@John-McKean Ok. I’m going to have an ice cream.

1440x1080 4:3 is not HDV.

Therefore, it is not 1.333 PAR. It is, by definition, 1.0 PAR.

Therefore, do not use the HDV template to create 1440x1080 4:3 video..

Also …

You deserved your ice cream JN, what should I try next?

My first project still is capable of doing 1440 4:3 rendering, just not my follow-on projects

@John-McKean I thought of this earlier, it's a kinda desperate remedy, but. Use you project that does work, while active, select all media and then delete. Then try loading and rendering a new piece of media.

If it works then continue. If you had a lot of media in the 2nd. project, load both projects then copy and paste all from the 2nd. to the 1st. empty working project.

@John-McKean Another idea, similar. I upload my project file to you that uses your test piece, then u see if it can render out correctly.

Thanks JN for the ideas and I will try them. I did try and load the exact same media file that worked the first time directly next to itself on the same timeline and it had the same error rendering but then tried to render again the first media file and it rendered fine

@John-McKean Aok. If you need the project file etc just post with @jn- then I will know, best of luck.

An older parallel discussion and link is here:

@John-McKean Can you check the internals of the different clips, maybe they differ?

I checked the clip against itself... that is the strange thing. The first rendering worked fine then the follow on renderings did not work but the first rendering file continues to work fine

@John-McKean Is there any need to upload my project with/for your clip?

I don't think so JN because my initial file rendered perfectly and still does, it's just the follow9-on files did not. I think maybe something is corrupted in my codex files

@JN- You have equivocated SAR, PAR, and DAR; the latter is what we are discussing here.

There's a good article on Wikipedia to help you keep from conflating the terminology.

https://en.wikipedia.org/wiki/Pixel_aspect_ratio

By the way, all of the information in your reply is correct, as it is in my original quote! Think on it a while.

Here is the annotated quote; however, it clearly implies display aspect:

"

1440x1080 4:3 DAR is not HDV.

Therefore, it is not 1.333 PAR. It is, by definition, 1.0 PAR.

Therefore, do not use the HDV template to create 1440x1080 4:3 DAR video..

"

@John-McKean Referring to the iink above,

• HDV is 1440x1080 1.333 PAR, 16:9 DAR
• If I read correctly, you want to produce 1440x1080 1.0 PAR, 4:3 DAR

I know this is new terminology for you, but the article should make it clear.

I don't think so JN because my initial file rendered perfectly and still does, it's just the follow9-on files did not. I think maybe something is corrupted in my codex files

@John-McKean Maybe that's it, no harm to check if there is any difference in the Mediainfo of the other files, though it may not show up there.

The only other idea that I can think of is, convert/transcode all files to Prores HQ in VP18, then use the Prores files on the timeline and see if you can get the output of 1440 x1080. Obviously try just a few first. The Prores files work well in VP and you should see no loss really in quality.

Ok, the problem with that is that I don't see how to get Prores to select 18 fps, but you could choose 24 fps.

Thanks for all the insight and ideas JN, I was thinking last night about it the fact that the one instance of the video rendered correctly and when I put the same instance of the video next to it it didn't render so it has to do with something with how I changed that particular instance a video in the timeline. I remembered I did do something different do it to change the aspect ratio of the file that renders correctly . here's what I did under Fx pan/crop to change aspect ratio.

pan/Crop

click Position

select Key frame

Lock aspect - unchecked

Source maintain aspect ratio – set to no

click Position change

@John-McKean Ok, so with a bit of playing around you may well be able to fix it!

JN, did you just download that dropbox video and rendered out to 1440 with no problem just like my first attempt?

@John-McKean Yes.

As per my post on the previous page … “Ok, I rendered out a 10 s section to 1440 x 1080 AR 1.33. Output FPS was to 25, then 18, still ok”

I think I've corrupted something JN

@John-McKean Well, if that means you’re getting closer to a fix, understanding of whats up, in a sense it’s good news.
