The compression comparison is great! One problem... Quality is 144p, can't even see what is going on in the video. Any ETA on this problem?

@FidelHen For now you can just set the quality yourself using
final compressedVideo = await VideoCompress().compressVideo(
videoPath,
quality: VideoQuality.HighestQuality,
);

@Serdnad I did that and it still looks terrible. It's all super pixelated.

Hmm, weird, I'm using that code in my app right now and adding that line fixed things for me. You're on iOS, right?

Which device are you using?
This is not on our side, it is on Apple's side. I could create fixed size and quality presets, but apple recommends using
AVAssetExportPresetLowQuality
AVAssetExportPresetMediumQuality
AVAssetExportPresetHighestQuality
Rather
AVAssetExportPreset640x480
AVAssetExportPreset960x540
AVAssetExportPreset1280x720
AVAssetExportPreset1920x1080
AVAssetExportPreset3840x2160
I am changing the size to medium by default, but it will not help you if you are trying to compress a video from an iPhone 5 for example, it will obviously be pixelated, because iOS defines what is "low, medium and high" quality according to the device used.
I can try to make the sizes fixed, but if I do that and you use the highest preset on an iPhone 11 PRO and send a video to an iPhone 6 it is very likely that the video won't even open due to lack of resolution support on the device.
We are using the iOS API to compress video, basically any converter within the AppleStore uses exactly the same API (since it is not possible to use FFMPEG on the AppleStore due to the GNU license). Presets are defined by Apple, it's not like Android that if you want a 48x96 video you can have it. So if something is not working as it should, you can open an issue on the Apple forum.

Fix on version 2.0.0

DefaultQuality seems to output similar video as LowQuality preset does. This bug still continue for me.
