This is interesting. I disable audio in After Effects too but it is giving me mp4 in the end.

Here are how After Effects render settings look:

Yes, i thought the same thing at first so i checked but the multiplexer was set to “mp4”. Here are the settings i used in Encoder:

Video tab settings:

Format: H.264
Export Video: Enabled
Export Audio: Disabled
Frame rate: 23,976
Field order: Progressive
Aspect: Square (1.0)
Tv Standard: NTSC
Profile: High
Level: 4.0
Render at Maximum Depth: Enabled
Bitrate encoding: CBR
Target Bitrate: 10 mbps
Keyframe Distance: 72
Use Maximum Render Quality: Enabled
Use Previews: Disabled
Use Frame Blending: Disabled

Multiplexer tab settings:

Multiplexer: MP4
Stream Compatibility: Standard

I am getting a mp4 file (as i intended) when i use these settings at After Effects. But when i use Media Encoder with the same settings somehow it gives me a m4v. Here is a screenshot of the summary section in the Media Encoder’s export settings window:

The file seems to have a “.mp4” extension. But once i render, it ends up being “.m4v”.

@Jim

I didn’t select the “H.264 Bluray” preset. I selected “H.264” and customized several settings (like bitrate, aspect ratio, etc) in the same way for both.

Actually, Media Encoder shows the output as a .mp4 file before the render. But after the render, the output somehow ends up being a .m4v file.

Any other ideas?

[Engin Osmanovski]

By the way i need the output to be “.mp4”. I have no idea why i get “.m4v” with the Encoder.

@Dave

I was working on a very simple and 4-5 seconds long project. I encountered that delay even at basic keyframing.

@Ridley

May i ask where you read that? A link would be nice. Thanks.

… Or is that lag behaviour ineherent in multiprocessing regardless of processor specs?

[Engin Osmanovski]

@Tom

Multi-processing was on. I turned it off and now there is no lag. But i still don’t understand. Isn’t multi-processing supposed to speed things up? Why does it cause this delay???

@Dave

I didnt give any information about it because i didn’t have that problem before. I am still on the same PC. Anyway, here are some system info:

– i7 3770K
– Geforce GTX 670
– 32 gb RAM
– 1ssd + 1hdd

Do you guys think this system specs might be the reason i am getting that delay when Multiprocessing is ON? Is my processor too weak for multiprocessing?

[Engin Osmanovski]

What if i render the composition in AE with lossless compression and then transfer the output to Media Encoder and re-render it to Mpeg2? Does this method have any drawbacks other than having to render twice?

[Engin Osmanovski]

If i am not wrong, it will work with a 7200. Just won’t work efficient/fast enough with only 1 disk. They recommend “at least” 2 (1ssd + 1hdd) internal disks for AE. (More is better). It is a matter of separating the read and write process. The more you distribute these tasks to different disks, the more performance you get.
