do with nesting, I have tried turning off audio wave forms, which helps in the multicam nest edit but as soon as you put that sequence into a third nest then the sluggishness is major.
Basically, this looks to be the same issues that have been reported before with the new update.

Changes to master nested sequence not updating in new sequence

Good morning - I have spent the past half hour or so searching the forum for this topic but have not found the answer. If the answer exists elsewhere, please point me in that direction; otherwise, here goes:
I created a nested sequence by simply dragging one sequence (A) from the browser into a new sequence (B) in the timeline. Later, I went back to Seq A and replaced all of the audio (which was in-camera audio) with clean audio from a Tascam field recorder. So far so good. However, Seq B still plays the original camera audio and is not reflecting any of the changes I made to Seq A.
I tried deleting audio render files, quitting and restarting FCP, etc., all to no avail. I have the latest versions of the OS and FCP. Any suggestions would be much appreciated.

As you've probably found there are several ways to create/edit nests into sequences. The manual points out an advantage of using nested sequences is you can make a change and that change will be reflected in all the subsequent nests. As you've also found out, this isn't exactly true.
The only way I've found to have communications carry forward to nests from the original sequence is if I edit the sequence into another sequence via the Canvas overlay/edit keyboard shortcuts from the Viewer. I've found dragging and dropping to do as you've found.

Why must I re-render a nested sequence?
