I am new to all this video stuff and this has been a big project, Im still feeling my way around to preserving all these old videos. I have a bunch of family video's and old TV stuff I converted to digital with an elgato usb capture dongle. The VHS tapes they came off wasn't the best quality and I'd like to trim the files w/o loosing quality. I originally thought I could use iMovie to do this, but the resolution of the tapes were only 640x480, and iMovie wants to upscale everything to HD. Plus when I render the final files I am processing the files again and loosing even more quality. Whats my best bet for chopping these files into smaller shows w/o loosing even more video quality? Is there any software out there designed to clean them up?
