How to Enhance Video Quality Online With AI

An AI video enhancer rebuilds a soft or compressed clip and writes it back at a higher resolution. On Aihangsoft it upscales to 720p, 1080p, 2K or 4K, with optional noise reduction, sharpening and a frame rate change. It is a Pro tool, so the video is uploaded to Volcengine AI MediaKit for processing.

The limits matter as much as the feature list. A run accepts a file of up to 200 MB and 5 minutes, the charge is based on the output length, and a 1080p minute costs about 67 credits. A few settings decide the amount of change, and the model rebuilds detail rather than recovering it, so a badly blurred clip will not turn crisp. The rest of this page covers what the enhancer fixes, what each setting costs, and where it stops working.

A soft clip is missing information, and no model can put back the exact pixels a camera never captured. What an enhancer can do is make compressed, noisy or low resolution footage read more cleanly, and make it hold up at a larger size. Before you upload, two things are worth understanding: where your file goes, and what each run costs.

What AI video enhancement actually does

A video enhancer is a chain of algorithms rather than a single filter, and it helps to separate them, because they succeed and fail in different ways.

JobWhat it fixesWhere it helps
Super resolutionLow pixel dimensionsA 480p or 720p source that has to play on a 1080p or 4K screen
Noise reductionBlocking, grain and colour speckle from heavy compressionClips pulled from chat apps, social platforms or old uploads
SharpeningSoft edges and mild defocusPhone footage shot through a window or in poor light
Colour and contrastFlat, washed out or faded colourOld recordings and footage that was graded badly
Frame rateChoppy motion and a low frame rateAIGC clips generated at 24 fps

The first four change how the picture reads. The frame rate option is different: it interpolates new frames between the existing ones, which smooths motion rather than adding detail, and it is the setting that doubles the cost of a run.

Rebuilt detail, not recovered detail

The fast tool on Aihangsoft is a lightweight super resolution and enhancement model, not a diffusion generator. That distinction matters. It predicts the most likely edge or texture where detail is missing rather than recovering the original pixels, which is what lets it clean a picture up without inventing a new scene.

It still cannot restore information that was never recorded. A clip that is genuinely out of focus, extremely dark or crushed by repeated re-encoding improves far less than a slightly soft one. Expect a cleaner, steadier picture, not a different one.

This is a Pro tool, and it uploads your video

Aihangsoft has 45 browser tools that process a file on your own device and never transmit it. The AI Video Enhancer is not one of them, and it is also the one Cloud AI tool that is limited to Pro. Both facts are worth stating plainly before you start.

The reason for the Pro limit is cost. Every run is billed by Volcengine, and a single minute of 1080p output is expensive enough that giving it away on a free daily allowance is not viable. A guest or free account sees the upload area locked and a link to the plans, and nothing is uploaded or charged in that state.

On the privacy side, the result of a Pro run is stored on our server for 24 hours and then deleted automatically. That window is a retention period, not a promise about logs or backups. Apply the rule you would apply to any online converter: do not upload confidential footage, private client work or anything you would not email to a stranger.

What a run costs

The charge is based on the length of the output and on the resolution and frame rate you choose, which is exactly how the cloud service bills the job. The table below gives the cost per minute of output at each setting.

Output resolutionCredits per minute at 30 fpsCredits per minute at 60 fps
720pabout 34about 68
1080pabout 67about 134
2Kabout 134about 268
4Kabout 267about 534

Pro includes 1,500 credits a month, so the same allowance buys roughly 44 minutes of 720p video, 22 minutes of 1080p, 11 minutes of 2K or 5 minutes of 4K, all at 30 fps. Doubling the frame rate halves each of those figures, which is why the frame rate choice is a cost decision as much as a quality one.

Two safety nets are worth knowing. The rate is charged on the output length the service actually produces, and credits are only deducted once a result exists. A file that is rejected for length or size, a clip that exceeds the limit on your plan, or a run that fails at the cloud service costs nothing.

The practical reading is to match the resolution to the destination rather than always reaching for the highest. A clip made for a phone screen rarely gains from 4K, and 720p is often enough for a preview or a draft. Reserve 4K for a large screen or a final delivery where the extra size is the point.

How to enhance a video in three steps

  1. Add your video. Drop an MP4, MOV, MKV or WebM of up to 200 MB. A run can cover up to 5 minutes, and the input has to sit inside 2K. The file is uploaded to our server at this point, so do not send anything you would not want processed in the cloud.
  2. Choose the output. Pick a target resolution from 720p to 4K, a frame rate of source, 30 or 60, and a bitrate of low, medium or high. The page shows an estimate in credits that updates as you change them, and the server confirms the exact figure when the run starts.
  3. Enhance and download. Start the run and watch the progress. The fast tool works at about three times real time, so a one minute clip is usually done in about three minutes, and a five minute clip can take around fifteen. Keep the tab open, then preview the MP4 and download it.

Because a run is charged from the output length, trimming first is the cheapest way to work on part of a longer video. Our Video Trimmer can cut a clip down to the five minute ceiling before you spend credits on it.

When it is worth it, and when it is not

Lifting AI generated video

Generating at a lower resolution and enhancing afterwards is cheaper than generating at the top size, which is the workflow the cloud service itself recommends. A clip generated at 480p or 720p can be lifted to 1080p, and the frame rate option smooths output that was made at 24 fps. This is the clearest case for the tool.

Cleaning up old or re-shared clips

Footage that has been downloaded, re-uploaded and re-compressed several times accumulates blocking and colour speckle. Noise reduction and sharpening pull some of that back, and the result is usually more watchable than the source. The gain is real but bounded, and a clip that was already very poor will stay poor.

Matching a platform spec

Sometimes the goal is simply a file at a predictable size. Setting the resolution to 1080p gives a standard upload, and 4K suits a large screen or a client delivery. Keeping the source frame rate is the cheapest option, and it is the right choice when the platform does not need a change.

When to use something else

If the clip is too long, trim it first. If it is too large to upload, compress it first. If it only needs a smaller file or a different format, the browser based Video Compressor and Video Converter do that locally, for free, without uploading anything. Enhancement is for quality, not for conversion.

What this tool cannot do

These are the limits worth reading before you spend credits on the wrong setting.

  • It is Pro only. Guests and free accounts cannot start a run, and the upload area stays locked until you are on a Pro plan.
  • It uploads your video. Unlike the 45 browser tools, this one sends the file to our server and to Volcengine AI MediaKit. Do not use it for confidential footage.
  • It rebuilds detail rather than recovering it. A genuinely out of focus, very dark or heavily degraded clip improves far less than a slightly soft one.
  • There is a 200 MB and 5 minute ceiling, and the input must be inside 2K. A longer video has to be trimmed, and a larger one compressed, before it is accepted.
  • It does not change speed, cut, crop, rotate, add subtitles or remove a watermark. Those are separate browser tools, and none of them upload anything.
  • It cannot target a specific file size. The bitrate setting nudges the output up or down, but there is no field that says make this exactly 25 MB.
  • The output is always MP4 with the audio kept. There is no option to strip the audio or to export another container.
  • Processing time scales with length. A five minute clip can take around fifteen minutes, and the tab has to stay open while it runs.
  • Results are temporary. The file is kept for 24 hours and then deleted, so save it rather than coming back the next day.

FAQ

No. Video enhancement is a Pro feature, and it is the only Cloud AI tool on Aihangsoft that guests and free accounts cannot run at all. There is no free trial of this one. Every run is billed by Volcengine, and one minute of 1080p output costs enough that giving it away on a free daily allowance is not viable. Pro is $6 a month and includes 1,500 credits, which covers about 22 minutes of 1080p video at 30 fps, or about 44 minutes at 720p, since a 1080p run costs about 67 credits per minute and a 720p run about 34. A 2K run costs about 134 credits per minute and a 4K run about 267. Credits are only spent when a result is actually produced, so a rejected file, an over-length clip or a failed run costs nothing.
Your video is uploaded to our server, forwarded to Volcengine AI MediaKit, and processed by its fast quality enhancement tool. The service analyses the footage shot by shot, then applies a set of trained algorithms for super resolution, denoising, sharpening and colour, and writes a new video at the resolution you picked. It works at roughly three times real time, so a one minute clip usually takes about three minutes and a five minute clip around fifteen. This is not a plain resize: the model reconstructs edges and texture as it scales, which is why a 720p clip can look cleaner at 1080p than a simple stretch. It cannot invent detail that was never recorded, though. Heavily compressed, badly out of focus or very dark footage improves far less than a slightly soft clip. The output is a standard MP4 with the audio kept.
MP4, MOV, MKV, WebM, AVI and MPEG, with a limit of 200 MB per file and 5 minutes per run. The input resolution must be inside 2K, which means a short edge between 360 and 1440 pixels and a long edge between 360 and 2560 pixels, and a larger source is refused by the service before processing. The length and file size checks happen on our side before anything is uploaded, so an over-length or oversized file costs nothing and never reaches the AI service. To handle a longer video, trim it first with our Video Trimmer, or compress it with the Video Compressor and enhance it in parts. Audio is kept in the output, the container is always MP4, and the finished file is stored on our server for 24 hours. Save it rather than coming back the next day.
Three settings decide the result. Resolution sets the final size, from 720p up to 4K, and it is the main driver of cost: about 34 credits per minute at 720p, 67 at 1080p, 134 at 2K and 267 at 4K, all at 30 fps. Frame rate can stay as the source or be converted to 30 or 60 fps, and because 60 fps doubles the work it also doubles the price per minute, so a 1080p run at 60 fps costs about 134 credits per minute. Bitrate offers low, medium and high to trade visual quality against file size, with medium as the default. The estimate shown in the page updates as you change these, and the exact figure is confirmed by the server when the run starts, because the charge is based on the output length it actually produces.
Yes, and that is the main trade-off. Unlike the 45 browser tools, which never transmit a file, the AI Video Enhancer sends your video to our server, forwards it to Volcengine AI MediaKit for processing, and stores the finished MP4 on our server so you can download it. On Pro the result is deleted automatically after 24 hours. We do not watch your footage, build a library from it or use it to train anything, and it is never published or shared. The file does leave your device, so treat the service like any online converter: do not upload confidential footage, private client work or anything you would not send to a stranger. For work that must stay local, use our browser based video tools, which run entirely on your own machine. They never upload anything and never cost a credit.
