Hi Owen, So just to clarify, you are wanting to import the images in their full size, and then scale them down to the timeline? It will be helpful if you can tell us what size the images are, in pixels, and the size of the timeline you are working on. ... View more

We have had similar issues to yours, where trying to import via Windows Explorer (for any reason -- footage, projects etc) just randomly freezes the software. My best guess so far is that this is linked to the network setup that we have (our team is at an educational establishment with various rules and complex network setups), but have so far been unable to properly pin down a reason. ...

With the text method that you are using, do you mean that the video appears 'in' the text? For the track matte key method to work, the image will have to be in black and white (for the luma to work) or an alpha channel. Perhaps if you can provide an image of what you want to achieve, we'll be able to assist. ... View more

I have had this before, and if I remember correctly, I have found that this either refers to a file that isn't in the timeline, or to render files that have been cleared out at some point.   One trick is to type "offline" into the search bar of the project window, and this will reveal any missing clips. Have you attempted to export the video? Usually, it will export just fine if the clips it needs are indeed online. ... View more

You need to open the multicam sequence from the bin, and you will see that the clips are all set up on different tracks. Identify the clips you wish to adjust, and add the effect to those.   ... View more

I think this is something that could probably be done by creating a script using Adobe Extendscript coding. I also think this may be more easily achieved in After Effects, particularly as there is a bit more information out there for writing scripts for AE.   I don't have the experience to advise much further on this, but some useful resources I've been exploring recently are as follows: https://www.youtube.com/watch?v=UutXfHp9KDg https://www.youtube.com/watch?v=x90MacNDMu0 http://codeandmotion.com/   There are also some great coding folk on the AE forum here, and over at Creative Cow who are very generous in helping with this kind of thing. ...

Hi Matoos. Does the error occur as soon as you drop the clip into Premiere, or does it only happen as soon as you apply an edit on the timeline? Could you provide some details about the type of clip? ... View more

It would be interesting to understand your system setup, in particular where the 4K clips are being stored. If you are not running from a fast external drive, it may be that some clips are too heavy for the setup to cope.   With a deadline approaching, I would definitely be exploring ways to reduce the file size so that you can at least get the edit done. A proxy workflow would help here, and depending on the final delivery (for example if the project is not for broadcast) I would try converting some of the problem files to something less intensive on the processor (looking at the camera setup, I am presuming that they are H.264 recordings, which are notoriously processor-heavy to edit due to the high level of compression). ...

Actually, the same rule applies no matter how large the image. As soon as you are scaling footage over 100% the image is technically pixellating. In an ideal situation, you should only ever have to scale footage down, and no higher than 100%.   When you drop a 6000 x 4000 px clip onto a 1080 x 1080 sequence, it will be way too large to fit on, so you will scale it down to 20%, for example. Say you want to scale to focus on a particular part of the clip, you can do that without over-pixellating, as long as it doesn't go above 100%. Any higher than than, the pixellation will be occuring. ... View more

Ok, the best way is simply to not 'scale  up'.   When you import an image or graphic and drop it on the timeline, it will overlay 100%. If the footage is too small for your frame, you should always find a larger version of the footage. As soon as you have to scale the footage above 100% (in the effects controls panel) the footage is technically pixellating.   Depending on the purpose of the video, I will sometimes allow a maximum scale of 120% if I really can't find a larger clip, and it will not be noticable, but it isn't good practice to do so.     ...

I'm not sure if I fully understand what you are trying to see here, but I want to point out that video doesn't work in the same way that still images do. Therefore, there is no 'DPI' to speak of in video.   The most appropriate way to assess video quality properly (i.e. professionally) is to use a broadcast-standard external monitor, although in the age of majority-online video, very few actually do this these days. ...

Nishu is correct, if you can identify the point in the sequence where the problem is caused, you can take measures to replace the footage or component that is causing the issue.   If this happens to me, I break the timeline down into sections, and just export one section at a time, until I have found the part of the sequence where the export is failing. I keep narrowing down until I have found the problem section, and replace the footage, or create a new clip with the existing file etc.   One common problem I find when exporting is images. If they are particularly large in resolution, they often cause exporting issues, and I recommend making the image smaller in photoshop and re-importing. ... View more

I may be wrong about this, but I don't believe it is possible to 'relink' an audio track in order to use the audio from another source.   There are two ways I would consider approaching this:   1) Produce a multi-cam sequence to merge all of the footage onto a single track. 2) Group the matching clips together (by highlighting the matching clips, right-clicking, and selecting 'group'. Then you can edit on the timeline in the Program window.   If you just have one camera and a second audio stream, I would choose the second option, personally. ... View more
