10-minute ad at 8 Mbps is 600 MB: over TikTok and LinkedIn caps

A 10-minute video at an 8 Mbps average is 600 MB, which is over the 500 MB cap on both TikTok's non-Spark page and LinkedIn's page, and well under Pinterest's 2 GB. The arithmetic is 8 Mbps x 600 s = 4,800 megabits, divided by 8 = 600 megabytes (TikTok, LinkedIn and Pinterest pages, read 2026-10-09). Sume does not let you set a bitrate, so your levers are length and frame size.

Same file, three caps

The three pages state different size ceilings and different length ceilings. A 10-minute file is inside every platform's length list: TikTok allows up to 10 minutes, LinkedIn 3 seconds to 30 minutes and Pinterest 4 seconds to 15 minutes. Size is what separates them.

The break-even bitrate

For a 600-second video and a 500 MB cap, the maximum average is 500 x 8 / 600 = 6.67 Mbps. Anything above that is over the cap on TikTok and LinkedIn. TikTok also lists a floor of at least 516 kbps, so a 10-minute file must be at least 516,000 x 600 / 8 = 38.7 MB. The usable window on TikTok for a 10-minute ad is therefore about 38.7 MB to 500 MB. See the 6.67 Mbps post for the TikTok-only version.

What you can do in Sume

Sume's timeline and trim refuse codec, crf and similar fields, so you cannot ask for 6 Mbps. You can change what the encoder gets. A smaller output width and height, such as 720x1280 instead of 1080x1920, gives the encoder fewer pixels. A shorter cut also scales the size down in proportion: 8 Mbps for 300 seconds is 300 MB, under both 500 MB caps.

So the options, in order of effect, are: a shorter cut, a smaller frame, and a lower frame rate such as 24 or 25 instead of 30 or 60. None of them is a guarantee, since the final bitrate depends on content. Render, read the file size, and repeat if it is over.

Each render has a price. A 10-minute timeline render is 10 x $0.10 = $1.00, and a trim is $0.02. A retry on the timeline costs another $1.00, so test the smaller frame on a short clip first, at $0.10 per started minute.

Which platform to choose

If the video is long and heavy, Pinterest's 2 GB cap is the loosest of the three. But Pinterest's page also recommends 6 to 15 seconds for video ads, so a 10-minute Pinterest ad is allowed, not recommended. For the wider comparison, see the six-platform bitrate ceiling table.
