Any software just to trim and save video as it is-without rendering

Hello guys,

Have some video files of different formats(H264,mp4) and sizes all i want to do is just trim some parts of the clip and save as it is...(without changing its formats and size etc)it seems very simple unfortunately most of the software like Premiere pro etc not able to do this..have to go through all the rendering stuff etc.

Find this topic when googled..

Batch video editing software that can trim without re-encoding - Video Production Stack Exchange

Any suggestion much appreciated..

Thank's

To edit a movie without rendering, you have to cut on I-frames. These are approx every 1 sec - so cuts may not be as exact as you want. I use Avidemux for this - despite the name, it will edit mp4, mkv etc.

see post #4 in this thread for how to trim unwanted start/end parts of a movie clip

Can't DELETE Videos properly using Avidemux ....

with Avidemux, remember to set the output container correctly (to mp4 etc)

Thank's for your time bro,i was using Premiere pro.its high end,but can't believe why they include a simple process..came across told me avs remaker do this have to try, Always i thought (in premiere pro) rendering
a high quality output increases the quality of the file..eg 640 video to 1080p etc,but you have mentioned rendering reduces the quality??!!

What you are talking about - going from 640px to 1080px - is known as upscaling. This is what happens when you watch an SD DVD on a HD TV - the TV does the upscaling. Whilst you can't invent data (ie missing pixels), TV's and some other devices (eg BD etc) can do a half decent job of upscaling, but it can never be as good as a real HD file or BD disk.

Any file conversion does result in a slight loss of quality when re-rendered - that's why it's always best to cut movies on I-frames and just copy where possible. I also use the Adobe CC products, mainly After Effects and Photoshop (occasionally PPro), and while they are very good they can't do a simple I-frame edit like the free Avidemux.

THank you for clearing confusion...I have to read about I frame..etc.

Thank you. I had been using avs4you (no affil) and I see that there is also flimora, both of which are about 60 USD for a lifetime licence, but I wonder if they are not infact Rebadged/ReGUIed Avidemux. There is also Losslesscut which can do multiple clips and is free.

I have Sony Vegas for more complex tasks but I would like to be able cut up longer videos without rerendering.
