What Is The Max Bitrate For Youtube

Nigh every day I upload an HD video to one of my YouTube channels, whether information technology be a vlog, Q&A video, a skit or something else. I really enjoy nearly everything about YouTube: the community interaction, editing, the creative outlet it provides, even the weird looks I get when vlogging in public! But the matter I can't stand is that it oft takes 2.v to three hours to upload my content. If I consign my video from iMovie using the default 720p HD (Loftier-Definition) settings, information technology takes my approximately 10 minute vlog and creates a file around 750 MB. Since I already have the fastest upload speed that's bachelor at my location (1 Mbps), the only mode to decrease my upload time is to lessen the file size.

Encoding my videos to H.264/AAC is already a pretty loftier pinch and is also arguably the current industry standard (unless you lot enquire Google, apparently), just fortunately there's some flexibility within that compression to go an fifty-fifty smaller file size past adjusting the bitrate.

Very simplistically, "bitrate" is the corporeality of information each frame contains. The higher the bitrate, the more than information the video contains, which makes for higher video quality and thus a larger file size. The lower the bitrate, the less information each fame contains and the lower the quality producing a smaller file size. Bitrate is measured by the number of bits per 2nd.

My Un-Scientific Quest for the Optimal Bitrate for YouTube:

Since virtually of my videos are uploaded to YouTube in 720p HD, I wanted to know the maximum bitrate they use to encode my video. If I requite YouTube a file encoded at ~10 Mbps and information technology re-encoded it to 2Mbps, then I knew I could reduce the bitrate when I encode my video and upload something smaller and likely however become the aforementioned result.

For my unscientific tests, I downloaded the MP4 of many 720p HD videos from YouTube beyond many different users and channels. I likewise downloaded their FLV counterparts, which were actually 854×480 loftier quality videos, not true 720p Hard disk. Since I don't know if Google plays with their encoding settings from fourth dimension to fourth dimension, I only checked videos that were newer than one week. I used VLC to monitor the variable bitrate peaks and Mac'southward "Become Info" to check the video file property's total bitrate.

Hither's what I found:

Maximum Playback Bitrates on YouTube

FLV HQ: one.5 Mbit/south (variable bitrate with peaks of iii.0 Mbps)
MP4 720p: 4.0 Mbit/s (variable bitrate with peaks of 5.0 Mbps)
MP4 1080p: viii.0 Mbit/s (variable bitrate with peaks of ten.0 Mbps)

This tells me that encoding my videos at 10 Mbps for YouTube is definitely overkill. Since it's normally a good idea to encode with some overhead and give YouTube a higher quality video than it will produce.

My New YouTube Video Encoding Parameters

I started giving YouTube 720p H.264/AAC files with the video encoded at 5.0 Mbps and the audio encoded at 256 Kbps.

I'm exporting my videos with Quicktime and to save fourth dimension, I've only been exporting with a single-laissez passer encoding because I can't run across a noticeable difference between single and dual-pass encoding. I'm using a Flip and a Canon HF100, fairly low-finish cameras, then their image reproduction isn't high plenty quality enough to show much of a difference. If I cease up upgrading to a Canon 60D or 7D, the extra fourth dimension dual-pass encoding takes will exist worth information technology.

The Results?

With this I am able to encode files to approximately half the size I was previously getting from iMovie's defaults. Information technology seems that the files still upshot with the aforementioned quality on YouTube as my ten Mbps videos did and now my uploads also but have half the time. Although, I still wish I could boost my upload speed to something faster than i Mbps.

Here'southward an example of a video I uploaded last month using 5 mbps encoding:

What do you lot recollect? Is there an optimal bitrate that you've establish (perhaps with a more than "scientific" arroyo)?
