How to re-render sections of a video without re-encoding. Avermedia Live Gamer HD
I record gaming footage with an Avermedia Live Gamer HD capture card and sometimes I capture several hours of footage at a time. I need a way to cut up those long sessions into smaller pieces/files without re-encoding the footage and without any quality loss.
My old capture card, the BlackMagic Intensity Pro, had it’s own codec that I could use to render within Sony Vegas and split up the files without re-encoding. It was a very simple process to just load each .avi file in Vegas and split up my gaming sessions into smaller sections without any quality loss.
So I’m wondering if there is a way to do the same thing with my new capture card that would allow me to quickly split up my gaming sessions into smaller parts so that I can save only what is necessary. I need to figure something out soon as I have nearly 10TB of raw gaming footage that I need to sort through and I will probably only end up using 2TB of the footage so being able to split these files up is really essential as I’m running out of HDD space.
I don’t think that Avermedia has it’s own codec like the BlackMagic card did but I could be mistaken. The capture card saves the footage as an .mp4 file and I’m recording 1080p footage @ 30FPS.
Any suggestions I could try as far as splitting the big files up would be greatly appreciated.

i guess you will not be able to do it in vegas. only few pro formats may be cut and saved without reencoding. i d say you rather need another program for chopping video files. vegas is rather for editing and postproduction. it accepts many input formats but most of them must be reencoded on the output.

Thank you for your input, do you have any idea what type of programs would accomplish what I’m talking about?

i focused on what you asked for but i am thinking beyond that now. what do you mean “you need no quality loss”. are you gonna upscale it to 4K for the movies or what? just import whatever you have into vegas, chop it as you like and render to mp4. it will look perfectly the same and it will probably be much lighter, with appropriate settings no one including you will be able to say which is original and which recompressed. you really do not need to go lossless to keep very good quality.

The issue is not so much maintaining the quality, although lossless is ideal. The issue is that in order to render each clip (usually 20-45min in length) it takes me about 15 minutes of render time. In order to sift through 10TB of footage and wait 15 minutes each section I would be cutting and rendering all week just to get through all of the footage.
That’s what was so great about my previous capture card. Using the BlackMagic codec I could cut the footage up into sections and it would only take ~30 seconds to split up each part.
