Download problems, and their actual fixes.
Most download failures have one of about eight causes. Find yours below — each answer says what's happening and what to do, not “try again later”.
Above 720p, YouTube stores video and audio as separate streams. Tools that hand you the raw video stream give you a silent file — this is the single most common complaint in the category.
Fix: Keavix muxes the two back together before the file reaches you, so any rung in the Video tab already has audio. If you got a silent file elsewhere, re-download it here rather than trying to repair it.
The list only ever shows what the uploader actually published. A video uploaded at 720p has no higher rung to offer, and no tool can create one — anything claiming to "upscale to 4K" is padding the file, not adding detail.
Fix: Check the quality menu on the original video. If it caps at 720p there, that's the ceiling here too.
For high-resolution video the last step is merging the video and audio streams, which happens after the bytes have arrived. Progress can sit at 99% while that runs.
Fix: Give it a few seconds on a long video. If it hasn't finished after a minute, reload and pick a lower rung — merging is much faster below 1440p.
Login-walled Instagram posts and private YouTube videos can't be read without an account, and we won't ask you to hand over yours.
Fix: There's no workaround. If it's your own post, make it public briefly, or download it from the app's own save option.
The source platform rate-limits our server, not you. When that happens, requests are paused rather than failed silently.
Fix: Wait out the countdown shown on the error and retry once. Repeatedly hammering Fetch extends the block.
Most players handle MP4 fine, but some Android gallery apps ignore M4A audio and a few older devices refuse high-profile H.264.
Fix: For audio, pick MP3 instead of M4A. For video, try a 720p rung — it uses a more widely supported profile than 2160p.
Entries that are private, deleted or region-blocked can't be fetched. We skip them rather than failing the whole batch.
Fix: The skipped entries are flagged in the list. Nothing else in the batch is affected.
YouTube only generates the 1280 × 720 version when the uploader supplied a large enough cover. Older videos often top out at 640 × 480.
Fix: Pick the highest row the tool lists. If max-res isn't there, it doesn't exist — enlarging the smaller one won't recover detail.
