Adobe After Effects CC - How do i downscale videos in size?

[LienFilm]

I just imported a 40mb video in Adobe After Effects and added the Warp Stabilizing effect. I then rendered it and became a 3gb video file (1920x1080). Is it possible to render it as a smaller file, but retain a high resolution?

Reason being is it that i am going to add the Warp Stabilizing effect to a 2gb video file, and even though my hdd is around 1tb i have a bad feeling it wont be enough

After Effects will render to a variety of codecs at a variety of bitrates. Further, you can drag your sequence into Adobe Media Encoder for even more options. So yes, it is quite possible to render a smaller file and maintain resolution.

What you haven't described is what type of file you are using -- codec, duration, bitrate, frame rate, field order -- all of that information is available in the project window. (Or use Mediainfo for even more precision.) Nor have you described your output render settings -- default is usually uncompressed avi which will certainly result in large files.

Does his screenshot help?



My output settings is currently set at default (uncompressed avi).

After Effects installs with a user guide: https://helpx.adobe.com/after-effects/using/converting-movies.html#scaling_a_movie_down

The internet has lots of videos like these: https://www.youtube.com/watch?v=IPmtFZZJ29A

There's not a lot of info about that video. Is it interlaced? Try MediaInfoXP to get more details about video.

Okay, your project shows that your files are run-of-the-mill AVCHD mts files. 1920x1080 interlaced (indicated by separating upper.) 48000KHz 32bit audio -- probably AAC since it's straight out of the camera.

Take a look at this tutorial to be sure you know how and why to get your compositions into Adobe Media Encoder. (You can also simply drag your composition from your AE project window into the AME queue.)

With your material, as a starting point, you should try one of the DVD & Blu-ray presets in Adobe Media Encoder.
Specifically, start with the HD 1080i 25 H.264 Blu-ray preset.
In the Audio tab, switch from PCM to Dolby Digital
In the Multiplexer tab switch from none to TS

This will give you very good quality at a slightly higher bitrate than your original. As I said, use this as a starting point -- experiment with different parameters from here.

Yep, that's the way I "almost" recall doing it way back when I first got AE. It was so much trouble I ended up doing it in Avisynth and encoding with something else. Never cared for Adobe's encoder.

I tried this and it works wonderfully. Thanks a bunch
