Transcoding ROI Economics

The Core Financial Conflict

Newer codecs (HEVC, VP9, AV1) save massive amounts of CDN egress bandwidth because they represent the same visual quality (VMAF score) at a lower bitrate. However, they cost significantly more compute power to encode.

If you encode a video into AV1, but nobody watches it, you just wasted expensive compute time. You must calculate the Break-Even Views metric.

The Formula

Break-Even Views = (Encoding Cost Premium) / (CDN Savings per View)

Where:

• Encoding Cost Premium: Cost to encode in AV1 minus the baseline cost to encode in H.264.
• CDN Savings per View: (H.264 GB - AV1 GB) * CDN Price per GB.

Worked Example

Assume a 2-hour movie. CDN costs $0.02 per GB.

• H.264 version is 6 GB (Total CDN cost per view = $0.12)
• AV1 version is 4 GB (Total CDN cost per view = $0.08)
• CDN Savings per view = $0.04

Now, assume H.264 encoding costs $5, and AV1 encoding costs $50.

• Encoding Premium = $45

Break-Even Views = $45 / $0.04 = 1,125 Views

If this movie will get more than 1,125 views on AV1-capable devices, it is mathematically profitable to encode it. If it will get fewer views, leave it in H.264.

Common Mistakes

• Encoding the long tail: As shown above, unpopular VoD content never reaches the break-even point. Only encode your top 10% catalog into advanced codecs.
• Ignoring device capability: The math assumes 100% of the viewers can decode AV1. In reality, you must adjust the expected views by the percentage of your audience on compatible hardware.
