So I have been using blender for youtube video's I've been making, since I need a free/open source video editor. I've been rather satisfied with the editing itself. With the rendering however, I have not.
I have rendered a 40 minute video in both Blender, and Adobe CS5 Premiere.
Settings used for BOTH blender AND Premiere
- 1 video imported
- 2 images (intro & outro fade)
- 1 music track (outro for about 15 seconds)
- Audio Codec: AAC (same as source)
- Audio Rate: 192 kbps (same as source)
- Stereo Audio (same as source)
- Resolution: 1080p (same as source)
- Framerate: 60fps (same as source)
- Video Codec: H.264 (recorded in x264)
- Video Rate: +-8000 mbps (same as source)
- Format: MPEG-4 (same as source)
- GOP size: 30
- Tile Size: 256x256 (seemed to be the fastest?)
- Start Resolution 64
- Output: Xvid
What I found was fairly displeasing.
Blender takes up to 6 hours to render the video, and produce a file of about 2.5 GB.
Adobe Premier takes about 1 hour to render the video, and produce a file of about 1.9 GB.
Both programs I have configured to the best of my abilities to fulfill the recommendations set by Youtube/google, which can be found here: https://support.google.com/youtube/answer/1722171?hl=en
Not only this, but whilst monitoring my components, I found the following things:
Blender uses 5 GB of RAM, about 20% of my CPU and about 5% of my GPU.
Premier uses 2 GB of RAM, about 75% of my CPU and about 1% of my GPU.
So my question is: Can I configure blender in a way that it performs more favorably? (like Premiere)
I can accept it if it renders for say 2 hours, but if you take over 5 times as long as is required (apparently), then that definitely means I'll not be continue using blender for editing video's.
