HD Encoding?

[jfharper]

For HD encoding, I have targa image sequences from 3D software rendering, edit with premiere and encode to Picvideo avi using almost noncompression settings. I've been using handbrake mp4 with average bitrate around 3000 kpbs, and the quality is sort of pixelated. The end file will be played from a computer on a big screen in trade shows.

Is there a better way to encode HD, or should I just up the bitrate, use a different encoder or ? Thanks for any guidence as I'm learner HD encoding.

higher bitrate usually required for HD; 3Mbps is quite low for most content (especially if it's "full HD" 1080p)

you can use "quality" based encoding in handbrake instead of a set bitrate (different types of content might require more bitrate, low complexity content will require less, so setting a bitrate isn't necessarily a good way of doing it)

Ah, thanks. Is there a quality range that is most used? Just an idea would be helpful.

You'll probably want to double it. You can squeeze good quality out of a lower bit rate with Handbrake, but for this project, you might as well just shoot the works.

Maybe around CRF 16-22 , lower values give better quality, higher bitrate

I think handbrake uses a % quality slider, so maybe 60-90% (higher values give higher quality here)

I would avoid using set bitrate, because it really depends on content complexity. If you arbitrarily chose 6Mb/s, it might be too little for complex animations, might be too much for simple content.

But using "quality" based CRF encoding, it will deliver the appropriate bitrate for that quality level selected proportional to the content complexity

You can set the CRF with Handbrake under the video tab:


For h264/x264 video I usually choose CRF 16 which only causes a very slight drop in quality.

Thank you.
