MPEG Cutter FAQ
Is the part I keep re-encoded?
+
Not if the format allows a stream copy — the data you keep is bit-identical to the source and the job finishes in about the time the upload took. Only a frame-exact cut on a format that cannot do it cheaply needs a re-encode.
How does MPEG Cutter cut the file?
+
Concretely, the cut is made at the nearest keyframe and the streams are copied through, which makes it near-instant; frame-exact cuts need the picture re-encoded, so the tool tells you which one you are getting rather than quietly picking. You set the start and end points on the waveform or the timeline and keep what is between them.
Anything specific to MPEG when trimming?
+
Yes — MPEG-1/2 uses a program stream rather than a modern index, so cuts are aligned to GOP boundaries unless the picture is re-encoded. It explains most of the "the cut is a fraction of a second off" surprises.
Can I remove a section from the middle instead of keeping one?
+
Yes — cut the piece before it and the piece after it, then merge the two results. That is deliberately two steps because it keeps both halves on the fast, lossless path instead of forcing a full re-encode.
What can I upload to MPEG Cutter?
+
MP4, MOV, MKV, WebM, AVI, WMV, FLV, 3GP, M4V, MPEG and MPG. The container and codec are probed before anything runs, so a mixed batch is handled correctly per file rather than assumed to be uniform.
Is there a file size limit on MPEG Cutter?
+
Yes: free accounts process video up to 1 GiB per file, by far the most generous cap on the site; ffmpeg with x264, x265 and libvpx does the work, which is the same toolchain behind most desktop video software. Video is the one family where the cap is high enough that upload time, not the limit, is what you will actually notice.
Will MPEG Cutter lower the quality of my MPEG videos?
+
It depends on whether the job needs a re-encode. Operations that only touch the container or the timeline are done as a stream copy and the picture is bit-identical to the source. Anything that has to redraw frames goes through x264/x265 at a quality level you set, where CRF 23 is visually transparent on most footage.
Can I run MPEG Cutter on several MPEG videos at once?
+
Yes. Uploads queue in parallel, which matters more here than anywhere else because video jobs are minutes rather than seconds. Free accounts run one file at a time; a pass lifts that.
Why does a EPUB site host MPEG Cutter?
+
EPUB.to is built around the open eBook format — XHTML in a zip, reflowable by design, and readable on hardware nobody has thought about the layout for. A book is a zip full of markup, images and fonts, so almost every job people bring to an eBook site is really a job on one of those things. MPEG Cutter runs on the same upload and the same account as the conversions because that is where it is needed.
What should I do with the result once MPEG Cutter is finished?
+
The converter on this site moves books between EPUB, MOBI, AZW3, PDF and DOCX, so a title ends up on whatever hardware is actually going to read it. Doing that after MPEG Cutter means the conversion is made from the version you settled on, not from the one you were still fixing.
Is MPEG Cutter here the same tool the sibling sites run?
+
The engines are shared — the same toolchain, the same workers, the same limits. What a EPUB site adds is a view on reflow: which of these operations a reflowable book genuinely supports, and which ones only make sense on the fixed-layout media inside it. It also starts from one fact about the format this site is named after: the book is a zip of XHTML with a manifest, so the text costs almost nothing and every decision that matters is about the embedded images and font subsets.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is read and nothing is indexed. Free accounts exist for history and batch size, not for access.
