Depends on input length. A 1–2 minute 1080p clip compresses to 25 MB with almost no visible loss using H.265. A 10-minute clip squeezed to 25 MB will look noticeably softer — you'd be better off cutting first or sharing a link.
About 4–6 minutes at 1080p with H.265, or 8–12 minutes at 720p. The compressor will warn you if your input is too long for the target size and recommend either a higher target or trimming.
No — we hand back an MP4 to your dashboard. From there you download it and attach it in your email client.
No. YouPro doesn't add a watermark on any plan — the output is the same MP4 paid users get.
