To overlay a half-sized version of a video in the center of an image, use ffmpeg -loop 1 -i image -i video -filter_complex "[1]scale=iw/2:-1[ovrl]; [0][ovrl]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2:shortest=1[v]" -map "[v]" -map 1:a -c:v libx264 -c:a copy output.mp4 To frame the video: ffmpeg -loop 1 -i image -i video loop 1 -i ...

That's called: Banding. About Color Banding from Wikipedia: Colour banding is a problem of inaccurate colour presentation in computer graphics. In 24 bit colour modes, 8 bits per channel is usually considered sufficient to render images in Rec. 709 or sRGB. However, in some cases there is a risk of producing abrupt changes between shades of the same ...

It is probably worth checking your Image>Mode settings. I find they tend to change my colours between exports and prints etc.

Windows Server is very much the same as the Desktop Windows regarding the core of the OS, there is just some stuff missing and other stuff added that is usefull for webservers. You shouldn't have any problems installing an After Effects render node, I used Windows Server 2008 R2 myself for an After Effects CS5 network render node. Shouldn't have changed ...

There seem to be a few basic misconceptions here. For cartoons you don't need anything fancy as long as cell-shading is supported, which is typically a camera filter. Lighting is actually done in your 3d animation software. The job of a render engine like Mental Ray or V-ray is simply to process the scene you build to generate the final image, but it ...

I think you have answered your own question, but let me try to answer it from the perspective of a programmer (not one who wrote After Effects, but one who has written a lot of programs and seen a lot of source code). After Effects (or any other compositing program) operates on layers. Layers can be combined, masked, or used as inputs to transformations or ...

You can use ffmpeg, a free command-line tool, for this. Syntax is ffmpeg -framerate 25 -i img%04d.png video.mp4 where img%04d.png is the pattern mask for a list of image files named img0001.png img0002.png img0003.png ...

Adobe Premiere Pro allows you to create caption files (including SRT) and export them individually (as SRT files) or embedded with the actual video. This link gives a pretty good overview of how it's done in Premiere.

Use ffmpeg -i C:\src\assets\video\base.mp4 -i C:\card.png -y \ -filter_complex "[0:v][1:v]overlay=x='if(eq(n,439),300,0)':y='if(eq(n,439),300,0)':enable='eq(n,438)+eq(n,439)'[out]" \ -map [out] -map 0:a -ss 17 C:\temp\j7kthb0v\composit.mp4 You may need to escape the commas in filters depending on your shell i.e. n,438 -> n\,438

I normally use ProRes 4444 set to "RGB + Alpha" and "Millions of Colours+"

Yes, this is possible. Simply right-click your logo in the Project-Panel and select "replace file", then select your new logo.

do i get you wrong about you want a lossless compression? https://trac.ffmpeg.org/wiki/Encode/H.264 Choose a CRF value The range of the CRF scale is 0–51, where 0 is lossless, 23 is the default, and 51 is worst quality possible. A lower value generally leads to higher quality, and a subjectively sane range is 17–28. Consider 17 or 18 to be visually lossless ...

Have you read Adobe's system requirements for Premiere Pro? I think you'll find that a GPU is absolutely crucial for Premiere renders. Looking at your specs you seem to have got everything fairly well specced up except for the one thing that will massively decrease your render times for PP. TL;DR: get the best GPU you can afford.

There is no such thing as 60fps GIFs. GIF files store delay time between frames in whole hundredths of second, so it's impossible to make a GIF with exactly 60fps, because value 1 would give you 100fps and 2 would already have half of that - 50fps. Besides that, many programs (including Google Chrome) ignore value 1 and defaults to much slower animation ...

The gif format doesn’t work like this. You won’t be able to get an animation with this high a frame rate. The good news is that many sites which claim to use GIFs actually use mp4 files. I don’t know your exact workflow, but you could try making an mp4 at this frame rate and uploading it to one of the “GIF” sites.

Just subtract the first frame index from the expression: overlay=x='n-438':y='n-438':enable='between(t,438/25,450/25)'

I have been able to at least 10x render times in AE (depending on hardware) by rendering to image sequences and running multiple instances of AE on one machine. Because AE is so inefficient at using your resources you can get away with this in direct proportion to your hardware. I don't have a good rule of thumb for how many instances to run at a time but ...

I would try using a seperate ssd for your project files and assets. You'd have one for your os and software and one for the project.

You won't be able to render it to h.264 because of the odd number of pixels in the vertical resolution (odd as in not even, not odd as in unusual). You simply can't encode h.264 video with odd numbers as either one of the frame dimensions, that's just part of the codec. This is true for quite a few codecs (any that use macroblocks). I actually can't think ...

Are you using the inbuilt After Effects render queue? It's a bit easier to use custom settings when you use the Adobe Media Encoder instead. AME comes with After Effects and is installed automatically when you install AE. Simply open the composition you want to export in After Effects and select Composition → Add to Adobe Media Encoder Queue. This will open ...

Generally, all of your assets should be converted to the same frame rate as your final output frame rate before you begin editing. If you do not convert them beforehand, you may have issues with timings. Things that are supposed to be one length end up being a different length. This is especially true if you export a variable frame rate file. Suddenly a 30 ...

I'm not an economist, but I have built and run a small render farm. I'd make the decision on a ROI basis: will you get back a return from your investment? I can't answer this for you, you'll need to add up all the costs for both options and compare. Costs for a physical render farm are mostly fixed - i.e. the capital outlay, but you have to factor in ...

Had the same problem. Put a black solid in the background. It worked for me.

Don't do the frame rate change in Photoshop. Do it later on in AE. Export all 30 frames from Photoshop, then import them into AE. Make a new comp in AE, setting the new frame rate as 12fps in the comp settings. Right click on your image sequence and choose "interpret footage as 12fps".

29.97 is the NTSC compromise for 30 fps. 23.976 is the NTSC compromise for 24 fps. 29.976 is a framerate that results from confusing these two numbers into a single bit of nonsense. The bottom line is that if you have a mix of 29.97fps and 30fps, then every 1000 frames (about every 33 seconds) there's going to be a glitch. Either you have to double up a ...

Once the Rotobrush tool has been selected to use (assuming you used Rotobrush based on the pink outline) a small box in the bottom right of the comp will appear and should say "Freeze." Literally just press that and it'll freeze the mask... fixed my masking render glitch and I hope it does for you too! Best of luck, happy editing.

I solved my own problem after some more trial and error. For awhile it looked like the fact that I was using Mental Ray shaders combined with general shaders was the problem, but that didn't really make sense so I kept tweaking. It turns out that an image plane I had tied to my camera was the problem. The image on the plane never rendered out, so I assumed ...

Might be an issue with the smart rendering option available for MXF in Premiere/AME. Try disabling that. http://blogs.adobe.com/kevinmonahan/2012/10/11/smart-rendering-in-premiere-pro-cs6-6-0-1-and-later/ If that doesn't work. Render an intermediate and re-import and encode that to MXF. Though keep in mind that MXF is just a container, you have different ...

It sounds like the image isn't actually transparent. I am not familiar with kdenlive, but any decent NLE should allow for transparent layers. As long as the images actually have transparent backgrounds, it should just work to animate one layer coming in on the other. I would try using GIMP to make sure to remove everything but the line itself from the ...

I've never heard that term used for rendering before, but it is most likely referring to the number of hours of computation needed for a single CPU or GPU to process it. In most video and 3d applications, it is possible to parallelize the rendering of the video itself (though not necessarily the encoding. Thus, a job that would take 200 "man hours" (more ...
