Question 1

What’s the difference between a video format and a codec?

Accepted Answer

A video format (like MP4, MOV, or MKV) is the container that holds video, audio, and metadata. A codec (like H.264, ProRes, or HEVC) is the method used to compress and encode the video inside that container. You can often change one without the other, but sometimes both need to be converted for compatibility.

Question 2

Will converting a video lower its quality?

Accepted Answer

It can, especially when converting between lossy codecs (e.g., H.264 to H.264 again). To minimize quality loss, choose high bitrate settings, avoid multiple conversions, and use professional or editing-friendly codecs like ProRes when possible.

Question 3

What’s the best video format for uploading to social media?

Accepted Answer

MP4 with the H.264 codec is widely accepted across all major platforms including Instagram, YouTube, and Facebook. Keep resolution and bitrate optimized based on the platform's recommended settings for the best results.

Question 4

Is HandBrake really free, and is it safe to use?

Accepted Answer

Yes, HandBrake is completely free and open-source. It’s one of the most trusted video conversion tools available for Mac, Windows, and Linux. Just be sure to download it from the official handbrake.fr website to avoid bundled malware from third-party sources.

Question 5

When should I convert H.264 footage to ProRes?

Accepted Answer

When editing in professional software like Final Cut Pro or Adobe Premiere, converting highly compressed formats like H.264 to ProRes can improve editing performance and preserve visual quality. This is especially helpful for color grading and effects-heavy projects.
