At the same time “real life” footage with a lot of textures might require much lower quantizers, especially in dark scenes. Nevertheless material with few textures, like Anime and Cartoons, can cope with much higher quantizers. A quantizer of 22 seems to be reasonable for most purposes. Using a quantizer higher than 32 will result in almost unwatchable video. Using a quantizer lower than 16 usually is overkill, except for mastering purposes. Nevertheless a quantizer setting in the range between 16 and 32 should give satisfactory results in most cases. Furthermore the quantizer setting highly depends on contents of your video. Remarks: Choosing the proper quantizer setting for a CRF (or QP) encode is not trivial! That's because visual quality is highly subjective: What some people consider “good quality” other people will consider “horrible quality” - and vice versa. This should give approximately the same file size as before, but better visual quality! Another important advantage of CRF mode is that it will benefit from adaptive quantization, something that QP mode can't do. When switching from QP to CRF mode, you may want to slightly lower the quantizer. It's recommended to prefer CRF mode over QP mode, although CRF is a bit slower. Therefore the CRF mode should give the same subjective quality as QP mode, but it usually achieves a significant higher compression. For example it will raise the quantizers in “fast” scenes where the loss won't be visible anyway and lower the quantizers in “slow” scenes. The advantage of the CRF mode is that it suits the human perception much better than the QP mode. Internally CRF mode uses the same ratecontrol algorithm as x264's ABR mode, only without a target bitrate. To be more precise, this mode encodes at a constant “rate factor”, which is derived from the specified quantizer. It basically works similar to the QP Mode (see above), but it will encode with an average quantizer instead of a constant one. When the process is complete, click on the " Download MP4" button to save the compressed file to local drive.Single Pass - Constant Rate Factor: This mode is also known as the “CRF Mode” or “Constant Quality” mode. You have to be patient for the conversion. Now, press " Compress Now!" button to upload and reduce video size to 5MB online. Choose " Target a file size (MB)" in the " Compression Method" drop-down list. Then click on " Gear" button to open " Advanced Options (Optional)" window. It even allows you to upload a video file from Dropbox, Google Drive, or an existing online URL. Press " Choose Files" button or just drag & drop a video file from your computer or other devices to the dotted box area. Open your preferred web browser and go to the FreeConverter website: It's easy to use and convenient, but it has a file size limitation and will spend much more time on the uploading and compressing process. It is a free online tool that can compress video to 5MB or less directly in your web browser. If you don't want to download any software, you can use a free online video compressor tool like FreeConverter. Finally, hit the green " Encode" button on the top bar to start 5MB video compressing process. Designate a destination folder to save the compressed video file and name it. A stager can change other parameters at will. Select " Target size (MB)" option and enter a value less than 5MB. Switch to " Video Encoding" tab and head over to " Quality" section. Go to " Container" tab and select " MP4" as the export video format. Click on the " Gear" icon next to the video name to open a new window. You're recommended to choose 720p or a lower resolution. Open the drop-down list of " Encoding settings" to choose a preset. Run VidCoder, go to " Open source" > " Open Video File" to add your source video. NET 6 Desktop Runtime is required to make it work. Download VidCoder Installer or Portable from official website. In order to compress a video to 5MB or less using VidCoder, follow these steps. It's super easy to use and can do just about anything you need it to. Personally, I'd say you gotta give VidCoder a shot. And get this, it can handle all sorts of video formats and even lets you tweak the advanced compression settings like video bit rate, resolution, and audio quality. VidCoder is an awesome, free and open-source software that lets you shrink your videos down to 5MB or less.
