simple merging of two video files

I have a video that is split between two files and all I want to do is join them together into one video but when I have tried it, the quality of the output is pretty bad. I've tried all the format settings and things but surely there should be a quick and simple way of preserving all the existing formats and just splicing the two together?

(I am a complete novice to video editing and bought this to sort out all my home videos into neat films)

What kind of files are they? Vegas can "smart render" a very few types of files, mostly MPEG2 or DV. This is the only way to get no loss of quality in Vegas. All other file types get recompressed when rendering so there will always be a loss.

There are other programs that can do lossless splitting and splicing, but they're not Vegas. VideoRedo is one of the common ones, but even it is somewhat limited in what it can handle.

If you can put up with a break in the sound and video where the two files will be spliced together you can use the DOS copy /b command. I've used this to concatenate many .avc files into one .avc file a number of times and, providing the files have video with the same resolution it works fine, with no loss of quality.

In order of preference:

1. Use the software that came with the camera to join the files.
2. Use VideoRedo, which has a free trial.

Shouldn't we know what these Video files are?
e.g. Straight out of the camcorder....m2ts - or whatever?
Do they play correctly when placed on the timeline, ie separately? ( This proves they are correctly imported--linked into the Program.
When do the not play correctly?
Are you Rendering them ( using a setting like "Match Media Settings"
Are the frame-rates matched for playback?
( You should get away with Camcorder=30fps and 50fps-playback since the Rendering process will do its best to fix any missing bits.) - but it's not ideal.

FWIW
Don't recall having any issues, when importing a long "Bird-table watch" which went over the 4G file-size - which I then edited down to a few fleeting moments . ..I'm sure that session was 3-files- although they were rather smaller than 4G and curiously nothing like the same sizes . . . I wondered what made the camcorder choose when to make the "Break"

Good luck.
