I have several videos I've transferred over from VHS to digital. All are
in MPEG2 format. I need to cut and edit some of them, but I'm having
trouble finding a free editor that does so without re-encoding.
Suggestions for freeware that would allow this without a re-encode would
be welcome. Thank you.
Can I add a related question, please??
After copying many VHS tapes to digital, when I edit the Digital files,
cutting out unwanted bits, I would want to add Date/Occurrence "slides" to
the edit, e.g.
Dora's 21st Birthday
First of April, 1999
Central Park, New York
Or, maybe ...
Wedding of
Dick and Dora
St Patrick's Church
Sydney, Australia
21/12/1995
That type of thing ... at the start of, or between scenes for, say fifteen
seconds.
Is this possible and, if so, which program would you recommend??
Hmm. You could use something like Adobe Premiere for inserting the still
captions (either between clips or overlaid on the start of a new sequence)
and just take the performance hit of having to re-encode the whole project.
Or you could use FFMPEG to generate a short MPEG clips consisting of
sequence of stills (which are all the same), and then insert that between
the existing clips. I've done the latter with a DVD that I made for someone.
I may actually have used Premiere to generate the caption segments, rather
than using FFMPEG, but I still joined those to the video clips with
VideRedo.
To make an MPEG from a sequence of stills, you use "ffmpeg -f image2 -i
image*d.png -pix_fmt yuv420p caption.mpeg" where the caption stills are
called image1.png, image2.png etc. The "-f image2" says "the input files are
PNG" and the "-pixfmt yuv420p" tells FFMPEG to force the output frames to be
YUV (luminance and two colour difference) when the input stills are RGB (PNG
stores pictures as RGB). If your stills are JPEG, you may get away without
either of those extra parameters.
You *may* get away with using AVIdemux instead of VideoRedo, but you may
fall foul of AVIdemuxe's rather naive way of joining video which doesn't
recode frames around the edit point and so may lead to brief pixellation if
the separate sections are not on full-frame boundaries and are instead
difference-from-the-last-full frames.
