What is Y4M?

YUV4MPEG2, uncompressed YCbCr 4:2:0 video stream for encoding pipelines — stored as video/x-raw-yuv — uses lossless encoding to handle lossless video processing, codec testing, video production intermediates. Typical file sizes: varies by content.

What is 3GP?

3GPP (3GP) is a multimedia container format for GSM mobile networks, designed for video playback and MMS on feature phones.

When Should You Use Y4M vs 3GP?

Use Y4M When...

Reach for Y4M when your priority is lossless video processing, codec testing, video production intermediates — its uncompromising quality ensures every detail is preserved.

Use 3GP When...

Reach for 3GP when your priority is mobile video, mms, feature phones — its efficient compression makes sharing fast and storage minimal.

Y4M vs 3GP: Key Differences

  • •Y4M uses lossless compression while 3GP uses lossy compression — this is the fundamental technical difference between the two formats.
  • •Converting from Y4M to 3GP changes compression type: lossy source becomes smaller but with some quality tradeoff.
  • •How transparency is handled: 3GP does not support alpha channels — transparent areas in the source will become opaque.
  • •3GP files tend to be differently sized than Y4M
  • •Primary audience: Y4M is built for lossless video processing, codec testing, video production intermediates scenarios, while 3GP focuses on mobile video, mms, feature phones — pick the format that matches your output requirement.
