The video did well. Now it needs to be a website hero, a 9:16 cut for Reels, a still frame for the newsletter, and a quote card for the deck — and the only copy anyone can find is the one on the company's Facebook page.
This is the ordinary reality of small-team content work, and it is where a lot of quality quietly disappears. Not through one catastrophic decision, but through a series of small ones: exporting from the wrong source, guessing at bitrate, cropping without a plan, and re-encoding a file that had already been re-encoded twice. Here is what actually matters, in the order it matters.
MP4 is a container, not a format
The single most useful clarification in video: .mp4 tells you almost nothing about the file's quality. MP4 is a container — a box holding a video stream, an audio stream, and metadata. What determines quality and compatibility is the codec inside.
- H.264 (AVC) — the safe default. Every browser, editor, phone, and platform handles it. If you export one interchange file, make it H.264 in an MP4 container with AAC audio.
- H.265 (HEVC) — roughly half the file size at similar quality, but patchier support in older editors and browsers. Good for archiving, risky as a delivery format.
- AV1 — excellent efficiency, increasingly supported for streaming, still slow to encode on most machines.
- ProRes / DNxHD — huge files, near-lossless, designed as editing intermediates rather than delivery.
The practical rule: edit from the least-compressed thing you have, deliver H.264. Two MP4 files can differ by a factor of ten in quality, which is why "just send me the MP4" is not a specification.
Bitrate matters more than resolution
A 1080p file at 2 Mbps will look worse than a 720p file at 6 Mbps — blockier gradients, smeared motion, mushy detail in anything that moves. Resolution sets the maximum detail; bitrate determines how much of it survives compression.
This is why "HD" on a download button or an export preset is a weak promise. It describes dimensions, not fidelity. When you have the choice, judge an export by watching the hardest part of the clip — fast motion, a slow pan across texture, smoke, water, confetti — because that is where an inadequate bitrate shows first.
Rough starting points for H.264 delivery, to adjust by content: around 8–12 Mbps for 1080p with normal motion, 4–6 Mbps for 720p, and noticeably more for high-motion footage. Talking-head video compresses beautifully; a handheld walk-through does not.
Every re-upload costs you a generation
Platforms re-encode on upload. Always. The file people watch on a social feed has been compressed at least once beyond whatever you sent, and often twice.
That gives you generation loss: each encode is applied to the artefacts of the previous one, and the damage compounds. Download a published video, re-cut it, re-upload it, download it again, and you are three generations deep — which is exactly how a perfectly sharp original ends up looking like a screen recording of a screen recording.
The rule that follows is simple and worth enforcing:
Always edit from your master. Use a platform copy only when the master is genuinely gone.
When the master is genuinely gone
Which, honestly, is often. Freelancers move on, laptops get wiped, the shared drive gets "tidied." If the published version is the only version left, get the best copy of it you can and treat that as your new source of truth.
For a video published to a Facebook page, the quickest route is to paste the post's link into a browser-based saver and take the highest quality it offers. GetFbVideo does exactly this — resolve the link, choose HD, save an MP4 — which is useful in a design workflow specifically because it needs no install and gives you a normal file that every editor will import rather than a screen capture.
Two things to be clear about. First, this is a recovery step for your own material — your page's uploads, your client's content with their sign-off, or footage that is licensed for reuse. Second, the file you get back is the published copy, not your original: it has already been compressed once. Cut it as little as possible, export once, and do not run it through another round of "optimisation."
Match the shape to the destination
Cropping is not free. Turning a 16:9 landscape edit into a 9:16 vertical cut discards roughly two-thirds of the frame width, and whatever composition you carefully built goes with it.
- 16:9 — website embeds, YouTube, presentations.
- 9:16 — Reels, Stories, TikTok, vertical feeds.
- 1:1 or 4:5 — in-feed social, where 4:5 buys extra vertical space on phones.
If you know a piece will be repurposed, frame for it at the point of shooting or animating: keep the subject and any text inside a centre-safe area so a vertical crop still works. Retrofitting is possible — reframe with motion tracking, or letterbox onto a blurred background plate — but both are compromises you can avoid for free by planning the crop before you shoot.
Keep text out of the outer 10% of the frame on every axis, too. Platform UI overlays, progress bars, and profile chrome sit exactly there.
When you only need the audio
Plenty of repurposing does not need pictures at all. A recorded Q&A becomes a podcast segment; a customer testimonial becomes a transcript, a pull quote, and a caption file; a workshop recording becomes a voice-over bed.
Most savers will hand you an MP3 directly, which skips an export step. Bear in mind MP3 is lossy and one-way, so keep the video file as the authoritative source — extract audio as an output, never as your archive. For serious audio work, pull WAV out of the video in your editor instead.
Compress once, at the end
The most common self-inflicted quality wound is repeated re-exporting: an export, then a "make it smaller" pass, then a platform-specific pass, each one compressing already-compressed video.
Work the way you would with images — the logic is identical to the one in our guide to exporting images for the web without losing quality. Keep a high-quality master, produce each delivery file from the master in a single pass, and never chain exports. If a file needs to be smaller, go back to the master and export again at a lower bitrate rather than re-compressing the delivery file.
Name and archive it so it survives
A repurposing workflow is only as good as your ability to find the source in eighteen months. A convention that holds up:
brand_topic_YYYY-MM-DD_v01_master.mp4
brand_topic_YYYY-MM-DD_v01_1080p-web.mp4
brand_topic_YYYY-MM-DD_v01_0916-reels.mp4
Keep masters and exports in separate folders so nobody edits from a delivery file by accident. Store the masters in two places — a local drive and cloud storage — because platform hosting is not a backup. Accounts get locked, pages get merged, and export tools change. The copy you control is the only one you can count on.
Frequently Asked Questions
Should I export H.264 or H.265?
H.264 for anything you are delivering, because compatibility is universal and the file-size saving from H.265 rarely justifies a client who cannot open it. H.265 is a reasonable choice for archiving your own masters on your own storage, where you control the playback environment.
Why does my video look fine locally and terrible after upload?
The platform re-encoded it. You can reduce the damage by uploading at the platform's preferred resolution and a generous bitrate, avoiding heavy grain or noise (which compresses badly), and never uploading a file that has already been through a compression pass.
Is it better to upscale a 720p video to 1080p before uploading?
No. Upscaling invents pixels rather than recovering detail, and it hands the platform's encoder a larger frame with no extra real information — which usually means a worse result at the same bitrate. Upload at the resolution you actually have.
Can I re-edit a video I downloaded from a social platform?
Technically yes, and it is a legitimate move when it is your own content and the master is lost. Just accept you are starting a generation down: cut conservatively, avoid heavy colour grading on already-compressed footage, and export once. And keep it to material you own or have clear rights to.
The Bottom Line
Most video quality is lost to process, not to equipment. Understand that MP4 is a box rather than a guarantee, judge exports on bitrate rather than resolution, plan your crops before you shoot, and — above all — always work from a master rather than a platform copy.
If you cannot find the master for your best-performing video, fix that this week. Save the published copy with GetFbVideo at the highest quality available, file it under a proper naming convention, and back it up twice. It is a worse source than the original, and it is infinitely better than having no source at all.
