The right quality
for the right moment.

A higher resolution can be useful. It can also be a much bigger file than you need. Here’s how to make the choice.

Start with where you’ll watch.

A small phone screen and a large monitor have different needs. A 360p or 480p copy may work for a quick reference, while 720p often makes a reasonable compromise. For detailed visuals on a larger screen, an available 1080p source may be worth the extra space.

These numbers describe the approximate vertical pixel count. They don’t tell the whole story: source quality, compression, frame rate, and bitrate also affect what you see.

The source sets the ceiling.

A downloader can only offer the formats it receives. If a source supplies 720p, selecting “original” does not create 1080p detail. Streamline lists actual available formats and does not upscale your video.

MP4 is a container, not a quality level.

MP4 and WebM package video and audio streams. Playback support depends on the codecs inside as well as your device. If a compatible MP4 option is available, it is often a useful starting point for sharing across devices. Test the file in the player you plan to use.

File size estimates are just that.

Some sources provide an exact size. Others expose only a bitrate estimate or split audio and video into separate streams. A displayed approximate size can change during processing. A lower resolution generally reduces size, but different encodings can produce exceptions.

Separate streams need a little processing.

Some higher-quality sources provide video and audio separately. When the server has FFmpeg and compatible streams, Streamline can merge them. The progress display switches to processing while that happens. Keep the tab open until the file is delivered.
