Question 1

What formats can I drop?

Accepted Answer

MP4, WebM, MOV, AVI, MKV, and most common clips. Output is MP4, WebM, or GIF.

Question 2

Is quality kept?

Accepted Answer

MP4 uses H.264 with quality-minded settings. WebM uses VP8. GIF is a short, small preview.

Question 3

How does GIF conversion work?

Accepted Answer

The first 10 seconds at 10 frames per second, scaled to 480 pixels wide.

Question 4

Is there a size limit?

Accepted Answer

Memory is the limit. Many machines handle 200 to 500MB. Larger files may fail.

Question 5

Why is the first run slow?

Accepted Answer

The engine is about 30MB and downloads once. Later visits use the cache.

Question 6

Does the video leave my device?

Accepted Answer

No. Encode runs in the browser.

Question 7

Should I compress instead?

Accepted Answer

Yes, when the file already plays and is only heavy.

Question 8

Can I pick a custom bitrate?

Accepted Answer

No. You pick an output format. Use Compress Video for size presets.

Question 9

Will audio survive?

Accepted Answer

Audio is kept on MP4 and WebM in the usual case. GIF has no audio.

Question 10

Can I convert only part of the clip?

Accepted Answer

Only GIF is clipped to 10 seconds. MP4 and WebM convert the file you drop.

Question 11

What if I have a raw H.264 stream?

Accepted Answer

Use H.264 to MP4.
