Atem Televison Studio - Cut/Trim H.264 files

Does anyone know if it is possible to cut or trim h.264 files generated by Atem Television Studio without the need to re-render?

We are using it to capture the sermon in our worship service. I would like to trim edit the video as quickly as possible (just to cut at beginning and end) to get the file uploaded to Youtube and Vimeo.

I've tried on several softwares like Vegas but I can not keep the parameters of the original file after cutting a part of the beginning and end of the recording. Thus the result is that the generated file has parameters different from the original file that takes too long to render.

Can someone help me?

I´m a newbie in production.

Thanks in advance

Hi,

I use H264 encoders to record Church conferences etc and use Quicktime on a Mac (you need Pro or 7 if it is an older Mac) to trim and save as. It is fast and works fine. We are running at 720P.

Just give it an in out and save as not export to!

I use the same method as Tony. We do the same thing to podcast our weekend services.

I do use ffmpeg command lines for that and works great. I do the job with a gnu/linux machine but I think is ok with windows as well. An example of my usage:

$ ffmpeg -i video.mp4 -vcodec copy -acodec copy -ss 00:00:00 -t 00:00:04 trimmed_video.mp4

after -ss is the start of the trim and after -t is the time the new video trimmed will be.

this is a very quick way of doing that and it does not re-encode!

Cheers
